Our newborn loves to sleep on her side. This gave us the option of swaddling while also giving her the comfort of being on her side with her arms/hands next to her head.

I bought this for our 2 month old b/c she started fighting the traditional swaddle and wanted her arms out. However, if her arms were totally free, she would keep herself awake. I had heard about Nested Bean and decided to give it a go, and she LOVES it!
She no longer cries when putting her down for naps, and sleeps about 15 min longer. I have noticed that she also falls asleep faster.
I would definitely recommend this to any parent!
Also, she chews on the hands a lot and it seems totally safe. I was concerned about it wearing out but it hasn’t been an issue so far.
Xenica Y.
Great for keeping my little one asleep. We cycle between halo, nested bean, and swaddle blankets, and he always sleeps better in the nested bean.
I do think it runs a little small, as my son is only 2 months old but completely fills out the 3-6 month range.

Had helped my daughter self soothe much easier! I’ll be getting this in the future for all of my friends who are expecting.

It took a couple nap times to get her used to this new swaddle. After a couple days we tried it at bed time. She has been sleeping 4-5 hour stretches previously, but with this swaddle she slept for a 7 hour stretch. I thought it was a one time thing so I didn’t hold my breath. It’s been 3 nights and each night the first stretch is 7 hours and the next one has been increasing from 2.5 hours by 20-30 minutes each night. I am extremely happy with the results. Now I need to protect the getting her to sleep easily part, because once she is asleep we are good to go.

I wanted to love this and I wanted it to help with sleep but it just didn’t. My baby is four months old and has always been in an arms up sleeper (Love to Dream) so when I saw these I thought she would like them too with an added comfort of the weight. I had a couple problems with them right off the bat. The picture I added shows inside the sleeve part where the zipper is sewn on. The hard zipper edge is poking out on both sleeves. I had to cut them because the sealed/melted edge is so sharp it would irritate my baby’s armpit area. We have to have her in a long sleeve onesie still or she’s red in the morning. There are also a couple QC issues with the stitching (it looks like the fabric was folded a bit when the machine sewed the Velcro swaddle part and the weighted part) so there is a small fold in the fabric. It doesn’t affect the way the sack works, but for the price of this thing I’d expect better… Also, the mesh sleeves do not keep heat in. I guess to me it looked like different material in the picture, but when she wakes up her arms/hands are freezing. We keep the room around 68 at night so it’s not freezing, but the mesh allows for too much breathability/heat exchange. As for the weighted aspect, it didn’t improve her sleep length as I thought it would but every baby is different so I don’t fault the sack for that. Overall, I wouldn’t buy another one. I’m going to keep trying to find that perfect sleep sack, but for now will be using her original ones.

Our little one loves nested bean - we recently transitioned him to daycare where he has to be arms out and this is the one sack that seems to be working.
Tara N.
We love our Nested Bean! Our guy can self-soothe by sucking on his hands, has a good range of motion but also feels snuggled so that he can sleep well.
Jessica P.
Went from waking every two hours to doing a 5-6 hour stretch! I use another swaddle underneath this one as well because she's a Houdini and busts out of the center piece that wraps around sometimes.
Kylie A.
This swaddle saved our lives! Our LO was taking hours to get settled and go to sleep and is now falling asleep in a few minutes!
Kryssa V.
Our little one likes to have her hands up when she sleeps so she can touch her face. The mesh sleeves have worked amazing for us!
Chelsea R.
Only swaddle we use now!
Jessica f.
Bought at 3am when my newborn was screaming in the Snoo. Like most babies he wanted his hands up. This swaddle really did calm him and he sleeps really well in it most naps and occasionally will do this over the Snoo at night.
Emily M.
My 2 month old loves to have her hands by her face so this swaddle was made for her. She’s sleeping 6-8 hours some nights!! I can’t believe it.
Melissa R.
My 3 month old consistently sleeps 4-6 hour stretches and wakes up quietly and happy in the morning.
Jaclyn G.
Bought this for our 7 week old and it helps to keep her settled while she sleeps. We have also noticed longer stretches of sleep overnight because she is no longer startling herself awake. Would definitely recommend this product.
Madeline T.
This swaddle really does the trick! My baby loves to have his hands by his face when he sleeps so the upper arm placement is perfect. The first time we put it on him almost immediately his eyes grew heavy and he was falling asleep in minutes!
Rebecca E.
Babe loves it. Game changer to get her to sleep and stay asleep!
Coralys R.
I am so sad I discovered it when my baby was about 8 weeks! I would’ve loved to have this with him as a newborn. It’s super simple and easy to use. With the other swaddles he would get to warm and this was perfect for our room temperature. I used it with his hands in at first and then transitioned to having his hands up. Now we have the next size up. Loving this swaddle!
Coralys R.
My little one loves to sleep with his arms up. This is a happy medium, since he is able to move his hands comfortably. He will usually sleep 6 hours straight using this swaddle, I absolutely love it!
Mackenzie J.
I have been telling everyone about this sleep sack. My 8 week old daughter has been averaging 8-9 hours of sleep straight through the night ever since using the sleep sack. Very pleased with this product and will be buying from this company again in the future!
Lauren B.
My son slept so good in this as a newborn that we had to buy the next size! He is being transitioned out of the swaddle all together and being able start the transition with one arm is working wonderfully. I will definitely be buying the zen sack and am contemplating gifting a bundle set to one of my expecting girlfriends! These sleep sacks are the best.
Bethany N.
Our daughter sleeps so well with her Nested Bean sleep sack. Can’t imagine life without it.
Jessica P.
We ordered these for when our baby comes in March so we haven’t tried it yet however it seems like good quality! My only complaint is that upon opening the package the swaddle smelled HORRIBLE, like manure almost. We washed it and the smell went away but we ordered more than one and the other didn’t have the same problem.
Betty .
Bought the zen sleep sack for my grandson to help him sleep through the night. Best purchase ever he loves the egg on his chest and falls asleep quickly, stays asleep longer.
Kristine L.
Son was almost 9lbs when born so I purchased the 0-3 mo but I personally feel like it’s a little extra snug? But maybe that’s shay it’s supposed to feel like? Just seems like he’d outgrow it pretty quickly since he was born at 21 in also. Overall I do like the nested bean and would recommend if you are looking for a swaddle to help your baby sleep.
Alicia M.
Highly recommend this product! We could immediately tell a difference in how well our little one slept. He would fall asleep more quickly and stay asleep longer. Better sleeping baby = more rested mama. Thank you Nested Bean!!
Sal V.
Love our nest bean swaddle! Used the original swaddle for my first daughter and she loved it as well!
Michelle S.
My son never liked to be swaddled and would always manage to break out of it to have his arms by his face. This swaddle was a life saver! The light weight added comfort for him as well. Everyone needs this swaddle. I just ordered this one since he almost is outgrowing his newborn one!
Jen M.
Love it, she sleeps so well
kelsey y.
I was worried about transitioning from a full swaddle to a sleep sack. This does the job. She loves having her hands free to move around instead of down by her sides. We love this!!!
Sanna A.
Best swaddle!
Ellen L.
We really like this swaddle but it runs really small in my opinion! My son is 9lbs and I feel like it's super tight to zip up.
Teresa S.
Our baby is too big for the swaddles. I bought two different sizes, just didn’t fit right.
Daria P.
They are really soft but my baby doesn't like to sleep in it. Also because the baby had 4200g when he was born the 0-3 months is to small for him.
Tiffany L.
I went by the month range and should have gone by weight. My little guy is about to outgrow his newborn size after barely using it.
Nevena R.
It is great thing that made my boy sleep 7 hours when he was 8 weeks. But unfortunately, he only wear this size for 5 days and becomes small
david c.
The fit was too tight for my one month old
Tricia M.
Really like this sleep sack! The arms up while still feeling swaddled got us through the bassinet to crib transition and beginning of sleep training. We did have to take the arms off at 7 weeks because she was getting so close to rolling over and that just made me nervous. I also don’t agree with the weight sizing - I had to go up to 3-6 months when she was 12lbs even though the 0-3 month size is supposed to reach 13lbs. That’s my only complaint! Love that it’s breathable cotton and the design. Will probably get more as she grows!
Candace s.
He immediately calmed and went to sleep when I put it on him!
Maddy C.
The best purchase I have ever made for my baby! The first time he wore it he slept 5 hours without waking up, which was a huge win for mom and dad!! Definitely recommend this for your little one!
Tejal S.
My son has been sleeping better with this swaddle. I highly recommend!
Leah J.
I love this weighted sleep sack so much. I noticed that the webbed net arms really help instead of having the arms wrapped against her body. She tends to get better rest this
way! So thankful fir this and would definitely recommend ☺️
Taylor F.
Loved it! Baby went from crying 4 hours at night to sleeping 7 hours straight in 3 days.
Angelica S.
Amazing customer service and an amazing product! Have been telling everyone I know this product is amazing!!
Jessica A.
My son born 5lbs after 3 weeks old hated to be swaddled. So was recommend to try this. But was was not 7lbs until he was just over 5weeks. So I finally tried this product. Great quality, but my son still did not like the arm constraint so I removed, but he still did not like it. I waited til he was 9lbs then tried without the arms again. I do see it helps a bit. Perhaps if your child is born over 7lbs and you use the product starting in hospital or at least immediately at home you may get better results.
Tabitha S.
Great product
Melodie C.
Once our 6-week old switched to this swaddle, he started consistently giving us 3-4 hours at the beginning of the night. The only issue I have is that his arms don’t fit in the part intended for the hands-up position — maybe he has long forearms? Hoping this lasts a little longer so he can transition to arms out before we have to purchase the next size up.
Ella M.
I’m so happy I discovered Nested Bean! I was struggling with getting my little one down for naps. I’d get him rocked to sleep and then when I went to lay him in his crib he’d jolt awake. With this new swaddle I don’t have nearly as many issues with this as I did before using it. The weight really helps with transitioning him onto his bed. Even if he stirs, he’s much easier to get back to sleep because of the weight of the swaddle. Recommend to anyone who has this issue!
Angie J.
Never used the swaddle for the arms but really like the weight of it. Very soft bamboo
Brandi M.
Love it. It’s my son’s favorite swaddle. We just sized up to the 3-6m one.
Kelsey S.
Perfect transition from arms down swaddles to this before going into a sleep sack!
Shalan J.
Helped baby stay asleep .
Kayla B.
The same night we used it our little man almost immediately stopped fussing and went to sleep. Getting a good 6 hours through the night! We all love this and so happy we went with this swaddle!
Kyleigh M.
Love this sleep sack/swaddle. While my 1 month old still wakes up in it, he seems to have an easier time calming back down. The arm pieces were a little small for him, but his arms are pretty long. I don't know if I'm going to go with a sleep sack or another zen swaddle for the next size. I think it's worth a try and worth the investment.
Tiffany R.
Love the nested bean swaddles. My babies have always slept the best in these. However, I bought the wrong size and immediately tried to contact customer support and change it and just kept getting the run around of emails and ended up receiving the wrong size. Otherwise, love nested bean and will continue to recommend these swaddles and sleep sacks to all my friends
Athena H.
My two week old didn't like her arms swaddled. We tried the Nested Bean Zen One and I think she loves it. She only wakes once a night!
Lauren B.
The best thing for helping my little one stay asleep!
Renee R.
Love this perfect for transiting from swaddle to sleep sack buy my only complaint is when I washed it the first time I got two holes on the seams
Gina M.
I LOVE this swaddle, it’s the best out there, BUT…I’ve bought two of them and both came unstitched in the front where the legs go. Exact same area in both swaddles. For the price of these I don’t expect to have to sew them myself.
Emma M.
I don't know what I would do without this swaddle! Our baby flails and wiggled free from every "regular" swaddle no matter how good someone swaddled him! The nested bean saved our baby and his mama and daddy from sleeplessness! Whoever created this was a genius.
Juree C.
It’s nice! The baby likes it, but I did not get the same result as others, he didn’t magically sleep through the night the first night he wore it. BUT it is such soft material, the light weighted feel is so nice, and I do believe baby boy sleeps comfortably in it. I would purchase again.
Amanda I.
Best thing ever invented. This is the second one we’ve purchased because he out grew the first. We use it for naps and it is an essential part of our bedtime routine. My little guy went from walking every two hours to nurse to sleeping 4-5 hour stretches at night at only 2 months old since wearing the zen one
Kayla K.
BUY this if you enjoy sleep. I wish I purchased this even sooner. My daughter loves it. I’ve already purchased one in the next size up, and I plan on getting more so we never go a night without a clean one available to use. She never liked being swaddled in a blanket, so I was shocked that she loved this so much. She sleeps so soundly and comfortably. She used to wake up every hour…every night! Now, she can sleep up to 5hrs at a time and only wake to eat! Truly the best purchase ever!!!
Anna C.
These are really nice quality. I was hoping to use this to transition my son out of a swaddle since he loves to have his hands up toward his face- unfortunately his arms aren’t even close to fitting in the “wing” area. I just zipped them off and he has been tolerating a 7-8 hour stretch at nighttime between feedings at 7 weeks old. I think this product needs a bit of an adjustment but overall we still love the nested bean sacks.
Jackie H.
I JUST got this in the mail today, he's had two naps with this and already there's such a difference! He always manages to get his arms out of my swaddles, no matter how tight and loves to sleep with his arms up by his head. But he startles himself awake A LOT. Those little wings are freaking perfect for the way he likes to sleep! They keep his arms from flailing and waking him up but allow him to sleep in the position he prefers. Now I can rest and get naps in myself! Ugh!! Love, Love, LOVE IT! ❤
Lauren G.
I tell EVERYONE about this! It’s so versatile and transitional in that you can do arms in, one arm out, or both arms out. The weighted sacks must be in the perfect places for comfort and security because my little one’s sleep has improved tremendously with this purchase!
Megan D.
Love this sleep sack! Just wish they made them in a bigger size. My 3+ month old is long. Her legs are about to push through the bottom and her arms are too tight in the alotted space now.
Katelyn P.
It’s nice you can swaddle arms however you want
Tejal S.
It keeps our 2 month old cozy and I believe he feels more secure so he sleeps well at night, we use it for his day time naps! I like the mesh flaps as he likes to keep his hands near his face :)
Kassidy K.
Best swaddle hands down! You will not waste your money! Just buy it now!
Stephanie M.
Customer service is absolutely fantastic. We originally bought the 0-3 month based on our babies weight, but she ended up being too tall & needed a size up. They shipped out the next size up right away which was super helpful. The weight in the product was still a proper ratio for her based on our research, so we felt ok to use it for supervised sleep at first, and have now been using it at night.
The removable mesh sleeves have really helped us with transitioning her out of the swaddle stage, and she just slept a 9 hour stretch after about a week. She still has difficulty connecting her sleep cycles when napping, but we are very grateful she is starting to turn around her night time sleep.
Was very nervous about using a weighted product, but after doing some research, we felt that this particular product was safe. Also washes well & the material is really nice. We are hoping we have continued success with the Zen One & can successfully buy the Zen Sack when she is ready!
Samantha W.
It was cute and well put together. My daughter was not a fan. The swaddle would twist and bunch really bad around her neck. It's also really small. My baby is tiny and this swaddle clung to her and she was 7 lbs.
Bailey N.
I loved this product at first! My son was able to sleep for a longer periods during the night.
After three washes the stitching around the chick, that forms the weighted center, came undone. The swaddle is lumpy and not weighted properly anymore. Really disappointed considering how expensive the swaddle is you'd think it would hold up better.
K p.
Nested bean is too small for my four month old son . I ordered 3-6 month for him but still too small . He kind of likes it but I prefer it to be a little bigger.
Chelsea G.
This has helped my little babe sleep through the night with no interruptions! The other swaddles don’t even compare!
Ana A.
The only draw back is that the arm slots are slightly too small for my son. I wish he had more room. His wrist are flexed in the slots.
Marie T.
My newborn baby loves her swaddle. She is now sleeping through the night.
Trinity G.
I used to have to have my hand on my daughters chest for her to fall asleep. Thanks to the weight, she falls asleep without my hand!
Katie D.
This product is amazing. It calms my granddaughter down as soon as she gets in it!!!
Kandice F.
My little loves sleeping with his nested bean! We went from being up every two hours to 4-5 hour intervals!
Leah R.
Because my daughter likes to sleep with her arms out and up and to suck on her hands etc I thought this would be a good alternative as it allows them to still get their hands to their mouths etc..
However, she doesn't sleep any better than with any other wrap, feels like an expensive alternative at this point. Also, the bottom of this doesn't unzip in a way that you wouldn't wake them for a diaper change if needed because you still have to pull their legs out.
The material is nice and thick tho which is nice.
Petie R.
Worked the first night- this is a big deal because up till now, our little one would ONLY sleep nights on my chest.
Lifesaver!
Jessica B.
My daughter liked being swaddled for approximately the first week of her life. After that, she actively started attempting to escape them (and usually succeeded), screamed while we swaddled her, and had to be consoled afterwards. We wanted to stop swaddling, but her startle reflex doesn’t make that feasible. Once she learned to free her arms from the Halo swaddle, I looked into the Nested Bean on the suggestion of a friend of a friend. The Zen One is magic! It’s easy to use and the material is soft but sturdy. The mesh sleeves make escaping impossible, but my daughter doesn’t seem to mind at all. I think having a little mobility is exactly what she wanted. Bedtime is no longer a struggle. The only downside was that shipping isn’t as fast as they claim. It didn’t ship the next business day, the label was just printed then. It took so long to receive that my daughter won’t get as much use out of it as I’d hoped, something that I’ll keep in mind when I order her next one.
Ashley K.
I love the zen one and so does my 3 month old, but it already ripped near the zipper arms and at the zipper near the feet after 1 week of use! :(
Andrea B.
It came with a noticeable hole near the arms. Did not return as I was desperate for baby to sleep well and did not want to wait but it was disappointing as the branding is so well known and the reviews seem so good

This has helped my sons sleep, and is my favorite sack BUT I find it to be short, I wish so badly this was a little longer.
Kayla P.
So far loving this! My little man absolutely hates his arms being swaddled at his side. He was always naturally sleeping with his arms by his face. So when I saw this sack allowed his arms to be by his face I knew we had to give it a try. He is 6 weeks old and we've been using it for a week so far. The first night he slept 7.5 hours. He now averages 5.5 to 6 hours a night which has been amazing for Mom and Dad. Hoping this trend continues and will definitely get the next size up!
Jessica O.
Luca loves his new swaddle. He is only 10 weeks old but prefers to keep his hands up when sleeping so this is perfect for him. This is the Cadillac of swaddles!
Kameron B.
The way this swaddle fits my little one- well let’s just say it’s magic. He’s so cozy and comfy in it. The lightly weighted portion really makes a difference.
Maria S.
Ordered in 3-6 month and it seemed kind of small. My daughter is about to be 3 months and looks like she’s almost going to outgrow it. She is a little bit bigger for her age but I expect it to last as a wearable blanket since we were trying to transition out of swaddles. I’ve used it maybe 3 times but it’s been too cold to use only this on her at night so we haven’t used it in a few weeks.
Torrie G.
I really wanted this sleep sack to work and gave it about a month. Unfortunately, my son breaks free of the swaddle band and his little hands are sticking out of the neck opening when he wakes up 2-3 hours later. His arms are also to long to comfortably stay in the sleeves by his face. There have only been a handful of nights that he slept longer than 4 hours in one shot.
Brittany S.
Would recommend to anyone with an infant! I love it and my 4 month old loves it!
Angela W.
We loved the Zen sleep sack! We got it after transitioning out of the swaddle at 8 weeks and love the arms up option. At 11 weeks, we removed the arms and now are in the sleep sack. It was so nice that this sack can be a swaddle, transitional, and traditional sack! The weighted part is the perfect amount and mimics a parents touch well. Not too heavy at all. Looking forward to the 6 month+ size as my tall little one is outgrowing it quickly! Worth the price and good quality and holds up well in the washer and dryer.
Brittany L.
The zen one is absolutely everything it promises. After a few nights, our 3 week old newborn was sleeping so sound in his bassinet that we had a few nights where he slept for over 4 hours at a time. It is an immediate change in his demeanor when we put it on him each night. It even helped calm him when we stayed away from home at the grandparents. We are so grateful and won't go anywhere without it. Thank you!
Kendall H.
This has helped so much! 5 hours of peaceful sleep!

I am so sad I discovered it when my baby was about 8 weeks! I would’ve loved to have this with him as a newborn. It’s super simple and easy to use. With the other swaddles he would get to warm and this was perfect for our room temperature. I used it with his hands in at first and then transitioned to having his hands up. Now we have the next size up. Loving this swaddle!
Coralys R.
My little one loves to sleep with his arms up. This is a happy medium, since he is able to move his hands comfortably. He will usually sleep 6 hours straight using this swaddle, I absolutely love it!
Mackenzie J.
I have been telling everyone about this sleep sack. My 8 week old daughter has been averaging 8-9 hours of sleep straight through the night ever since using the sleep sack. Very pleased with this product and will be buying from this company again in the future!
Lauren B.
My son slept so good in this as a newborn that we had to buy the next size! He is being transitioned out of the swaddle all together and being able start the transition with one arm is working wonderfully. I will definitely be buying the zen sack and am contemplating gifting a bundle set to one of my expecting girlfriends! These sleep sacks are the best.
Bethany N.
Our daughter sleeps so well with her Nested Bean sleep sack. Can’t imagine life without it.
Jessica P.
We ordered these for when our baby comes in March so we haven’t tried it yet however it seems like good quality! My only complaint is that upon opening the package the swaddle smelled HORRIBLE, like manure almost. We washed it and the smell went away but we ordered more than one and the other didn’t have the same problem.

Bought the zen sleep sack for my grandson to help him sleep through the night. Best purchase ever he loves the egg on his chest and falls asleep quickly, stays asleep longer.

Son was almost 9lbs when born so I purchased the 0-3 mo but I personally feel like it’s a little extra snug? But maybe that’s shay it’s supposed to feel like? Just seems like he’d outgrow it pretty quickly since he was born at 21 in also. Overall I do like the nested bean and would recommend if you are looking for a swaddle to help your baby sleep.
Alicia M.
Highly recommend this product! We could immediately tell a difference in how well our little one slept. He would fall asleep more quickly and stay asleep longer. Better sleeping baby = more rested mama. Thank you Nested Bean!!
Sal V.
Love our nest bean swaddle! Used the original swaddle for my first daughter and she loved it as well!
Michelle S.
My son never liked to be swaddled and would always manage to break out of it to have his arms by his face. This swaddle was a life saver! The light weight added comfort for him as well. Everyone needs this swaddle. I just ordered this one since he almost is outgrowing his newborn one!
Jen M.
Love it, she sleeps so well
kelsey y.
I was worried about transitioning from a full swaddle to a sleep sack. This does the job. She loves having her hands free to move around instead of down by her sides. We love this!!!
Sanna A.
Best swaddle!
Ellen L.
We really like this swaddle but it runs really small in my opinion! My son is 9lbs and I feel like it's super tight to zip up.
Teresa S.
Our baby is too big for the swaddles. I bought two different sizes, just didn’t fit right.
Daria P.
They are really soft but my baby doesn't like to sleep in it. Also because the baby had 4200g when he was born the 0-3 months is to small for him.
Tiffany L.
I went by the month range and should have gone by weight. My little guy is about to outgrow his newborn size after barely using it.
Nevena R.
It is great thing that made my boy sleep 7 hours when he was 8 weeks. But unfortunately, he only wear this size for 5 days and becomes small
david c.
The fit was too tight for my one month old
Tricia M.
Really like this sleep sack! The arms up while still feeling swaddled got us through the bassinet to crib transition and beginning of sleep training. We did have to take the arms off at 7 weeks because she was getting so close to rolling over and that just made me nervous. I also don’t agree with the weight sizing - I had to go up to 3-6 months when she was 12lbs even though the 0-3 month size is supposed to reach 13lbs. That’s my only complaint! Love that it’s breathable cotton and the design. Will probably get more as she grows!
Candace s.
He immediately calmed and went to sleep when I put it on him!
Maddy C.
The best purchase I have ever made for my baby! The first time he wore it he slept 5 hours without waking up, which was a huge win for mom and dad!! Definitely recommend this for your little one!
Tejal S.
My son has been sleeping better with this swaddle. I highly recommend!
Leah J.
I love this weighted sleep sack so much. I noticed that the webbed net arms really help instead of having the arms wrapped against her body. She tends to get better rest this
way! So thankful fir this and would definitely recommend ☺️
Taylor F.
Loved it! Baby went from crying 4 hours at night to sleeping 7 hours straight in 3 days.
Angelica S.
Amazing customer service and an amazing product! Have been telling everyone I know this product is amazing!!
Jessica A.
My son born 5lbs after 3 weeks old hated to be swaddled. So was recommend to try this. But was was not 7lbs until he was just over 5weeks. So I finally tried this product. Great quality, but my son still did not like the arm constraint so I removed, but he still did not like it. I waited til he was 9lbs then tried without the arms again. I do see it helps a bit. Perhaps if your child is born over 7lbs and you use the product starting in hospital or at least immediately at home you may get better results.
Tabitha S.
Great product
Melodie C.
Once our 6-week old switched to this swaddle, he started consistently giving us 3-4 hours at the beginning of the night. The only issue I have is that his arms don’t fit in the part intended for the hands-up position — maybe he has long forearms? Hoping this lasts a little longer so he can transition to arms out before we have to purchase the next size up.
Ella M.
I’m so happy I discovered Nested Bean! I was struggling with getting my little one down for naps. I’d get him rocked to sleep and then when I went to lay him in his crib he’d jolt awake. With this new swaddle I don’t have nearly as many issues with this as I did before using it. The weight really helps with transitioning him onto his bed. Even if he stirs, he’s much easier to get back to sleep because of the weight of the swaddle. Recommend to anyone who has this issue!
Angie J.
Never used the swaddle for the arms but really like the weight of it. Very soft bamboo
Brandi M.
Love it. It’s my son’s favorite swaddle. We just sized up to the 3-6m one.
Kelsey S.
Perfect transition from arms down swaddles to this before going into a sleep sack!
Shalan J.
Helped baby stay asleep .
Kayla B.
The same night we used it our little man almost immediately stopped fussing and went to sleep. Getting a good 6 hours through the night! We all love this and so happy we went with this swaddle!
Kyleigh M.
Love this sleep sack/swaddle. While my 1 month old still wakes up in it, he seems to have an easier time calming back down. The arm pieces were a little small for him, but his arms are pretty long. I don't know if I'm going to go with a sleep sack or another zen swaddle for the next size. I think it's worth a try and worth the investment.
Tiffany R.
Love the nested bean swaddles. My babies have always slept the best in these. However, I bought the wrong size and immediately tried to contact customer support and change it and just kept getting the run around of emails and ended up receiving the wrong size. Otherwise, love nested bean and will continue to recommend these swaddles and sleep sacks to all my friends
Athena H.
My two week old didn't like her arms swaddled. We tried the Nested Bean Zen One and I think she loves it. She only wakes once a night!
Lauren B.
The best thing for helping my little one stay asleep!
Renee R.
Love this perfect for transiting from swaddle to sleep sack buy my only complaint is when I washed it the first time I got two holes on the seams
Gina M.
I LOVE this swaddle, it’s the best out there, BUT…I’ve bought two of them and both came unstitched in the front where the legs go. Exact same area in both swaddles. For the price of these I don’t expect to have to sew them myself.
Emma M.
I don't know what I would do without this swaddle! Our baby flails and wiggled free from every "regular" swaddle no matter how good someone swaddled him! The nested bean saved our baby and his mama and daddy from sleeplessness! Whoever created this was a genius.
Juree C.
It’s nice! The baby likes it, but I did not get the same result as others, he didn’t magically sleep through the night the first night he wore it. BUT it is such soft material, the light weighted feel is so nice, and I do believe baby boy sleeps comfortably in it. I would purchase again.
Amanda I.
Best thing ever invented. This is the second one we’ve purchased because he out grew the first. We use it for naps and it is an essential part of our bedtime routine. My little guy went from walking every two hours to nurse to sleeping 4-5 hour stretches at night at only 2 months old since wearing the zen one
Kayla K.
BUY this if you enjoy sleep. I wish I purchased this even sooner. My daughter loves it. I’ve already purchased one in the next size up, and I plan on getting more so we never go a night without a clean one available to use. She never liked being swaddled in a blanket, so I was shocked that she loved this so much. She sleeps so soundly and comfortably. She used to wake up every hour…every night! Now, she can sleep up to 5hrs at a time and only wake to eat! Truly the best purchase ever!!!
Anna C.
These are really nice quality. I was hoping to use this to transition my son out of a swaddle since he loves to have his hands up toward his face- unfortunately his arms aren’t even close to fitting in the “wing” area. I just zipped them off and he has been tolerating a 7-8 hour stretch at nighttime between feedings at 7 weeks old. I think this product needs a bit of an adjustment but overall we still love the nested bean sacks.
Jackie H.
I JUST got this in the mail today, he's had two naps with this and already there's such a difference! He always manages to get his arms out of my swaddles, no matter how tight and loves to sleep with his arms up by his head. But he startles himself awake A LOT. Those little wings are freaking perfect for the way he likes to sleep! They keep his arms from flailing and waking him up but allow him to sleep in the position he prefers. Now I can rest and get naps in myself! Ugh!! Love, Love, LOVE IT! ❤
Lauren G.
I tell EVERYONE about this! It’s so versatile and transitional in that you can do arms in, one arm out, or both arms out. The weighted sacks must be in the perfect places for comfort and security because my little one’s sleep has improved tremendously with this purchase!
Megan D.
Love this sleep sack! Just wish they made them in a bigger size. My 3+ month old is long. Her legs are about to push through the bottom and her arms are too tight in the alotted space now.
Katelyn P.
It’s nice you can swaddle arms however you want
Tejal S.
It keeps our 2 month old cozy and I believe he feels more secure so he sleeps well at night, we use it for his day time naps! I like the mesh flaps as he likes to keep his hands near his face :)
Kassidy K.
Best swaddle hands down! You will not waste your money! Just buy it now!
Stephanie M.
Customer service is absolutely fantastic. We originally bought the 0-3 month based on our babies weight, but she ended up being too tall & needed a size up. They shipped out the next size up right away which was super helpful. The weight in the product was still a proper ratio for her based on our research, so we felt ok to use it for supervised sleep at first, and have now been using it at night.
The removable mesh sleeves have really helped us with transitioning her out of the swaddle stage, and she just slept a 9 hour stretch after about a week. She still has difficulty connecting her sleep cycles when napping, but we are very grateful she is starting to turn around her night time sleep.
Was very nervous about using a weighted product, but after doing some research, we felt that this particular product was safe. Also washes well & the material is really nice. We are hoping we have continued success with the Zen One & can successfully buy the Zen Sack when she is ready!
Samantha W.
It was cute and well put together. My daughter was not a fan. The swaddle would twist and bunch really bad around her neck. It's also really small. My baby is tiny and this swaddle clung to her and she was 7 lbs.
Bailey N.
I loved this product at first! My son was able to sleep for a longer periods during the night.
After three washes the stitching around the chick, that forms the weighted center, came undone. The swaddle is lumpy and not weighted properly anymore. Really disappointed considering how expensive the swaddle is you'd think it would hold up better.
K p.
Nested bean is too small for my four month old son . I ordered 3-6 month for him but still too small . He kind of likes it but I prefer it to be a little bigger.
Chelsea G.
This has helped my little babe sleep through the night with no interruptions! The other swaddles don’t even compare!
Ana A.
The only draw back is that the arm slots are slightly too small for my son. I wish he had more room. His wrist are flexed in the slots.
Marie T.
My newborn baby loves her swaddle. She is now sleeping through the night.
Trinity G.
I used to have to have my hand on my daughters chest for her to fall asleep. Thanks to the weight, she falls asleep without my hand!
Katie D.
This product is amazing. It calms my granddaughter down as soon as she gets in it!!!
Kandice F.
My little loves sleeping with his nested bean! We went from being up every two hours to 4-5 hour intervals!
Leah R.
Because my daughter likes to sleep with her arms out and up and to suck on her hands etc I thought this would be a good alternative as it allows them to still get their hands to their mouths etc..
However, she doesn't sleep any better than with any other wrap, feels like an expensive alternative at this point. Also, the bottom of this doesn't unzip in a way that you wouldn't wake them for a diaper change if needed because you still have to pull their legs out.
The material is nice and thick tho which is nice.
Petie R.
Worked the first night- this is a big deal because up till now, our little one would ONLY sleep nights on my chest.
Lifesaver!
Jessica B.
My daughter liked being swaddled for approximately the first week of her life. After that, she actively started attempting to escape them (and usually succeeded), screamed while we swaddled her, and had to be consoled afterwards. We wanted to stop swaddling, but her startle reflex doesn’t make that feasible. Once she learned to free her arms from the Halo swaddle, I looked into the Nested Bean on the suggestion of a friend of a friend. The Zen One is magic! It’s easy to use and the material is soft but sturdy. The mesh sleeves make escaping impossible, but my daughter doesn’t seem to mind at all. I think having a little mobility is exactly what she wanted. Bedtime is no longer a struggle. The only downside was that shipping isn’t as fast as they claim. It didn’t ship the next business day, the label was just printed then. It took so long to receive that my daughter won’t get as much use out of it as I’d hoped, something that I’ll keep in mind when I order her next one.
Ashley K.
I love the zen one and so does my 3 month old, but it already ripped near the zipper arms and at the zipper near the feet after 1 week of use! :(
Andrea B.
It came with a noticeable hole near the arms. Did not return as I was desperate for baby to sleep well and did not want to wait but it was disappointing as the branding is so well known and the reviews seem so good

This has helped my sons sleep, and is my favorite sack BUT I find it to be short, I wish so badly this was a little longer.
Kayla P.
So far loving this! My little man absolutely hates his arms being swaddled at his side. He was always naturally sleeping with his arms by his face. So when I saw this sack allowed his arms to be by his face I knew we had to give it a try. He is 6 weeks old and we've been using it for a week so far. The first night he slept 7.5 hours. He now averages 5.5 to 6 hours a night which has been amazing for Mom and Dad. Hoping this trend continues and will definitely get the next size up!
Jessica O.
Luca loves his new swaddle. He is only 10 weeks old but prefers to keep his hands up when sleeping so this is perfect for him. This is the Cadillac of swaddles!
Kameron B.
The way this swaddle fits my little one- well let’s just say it’s magic. He’s so cozy and comfy in it. The lightly weighted portion really makes a difference.
Maria S.
Ordered in 3-6 month and it seemed kind of small. My daughter is about to be 3 months and looks like she’s almost going to outgrow it. She is a little bit bigger for her age but I expect it to last as a wearable blanket since we were trying to transition out of swaddles. I’ve used it maybe 3 times but it’s been too cold to use only this on her at night so we haven’t used it in a few weeks.
Torrie G.
I really wanted this sleep sack to work and gave it about a month. Unfortunately, my son breaks free of the swaddle band and his little hands are sticking out of the neck opening when he wakes up 2-3 hours later. His arms are also to long to comfortably stay in the sleeves by his face. There have only been a handful of nights that he slept longer than 4 hours in one shot.
Brittany S.
Would recommend to anyone with an infant! I love it and my 4 month old loves it!
Angela W.
We loved the Zen sleep sack! We got it after transitioning out of the swaddle at 8 weeks and love the arms up option. At 11 weeks, we removed the arms and now are in the sleep sack. It was so nice that this sack can be a swaddle, transitional, and traditional sack! The weighted part is the perfect amount and mimics a parents touch well. Not too heavy at all. Looking forward to the 6 month+ size as my tall little one is outgrowing it quickly! Worth the price and good quality and holds up well in the washer and dryer.
Brittany L.
The zen one is absolutely everything it promises. After a few nights, our 3 week old newborn was sleeping so sound in his bassinet that we had a few nights where he slept for over 4 hours at a time. It is an immediate change in his demeanor when we put it on him each night. It even helped calm him when we stayed away from home at the grandparents. We are so grateful and won't go anywhere without it. Thank you!
Kendall H.
This has helped so much! 5 hours of peaceful sleep!
Frequently asked questions
-
How much weight is in the Zen One?
The Zen One™ swaddle includes 3 gently weighted sections, two on the sides and a self-contained Cuddle Pad™ in the center. The weighted areas of the product are 42 grams (30 gm in center, 6 gm on each side) for the NB size and 60 grams (40 gm in center, 10 gm on each side) for the Small size. Our products are designed to adhere to American Academy of Pediatrics (AAP) physiotherapy standards and Guidelines for Safe Sleep, which recommends a weight-to-body ratio of 1:10. Our product is safely weighted in key areas as opposed to all-weighted sleepwear or weighted blankets, which the AAP has deemed unsafe for infants.
-
How can the Zen One™ be used in different ways?
The Zen One adapts to your baby’s unique sleep style at every stage. For newborns, a secure band holds arms down to prevent the startle reflex. For active sleepers, breathable mesh sleeves keep arms in but visible, so babies can self-soothe during sleep.
-
When should I transition my baby out of a swaddle?
Once your baby starts showing signs of rolling over, it's time to begin the transition from a swaddle to a sleep sack. The Zen One can adapt to become a sleep sack by zipping off the removable mesh sleeves. If your baby is starting to outgrow the Zen One, we suggest upgrading to our gently weighted Zen Sack™.
The Zen One™, the only swaddle you'll ever need.
Make transitions easy
Gently weighted to help babies fall asleep faster and sleep longer, the Zen One easily adapts to every sleep style, from birth to 6 months.
Keep rolling babies safe
The Zen One has removable sleeves, making it a safe option for babies who are starting to roll.
Help active sleepers self soothe
For active sleepers who prefer arms-free, the Zen One has quick-drying mesh sleeves to promote self-soothing for thumb suckers. The Zen One has a secure inner band that holds your baby’s arms tight to prevent wake-ups from startle reflex.
