Sulema A.
Love these sleep sacks! My baby sleeps so much better having his sleep sack on - the weight really helps him feel like he’s being held . Highly recommend!!!
Kristian V.
My baby has loved it so far! She's in that middle stage of needing to be swaddled due to reflex but also needs her arms not fully constricted, so the Zen sack is perfect!
Jennifer S.
We love this sleep sack! It was such a smooth transition from the medium size to the large. I was worried about the weights in the chest being different, but our son did not skip a beat! He sleeps so well in these. He is a stomach sleeper and can maneuver very easily!
Jessica F.
Our daughter has been struggling with sleep since she has come home. She was in the NICU for 19 days and the transition to sleeping at home was very hard on her. She would only sleep a few hours at night and then be extremely overtired- crying for hours. As well as, sleeping for 10 minute durations at a time during the day. On the very first night of using the nestedbean our daughter slept for 7 hours straight! We are trilled with the nestedbean and our little girl is so much more happier!
Phyu T.
I dont usually spend time to write reviews but I want to share my experience for all sleep deprived parents out there. Before nested bean, my baby (5.5 months old) , he slept all night long with waking up like 4 times in between. He sleeps in his own crib but sometimes unable to put him down and needed to co sleep if necessary. We were so desperate and bought nested bean to give a try. On the first night , he slept 11 hours straight, and I was freaking out (checking hourly as he is still breathing or not) We used nested bean for 12 nights so far, he slept through the night half of the time (10-11 hours straight), some nights he woke up for the feed (6 hrs straight and then 4 hrs) and could be one or two bad nights (failed self soothe around 5am and need help with sleep). This is much better than it was before, buying nested bean sleep sack is a game changer for us.
ELIZABETH S.
Love these so much! The fabric is super soft, keeps baby warm and cool.
eliza m.
Will definitely purchase the swaddle when I have another baby.. my daughter loves it
Makenzie S.
We love our sleep sacks! We transitioned to these from swaddles and the first night the babies both slept for a 4 hour stretch which is great for them! I like that it’s breathable so they don’t get too hot and the weight is only on their chest so it feels like a hand providing comfort, but still allows them to move.
Terry G.
Got for my great granddaughter and she is in heaven wearing her new swaddle. Thank you
Tiffany W.
The sleep sack is great for my newborn because he doesn't like having his arms swaddled. I think it could be better if the sleeves were long, rather than the inch or so.
It also rides up as my son moves around, so periodically, I have to pull down the front or the back because its ridden up so much.
It's also difficult to burp my son while he's wearing this, so I have to remove it for midnight feedings/burnings.
Be does sleep well in it, so that's a plus.
Allison H.
Beautiful
Maggie T.
Silky and soft material, easy to wear. Baby seems cozy wearing it.
Diana L.
Is very good quality and also very cute! But my baby just don’t like every time that she used she will cry for hours
Sheldon B.
The swaddle still doesn’t help my child sleep at night; however, it’s great quality.
Daisy B.
I was eager to try this out in hopes that it would help out my son sleep for longer stretches at night but it doesn’t seem to make a difference. His longest stretch is about 4 hours every night and it was the same before making this purchase. I wish I could say it is working out for us but it’s not.
Taylor C.
I LOVE THIS SLEEP SACK! I like how it’s not fully weighted. It feels cooler. My 18 month old was going through a sleep regression when we got this and sure enough it helped him start sleeping through the night again
Kristie D.
This is my second child, her sister was a notorious BAD sleeper. We were so hopeful and so dedicated to making sure the second became a “good sleeper” …. But alas, within a week of being home things were going off track. We even were co-sleeping, which we SWORE we would never do again. It took hours to get her down.
Then I got the Zen One sleep sack, and it literally was like MAGIC. I am not one for reviewing, I’m not being paid, I just want to share so maybe I can help another desperate parent! This sleep sack is, as many others have said, a GAME CHANGER. Literally night one she was in her pack and play sleeping soundly. We have been using it for one week now and last night my 8 week old daughter slept ALL NIGHT (8:30 - 5:25). I highly, highly recommend this sleep sack!!!!
Hawo A.
Very nice
Yumaira M.
Very nice color and quality
Desiree C.
We love our Nested Bean Zen sleep sack!! We use it every night. He slept thru the night for the first time on only our second night using it!! It has helped our sleep schedule and in turn helped me transition back into work..
Danielle G.
I love this sleep sack! It’s my second one and my newest grandson loves it along with my daycare littles! It’s got the perfect amount of weight on the chest and when you zip it up, it helps them to feel like they are being “hugged”! Thank you for this product and allowing babies to sleep better and longer on their own!
Gabrielle O.
My 2 month old would only sleep if he was on my chest since the day he was born. I needed a break and for him to be able to get rest in his bassinet. I was skeptical of the Zen Sack but I gave it a try and first night we used it everyone was able to catch up on sleep!!! I’m so happy with our purchase and recommend this product if you have a fussy clingy baby
Emily M.
We love nested bean! The sleep sack is very soft, durable and easy to get ok and off. We have them at home as well as daycare
Rilee H.
I was looking to upgrade my sons sleep sack before we started sleep training. I came across an article that was talking about this sleep sack so I went ahead and tried it out. We love it and our son loves it! The gentle weight on his chest has helped him so much. He’s a much happier baby!

We love our Nested Bean sleep sack! My little guy has used their swaddles and now the sleep sack and has always slept amazing! I recommend their products to all my first time mama friends and have even given a few away for baby shower gifts.
Jennifer J.
Love how they give my child safe feeling . Like she right next to me
Amanda G.
My baby loves these sleep sacks
Catherine M.
My baby is finally sleeping without being held and he’s sleeping through the night! Thank you Nested Bean!
Kristen S.
Can’t really tell any magical powers with this. I have zero differences I can tell between this sleep sack and a normal one
Amanda L.
We loved it so much we bought a second one! Our baby loves the weighted comfort and it’s easy to put on and off.
Kaity V.
I love it!
Lyndsi T.
I’ve been using these sleep sacs since my little one was around 3 months old. Unlike another sleep sac I was given by a friend, this one doesn’t have the weight all over which made babe super uncomfortable and wake a lot, this one has just enough! I started with the 1.0 tog for the cooler months and when baby turned 9 months we switched to the 0.5 tog for the warmer months. We love nested bean and highly recommend it for its comfort, overall style and affordability!
Stephanie L.
Have been using nested bean for 3 years now since my oldest was a newborn. Love them!
Carly H.
We absolutely love the Zen sack! Our daughter is 6 months old but very very tall so I wanted a sleep sack that she wouldn’t outgrow right away. This exceeded our expectations! The adjustable straps and extra room by her feet will help her use this for many months. Most importantly, she sleeps great in it!
Alyssa B.
Before nested bean, our 2 month old (at the time) would only sleep in 2 hour intervals. I was skeptical about the lightly weighted sleep sack because how could this make THAT big of a difference. We were told she was colicky, just not a great sleeper, switch up her food, etc.. With this sleep sack, ON THE FIRST NIGHT WEARING IT MIND YOU, our 2 month old slept from 10:30 pm-7:30 am, I woke up, fed her and changed her and she slept AGAIN from 8 am-10:30am. THANK YOU NESTED BEAN! This mama is finally catching up on some MUCH NEEDED SLEEP!!!!!!!!!!!!!!!
Amber J.
favorite thing ever. been using since my daughter was a newborn i wish they went to even longer sizes bc she’s long legged. but still highly recommended ⭐️⭐️⭐️⭐️⭐️
Beverly W.
I got this for my granddaughter to help her sleep better at night and it definitely works. She is a very happy baby and mommy is getting some sleep now. Thank you Nested Bean!
Priscilla W.
It’s great
MARISOL R.
I had super high hopes for this! I was eager to get some more sleeping time for baby girl and I but unfortunately this was not the answer, she still struggles to fall asleep and wakes a lot during the night. I used it for about 2 weeks now and I have officially given up on it
Lauren K.
I really liked this sleep sack but it didn't help my baby sleep at all. It's also really thin so great for summer but you would need something thicker for winter. I'm going to keep trying but so far I have had no luck with it.
E S.
Does not work. On night 2, noticing no change. The “weighted” part is barely weighted. To me this is a normal sleep sack.
Edana R.
Nice and soft. Didn't help out little one's sleeping at all sadly (I was so hopeful!), but it is a nice comfortable sleep sack - easy to put on and take off and nice material!
Jeri S.
I was back and forth on this sleep sack, and I’m so glad I purchased this one! My son was swaddled from birth to 4 months. He kept breaking out of his swaddle so we knew it was time to get a sleep sack so he could sleep with his arms out. We also were wanting to start sleep training as well. We did both and they were a rough few nights of arms out and sleep training, but after night 3, he sleeps so good! It’s so easy to use! The only downfall, it takes forever to dry when you dry it on delicates. I made the mistake of washing it an hour before bed. Won’t do that again. I just need to purchase another one!
Patricia K.
We used nested bean for our first child, now our second. The weight on the front helps him self better. I love these sleep sacks.
Michael W.
Baby girl loves it!
Brooke K.
Such a great sleep sack!!! My son loves the nested bean sleep sack and sleeps 12 hours straight in them. Great quality, great price, absolutely adorable - get 2!!
Lauren P.
This sleep sack has been life changing! My baby used to only sleep if he was being held. After a month of consistently using this sleep sack for naps and nighttime, he is taking all his naps in his crib and doing longer stretches at night! I’m going to order another right now so we have an extra when this one needs to be washed! Best purchase ever!
Megan H.
We love NB sleep sacks! Our daughter is a tummy sleeper and having the weight on her back keeps her cozy! Wash and wear great.
Dara S.
Helps baby sleep for longer stretches during the night and worked by night 2!
Kimberly P.
My son was waking up every hour and I was getting no sleep. I got this and the first night he slept 2 hours. That wasn’t impressive enough BUT I decided to sleep train with this and I heard all the horror stories about sleep training but on the first night of sleep training with this sleep sack my son only cried for 2 minutes and slept over 10 hours. I have to give credit to the Nested Bean Zen Sack.
Connor C P.
This photo was the first time in 2 months my child sleep in her crib. She is 4 months old and I cannot stress the amount of magic this sleep sack has. Remember this doesn’t fix babies from waking in the night, but it greatly helps! She went from waking up every time I put her in her crib… to putting her in her crib in the nested bean to waking up 1-2 times a night. I haven’t slept without a child in my arms for two months. This is a heaven sent item for parents and our babies!
Sarah B.
The sack really didn't make a difference in our 6 month olds sleep schedule. She was still waking up every few hours. We had to let her cry it out. The sleep sack is soft for baby to sleep in but it didn't do what advertised.
Roberto C.
Great!
Stephanie K.
I noticed the first night of my Son wearing it that he seemed to sleep much better. I like the weighted chicken on the chest because it's like we're still there holding him.
Molly B.
We love these sleep sacks. They provide just a little pressure like a gentle press of our hand would to soothe him. It is easy to zip either way if you have to do a tired diaper change in the middle of the night. The quality is fantastic and I believe it will last on him for much of the rest of his first year and then will hold up for any more kids to come.
Audrey D.
Our baby is 7 weeks old and would only sleep in the swing until we got the nested bean sleep sack. The first night he had it, he finally fell asleep in his crib for the first time ever and slept in it all night! 10/10 recommend and is a MUST HAVE in our house and will be for our future children!!
Alexis J.
This has been a game changer for our 8 month old. Wish I purchased sooner!
Katherine M.
My son loves the nested bean! I really like that you can put it on the front and the back! I sized up because he is on the taller side and I’d rather him have the extra space!
Alisha A.
It helps my baby sleep on her back.
Eric G.
Our daughter absolutely LOVES her Nested Bean sleep sack. We had to buy a second one right away because she took to the first one so quickly. She falls asleep so quickly in it and loves putting her hands on the weighted beans while she sleeps.
Karen F.
Love it! My grandson sleeps so much better…and longer now!!
Alison W.
We love our nested bean! Have used it for both our littles!
Rachel S.
We love our sleep sack! It’s so comfy and makes us happy
Jillyn K.
My 2 month old used to be a terror to put down in the middle of the night. He hated his crib. That changed the first day we had the sleep sack. He is now taking 3 hour naps during the day and sleeps almost through the whole night!
Rachel D.
This sleep sac has helped my son sleep a little longer by himself. But I can’t say it’s a good as they claim even after wearing it everyday. We will continue to use it.
Sherri R.
The perfect sleep sack! Keeps kids calm and comfortable
Joshua K.
For some reason I thought this one was black and it is more blue for sure. Also after washing it once this color collects a lot of lint and makes it look worn out. Kind of bummed about that but my daughter does love these sleep sacs
Stephanie S.
Such a soft but warm material for my baby. She sleeps so cozy and comfortable in the Nested Bean sleep sack!
Mackenzie H.
Love our Nested Bean sleep sacks! Helps my daughter sleep through the night and is soft, comfortable. It shipped super fast, too!
Karly M.
YES! So good
Laila A.
A fantastic sleep sack. My LO sleeps soundly. I almost wish they had adult sized ones haha.
Kayli M.
Our boy LOVES his nested bean sleep sack! He used to LOVE being swaddled but then decided that he still loved it but without his arms being swaddled but I wanted to just give this sleep sack a try & it was an instant hit. Definitely wish I would've bought 2 though so I always had one ready if the other got spit on or something! Will be purchasing another asap!
KYLIE K.
My baby lives this thing! Easy transition for her
Lindsay G.
Our baby outgrew the swaddle but is very active. We bought this in hopes it would help her sleep swaddle free. 3 days in and she slept through the night. Highly recommend.
Lindsay
I ordered my first sleep sack for my daughter when she was a newborn and it did fit nicely. I decided to order another one now that she is 9 months. I got the 0.5 in her age bracket, since summer is approaching and it does get quite warm where I live. My daughter is quite long, in the 95th percentile for height and weight. I feel that the sleep sack is a bit small for her. It does fit her currently, but I feel like she will outgrow it by next month.
Kayla H.
Better sleep was on the way! We love this sleep sac. We have tried so many but now that he is starting to roll he doesn't care much for them. This one keeps him warm when the AC is on but cool enough to sleep well. We love that we can flip it around to provide comfort in different ways.
Jessica F.
Hasn’t helped my baby with sleeping, but keeps him warm.
Johanna L.
Great material, and looks great, but did nothing for sleep. It’s hopeless!
Jennifer F.
Love the pattern!
Jennifer F.
These sleep sacks are the best!
Kate R.
my little one loves her zen sack!
Colleen F.
We have a Zen Sack Classic and a Zen Sack Quilted and despite being the same size they are significantly different. The Zen Sack Classic is 3 inches shorter than the same size of the Zen Sack Quilted. We love the product just wish there was some consistency in the sizing. The classic was a waste of money for us since our son never fit in it despite still fitting comfortably in the quilted version.
Celia S.
My 16 month old had a sleep regression. I ordered baby melatonin and this sleep sack. Both helped. I tossed all the other sleep sacks and only use this one. My daughter sleeps on her tummy so I put the weighted part on her back.
Karen B.
Love this product. Our son is a great sleeper but he was starting to roll over in the Magic Merlin suit. We switched to the Nested Bean after a friend recommended it. Took one night for him to get the hang of it. The suit is so cute, the fabric soft.
My only question is - if he rolls on to his stomach, will the weighted bean that’s sewn into the chest area be uncomfortable, preventing him from sleeping in that position?
Hannah S.
This is our third nested bean sleep sack! We really like them, but we’ve never tried anything else so I can’t compare it to anything else.
Lisa R.
Bought as a gift
Vanessa D.
Our newborn hates to be restricted and loves having her hands and arms free as she sleeps now 7+ hours through the night!
Kaitlin D.
Love the material this is made of! I have a super hot natured baby and this is perfect for him.
Courtney W.
Super soft & my daughter is sleeping through the night!
Jasmine N.
It’s okay, I got it when my son was 6 months and he did struggle at first to sleep in swaddled and not sure if the weighted area helped much, but he is sleeping better through the day and night, not fully sleeping through the night still. Not sure if the sack is helping in any way but definitely was worth a try.
Melissa W.
My tiny human falls asleep in less than 10 minutes with the Nested Bean Zen Sack! He sleeps longer stretches and is knocking that 4 month sleep regression out of the park!
Katie K.
We liked this sack for our daughter who is 2 and a half months now. She never really liked swaddles, and this would keep her legs covered without constricting her. My only criticism is that I feel like the shoulder straps are too snug on her. Especially for a 0-6 month fit. Had I known this, I probably would have gotten a size up. So now we only use it occasionally.
Melissa W.
I’ve bought a lot of sleep sacks between 2 babies and this one is fine. I’m not a big fan of the shoulder snaps as they allow for minimal adjustment but otherwise are hard to mess with at night (if you want to fully remove it for a feeding) and they add some bulk.
Adele C.
I absolutely love this zen sack! My daughter has slept through the night since using this when she was around 4 months old. I would highly recommend giving it a shot. I know that every baby is different, but this may be the missing piece for you to get your baby to sleep through the night like it was for me!
Paola H.
It really works!! My baby boy is about to be 4 months next week and he has been slepping 6 / 7 hours at night I got a size 6-15 months and I am glad I did (he is a tall baby)
The sleep sack is super soft and cute!
olivia s.
I can’t say that it’s made a difference in his sleep. Will keep trying
Mary T.
Exactly what I wanted! We have used the nested bean sleep sacks for a while and love them! Just needed a new one for my new little guy.
Amber D.
The material of this sleep sack is so smooth. It doesn’t get too hot for my baby and keeps him comfy all night!! Will definitely be buying this as gifts and in bigger sizes!
Philip M.
Our little guy has used one of these essentially since birth. He grew out of the old one and seems to be liking this bigger size so far. Would recommend.

I started with the 1.0 tog for the cooler months and when baby turned 9 months we switched to the 0.5 tog for the warmer months. We love nested bean and highly recommend it for its comfort, overall style and affordability!

Have been using nested bean for 3 years now since my oldest was a newborn. Love them!

We absolutely love the Zen sack! Our daughter is 6 months old but very very tall so I wanted a sleep sack that she wouldn’t outgrow right away. This exceeded our expectations! The adjustable straps and extra room by her feet will help her use this for many months. Most importantly, she sleeps great in it!

Before nested bean, our 2 month old (at the time) would only sleep in 2 hour intervals. I was skeptical about the lightly weighted sleep sack because how could this make THAT big of a difference. We were told she was colicky, just not a great sleeper, switch up her food, etc.. With this sleep sack, ON THE FIRST NIGHT WEARING IT MIND YOU, our 2 month old slept from 10:30 pm-7:30 am, I woke up, fed her and changed her and she slept AGAIN from 8 am-10:30am. THANK YOU NESTED BEAN! This mama is finally catching up on some MUCH NEEDED SLEEP!!!!!!!!!!!!!!!

favorite thing ever. been using since my daughter was a newborn i wish they went to even longer sizes bc she’s long legged. but still highly recommended ⭐️⭐️⭐️⭐️⭐️

I got this for my granddaughter to help her sleep better at night and it definitely works. She is a very happy baby and mommy is getting some sleep now. Thank you Nested Bean!
Priscilla W.
It’s great
MARISOL R.
I had super high hopes for this! I was eager to get some more sleeping time for baby girl and I but unfortunately this was not the answer, she still struggles to fall asleep and wakes a lot during the night. I used it for about 2 weeks now and I have officially given up on it
Lauren K.
I really liked this sleep sack but it didn't help my baby sleep at all. It's also really thin so great for summer but you would need something thicker for winter. I'm going to keep trying but so far I have had no luck with it.
E S.
Does not work. On night 2, noticing no change. The “weighted” part is barely weighted. To me this is a normal sleep sack.
Edana R.
Nice and soft. Didn't help out little one's sleeping at all sadly (I was so hopeful!), but it is a nice comfortable sleep sack - easy to put on and take off and nice material!
Jeri S.
I was back and forth on this sleep sack, and I’m so glad I purchased this one! My son was swaddled from birth to 4 months. He kept breaking out of his swaddle so we knew it was time to get a sleep sack so he could sleep with his arms out. We also were wanting to start sleep training as well. We did both and they were a rough few nights of arms out and sleep training, but after night 3, he sleeps so good! It’s so easy to use! The only downfall, it takes forever to dry when you dry it on delicates. I made the mistake of washing it an hour before bed. Won’t do that again. I just need to purchase another one!
Patricia K.
We used nested bean for our first child, now our second. The weight on the front helps him self better. I love these sleep sacks.
Michael W.
Baby girl loves it!
Brooke K.
Such a great sleep sack!!! My son loves the nested bean sleep sack and sleeps 12 hours straight in them. Great quality, great price, absolutely adorable - get 2!!
Lauren P.
This sleep sack has been life changing! My baby used to only sleep if he was being held. After a month of consistently using this sleep sack for naps and nighttime, he is taking all his naps in his crib and doing longer stretches at night! I’m going to order another right now so we have an extra when this one needs to be washed! Best purchase ever!
Megan H.
We love NB sleep sacks! Our daughter is a tummy sleeper and having the weight on her back keeps her cozy! Wash and wear great.
Dara S.
Helps baby sleep for longer stretches during the night and worked by night 2!
Kimberly P.
My son was waking up every hour and I was getting no sleep. I got this and the first night he slept 2 hours. That wasn’t impressive enough BUT I decided to sleep train with this and I heard all the horror stories about sleep training but on the first night of sleep training with this sleep sack my son only cried for 2 minutes and slept over 10 hours. I have to give credit to the Nested Bean Zen Sack.
Connor C P.
This photo was the first time in 2 months my child sleep in her crib. She is 4 months old and I cannot stress the amount of magic this sleep sack has. Remember this doesn’t fix babies from waking in the night, but it greatly helps! She went from waking up every time I put her in her crib… to putting her in her crib in the nested bean to waking up 1-2 times a night. I haven’t slept without a child in my arms for two months. This is a heaven sent item for parents and our babies!
Sarah B.
The sack really didn't make a difference in our 6 month olds sleep schedule. She was still waking up every few hours. We had to let her cry it out. The sleep sack is soft for baby to sleep in but it didn't do what advertised.
Roberto C.
Great!
Stephanie K.
I noticed the first night of my Son wearing it that he seemed to sleep much better. I like the weighted chicken on the chest because it's like we're still there holding him.
Molly B.
We love these sleep sacks. They provide just a little pressure like a gentle press of our hand would to soothe him. It is easy to zip either way if you have to do a tired diaper change in the middle of the night. The quality is fantastic and I believe it will last on him for much of the rest of his first year and then will hold up for any more kids to come.
Audrey D.
Our baby is 7 weeks old and would only sleep in the swing until we got the nested bean sleep sack. The first night he had it, he finally fell asleep in his crib for the first time ever and slept in it all night! 10/10 recommend and is a MUST HAVE in our house and will be for our future children!!
Alexis J.
This has been a game changer for our 8 month old. Wish I purchased sooner!
Katherine M.
My son loves the nested bean! I really like that you can put it on the front and the back! I sized up because he is on the taller side and I’d rather him have the extra space!
Alisha A.
It helps my baby sleep on her back.
Eric G.
Our daughter absolutely LOVES her Nested Bean sleep sack. We had to buy a second one right away because she took to the first one so quickly. She falls asleep so quickly in it and loves putting her hands on the weighted beans while she sleeps.
Karen F.
Love it! My grandson sleeps so much better…and longer now!!
Alison W.
We love our nested bean! Have used it for both our littles!
Rachel S.
We love our sleep sack! It’s so comfy and makes us happy
Jillyn K.
My 2 month old used to be a terror to put down in the middle of the night. He hated his crib. That changed the first day we had the sleep sack. He is now taking 3 hour naps during the day and sleeps almost through the whole night!
Rachel D.
This sleep sac has helped my son sleep a little longer by himself. But I can’t say it’s a good as they claim even after wearing it everyday. We will continue to use it.
Sherri R.
The perfect sleep sack! Keeps kids calm and comfortable
Joshua K.
For some reason I thought this one was black and it is more blue for sure. Also after washing it once this color collects a lot of lint and makes it look worn out. Kind of bummed about that but my daughter does love these sleep sacs
Stephanie S.
Such a soft but warm material for my baby. She sleeps so cozy and comfortable in the Nested Bean sleep sack!
Mackenzie H.
Love our Nested Bean sleep sacks! Helps my daughter sleep through the night and is soft, comfortable. It shipped super fast, too!
Karly M.
YES! So good
Laila A.
A fantastic sleep sack. My LO sleeps soundly. I almost wish they had adult sized ones haha.
Kayli M.
Our boy LOVES his nested bean sleep sack! He used to LOVE being swaddled but then decided that he still loved it but without his arms being swaddled but I wanted to just give this sleep sack a try & it was an instant hit. Definitely wish I would've bought 2 though so I always had one ready if the other got spit on or something! Will be purchasing another asap!
KYLIE K.
My baby lives this thing! Easy transition for her
Lindsay G.
Our baby outgrew the swaddle but is very active. We bought this in hopes it would help her sleep swaddle free. 3 days in and she slept through the night. Highly recommend.
Lindsay
I ordered my first sleep sack for my daughter when she was a newborn and it did fit nicely. I decided to order another one now that she is 9 months. I got the 0.5 in her age bracket, since summer is approaching and it does get quite warm where I live. My daughter is quite long, in the 95th percentile for height and weight. I feel that the sleep sack is a bit small for her. It does fit her currently, but I feel like she will outgrow it by next month.
Kayla H.
Better sleep was on the way! We love this sleep sac. We have tried so many but now that he is starting to roll he doesn't care much for them. This one keeps him warm when the AC is on but cool enough to sleep well. We love that we can flip it around to provide comfort in different ways.
Jessica F.
Hasn’t helped my baby with sleeping, but keeps him warm.
Johanna L.
Great material, and looks great, but did nothing for sleep. It’s hopeless!
Jennifer F.
Love the pattern!
Jennifer F.
These sleep sacks are the best!
Kate R.
my little one loves her zen sack!
Colleen F.
We have a Zen Sack Classic and a Zen Sack Quilted and despite being the same size they are significantly different. The Zen Sack Classic is 3 inches shorter than the same size of the Zen Sack Quilted. We love the product just wish there was some consistency in the sizing. The classic was a waste of money for us since our son never fit in it despite still fitting comfortably in the quilted version.
Celia S.
My 16 month old had a sleep regression. I ordered baby melatonin and this sleep sack. Both helped. I tossed all the other sleep sacks and only use this one. My daughter sleeps on her tummy so I put the weighted part on her back.
Karen B.
Love this product. Our son is a great sleeper but he was starting to roll over in the Magic Merlin suit. We switched to the Nested Bean after a friend recommended it. Took one night for him to get the hang of it. The suit is so cute, the fabric soft.
My only question is - if he rolls on to his stomach, will the weighted bean that’s sewn into the chest area be uncomfortable, preventing him from sleeping in that position?
Hannah S.
This is our third nested bean sleep sack! We really like them, but we’ve never tried anything else so I can’t compare it to anything else.
Lisa R.
Bought as a gift
Vanessa D.
Our newborn hates to be restricted and loves having her hands and arms free as she sleeps now 7+ hours through the night!
Kaitlin D.
Love the material this is made of! I have a super hot natured baby and this is perfect for him.
Courtney W.
Super soft & my daughter is sleeping through the night!
Jasmine N.
It’s okay, I got it when my son was 6 months and he did struggle at first to sleep in swaddled and not sure if the weighted area helped much, but he is sleeping better through the day and night, not fully sleeping through the night still. Not sure if the sack is helping in any way but definitely was worth a try.
Melissa W.
My tiny human falls asleep in less than 10 minutes with the Nested Bean Zen Sack! He sleeps longer stretches and is knocking that 4 month sleep regression out of the park!
Katie K.
We liked this sack for our daughter who is 2 and a half months now. She never really liked swaddles, and this would keep her legs covered without constricting her. My only criticism is that I feel like the shoulder straps are too snug on her. Especially for a 0-6 month fit. Had I known this, I probably would have gotten a size up. So now we only use it occasionally.
Melissa W.
I’ve bought a lot of sleep sacks between 2 babies and this one is fine. I’m not a big fan of the shoulder snaps as they allow for minimal adjustment but otherwise are hard to mess with at night (if you want to fully remove it for a feeding) and they add some bulk.
Adele C.
I absolutely love this zen sack! My daughter has slept through the night since using this when she was around 4 months old. I would highly recommend giving it a shot. I know that every baby is different, but this may be the missing piece for you to get your baby to sleep through the night like it was for me!
Paola H.
It really works!! My baby boy is about to be 4 months next week and he has been slepping 6 / 7 hours at night I got a size 6-15 months and I am glad I did (he is a tall baby)
The sleep sack is super soft and cute!
olivia s.
I can’t say that it’s made a difference in his sleep. Will keep trying
Mary T.
Exactly what I wanted! We have used the nested bean sleep sacks for a while and love them! Just needed a new one for my new little guy.
Amber D.
The material of this sleep sack is so smooth. It doesn’t get too hot for my baby and keeps him comfy all night!! Will definitely be buying this as gifts and in bigger sizes!
Philip M.
Our little guy has used one of these essentially since birth. He grew out of the old one and seems to be liking this bigger size so far. Would recommend.
Frequently asked questions
-
How much weight is in the Zen Sack® Classic sleep sack?
All Zen sleep sacks feature a built-in Cuddle Pad™, which weighs just 30 grams (Small size) 60 grams (Medium size) and 90 grams (Large size and distributed across the chest). Our baby sleep sacks are safely weighted in key areas as opposed to all-weighted sleep sacks or weighted blankets, which the AAP has deemed unsafe for infants.
-
What’s the difference between Nested Bean weighted baby sleep sacks products?
Nested Bean offers a variety of sleep sacks, all of which are designed to calm like your embrace: Zen Sack® Classic, Zen Sack® Premier, Zen Sack® Winter and Zen Sack® Quilted. The difference between our weighted sleep sacks is the fabric used for construction. Zen Sack® Classic is made from 100% breathable cotton, and is perfect for year-round use. Zen Sack® Premier ,made from 70% rayon from bamboo for luxurious softness and 30% cotton for strength, is lightweight for warmer temps. Zen Sack® Winter is made from 100% cotton, with a 2.5 TOG and heavy poly-fiber filling for colder weather. And Zen Sack® Quilted is a cozy transitional sleep sack, for when temps start to drop.
-
Are Nested Bean weighted baby sleep sacks safe for babies who roll over?
All Zen Sack® sleep sacks were designed for rollers and tummy sleepers; they help babies get longer, more peaceful sleep through all growth stages. The Small and Medium size sleep sacks have a gently weighted Cuddle Pad™ on the front that is so light and flexible, it nearly flattens when baby rolls to their tummy. The sleep sack can also be reversed and worn backwards for tummy sleepers who roll independently, placing the weighted center on baby's back for uninterrupted comfort all night.
-
What is the Cuddle Effect™—and how do Nested Bean sleep sacks trigger it?
The Cuddle Effect is a proven metabolic response that babies experience when they are held, that triggers relaxation and well-being, improves sleep and promotes healthy development. Research on Deep Touch Pressure (DTP) shows that babies experience the Cuddle Effect when they feel gentle pressure in the places you naturally hold them. Nested Bean sleep sacks are designed with gently weighted Cuddle Pads™ that calm like your embrace and trigger the Cuddle Effect for longer sleep.
-
Do Nested Bean weighted sleep sacks meet industry safety standards?
Nested Bean baby sleep sacks adhere to all Consumer Product Safety Commission guidelines around product construction, flammability and more. The Cuddle Pad™ in our sleep sacks is self-contained and cannot cause overheating, and the gentle weight does not restrict movement: For example, the Zen Sack™ sleep sack is safe for tummy sleepers, rollers and side sleepers.
-
When should you start using a Nested Bean sleep sack?
Once babies start rolling, swaddling stops—and it’s time to transition to a baby sleep sack. Only Nested Bean sleep sacks contain Cuddle Pads™ that are gently weighted to ease the transition from swaddle to sleep sack, so babies experience uninterrupted comfort and longer sleep.
-
How long does it take Nested Bean sleep sacks to work?
As with all our gently weighted Zen Sleepwear™, most parents report that our baby sleep sacks improve their baby’s sleep in 1 to 3 nights.
-
What is TOG—and how does it differ between Nested Bean sleep sacks?
TOG is a measure of thermal insulation. It is a commonly used term the textile industry to indicate how warm clothing is. The higher the TOG in baby sleep sacks, the better thermal insulation it provides and the warmer it is. For example, the Zen Sack® Classic sleep sack has a TOG of 0.5, perfect for year-round use. The bamboo Zen Sack® Premier sleep sack has a TOG of 0.3, for warmer weather. The Zen Sack® Quilted sleep sack has a TOG of 1.0, great as temps begin to fall. And the Zen Sack® Winter sleep sack has a cozy TOG of 2.5, just right for chilly nights.
-
What is the Grow-with-Me feature of Nested Ben sleep sacks?
Nested Bean sleep sacks contain 2 sets of snaps on the shoulders. The bottom snap offers a snug fit, while the top snap offers more room as your baby grows.
-
How do Nested Bean sleep sacks hold up in the washing machine?
All Nested Bean weighted baby sleep sacks are made of the highest-grade fabrics, and are designed to be super durable and withstand multiple washings. To protect the fabric quality, we recommend washing our baby sleep sacks in cold water, on a gentle cycle and tumble dry on low heat.
