I think this product is good quality, the fabric is very soft, would like to try the winter zen sac since I live in a cold climate. My only complaint is I wish the front and the back had a nested bean. My child gets put to bed on his back and it helps him stay asleep once he is put down. But at some point in the night he flips over to his belly. I am afraid to put it on backwards thinking that the first half of his night won't go as well.

It makes the difference!
We tried many swaddles, weighted suits, etc and we finally found the good one for my little one.
Nicole P.
After one wash (in a net washing bag) and air drying the zipper is completely annoying and waved. it makes unzipping extremely annoying mid night
Grace H.
okay so it’s a great product. i think the promise of better sleep in 1-3 nights is insane unless you’re starting with a new born. my daughter is 7 months and now we’re crib training it has definitely helped her stretch out her sleep windows but it’s not a magic fix unfortunately. helps with longer naps at least
Taylor
I recently moved my 9 week old into her crib alone in her room. She was getting some stretches of sleep in her bassinet in our room, but nothing like now. She slept 8-10 hours the first night with her nested sleep sack in her crib. Her dad and I were shocked. Totally recommend!
Alexis R.
I’m not seeing much of a change in my child’s sleep patterns quite yet, I’m still hopeful!
Tiffany W.
Game changer. If you are thinking about buying one go ahead and do it! I was back and forth but finally caved in. Once it arrived my little babe has been sleeping like a rock! She’s 3.5 months and we was getting up every two hours and she was always kicking and moving around. Not any longer.. she sleeps in 6 hour stretches and twice she’s slept through the night!!! It’s been two weeks and I couldn’t be happier with my purchase!!
Briana L.
Both of my kids love the Nested Bean products!
Leah L.
This sleep sack has helped my son fall asleep quicker. Love it!
Natalie G.
The first few nights have been amazing with our nested bean sack!
Allison D.
Bought this to see if it would help my 3 month old sleep longer periods without waking. First night of using she slept 5 hours between bottles which is a huge victory since it had been every 2-3 hours since birth. Definitely will be purchasing more! Great quality also. It holds up well to washing. All smiles the next morning too!
Sarah L.
Best sleep sack ever. My daughter won’t get settled without it. I love how it is gently weighted in the middle, but it isn’t too heavy at all. It’s also SUPER easy to put on. I put it on her last night without her even waking up. Great purchase! Highly recommend.
Brooke M.
Love the nested bean! I have been using it on my baby since she started rolling and she is 15 months and still wearing one!!
adrienne j.
My little one has been sleeping in Nested Bean since 3 months! She has always loved them. She touches the bean while falling asleep. It really comforts her. She’s a size 15 months now and I ordered new sleepers. The new ones don’t have a bean, the weight is distributed across the entire chest and not centralized. She feels for it and then isn’t so happy since it isn’t there
Cheri C.
Our baby is sleeping through the night! It's amazing!
Kelsey R.
Absolutely love it, i was skeptical at first but glad we tried it. My daughter falls asleep on her own in about 15 mins and sleeps longer than she ever did before!
Natalie L.
I bought this in hope my little one would begin sleeping longer periods. He stopped sleeping through the night at the 4 month mark. I have not seen a drastic change in his sleep since using the sleep sack. I do however, like the design and the simplicity of it. I do plan to try some of Nested Beans other products in hope that maybe that will help.
Virginia T.
In 4 nights my baby was sleeping thru the night! He would wake up every 2 hrs before the sleep sack!
Bailey S.
It is not an instant fix. It takes a couple of nightsm however now when we break out her sleep sack she knows nap time or bedtime is upon her!
Stephanie H.
I bought the Zen sack in desperation at 2 am when my four month old’s stretches of sleep were becoming shorter with each passing day. I used the sack as soon as it came in, practiced a 5 min interval sleep training method, and she started sleeping though the night almost immediately. I would buy this product for any new parent or a parent with child going through sleep regressions!
Maggie A.
It’s alright. They’ve changed the style since a couple years ago and I liked them better before. The quality isn’t as much.
Elizabeth G.
A nice sleep sack for a reasonable price. Comfy and soft material. Functional side zipper works well for night changes. Not a dramatic difference in sleep for my babe with it but we like it the best of our sleep sacks and use it every nap/night.
Miranda H.
My son loves this sleep sack more than any other one we’ve tried! within a week he was sleeping better & longer stretches!
Kimberly S.
It took about 5 days for my sweet boy to sleep all night after using the sak. He loves to be nice and warm and the sak offers that to him as well as the comfort of the weighted owl on his chest to feel like my hands/chest are on him. It has been the greatest baby item I have purchased yet! Worth every penny.
Amanda B.
We love our nested bean sack! This is our 4th one, and the first of the larger version. Our LO is about to turn one so could transition to a blanket but moves so much in her sleep, this sack is perfect to make sure she stays warm. She also falls asleep with us touching her chest usually, so the weight helps to keep her asleep!
Additionally, the Nested Bean team has some amazing customer service as we had ordered the wrong size originally. Such a wonderful company!
Sarah P.
My baby absolutely loves his!
Nicola C.
Light and easy to use!
Carolina R.
It has significantly helped my baby sleep longer throughout the night! It’s been life changing
Dominique R.
I was so nervous to transition my daughter out of her swaddles after hearing so many stories of babies having sleeping issue after but we switched her to nestedbean at 3.5 months and no issues at all. She is sleeping all night and we’re loving this product!!! Definitely getting more!
Anna L.
Good
Ana A.
The arm holes should be slightly larger and the sack should be a bit longer
Odetta S.
Its been a miracle worker it really works i was very skeptical about ordering it but I'm so happy I did great product.
Kate P.
Started only waking up once a night as soon as we started using the sleep sack. And we are both happier for it!
Crickett J.
My son has been using the zen sack since he was 6 months old, he’s now 15 months. We just upgraded to the size large (15-24 months) and it’s absolutely wonderful. Both zen sacks he’s had have been great! Well made, my son loves it, easy to wash, and cozy! I absolutely recommend the zen sack!
Danielle P.
Transitioned from the swaddle straight to this and I cannot believe how much better she is sleeping!
Kady M.
My baby just turned 3 months and has been using these for about a month. She sleeps from about 8pm to about 2:30am every single night without waking up, eats, and then goes back to sleep! These have been amazing at helping with the transition into her crib.
Hannah A.
Good sleep sack but didn’t help my baby sleep.
Brittaney M.
This sleep sack is so great. Our 8 week old wouldn't sleep unless he was touching his momma. Needless to say momma was getting no sleep. Once we put him in the sleep sack we were able to lie him down in his bassinet without waking up. He’s now 12 weeks and sleeping throughout the night in his bassinet.
Heather S.
It's so snuggly and soft. My baby girl absolutely loves it! Highly recommend.
Kassandra G.
Before I got the sleep sack, my baby was waking me up every couple of hours fussing. Me and him both were exhausted. I thought these sleep sacks were too good to be true but I was desperate to help him sleep so I bought one. It was literally the best money spent. He’s sleeping all night long and doesn’t wake up to eat til 8 am. Only waking me up once or twice for his paci. This thing is a life saver.
Renee S.
We love it!
Bethany S.
Made no difference in sleep. its a hassle to get it on if your baby has already fallen asleep- they will wake up when you are trying to get them in.
best to put it on them pre-emptively, then let let soothe themselves to sleep.
We find that it has brought us no relief but is a nice wearable blanket ♀️
Krystin S.
We love this sleep sack! My baby went from waking every couple hours to sleeping 4-6 hour stretches. It’s soft, seems comfy, and he seems to really like sleeping in it!
Elizabeth D.
We love our sleep sack and so does our little guy!!
KRYSTAL T.
Thank you so much. My baby is already crawling at 2 months so this keeps him in one spot and helps him sleep.
Kim T.
I'm usually super skeptical bc why spend the money if u dont think your LO wont like it/help him sleep. We've tried many diff swaddles and he could care less and will still wake up every 2 or 3 hours no matter what time of day/night and we were just frustrated esp with the cluster feedings so no one gets real sleep! He especially sleeps with arms out and it's hard to find one out there that does the job. First night putting on the sack wasn't terrible. We got 4 hours of sleep and one overnight feeding. So that's nice and refreshing for all. But the next morning after I woke up in disbelief and scared maybe I didn't hear our child... 6 hours...next day 7.5 hours...and it's been consistent from there on out. My LO is now 7 weeks old and still sleeps over 6 hours or more overnight. It's made a huge diff. Gonna purchase one or two more when I have the funds. Super soft and easy to put on and the weighted bean is just enough and not too heavy. Purchased the zen one swaddle as well and the length was kind of short so I gifted it to my best friend who's having their first LO in March. Gonna try and buy the next size up for sure! So excited this worked out!
Katrina T.
Absolutely love this sleep sac! It has been a total game changer for me! My first child was a horrible sleeper so I just knew my second would struggle as well. A family member suggested I try the nested bean because they had such a positive experience and WOW! My 6 week old was sleeping in 7 hour stretches!! You need to try it- your baby will love it!
Ashley H.
My only regret is not ordering the zen sack sooner! My baby hated her swaddle but she slept so good with it, I tried slowly weaning her off of it 4 months and it was hell so I kept swaddling her, it wasn’t till she started rolling over with it that I knew I had to really commit to not swaddling her but I was scared. First night with the zen sack was kinda hard but but her first nap that next day it was magical! Not only for her but for me as well, I sleep better at night knowing that if she rolls over her hands are free for her to lift herself up or roll back over. 10/10 recommend.
PRISCILLA C.
absolutely in love!!
Karen B.
Unfortunately did not work with my baby. I had high hopes for this product… my baby is three months old and did not sleep longer at all.
Cassandra M.
I was hesitant to try this because I thought it probably wouldn’t work for our girly, even if it worked for so many others. But, after several months, when I got the email that it was on sale for Cyber Monday, I finally decided it was worth a try. First night, our 6-month-old went from waking EVERY 45 minutes to an hour, to sleeping a 3 hour stretch!! That may not sound great compared to “sleeping through the night”, but for us it is progress!! About a month in, 3 hours is still as long as it seems to take her, but still so glad we got it, because like I said, it’s progress. Also, our girl does like to sleep on her side or tummy, so we put this on her backwards, with the weighted bean on her back.
Other perks, I love that this is 100% cotton. It’s so soft and has held up beautifully so far!
Kailea D.
I like that this functions as a wearable blanket that’s safe and won’t go up around baby’s face. This gives me peace of mind. I think it probably helps a little with sleep since it’s cozy, but I haven’t seen a miraculous change. I think it was worth the buy!
Lynne B.
We love the nested bean sleep sack! It has totally transformed our daytime naps. Highly recommend. Easy to use and quickly effective.
Angela B.
Can't wait to try it out
Haley H.
The lavender is such a pretty color. I love the material and the snap + zipper closure. Very easy to get on and off and opens enough for diaper changes.
Miranda L.
Our daughter is 4 months old and will sleep the entire with this sack on. We love that it’s light weight and isn’t tight around the abdominal like swaddles. Will be buying more !
Amanda B.
We love the nested bean sleep sack! I did a lot of research on what might work for our little one, and this was a great option that didn't break the bank.
On top of improved sleep- their customer care team is amazing! They are so helpful and kind. I ordered the wrong size and their team quickly corrected my mistake. I will definitely continue buying from Nested Bean!
Lauren C.
This sleep sack is awesome! Helped our 2 month old get through the night when he didn’t get swaddled. Love the touch of the weight on the front.
taylor w.
Can’t wait to use the nested bean and get great results! It was recommended from a friend and she raves about it.
Candice S.
I haven’t been able to tell that it’s helping my daughter sleep longer throughout the night like I had hoped. She does like her arms out so that’s a nice feature.
Emily T.
My daughter has used Nested Bean since she was 3 months old and has slept throughout the night ever since! We love these sleep sacks!
Gemarie M.
My baby slept 5hrs straight on the first night she wore her sleepsack, and she has never done that before, usually she only sleeps 2-3hrs and she’s up again. She’s been sleeping 5-7hrs straight at night now. This has been a lifesaver for real!
Jeanette C.
Sleep sack was a gift for my 2 month old grandson.
This his second sack. My daughter says that it helps him sleep very deeply, waking only for his feedings at night.
Wonderful product!
Bailey E.
My baby has not slept for more than 2-3 hours at a time since he was born. We started using this sleep sack at 9 months old and now he consistently does 5 hour stretches through the night. Game changer!
Megan O.
My little one went from every 1 to 2 hours of sleep at night, too every 4 to 5 hours of sleep.
Lauren W.
Our little guy loves the nested bean sleep sack. He definitely falls into a deeper sleep quicker when wearing it. The material is high quality - highly recommend.
Megan D.
We had tried everything to get our sweet girl to sleep through the night. Nothing worked. I had a friend recommend the Zen Sack and while we have spent money on several products that hadn’t worked, I was willing to try. Needless to say she can now sleep 7 hours straight and in her own crib!! I have bought 2 more sacks because I don’t want her to be without one!! This has been one of our best purchases.
Katie G.
We started out with a Dreamland Baby sleep sack / swaddle combo- it was a great product, but it’s weight & functionality made placing our baby in the burping position extremely difficult during those night feeds. The zipper (which I was not a fan of) would rise up into her neck, making the top of the sleep sack bunch up into her face. We’d ended up having to take the sleep sack off, feed, burp, put the sleep sack back on & then lay down- by this time, baby was too awake to have an easy transition back to sleep.
Then we stumbled upon Nested Bean & it was an absolute game changer for SO many reasons. We currently own 4 sleep sacks. One bamboo, 2 cotton & 1 winter TOG. There are so many smart details that make you want to use this sleep sack wether you choose to believe in the science behind the weighted chest or not! First- the material on all 3 are phenomenal. It’s exactly what you’d expect. They wash SO well. We have a reflux baby & these sleep sacks are washed 3-4 times a week. Second- the zipper!!! It zips around the side like a sleeping bag & buttons over the shoulders- this keeps a sharp zipper from hitting under baby’s chin / neck & keeps the sleep sack from rising & covering their face. Not to mention, it’s a double zipper, that makes diaper changes a breeze! We can also feed, burp, change diapers etc during the night without ever having to take the sleep sack off! Third- the weighted chest! Wether it was purely coincidental or not..we went to the beach last month and I forgot both sleep sacks in the dryer before leaving! We thought we could just pick up a regular sleep sack from target & be good to go. Nope! She was so unsettled for 3 nights. I immediately hopped on Nested Bean and paid for the fastest shipping to our beach house & the day we received it, we washed it, used it that night, she slept 11 hours & only woke up once to feed. Coincidence or not…I was sold! I don’t see us ever buying another brand!
Joslin E.
I love it, but on the 0-6 month size, they arm holes should be bigger. I have the leave the side with the zipper in zipped and the other side is snug. Baby is 4 months wearing 3-6 months. Other than that, I do plan to purchase the next size up for him soon.
Kendyl W.
This is so soft and my baby loves it. The gentle weight helps him settle and sleep so much better. Also, my baby is super tall and this is finally long enough for him! Most sleep sacks are so short but this is super long. He can use it for a long time.
DeeAnna B.
Our baby was extremely premature so she was swaddled for a very long time until she finally learned to roll. We bought a size medium nested bean sleep sack and she transitioned very smoothly. She’s now almost 2 and we upgraded to the size large. She loves it and brings it to us every night when it’s time to put on jammies.
Teresita C.
We needed to transition our baby out of swaddle to a sack and this works wonders on us. Within 3 nights she got usto it and now we use for every nap and every night.
Malea F.
Fantastic!!
Lisa K.
These sleep sacks are the best. I started using them when my baby was a month old and never looked back! He just turned 5 months and I had to upgrade to the 6-12 month for the length.
Emily K.
I bought this when transitioning my 4 month old from a bassinet to crib. Not sure if it was luck or if I can credit this fully but the transition went super smooth. There was hardly any of the "crying it out" part so I just keep using it because I don't want to jinx anything. I also love the fact it's like a baby sleeping bag and she can't pull it over her face. I'd recommend this to anyone and have already bought the next size up.
Brittany S.
Before using the our sleep sac my boy was getting up several times a night. Now at only 6 weeks he sleeps all night long, he absolutely loves his sleep sac
Nichoal D.
We love our sleep sac. My little one loves having his hands free but still feels the sense of security with the weighted egg on top.
Kiersten H.
Continue to love the nested bean products. Our baby has been in all and loves the little bean bag for comfort. Easy in and out, durable, and out baby's favorite! Currently using the largest size.
Jennifer S.
My grandson loves it sleeping very good
Charlotte W.
I was desperate. My 9 month old son stopped sleeping and was waking multiple time when he used to sleep soundly through the night. Night one was drastic improvement by night 3 he was sleeping through the night again! I will be buying more.
Estrella C.
Super easy to put on and it has helped my son sleep through the night on his own!! It's helping him with self soothing at night when he stirs awake.
Cort P.
Wonderful!
Brieanna
After using the sleep sack for three days he started sleeping through the night!
Best thing ever so worth buying
Chloe N.
We have been using nested bean since 5 months and we are hooked!! Will definitely use if I have anymore babies.
Sylvia G.
Wow! I was skeptical but it really helped my baby sleep better! She was waking up 30-45 mins into nap time and now I have to wake her! At night she’s giving us a solid 7 hr stretch! I feel like a brand new woman! She’s 11 weeks old and is in the size small sleep sack original
Rachel
The first couple days I couldn’t really decide if the nested bean sleep sack was worth it but then by day 4 my little guy (6 months) was sleeping from 9:15-4. He had been waking up every 2-3 hrs throughout the night which was rough on my baby and myself due to lack of sleep. I’m very thankful I’ve possibly found something, ALL natural, that is allowing my baby to sleep longer
Kaylie D.
This is our second purchase for our baby. We LOVE Nested Bean. They are worth every penny.
Creed P.
Desperate 3am purchase been a couple weeks of use. Nice quality and design that will fit our girl for a while, for now the light wieght on the chest has no effect on soothing her or increased sleep. I think its just making her stronger as she planks and postures.

We love the sack but this one is damaged after one wear. The zipper has pulled off of the sack itself. I wrote to customer service and have her to hear back.
Carmen B.
This sleep sack is perfect for comforting little ones as they drift off to dreamland :) highly recommend!
Jessica A.
Works great! Baby flales less! I can tell she feels much more comforted with the weather beans!
Gloria H.
This works wonders. Baby hates swaddles that don’t allow him to move his arms around and this was the perfect option.
Jennifer C.
Don’t understand why the large tag is on the outside but we love the sleep sack
Lisa P.
The material is so soft and our little guy loves this sleep sack! We’ve used these since he was a newborn!
Julia L.
First of all, it shipped so fast! Second of all she is FINALLY falling asleep in her bassinet and staying asleep when I put her down. Without the sleep sack she would wake up IMMEDIATELY when I put her down. I’m so glad I found this! I definitely recommend
Mark S.
When we ordered the Zen Sac Classic not we were hopeful, but weren’t expecting drastic results. We have been pleasantly surprised by how well it has worked. It took one night for our 8-month old to acclimate, but has slept through night since. She was previously waking up 3-5 times a night. Couldn’t recommend it enough!
Hunter H.
My daughter loves it!
Sierra S.
We love these! I work at an early learning center and we ordered these for our infant rooms; big hit with the babies and their families. I order them now as gifts.

Good sleep sack but didn’t help my baby sleep.
Brittaney M.
This sleep sack is so great. Our 8 week old wouldn't sleep unless he was touching his momma. Needless to say momma was getting no sleep. Once we put him in the sleep sack we were able to lie him down in his bassinet without waking up. He’s now 12 weeks and sleeping throughout the night in his bassinet.
Heather S.
It's so snuggly and soft. My baby girl absolutely loves it! Highly recommend.

Before I got the sleep sack, my baby was waking me up every couple of hours fussing. Me and him both were exhausted. I thought these sleep sacks were too good to be true but I was desperate to help him sleep so I bought one. It was literally the best money spent. He’s sleeping all night long and doesn’t wake up to eat til 8 am. Only waking me up once or twice for his paci. This thing is a life saver.
Renee S.
We love it!

Made no difference in sleep. its a hassle to get it on if your baby has already fallen asleep- they will wake up when you are trying to get them in.
best to put it on them pre-emptively, then let let soothe themselves to sleep.
We find that it has brought us no relief but is a nice wearable blanket ♀️
Krystin S.
We love this sleep sack! My baby went from waking every couple hours to sleeping 4-6 hour stretches. It’s soft, seems comfy, and he seems to really like sleeping in it!
Elizabeth D.
We love our sleep sack and so does our little guy!!
KRYSTAL T.
Thank you so much. My baby is already crawling at 2 months so this keeps him in one spot and helps him sleep.

I'm usually super skeptical bc why spend the money if u dont think your LO wont like it/help him sleep. We've tried many diff swaddles and he could care less and will still wake up every 2 or 3 hours no matter what time of day/night and we were just frustrated esp with the cluster feedings so no one gets real sleep! He especially sleeps with arms out and it's hard to find one out there that does the job. First night putting on the sack wasn't terrible. We got 4 hours of sleep and one overnight feeding. So that's nice and refreshing for all. But the next morning after I woke up in disbelief and scared maybe I didn't hear our child... 6 hours...next day 7.5 hours...and it's been consistent from there on out. My LO is now 7 weeks old and still sleeps over 6 hours or more overnight. It's made a huge diff. Gonna purchase one or two more when I have the funds. Super soft and easy to put on and the weighted bean is just enough and not too heavy. Purchased the zen one swaddle as well and the length was kind of short so I gifted it to my best friend who's having their first LO in March. Gonna try and buy the next size up for sure! So excited this worked out!
Katrina T.
Absolutely love this sleep sac! It has been a total game changer for me! My first child was a horrible sleeper so I just knew my second would struggle as well. A family member suggested I try the nested bean because they had such a positive experience and WOW! My 6 week old was sleeping in 7 hour stretches!! You need to try it- your baby will love it!
Ashley H.
My only regret is not ordering the zen sack sooner! My baby hated her swaddle but she slept so good with it, I tried slowly weaning her off of it 4 months and it was hell so I kept swaddling her, it wasn’t till she started rolling over with it that I knew I had to really commit to not swaddling her but I was scared. First night with the zen sack was kinda hard but but her first nap that next day it was magical! Not only for her but for me as well, I sleep better at night knowing that if she rolls over her hands are free for her to lift herself up or roll back over. 10/10 recommend.
PRISCILLA C.
absolutely in love!!

Unfortunately did not work with my baby. I had high hopes for this product… my baby is three months old and did not sleep longer at all.
Cassandra M.
I was hesitant to try this because I thought it probably wouldn’t work for our girly, even if it worked for so many others. But, after several months, when I got the email that it was on sale for Cyber Monday, I finally decided it was worth a try. First night, our 6-month-old went from waking EVERY 45 minutes to an hour, to sleeping a 3 hour stretch!! That may not sound great compared to “sleeping through the night”, but for us it is progress!! About a month in, 3 hours is still as long as it seems to take her, but still so glad we got it, because like I said, it’s progress. Also, our girl does like to sleep on her side or tummy, so we put this on her backwards, with the weighted bean on her back.
Other perks, I love that this is 100% cotton. It’s so soft and has held up beautifully so far!
Kailea D.
I like that this functions as a wearable blanket that’s safe and won’t go up around baby’s face. This gives me peace of mind. I think it probably helps a little with sleep since it’s cozy, but I haven’t seen a miraculous change. I think it was worth the buy!
Lynne B.
We love the nested bean sleep sack! It has totally transformed our daytime naps. Highly recommend. Easy to use and quickly effective.
Angela B.
Can't wait to try it out
Haley H.
The lavender is such a pretty color. I love the material and the snap + zipper closure. Very easy to get on and off and opens enough for diaper changes.
Miranda L.
Our daughter is 4 months old and will sleep the entire with this sack on. We love that it’s light weight and isn’t tight around the abdominal like swaddles. Will be buying more !
Amanda B.
We love the nested bean sleep sack! I did a lot of research on what might work for our little one, and this was a great option that didn't break the bank.
On top of improved sleep- their customer care team is amazing! They are so helpful and kind. I ordered the wrong size and their team quickly corrected my mistake. I will definitely continue buying from Nested Bean!
Lauren C.
This sleep sack is awesome! Helped our 2 month old get through the night when he didn’t get swaddled. Love the touch of the weight on the front.
taylor w.
Can’t wait to use the nested bean and get great results! It was recommended from a friend and she raves about it.
Candice S.
I haven’t been able to tell that it’s helping my daughter sleep longer throughout the night like I had hoped. She does like her arms out so that’s a nice feature.
Emily T.
My daughter has used Nested Bean since she was 3 months old and has slept throughout the night ever since! We love these sleep sacks!
Gemarie M.
My baby slept 5hrs straight on the first night she wore her sleepsack, and she has never done that before, usually she only sleeps 2-3hrs and she’s up again. She’s been sleeping 5-7hrs straight at night now. This has been a lifesaver for real!
Jeanette C.
Sleep sack was a gift for my 2 month old grandson.
This his second sack. My daughter says that it helps him sleep very deeply, waking only for his feedings at night.
Wonderful product!
Bailey E.
My baby has not slept for more than 2-3 hours at a time since he was born. We started using this sleep sack at 9 months old and now he consistently does 5 hour stretches through the night. Game changer!
Megan O.
My little one went from every 1 to 2 hours of sleep at night, too every 4 to 5 hours of sleep.
Lauren W.
Our little guy loves the nested bean sleep sack. He definitely falls into a deeper sleep quicker when wearing it. The material is high quality - highly recommend.
Megan D.
We had tried everything to get our sweet girl to sleep through the night. Nothing worked. I had a friend recommend the Zen Sack and while we have spent money on several products that hadn’t worked, I was willing to try. Needless to say she can now sleep 7 hours straight and in her own crib!! I have bought 2 more sacks because I don’t want her to be without one!! This has been one of our best purchases.
Katie G.
We started out with a Dreamland Baby sleep sack / swaddle combo- it was a great product, but it’s weight & functionality made placing our baby in the burping position extremely difficult during those night feeds. The zipper (which I was not a fan of) would rise up into her neck, making the top of the sleep sack bunch up into her face. We’d ended up having to take the sleep sack off, feed, burp, put the sleep sack back on & then lay down- by this time, baby was too awake to have an easy transition back to sleep.
Then we stumbled upon Nested Bean & it was an absolute game changer for SO many reasons. We currently own 4 sleep sacks. One bamboo, 2 cotton & 1 winter TOG. There are so many smart details that make you want to use this sleep sack wether you choose to believe in the science behind the weighted chest or not! First- the material on all 3 are phenomenal. It’s exactly what you’d expect. They wash SO well. We have a reflux baby & these sleep sacks are washed 3-4 times a week. Second- the zipper!!! It zips around the side like a sleeping bag & buttons over the shoulders- this keeps a sharp zipper from hitting under baby’s chin / neck & keeps the sleep sack from rising & covering their face. Not to mention, it’s a double zipper, that makes diaper changes a breeze! We can also feed, burp, change diapers etc during the night without ever having to take the sleep sack off! Third- the weighted chest! Wether it was purely coincidental or not..we went to the beach last month and I forgot both sleep sacks in the dryer before leaving! We thought we could just pick up a regular sleep sack from target & be good to go. Nope! She was so unsettled for 3 nights. I immediately hopped on Nested Bean and paid for the fastest shipping to our beach house & the day we received it, we washed it, used it that night, she slept 11 hours & only woke up once to feed. Coincidence or not…I was sold! I don’t see us ever buying another brand!
Joslin E.
I love it, but on the 0-6 month size, they arm holes should be bigger. I have the leave the side with the zipper in zipped and the other side is snug. Baby is 4 months wearing 3-6 months. Other than that, I do plan to purchase the next size up for him soon.
Kendyl W.
This is so soft and my baby loves it. The gentle weight helps him settle and sleep so much better. Also, my baby is super tall and this is finally long enough for him! Most sleep sacks are so short but this is super long. He can use it for a long time.
DeeAnna B.
Our baby was extremely premature so she was swaddled for a very long time until she finally learned to roll. We bought a size medium nested bean sleep sack and she transitioned very smoothly. She’s now almost 2 and we upgraded to the size large. She loves it and brings it to us every night when it’s time to put on jammies.
Teresita C.
We needed to transition our baby out of swaddle to a sack and this works wonders on us. Within 3 nights she got usto it and now we use for every nap and every night.
Malea F.
Fantastic!!
Lisa K.
These sleep sacks are the best. I started using them when my baby was a month old and never looked back! He just turned 5 months and I had to upgrade to the 6-12 month for the length.
Emily K.
I bought this when transitioning my 4 month old from a bassinet to crib. Not sure if it was luck or if I can credit this fully but the transition went super smooth. There was hardly any of the "crying it out" part so I just keep using it because I don't want to jinx anything. I also love the fact it's like a baby sleeping bag and she can't pull it over her face. I'd recommend this to anyone and have already bought the next size up.
Brittany S.
Before using the our sleep sac my boy was getting up several times a night. Now at only 6 weeks he sleeps all night long, he absolutely loves his sleep sac
Nichoal D.
We love our sleep sac. My little one loves having his hands free but still feels the sense of security with the weighted egg on top.
Kiersten H.
Continue to love the nested bean products. Our baby has been in all and loves the little bean bag for comfort. Easy in and out, durable, and out baby's favorite! Currently using the largest size.
Jennifer S.
My grandson loves it sleeping very good
Charlotte W.
I was desperate. My 9 month old son stopped sleeping and was waking multiple time when he used to sleep soundly through the night. Night one was drastic improvement by night 3 he was sleeping through the night again! I will be buying more.
Estrella C.
Super easy to put on and it has helped my son sleep through the night on his own!! It's helping him with self soothing at night when he stirs awake.
Cort P.
Wonderful!
Brieanna
After using the sleep sack for three days he started sleeping through the night!
Best thing ever so worth buying
Chloe N.
We have been using nested bean since 5 months and we are hooked!! Will definitely use if I have anymore babies.
Sylvia G.
Wow! I was skeptical but it really helped my baby sleep better! She was waking up 30-45 mins into nap time and now I have to wake her! At night she’s giving us a solid 7 hr stretch! I feel like a brand new woman! She’s 11 weeks old and is in the size small sleep sack original
Rachel
The first couple days I couldn’t really decide if the nested bean sleep sack was worth it but then by day 4 my little guy (6 months) was sleeping from 9:15-4. He had been waking up every 2-3 hrs throughout the night which was rough on my baby and myself due to lack of sleep. I’m very thankful I’ve possibly found something, ALL natural, that is allowing my baby to sleep longer
Kaylie D.
This is our second purchase for our baby. We LOVE Nested Bean. They are worth every penny.
Creed P.
Desperate 3am purchase been a couple weeks of use. Nice quality and design that will fit our girl for a while, for now the light wieght on the chest has no effect on soothing her or increased sleep. I think its just making her stronger as she planks and postures.

We love the sack but this one is damaged after one wear. The zipper has pulled off of the sack itself. I wrote to customer service and have her to hear back.
Carmen B.
This sleep sack is perfect for comforting little ones as they drift off to dreamland :) highly recommend!
Jessica A.
Works great! Baby flales less! I can tell she feels much more comforted with the weather beans!
Gloria H.
This works wonders. Baby hates swaddles that don’t allow him to move his arms around and this was the perfect option.
Jennifer C.
Don’t understand why the large tag is on the outside but we love the sleep sack
Lisa P.
The material is so soft and our little guy loves this sleep sack! We’ve used these since he was a newborn!
Julia L.
First of all, it shipped so fast! Second of all she is FINALLY falling asleep in her bassinet and staying asleep when I put her down. Without the sleep sack she would wake up IMMEDIATELY when I put her down. I’m so glad I found this! I definitely recommend
Mark S.
When we ordered the Zen Sac Classic not we were hopeful, but weren’t expecting drastic results. We have been pleasantly surprised by how well it has worked. It took one night for our 8-month old to acclimate, but has slept through night since. She was previously waking up 3-5 times a night. Couldn’t recommend it enough!
Hunter H.
My daughter loves it!
Sierra S.
We love these! I work at an early learning center and we ordered these for our infant rooms; big hit with the babies and their families. I order them now as gifts.

How much weight is in the Zen Sack™?
The Zen Sack features a self-contained Cuddle Pad™, which weighs just 30 grams (Small size) 60 grams (Medium size) and 90 grams (Large size and distributed across the chest).

What’s the difference between Classic, Premier, and Winter Zen Sack™ products?
The only difference between these Zen Sack products is the fabric used for construction. Classic Cotton is made from 100% breathable cotton. The Premier Bamboo is made from 70% rayon from bamboo for luxurious softness and 30% cotton for strength. Light-weight fabric, perfect for warmer climates. Bamboo is naturally anti-microbial and moisture wicking for dry, clean comfort. The Winter Cotton is made from 100% cotton and heavy poly-fiber filling. Our warmest option is perfect for cooler rooms or colder weather.
-
Is the Zen Sack safe for babies who roll over?
The Zen Sack was designed for rollers and tummy sleepers. It helps babies get longer, more peaceful sleep through all growth stages. The Cuddle Pad™ on the front of the Zen Sack 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 gently weighted center on baby's back for continuous comfort through the night.
Put sleep disruptions to bed with the Zen Sack™
Seamlessly transition from swaddling
When rolling starts, swaddling stops—and some babies miss their cozy swaddle. Prevent wakeups with the gently weighted Zen Sack: So soothing, but tummy sleeper safe.
Stop sleep regressions
Rolling, sitting up, teething: New milestones can mean sleep regressions. Add the gently weighted Zen Sack to your sleep routine to help create positive associations with bedtime.
Help baby sleep through the night
