Elizabeth H.
I was so nervous to stop swaddling because it was the only way my daughter would sleep. I thought it would take days or weeks for her to adjust to the weighted sleep sac but she fell right asleep the first time wearing it!! I wish I switched her to it sooner!
Alyssa N.
This works great! I was sceptical if this would work or not but was at the point of trying anything. My 4 month old was still only sleeping 1.5 hours at a time max and had never slept 4 hour. As soon as I put him to sleep in this, he started sleeping better! Now he is sleeping 3-4 hours at a time. Thank you! Well worth the cost and I'm starting to feel human again!
Brittany D.
I bought one and loved it so I bought another!
Anita M.
Quality is good, arrived ahead of schedule. My grandson sleeps more soundly in it as it keeps him cozy, warm and he feels I am just holding him.
Mallory E.
We love our Nested Bean! Our daughter was wiggling out of her sleep sack swaddle so we decided it was time for a change. The weighted chest gives her the comfort of the swaddle with the freedom of her arms. We are all getting excellent sleep!
Natasha R.
I love this sleeper in just three days my baby is sleeping through the night.
Tara M.
This sleep sack is the best! My baby may not be sleeping through the night, but I fully believe this sleep sack helps make the transition from my arms to the crib smooth every time!
Carly R.
I wish there were more small sizes available versus just 0-6 months. The looser sack my baby is just not a fan.
Brittany H.
I love this sleep sack! I bought my daughter one when she was 3 months old and the difference it made was amazing. Once she outgrew her first I bought her second and now she’s on her third and sleeps so well!! I will deff recommend this to any mom who’s struggling with more sleep.
bethany p.
The first night after getting the sack our little one slept amazing. Just last night which is maybe two weeks after purchasing the sack and a few days after purchasing the footie pajamas he slept 6-7 hours. We love these and would highly recommend them. We are definitely purchasing more!
Rebecca H.
I bought this hoping it would help my 7 month old sleep better. It’s really nice quality and super soft. It has convenient buttons over the shoulders and fully zips open for easy diaper changes. But as far as helping her sleep… I haven’t noticed any difference, unfortunately.
Jasmin B.
Love it! Helped my kiddo sleep great
Cristina D.
Love nested bean! We started with the zen one with our babe at 3 weeks because he hated being swaddled. Now we are using the sleep sacks and the material is so soft. We love it!
Rosa A.
Very please to have this handy swaddle. I wish they had much bigger sizes because my son is way to tall and is getting smaller for him.
Allison B.
The cotton material was thicker than I thought it would be and the sack itself is huge on my 8 month old. And I didn't see any real improvement in my son's sleep even after 2 weeks of consistent use.
Dana N.
Ok
Richel H.
It works!
Amanda L.
I have used nested bean sleep sacks for years and I recommend them to all moms looking for ways to improve there little ones sleep! The quality has always been outstanding.
Iveelyn R.
She loves it and sleeps through the night with it!
Serena J.
4th nested bean seep sack I’ve bought and it’s great as always! My daughter sleeps like a log in it!
Kristen B.
Absolutely love the Zen Sack! Our little one has transitioned really well from the Zen Swaddle.
Shelby F.
I was skeptical at first. My little one LOVED being swaddled and I was so nervous to transition. The first three nights were tough for her, but after that 12 HOURS of sleep since being in the nested bean. 12 hours for 2 weeks now and going strong. Plus she looks so cute in it too.
Rebecca H.
It’s nicely made,’and it’s a sleep sack so it serves its purpose. It unfortunately has
Not improved my little ones sleep.
Anand Kundan M.
This is the best sleep sack ever. I’m not sure how much the weighted serve it’s purpose but the intelligent design of wearable both front and back is genius. The fabric is super soft and remains the same after multiple washes. I do wish the product had some thinner versions for summer but overall it’s the best that I found after trying a lot of competitors.
brooke h.
We love it! Our daughter is 3 mo and we just switched from a swaddle. she was breaking out every night. We are so so thrilled to have this product!
Carrisa
We’ve used Nested Bean from the get go for our second baby starting with the swaddle and now the sleep sack. He has been the BEST sleeper. It truly does help me sleep better and when he does wake, if he’s not hungry, he is able to calmly and quietly soothe himself back to sleep. We now have 3 sacks; one to wear, one to wash if needed and one to spare (because blowouts have happened). I love the double zipper and that the bottom zipper can be covered with a snap. The shoulder snaps have to sizes which is also nice. My som is 18lbs at 4lbs and we use the medium size sack.
Mary D.
Absolute life saver. My daughter is 6 weeks old and the classic has made such a difference in her sleeping over the last 2 weeks of use. She’s sleeping longer and deeper, and keeps her at a comfortable temperature throughout the night. Normal swaddles weren’t working well because she “needs” her arms out, so the zen sack keeps her feeling safe but gives her her freedom. I never thought I would appreciate a baby product as much as I do.
Katlynn B.
My baby loves it and has slept amazing since we got it. It's lightweight enough that he's not too hot but definitely provides a barrier to keep him warm.
Megan S.
Love this! We started using this as a transition to get her out of a swaddle, and it’s been perfect. Now she’s rolling over immediately when we lay her down, so I’ve need putting it on her backwards so that the weight is on her back. It’s worked wonders so far!
Brooke T.
Great and well made product, however I don’t think it helped my colicky baby all that much.
Jayce G.
Amazing quality especially for the affordable price. Baby now knows the sleep sack means nap or bed time. Already a good sleeper but the sleep sack helps her fussier days and plus is adorable to see her in
Linda A.
I wished I would have discovered the sleep sack sooner, the first time I used this on my 7 month old grandson, I noticed an immediate calmness when he laid in my arms. He slept a solid 4 -1/2 hrs. the first night, where normally he would wake up 4-5 times. I expect his sleeping patterns to improve as we continue to use the sleep sack. I am a believer and I totally expect this product will continue to help our grandson get the long and solid sleep he needs and give his parents a much needed rest as well.
Lauren C.
Provides comfort to help my baby stay asleep. Less fussiness.
Kelly N.
Has definitely helped my son sleep better at night after being sick & getting out of his normal sleep routine. Will definitely purchase the biggest size as my son gets older
Kry S.
Love it! Arrived quick, box was a little damaged but product ok. Great quality and material. My baby used to toss and turn a lot. With the sack baby immediately fell in deep sleep and didn’t move a finger for 8 hours. We ended up waking her and she gave us the biggest smile when we did. <3
Only concern, sack has a BIG warning label on the outer side that I know can be removed but depending on how you cut it there will always be a part of it stitched. Wish they found a better placement for it.
Kayla K.
I’ve had it for a week and my child still is waking up every 2 hours.
The size they recommended is to big.
Emily M.
Love it

6 month old sleeps great in this
Catherine D.
Just stepped to the Zen Sack and love it. It truly seems to calm our baby and allow her to get a better night’s sleep. (And me too!)
Melanie B.
Little guy fell asleep so quickly! Thank you. He’s been sleeping through the night in his own crib
Kathleen H.
It’s excellent quality and my daughter loves her sleep sack. Every morning when I go get her she points to the part that’s weighted. Just part of our routine and don’t know what we would do without it!
Elizabeth C.
Unfortunately sleep has gotten significantly worse since we switched to this sack. Not sure if the sack is related or not. It looks nice. I just wish I could say it was helping.
Kennedy S.
The first night we didn’t notice much of a difference so I was skeptical, but I think that was more sleep regression related, because last night our little one didn’t make a peep! It also calms him down immediately if he’s crying. Definitely need to get another one as backup!
Geralyn D.
Helps sleep for new baby! Perfectly weighted and great fit around the top, button on and off and zipper at bottom for easy quick changes!
Cassie H.
We used this after transitioning our daughter out of her Merlin magic suit as she started to roll over. She likes the suit and is sleeping well in it
Heather E.
Transitioned my 9 week old into this sleep sack from swaddling and never looked back! Charli had no problems and woke up happy the next morning like she slept better than ever! Very happy I didn’t even have a transition phase.
Angelica L.
it did work all the way
Kara C.
I absolutely love the sleep sack! We started with the Zen One and when my daughter outgrew that, I knew I’d be sticking with Nestedbean and had to upgrade her to the sleep sack! Solid night sleep since 2 months old ♥️
Kelly V.
Great experience and fast delivery.
Michelle C.
Sometimes I think it helps, but more for naps than overnight. Not blown away by the results.
deborah n.
My Great Granddaughter loves this!!!! It has become her blanket now
K C.
Went from waking every 1 to 2 hours to sleeping 4 hour stretches!!
Jessenia D.
Love it’s design , but mostly how snuggly it fits my baby making her have a good night sleep+naps
Samantha C.
I love the design of the sack. Soft breathable fabric, zippers make night time changes easy, snaps make it easy for on and off. But did it change my sons sleeping habbits...no. he still sleeps preety much the same. Was hoping to get longer stretches but he is only 3 months old this week and we have been usuing thile sac a month. He never liked being swaddled so possibly wake ups are still due to his infant startle reflex and hunger.
carolyn m.
Bought it for my great grandson. It is being sent to him in the next few days.
Hali L.
my baby girl loves this sleep sack! and I love the material of it!
Loren M.
These boys sleep so much better with these sleep sacks !
Martina R.
Buy this!!! Our sweet little baby used to have such a hard time staying sleep. She was so easily startled. She started with the swaddle and quickly grew to dislike her arms being obstructed. This sleeper sack from Nested Bean keeps her warm and lets her feel safe and secure with the weighted chest but so free to move around! We love it!
Melissa C.
Love it! Helped my baby sleep throughout the night within 3 days!!!
Brianna R.
My LO doesn't seem to mind it but I wouldn't say she sleeps too much better yet
Tricia G.
The zen sack has been a great tool to help us transition out of the traditional swaddle. We would definitely recommend it and have already bought the next size up to have when we need it!
Kamee V.
I thought the zen sacks were okay. Didn’t make much if a difference for my babe and I thought the TOG 1 ran cold for the temperature range it was made for. Also, the return policy kinda sucks since you can’t return or exchange a product once the box is opened which makes no sense ! How could you even try the product to see if it’s good and works if you can’t open the box… and have the assurance that you can return or exchange the product… anyways, pretty disappointed.
Suzanne S.
Purchased for my grandskn
Ali M.
Love this sleep sack for my 6 month old. Plenty of room to grow. I wasn’t sure if it made a difference the first few nights but I really do think it does! My little guy is only waking up once a night compared to 3-4 times!
Mayra M.
I really remembered everyone having problems with baby not sleeping at night to buy this. My baby boy wouldn’t sleep more then 2 hours during the night. Now his sleeping up to 6. I am very pleased, now I can finally get some type of rest. Also when I see his tired cues during the day I put it on him and falls asleep for at least a good 2 hour nap. It’s truly amazing
Nikki O.
First night using it and my son’s sleep has already improved a lot! Looking forward to have a good night sleep tonight and many nights to come, highly recommend this sleep sac Thank you
Nicke B.
My 2 month old was waking multiple times during the night until we tried the Zen Sack. Now she’s only waking once every night. Everyone is well rested now and we’re all very happy.
Hope W.
The sack is very comfy and soft - but does not change my babies sleep habits in any way. I use it because I don’t feel safe leaving her with a blanket - but other than that security, she is still up just as much :)
Siya P.
My baby sleep so good
Karen K.
Parents said it was their favorite baby gift and really helps the baby sleep! We bought it for them after our kids told us how much they loved it for our grandson - and that they use it every night! This will always be my "go-to" baby gift from now on! KK, Kansas City
Mirla A.
My son loved it
Victoria c.
My daughter would only sleep 3 hours stretch at night time and now we’re up to 7 sometimes 8 hours.
Sheana A.
I love the idea of it because my 4 eeek old baby loves when my hand is on his chest but he won’t soothe completely because his arms are free.
Josie H.
We love the sleep sack! It makes my baby feel cuddled and makes put downs easy.
Holly
Once my baby was ready to transition out of the swaddle, I used the Merlin sleep suit to help calm the remaining morrow reflex while we waited for him to be ready for a true sleep sack. The first night in his nested bean he flipped to his tummy and sleep soundly all night. Now we always put the bean on his back and he sleeps so well. Just ordered the next size up!! Only thing is I wish they were longer in length so he could stay in it even longer.
Katie K.
I’ve been using the nested bean sleep sack since my daughter outgrew her swaddle and she loves it. She actually asks me to put it on her!
Daisy C.
I never leave reviews but I had to with the zen sack!! Day 2 of my 6 month old using the zen sack and can already see a difference in his night sleep! He is a wiggle worm and since using the sack he moves less at night.
Katie K.
She sleeps so well. Wakes once a night to feed and that is all.
Dejha B.
Highly reccomend ! My baby was sleeping through the night at first then started waking in the night so I hurried and got the nested bean and it worked the same day , love it
Savannah S.
My little girl is a rough sleeper. She fights naps like the plague, and my nights were so long. She was waking every 2-3 hours crying like crazy! Her daddy is in Iraq so I was desperate for help. A mom friend of mine recommended the nested bean sack and since it arrived I’ve finally been able to get some rest and my girl has too.
Kayla B.
I was skeptical at first. I bought this for my son at around 6 months. He used to fall a sleep in his swing so I was worried he would never transition to his bed. By night 3 I was ready to give up and held on to night 4 and he finally slept better! He wakes up maybe once or twice, but he used to wake constantly so I am so thankful for this product!
Lindsay R.
As soon as we would lay our son down he would wake up, so we started using the Zen Sack when he was 4 weeks old, and it’s been a game changer. He still wakes to eat, but I can usually lay him down after and he stays sleeping. I can even lay him down in the sleep sack when he is drowsy and he will fall asleep on his own.
Raynah T.
When our daughter was 4 months old she started waking 3-6 times at night, every night, until she was 15 months old. We had tried everything to try helping her sleep, but nothing made a difference. Finally we decided to try the Zen sleep sack. We were skeptical at first, but our baby girl was sleeping through the night the very first night she wore her sleep sack. It was such a huge relief that I nearly cried. It’s been a week and the difference this product has made us almost unbelievable. I can’t tell you how much it means to us that we are all finally getting our much needed sleep. My only regret is that we didn’t try Zen sleep sack sooner!
Chau T.
Our baby loves it. It calms her and puts her to sleep within minutes. It has worked great and I hope it continues to do so!
Maria B.
My baby was waking up twice at night and as soon as I started using it he is only waking up once. I I thought that this was a scam and that it wasn’t gonna work but I am in love and I’m already recommending it to my friend that is soon having her baby!!!
Suet yen S.
My baby loves this sleep sack! He is 3 months old and has done his third 8-10H stretch in his nested bean.
Donovan S.
Good transitional sack. High quality material.
Casey D.
This is out 8th sleepsack purchase. Our son is 3.5 and has well outgrown wearing a sleepsack but these have become his “cozies.” He drags them around like a blanket everywhere he goes and has to have one to sleep! Great product and they truly hold up well! We still have his originals!
Elisha T.
Happy with our purchase!
Bergen L.
It’s beginning to work. We had it for almost two weeks and my little is adjusting to it .. he still wakes up at night however he’s getting used to self soothing and laying in bed once he wakes up.
Alexandria B.
This sleep sack is just ok. Definitely works to keep baby warm at night while not being too hot and uncomfortable but I did not see a change in sleep at all after 3 weeks of use.
Brittany S.
My son absolutely loves his sleep sack. I didn't help with the sleeplessness throughout the night, but he sure falls asleep quicker wearing it.
Anabolena D.
My son loved the sleep sack and it looks so adorable on him.
Courtney
We’ll never use another sleep sack. Nested Bean is the best. It has grown with our little boy and he loves getting into it each night.
Mingma S.
My baby loves it. Sleeps much better.
Kody P.
Bought this for my son whom is 4 months old and was waking up on and off through out the night. After purchasing and trying it out. I guess I would say it somewhat helped. He still wakes up through out the night. It helps with comfort more than anything
Julie M.
My baby loves his!!
Carmelino A.
Love it
Laura S.
We LOVE the Nested Bean sleep sacks! So soft and functional with the snaps and zippers. The quality compares to $60 sleep sacks for half the cost! I tried a cheaper ($23) popular brand and the fabric and functionality doesn’t compare at all. Don’t try to save a buck, just buy these and you won’t regret it.
We started out with the medium size and now just transitioned to large. My son is 22 pounds and 29 inches long - it’s a little big now but he will grow into it perfectly in coming weeks. THANK YOU NESTED BEAN!
Elizabeth H.
I was so nervous to stop swaddling because it was the only way my daughter would sleep. I thought it would take days or weeks for her to adjust to the weighted sleep sac but she fell right asleep the first time wearing it!! I wish I switched her to it sooner!
Alyssa N.
This works great! I was sceptical if this would work or not but was at the point of trying anything. My 4 month old was still only sleeping 1.5 hours at a time max and had never slept 4 hour. As soon as I put him to sleep in this, he started sleeping better! Now he is sleeping 3-4 hours at a time. Thank you! Well worth the cost and I'm starting to feel human again!
Brittany D.
I bought one and loved it so I bought another!
Anita M.
Quality is good, arrived ahead of schedule. My grandson sleeps more soundly in it as it keeps him cozy, warm and he feels I am just holding him.
Mallory E.
We love our Nested Bean! Our daughter was wiggling out of her sleep sack swaddle so we decided it was time for a change. The weighted chest gives her the comfort of the swaddle with the freedom of her arms. We are all getting excellent sleep!
Natasha R.
I love this sleeper in just three days my baby is sleeping through the night.
Tara M.
This sleep sack is the best! My baby may not be sleeping through the night, but I fully believe this sleep sack helps make the transition from my arms to the crib smooth every time!
Carly R.
I wish there were more small sizes available versus just 0-6 months. The looser sack my baby is just not a fan.
Brittany H.
I love this sleep sack! I bought my daughter one when she was 3 months old and the difference it made was amazing. Once she outgrew her first I bought her second and now she’s on her third and sleeps so well!! I will deff recommend this to any mom who’s struggling with more sleep.
bethany p.
The first night after getting the sack our little one slept amazing. Just last night which is maybe two weeks after purchasing the sack and a few days after purchasing the footie pajamas he slept 6-7 hours. We love these and would highly recommend them. We are definitely purchasing more!
Rebecca H.
I bought this hoping it would help my 7 month old sleep better. It’s really nice quality and super soft. It has convenient buttons over the shoulders and fully zips open for easy diaper changes. But as far as helping her sleep… I haven’t noticed any difference, unfortunately.
Jasmin B.
Love it! Helped my kiddo sleep great
Cristina D.
Love nested bean! We started with the zen one with our babe at 3 weeks because he hated being swaddled. Now we are using the sleep sacks and the material is so soft. We love it!
Rosa A.
Very please to have this handy swaddle. I wish they had much bigger sizes because my son is way to tall and is getting smaller for him.
Allison B.
The cotton material was thicker than I thought it would be and the sack itself is huge on my 8 month old. And I didn't see any real improvement in my son's sleep even after 2 weeks of consistent use.
Dana N.
Ok
Richel H.
It works!
Amanda L.
I have used nested bean sleep sacks for years and I recommend them to all moms looking for ways to improve there little ones sleep! The quality has always been outstanding.

She loves it and sleeps through the night with it!
Serena J.
4th nested bean seep sack I’ve bought and it’s great as always! My daughter sleeps like a log in it!
Kristen B.
Absolutely love the Zen Sack! Our little one has transitioned really well from the Zen Swaddle.
Shelby F.
I was skeptical at first. My little one LOVED being swaddled and I was so nervous to transition. The first three nights were tough for her, but after that 12 HOURS of sleep since being in the nested bean. 12 hours for 2 weeks now and going strong. Plus she looks so cute in it too.
Rebecca H.
It’s nicely made,’and it’s a sleep sack so it serves its purpose. It unfortunately has
Not improved my little ones sleep.
Anand Kundan M.
This is the best sleep sack ever. I’m not sure how much the weighted serve it’s purpose but the intelligent design of wearable both front and back is genius. The fabric is super soft and remains the same after multiple washes. I do wish the product had some thinner versions for summer but overall it’s the best that I found after trying a lot of competitors.
brooke h.
We love it! Our daughter is 3 mo and we just switched from a swaddle. she was breaking out every night. We are so so thrilled to have this product!
Carrisa
We’ve used Nested Bean from the get go for our second baby starting with the swaddle and now the sleep sack. He has been the BEST sleeper. It truly does help me sleep better and when he does wake, if he’s not hungry, he is able to calmly and quietly soothe himself back to sleep. We now have 3 sacks; one to wear, one to wash if needed and one to spare (because blowouts have happened). I love the double zipper and that the bottom zipper can be covered with a snap. The shoulder snaps have to sizes which is also nice. My som is 18lbs at 4lbs and we use the medium size sack.
Mary D.
Absolute life saver. My daughter is 6 weeks old and the classic has made such a difference in her sleeping over the last 2 weeks of use. She’s sleeping longer and deeper, and keeps her at a comfortable temperature throughout the night. Normal swaddles weren’t working well because she “needs” her arms out, so the zen sack keeps her feeling safe but gives her her freedom. I never thought I would appreciate a baby product as much as I do.
Katlynn B.
My baby loves it and has slept amazing since we got it. It's lightweight enough that he's not too hot but definitely provides a barrier to keep him warm.
Megan S.
Love this! We started using this as a transition to get her out of a swaddle, and it’s been perfect. Now she’s rolling over immediately when we lay her down, so I’ve need putting it on her backwards so that the weight is on her back. It’s worked wonders so far!
Brooke T.
Great and well made product, however I don’t think it helped my colicky baby all that much.
Jayce G.
Amazing quality especially for the affordable price. Baby now knows the sleep sack means nap or bed time. Already a good sleeper but the sleep sack helps her fussier days and plus is adorable to see her in
Linda A.
I wished I would have discovered the sleep sack sooner, the first time I used this on my 7 month old grandson, I noticed an immediate calmness when he laid in my arms. He slept a solid 4 -1/2 hrs. the first night, where normally he would wake up 4-5 times. I expect his sleeping patterns to improve as we continue to use the sleep sack. I am a believer and I totally expect this product will continue to help our grandson get the long and solid sleep he needs and give his parents a much needed rest as well.
Lauren C.
Provides comfort to help my baby stay asleep. Less fussiness.
Kelly N.
Has definitely helped my son sleep better at night after being sick & getting out of his normal sleep routine. Will definitely purchase the biggest size as my son gets older
Kry S.
Love it! Arrived quick, box was a little damaged but product ok. Great quality and material. My baby used to toss and turn a lot. With the sack baby immediately fell in deep sleep and didn’t move a finger for 8 hours. We ended up waking her and she gave us the biggest smile when we did. <3
Only concern, sack has a BIG warning label on the outer side that I know can be removed but depending on how you cut it there will always be a part of it stitched. Wish they found a better placement for it.
Kayla K.
I’ve had it for a week and my child still is waking up every 2 hours.
The size they recommended is to big.

Just stepped to the Zen Sack and love it. It truly seems to calm our baby and allow her to get a better night’s sleep. (And me too!)
Melanie B.
Little guy fell asleep so quickly! Thank you. He’s been sleeping through the night in his own crib
Kathleen H.
It’s excellent quality and my daughter loves her sleep sack. Every morning when I go get her she points to the part that’s weighted. Just part of our routine and don’t know what we would do without it!
Elizabeth C.
Unfortunately sleep has gotten significantly worse since we switched to this sack. Not sure if the sack is related or not. It looks nice. I just wish I could say it was helping.
Kennedy S.
The first night we didn’t notice much of a difference so I was skeptical, but I think that was more sleep regression related, because last night our little one didn’t make a peep! It also calms him down immediately if he’s crying. Definitely need to get another one as backup!
Geralyn D.
Helps sleep for new baby! Perfectly weighted and great fit around the top, button on and off and zipper at bottom for easy quick changes!
Cassie H.
We used this after transitioning our daughter out of her Merlin magic suit as she started to roll over. She likes the suit and is sleeping well in it
Heather E.
Transitioned my 9 week old into this sleep sack from swaddling and never looked back! Charli had no problems and woke up happy the next morning like she slept better than ever! Very happy I didn’t even have a transition phase.
Angelica L.
it did work all the way
Kara C.
I absolutely love the sleep sack! We started with the Zen One and when my daughter outgrew that, I knew I’d be sticking with Nestedbean and had to upgrade her to the sleep sack! Solid night sleep since 2 months old ♥️

Great experience and fast delivery.
Michelle C.
Sometimes I think it helps, but more for naps than overnight. Not blown away by the results.

My Great Granddaughter loves this!!!! It has become her blanket now
K C.
Went from waking every 1 to 2 hours to sleeping 4 hour stretches!!
Jessenia D.
Love it’s design , but mostly how snuggly it fits my baby making her have a good night sleep+naps
Samantha C.
I love the design of the sack. Soft breathable fabric, zippers make night time changes easy, snaps make it easy for on and off. But did it change my sons sleeping habbits...no. he still sleeps preety much the same. Was hoping to get longer stretches but he is only 3 months old this week and we have been usuing thile sac a month. He never liked being swaddled so possibly wake ups are still due to his infant startle reflex and hunger.
carolyn m.
Bought it for my great grandson. It is being sent to him in the next few days.
Hali L.
my baby girl loves this sleep sack! and I love the material of it!
Loren M.
These boys sleep so much better with these sleep sacks !
Martina R.
Buy this!!! Our sweet little baby used to have such a hard time staying sleep. She was so easily startled. She started with the swaddle and quickly grew to dislike her arms being obstructed. This sleeper sack from Nested Bean keeps her warm and lets her feel safe and secure with the weighted chest but so free to move around! We love it!
Melissa C.
Love it! Helped my baby sleep throughout the night within 3 days!!!

The zen sack has been a great tool to help us transition out of the traditional swaddle. We would definitely recommend it and have already bought the next size up to have when we need it!

I thought the zen sacks were okay. Didn’t make much if a difference for my babe and I thought the TOG 1 ran cold for the temperature range it was made for. Also, the return policy kinda sucks since you can’t return or exchange a product once the box is opened which makes no sense ! How could you even try the product to see if it’s good and works if you can’t open the box… and have the assurance that you can return or exchange the product… anyways, pretty disappointed.

Love this sleep sack for my 6 month old. Plenty of room to grow. I wasn’t sure if it made a difference the first few nights but I really do think it does! My little guy is only waking up once a night compared to 3-4 times!

I really remembered everyone having problems with baby not sleeping at night to buy this. My baby boy wouldn’t sleep more then 2 hours during the night. Now his sleeping up to 6. I am very pleased, now I can finally get some type of rest. Also when I see his tired cues during the day I put it on him and falls asleep for at least a good 2 hour nap. It’s truly amazing

My 2 month old was waking multiple times during the night until we tried the Zen Sack. Now she’s only waking once every night. Everyone is well rested now and we’re all very happy.

The sack is very comfy and soft - but does not change my babies sleep habits in any way. I use it because I don’t feel safe leaving her with a blanket - but other than that security, she is still up just as much :)

My baby sleep so good

Parents said it was their favorite baby gift and really helps the baby sleep! We bought it for them after our kids told us how much they loved it for our grandson - and that they use it every night! This will always be my "go-to" baby gift from now on! KK, Kansas City

My son loved it

My daughter would only sleep 3 hours stretch at night time and now we’re up to 7 sometimes 8 hours.
Sheana A.
I love the idea of it because my 4 eeek old baby loves when my hand is on his chest but he won’t soothe completely because his arms are free.

We love the sleep sack! It makes my baby feel cuddled and makes put downs easy.

Once my baby was ready to transition out of the swaddle, I used the Merlin sleep suit to help calm the remaining morrow reflex while we waited for him to be ready for a true sleep sack. The first night in his nested bean he flipped to his tummy and sleep soundly all night. Now we always put the bean on his back and he sleeps so well. Just ordered the next size up!! Only thing is I wish they were longer in length so he could stay in it even longer.

I’ve been using the nested bean sleep sack since my daughter outgrew her swaddle and she loves it. She actually asks me to put it on her!
Daisy C.
I never leave reviews but I had to with the zen sack!! Day 2 of my 6 month old using the zen sack and can already see a difference in his night sleep! He is a wiggle worm and since using the sack he moves less at night.
Katie K.
She sleeps so well. Wakes once a night to feed and that is all.
Dejha B.
Highly reccomend ! My baby was sleeping through the night at first then started waking in the night so I hurried and got the nested bean and it worked the same day , love it
Savannah S.
My little girl is a rough sleeper. She fights naps like the plague, and my nights were so long. She was waking every 2-3 hours crying like crazy! Her daddy is in Iraq so I was desperate for help. A mom friend of mine recommended the nested bean sack and since it arrived I’ve finally been able to get some rest and my girl has too.
Kayla B.
I was skeptical at first. I bought this for my son at around 6 months. He used to fall a sleep in his swing so I was worried he would never transition to his bed. By night 3 I was ready to give up and held on to night 4 and he finally slept better! He wakes up maybe once or twice, but he used to wake constantly so I am so thankful for this product!
Lindsay R.
As soon as we would lay our son down he would wake up, so we started using the Zen Sack when he was 4 weeks old, and it’s been a game changer. He still wakes to eat, but I can usually lay him down after and he stays sleeping. I can even lay him down in the sleep sack when he is drowsy and he will fall asleep on his own.

When our daughter was 4 months old she started waking 3-6 times at night, every night, until she was 15 months old. We had tried everything to try helping her sleep, but nothing made a difference. Finally we decided to try the Zen sleep sack. We were skeptical at first, but our baby girl was sleeping through the night the very first night she wore her sleep sack. It was such a huge relief that I nearly cried. It’s been a week and the difference this product has made us almost unbelievable. I can’t tell you how much it means to us that we are all finally getting our much needed sleep. My only regret is that we didn’t try Zen sleep sack sooner!
Chau T.
Our baby loves it. It calms her and puts her to sleep within minutes. It has worked great and I hope it continues to do so!
Maria B.
My baby was waking up twice at night and as soon as I started using it he is only waking up once. I I thought that this was a scam and that it wasn’t gonna work but I am in love and I’m already recommending it to my friend that is soon having her baby!!!
Suet yen S.
My baby loves this sleep sack! He is 3 months old and has done his third 8-10H stretch in his nested bean.
Donovan S.
Good transitional sack. High quality material.
Casey D.
This is out 8th sleepsack purchase. Our son is 3.5 and has well outgrown wearing a sleepsack but these have become his “cozies.” He drags them around like a blanket everywhere he goes and has to have one to sleep! Great product and they truly hold up well! We still have his originals!
Elisha T.
Happy with our purchase!
Bergen L.
It’s beginning to work. We had it for almost two weeks and my little is adjusting to it .. he still wakes up at night however he’s getting used to self soothing and laying in bed once he wakes up.
Alexandria B.
This sleep sack is just ok. Definitely works to keep baby warm at night while not being too hot and uncomfortable but I did not see a change in sleep at all after 3 weeks of use.
Brittany S.
My son absolutely loves his sleep sack. I didn't help with the sleeplessness throughout the night, but he sure falls asleep quicker wearing it.
Anabolena D.
My son loved the sleep sack and it looks so adorable on him.

We’ll never use another sleep sack. Nested Bean is the best. It has grown with our little boy and he loves getting into it each night.
Mingma S.
My baby loves it. Sleeps much better.
Kody P.
Bought this for my son whom is 4 months old and was waking up on and off through out the night. After purchasing and trying it out. I guess I would say it somewhat helped. He still wakes up through out the night. It helps with comfort more than anything
Julie M.
My baby loves his!!
Carmelino A.
Love it

We LOVE the Nested Bean sleep sacks! So soft and functional with the snaps and zippers. The quality compares to $60 sleep sacks for half the cost! I tried a cheaper ($23) popular brand and the fabric and functionality doesn’t compare at all. Don’t try to save a buck, just buy these and you won’t regret it.
We started out with the medium size and now just transitioned to large. My son is 22 pounds and 29 inches long - it’s a little big now but he will grow into it perfectly in coming weeks. THANK YOU NESTED BEAN!
Frequently asked questions
-
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). Our products 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.
-
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
Nighttime wakeups? The gently weighted Zen Sack is so comforting, it helps babies self-soothe—so they fall back to sleep on their own.
