I absolutely believe this helps my baby sleep better at night. I didn’t use one with our first and wish we would have.
Abby R.
It’s a functional sleep sack. I can’t say that it’s helped her sleep any better though.
Jennifer R.
My son has been using nested bean since 1 month, I find comfort in knowing I don’t have to put a blanket on him & worry about him being cold or him getting tangled in blanket while sleeping. Invest in your little ones! He also sleeps all night with it 10/10
Karynn M.
Very high quality and fits perfectly. This is our 5th bean and does not disappoint
Erica K.
Our little one did not sleep well at all. We were trying everything! Finally my MIL found this weighted sleep sack and it was a game changer! Once he was out of the swaddle we went with Nested Bean and won’t go back! So glad they have these up to 24 months. Wonderful product, high quality, would recommend for everyone!
Colleen M.
We were struggling to get my 1 year old to sleep past 4 am. I thought maybe he was getting cold and needed some cozy snuggles. These have been the perfect addition to our routine and sleep is going so well!
Avery K.
We love it! We went from sleeping 4 hours to sleeping 7-8 hours!
Brittany P.
Love our sleep sack and nested bean has the best customer service! We ordered the wrong size and they sent us the right one at no charge! So grateful for this to help our little one sleep so mommy & daddy can get some rest & function too :)
Traci H.
Love that it is lighter weight - perfect with a sleeper during winter months! Who does not love a good sleeping babe!
Puja P.
We've been a fan since we bought the 6-15 month sleep sack. Hopefully baby girl doesn't get too tall! The last one only worked til she hit 12 months and then she outgrew it. Very breathable and lightweight and she loves sleeping in it! Only reason for the 4 stars is how long I was able to use it for her.
Brinna C.
My baby has never slept better!! I’m much more at ease knowing my baby is comfortable and happy!
ash
great
Jannette C.
The nestedbean zen sack works wonders!! My baby boy is about to be 3 months next week and this is the first night he has slept over 9 hours Not to mention the sleep sack is super soft and just so cute!
Brenda F.
She sleeps all night.
It’s super easy to change her at night and keeps her warm!
Lauren R.
Love this product
Cameron H.
As soon as I put the Zen One on my 2 week old he instantly went to sleep. Instantly! It was amazing and he loves having his arms by his face, so the fact that he can have his arms out is a plus. I really think he likes the weighted part too, he loves being held. I will definitely be buying more!
Yvonne O.
Our baby loved her sleep sack . It gives her the freedom to move her arms and the comfort she is use to. We chose the winter style and love that it keeps her nice and warm .
Marianni L.
Love it! my 4 month old is going through sleep regression and this was a life saver. Mommy and daddy can now get some sleep and babe sleeps through the night !
Carla K.
Our little girl loves her zen sack! It is so soft and has a good bit of length so she can definitely grow into it. It has enough “weight” for her to have that feeling of our hands on her chest to settle her to sleep but light enough that she has no problem rolling from back to belly or vice versa. Biggest difference I’ve seen is during nap time, it used to be hard to get her to take naps in her crib but now settles pretty quickly. Highly recommend!
Amber W.
We transitioned from swaddle to nested bean at 2.5 months since our little lady likes to sleep on her side. They’re so soft and cozy. She’s been sleeping a full 8-10 hours at night now with her arms free!
Linda E.
First use was for a nap. She slept 2 1/2 hours! This was unusual for her! The night has not been as successful but we are hopeful.
Katie W.
Did not provide better sleep as advertised and shipping took longer than expected. When reaching out to customer service they were able to provide no additional support. For 10 days our tracking info never changed then one day the product randomly showed up after I had purchased something different. Very disappointed with the customer service support and shipping of the product.
Kasi B.
We absolutely love the nested bean for our 4 month old.
Autumn S.
We use it every night!
Elena M.
We love our gently weighted blanket!! Our baby loves it too. She seems to be sleeping much better than usual. We’re really happy
Tiffany S.
Absolutely love these sleep sacks.
Andrea G.
Didn’t really work for us. Very cute, well made and in theory is a wonderful idea. But my babe didn’t go for it. Tried it for a few days and nothing. Will maybe try again..
Natalie G.
My son wouldn’t sleep through the night and would wake up a bunch now he sleeps through the night and we’re finally getting some sleep too. He’s a tummy sleeper so with it being reversible it’s amazing
Gina P.
Love it
Sarah H.
This is great! Our baby loves it.
Jesse
This is the best sleeper I have tried yet! Just bought more!!
Kristin B.
I’ve always used sleep sacks for my son (swaddle sacks when he was a newborn) and I thought this would help him sleep better through his teething/9 month sleep regression but I haven’t really noticed much of a difference. The quality of the sleep sack is great. I love the material and how it’s designed. I just wish it helped my son sleep better.
Lukas H.
Can’t wait till our baby is older so we can use this product. Looks super soft and comfy. Love the color.
William M.
Excellent product!
Andrea C.
I have been using it on my 4-month-old and I have not seen any improvement on his sleep :( disappointed
Megan V.
Nestedbean is an AMAZING company. A pet ruined 3 of our zen sacks and they sent a free replacement. Customer service is top notch and the product actually works! Better sleep in 1-3 nights with both babies!
Thank you!
Courtney H.
Nested bean is my go-to baby shower gift because our boys LOVED them! We have great belly sleepers and the weight is perfect on their back!
Melissa D.
Absolutely love this sac. My little one definitely sleeps more comfortably. Will be buying a second one. Material is soft and holds up in wash. Two zippers for easy changing which is great! Great addition to our nightly and nap time routine.
Hilary K.
I love nested bean sleep sacks! They are nicely made, and keep my little guy cozy!

Ashlynn M.
Fast shipping and great product
Danielle A.
The quality wasn't exactly what I expected, for $40, but it's fine. It didn't improve my baby's sleeping at all. Not too impressed, overall.
Michele H.
I really love these sleep sacks for my little one. She started in the Zen One Classic from about 2 mo to 6 mo, which completely changed her sleep within a few days. Then I purchased the Zen Sack. I really love how soft and cuddly feeling the front is and that it will last her until about 15 mo. It was an easy transition out of the swaddles sack and she can sleep on her stomach safely as well. She only had a minor disruption between sacks and is back to sleeping peacefully.
Gregory W.
It's a high quality product and I'm happy with the way it's made, how it feels, etc. My daughter sleeps in it every night but she's not necessarily sleeping through the night. I've given it about 2 weeks and very little difference in her sleep. It's all good. We tried another weighted sleep sack prior to this with no success so I wasn't expecting much. I wouldn't stop anyone from buying this. If it works for your child then that's awesome! And even if it doesn't work then it's still a high quality sleep sack for your child to sleep in.
Janet R.
Our 6 week old was struggling to stay asleep at night. I'm a huge fan of my weighted blanket so I wanted to give this a try for my girl. She has been sleeping 7 hours straight a night so far! She seems to love it!
olha k.
The best sleeping sack for us. Very good quality, soft cotton, nice color selection to choose from
Davida R.
My 4.5 month old son went from waking every 2-3 hours to sleeping 11 hours straight!
Kourtney S.
Had it for a couple weeks now and haven’t really noticed my daughter sleeping any better than before. I like that’s it’s a nice material and light but was hoping so see more of a difference.
Madison K.
It’s okay! I wouldn’t say that she slept better in 1-3 nights. She still doesn’t sleep through the night like all the other reviews state. She wakes up just as often to nurse back to sleep. I do think she wakes up in the middle of the night more peacefully and isn't immediately bursting into tears. I would buy another but I wouldn’t get your hopes up on the immediate change in sleep behavior!
Alexandria W.
We have used this sleep sack for about 6 months and love it! It's part of our bedtime routine and our daughter knows when we get it out that it's time for bed.
Amanda H.
Highly recommend these sleep sacs! We use them every nap and night for sleep and they keep our babe’s temperature correct through summer and so far through this winter. I’m only having this one babe, so I’ll be gifting these for eternity!
This seems like a crazy review, but for reals; these things are amazing!
Amanda H.
We LOVE these sleep sacs! Seriously, they are amazing. I read recently that they can help with the routine of nap or bedtime and it totally works for our babe. As soon as we put her in it she starts to calm herself down and goes to sleep within an average of 5 minutes, without any fussiness or crying (except on the super rare occasion that’s usually unrelated).
Holly H.
Best baby shower gifts ever. I buy one for everyone expecting
Tanna H.
She loves having her arms out so we struggled to find the right swaddle but once we tried nested bean she slept so well! 5-7 hours a night!
Kathy B.
Nested Bean is one if the key ingredients to having a Great Little Sleeper! I’m a grandmother who wishes we’d had these 30 years ago. Great quality, pricing and sleep results - love this product!
Lindsey S.
Great
Stephanie K.
This is our 2nd nested bean sack! We had struggled with getting our then 4 month old to sleep longer than 2 hours and moved to her room. The first night she slept 4 hours straight, not a peep, in her own room! The sleep sacks make such a difference in how much and the quality of sleep our little one gets. I recommend them to everyone!!
Yudith R.
I find that my babi sleeps the same with or without it. Sometimes maybe even better without it. There are nights that she seems uncomfortable and I remove it then she falls asleep fine.
Mel M.
I feel like it took about 1-2 nights for my baby to be able to put himself to sleep. When he gets up for his midnight feeding it only takes a few mins to get him back asleep and he usually stays asleep. Only times he wakes up is when he wants his pacifier. But that’s rare now. This was a game changer for us!
Shawnee H.
Baby boy loves it and feels so comforted in this!
Ana F.
I can't tell if it's luck, but we got our sleep sack 2 days ago and my baby's sleep has substantially improved. Her naps are now over 1h long and she is able to resettle by herself in the meantime, which she wasn't doing before. I'm a fan! It's also super comfy and she seems to love being in it. I got the winter version and if things continue to be this amazing, I'll be purchasing the lighter versions for the spring/summer.
Annie G.
This worked really well for my little one. It did take about 2 days for her to get used to but by the third night she was sleeping better. Consistency is key and every night when I put her in her sack she knows it’s bedtime and looks forward to the snuggling into the sack.
Ashley S.
We absolutely love our sleep sack! I wish we would have purchased one before now. Our baby girl was not sleeping past 40-45 minute mark for anything. Last night she slept from 930p-230a. Talk about refreshed! I woke up in a panic because she slept so good. Mama isn't use to that. We also appreciated the quality of the fabric, it is so soft.
Jenniffer R.
Good
Veronica S.
She sleeps a bit better with the weight.
Elayne D.
He loves it! It feels loving and comfy to him!
Jessica C.
I have the regular sleep sack and the winter sleep sack and I had doubts but took a leak y of faith in desperation. These truly work! First night using them and my 3 month old slept 8 hours. 2-4 night he slept 8 hours, 5th night 6 hours and last night he slept 9 hours! I still can't beleive it. It's a miracle worker. He was sleeping 2 to 3 hours a night and I was losing my mind bc I work. This is a life saver. We are eternally grateful!
Tina M.
My daughter didn’t sleep for awhile at one time. She would sleep 5/10mins and back awake! At night time waking up in between her 2.5 hour sleep. When I started using the sack I was shocked how amazing it made a difference she now sleeps 3 hours before she wakes if I don’t put her in it at night she is constantly waking up! ❤️ Highly recommend!!!!!
Stephanie E.
I wasn’t sure if it worked because my daughter rolls around a lot in her sleep, switching to all kinds of positions, so I thought it would be uncomfortable and cumbersome, but when I switched back to her old zippered blanket, she wouldn’t let me put her in the crib for 2 nights in a row. To see if the nested bean really worked, or helped, I switched her back to it and she went back to sleeping in her crib! So it really does seem to work! Would be 5 stars if the shoulders and arm openings were a little bit bigger or softer/flexible. Otherwise seems like a great product and I’m pleased. Price point is also great. I love that you can wash and dry it normally! Most of her other bags are more expensive and require a lot of care.
Izabella B.
My son sleeps so well in these sacks!
Carly E.
I bought this for my 5 month old granddaughter, and she loves it. The print is adorable and the weight is perfect for settling her to sleep. She tends to sleep warm, so the light weight fabric is perfect.
Megan R.
We live in Iowa and it is plenty warm for our sweet babe at night! We transitioned from a halo swaddle to the sleep sack and he sleeps great!
Jessica S.
Our son falls asleep easily, but usually wakes up every 3-4 hours during the night. The first night he wore the sleep sack he slept for 6 hours straight! Thought it was a fluke but tried it a different night and same outcome. It’s also made it easier to calm him into a nap during the day by mimicking the weighted egg with my hand on his chest. Will probably buy a second one!
Lee R.
Our 2 month old baby girl Wrennlee loves her new zen sack!!
Alejandra P.
Our little chunkster loveeesss her nested bean sack. This saved our sanity through the nights because the moment we put it on her she inmmediately falls asleep! It's like she knows it comforts her and it makes her feel cozy and safe. 10/10 get yourself a sack!!!! It's worth it!!
Courtney F.
Our tummy sleeper loves to wear hers backwards!
Jeana P.
The Zen Sack is ok. I wish to say it helped my baby sleep better but it didn’t do anything. Baby sleeps the same with or without the sack. Maybe it’s just him, always been anything but a good sleeper. However, the material is nice and it feels comfortable for him compare to other sleep sacks.
Kayla S.
Best cuddle
Kathleen P.
Bought it for my granddaughter and mom loves it!!!!
Jamie D.
My son’s favorite sleep sack.
Kendra R.
Perfect transition from a halo!
Courtney W.
The only mistake I made was not buying more than one! This momma is in love with this sleep sack! My daughter slept through the night for the first time in 6 months. And she still does almost a whole month later. It is washer and dryer friendly (trust! we've had plenty of accidents) I will be buying another soon! 10/10 recommend!
Rocio B.
My baby it’s kinda okay with it, she likes to move a lot so she wakes her self up haha
Karen S.
I purchased this for my grandson and it really seems to be working well
Tania R.
The sleep sack is okay. We have been using it in our transition to the crib but she still cries as she's a cuddler. The onesie is better but she is already outgrowing both.
Ann B.
My baby sleeps 5-6 hour stretches thanks to the nested bean sleep sack! Highly recommend for those sleep training their babies. Can’t wait to buy more!
Hanna C.
The Nested Bean sleep sack seems to help my baby soothe himself back to sleep when he rolls over in the middle of the night. We've bought the next size up because we liked his infant sleep sack so much!
Brooke S.
Love nested bean! We have used the newborn sacks and now this sleep sack! My baby wears it backwards because he is a stomach sleeper!
Brooke S.
My baby loves his sleep sack! He wears it backwards because he is a stomach sleeper! Only sleep sack we use!
Cory J.
I had high hopes for this sleep sack since my baby only sleep 2-3 hours at a time. I really haven’t noticed much a difference. I went without it for a few nights to see and I guess it helps her sleep a little better not much.
Lauren S.
Love this sleepsack. Light enough so it’s comfortable & not too hot for baby but cozy enough to soothe for bedtime.
Toni B.
This sleep sack is so nice and cozy!! It is made very high quality! I didn’t notice that the weighted chest made much difference with my baby but he is going through a sleep regression and maybe some other things right now as well. But again I love the quality and I know my baby is warm and cozy in a blanket that can’t hurt him ❤️ Thank you Nested Bean!
Sara S.
Absolutely love this sleep sack. The prints are gorgeous, great material and they wash well. We out ours on our girl backwards because she rolls to her tummy to sleep. We will be buying another couple for the next size up.
Sierra D.
My 6 week old was getting over the swaddle as he didn’t like being restrained! This makes him feel secure with having his hands out & we both like that
Diana S.
I was hoping that my 6 month old baby find real comfort and be able t sleep all night, however this was not the case. Although it didn’t work I am happy with my purchase, I Love how soft it is and easy to use during diaper changes ( night time .
Kim S.
Doesn’t help her sleep but love that it keeps her snug and warm!
Krystle G.
My daughter loves her sleep sacks! She started with the swaddle one then outgrew it so we switched to the swaddle and she gets excited every night when we put it on her because she knows it’s bedtime! Best sleep sack hands down!
Amber C.
My mother in law bought me a nested bean sleep sack from a garage sale. He was starting to get too big for his swaddle and I had already tried the “magic suit”. So I thought, “let’s try this tonight and see how he likes it.” He loved it! He’s grown out of the one that was given to me so I went ahead and bought 3 new ones that were bigger in size. Thank you so much Nested Bean for making a product that my baby loves and giving this momma some extra rest.
Cassandra P.
Doesn’t live up to the hype. My son doesn’t mind it, but it doesn’t make a difference in his sleeping at all.
Tobie B.
I never thought of using sleep sack because I always thought it won't work but I guess wrong. My baby can sleep longer than before. I can finally enjoy my sleep. I actually love it
Holly S.
I absolutely believe this helps my baby sleep better at night. I didn’t use one with our first and wish we would have.
Abby R.
It’s a functional sleep sack. I can’t say that it’s helped her sleep any better though.
Jennifer R.
My son has been using nested bean since 1 month, I find comfort in knowing I don’t have to put a blanket on him & worry about him being cold or him getting tangled in blanket while sleeping. Invest in your little ones! He also sleeps all night with it 10/10
Karynn M.
Very high quality and fits perfectly. This is our 5th bean and does not disappoint
Erica K.
Our little one did not sleep well at all. We were trying everything! Finally my MIL found this weighted sleep sack and it was a game changer! Once he was out of the swaddle we went with Nested Bean and won’t go back! So glad they have these up to 24 months. Wonderful product, high quality, would recommend for everyone!
Colleen M.
We were struggling to get my 1 year old to sleep past 4 am. I thought maybe he was getting cold and needed some cozy snuggles. These have been the perfect addition to our routine and sleep is going so well!
Avery K.
We love it! We went from sleeping 4 hours to sleeping 7-8 hours!
Brittany P.
Love our sleep sack and nested bean has the best customer service! We ordered the wrong size and they sent us the right one at no charge! So grateful for this to help our little one sleep so mommy & daddy can get some rest & function too :)
Traci H.
Love that it is lighter weight - perfect with a sleeper during winter months! Who does not love a good sleeping babe!
Puja P.
We've been a fan since we bought the 6-15 month sleep sack. Hopefully baby girl doesn't get too tall! The last one only worked til she hit 12 months and then she outgrew it. Very breathable and lightweight and she loves sleeping in it! Only reason for the 4 stars is how long I was able to use it for her.
Brinna C.
My baby has never slept better!! I’m much more at ease knowing my baby is comfortable and happy!
ash
great
Jannette C.
The nestedbean zen sack works wonders!! My baby boy is about to be 3 months next week and this is the first night he has slept over 9 hours Not to mention the sleep sack is super soft and just so cute!
Brenda F.
She sleeps all night.
It’s super easy to change her at night and keeps her warm!
Lauren R.
Love this product
Cameron H.
As soon as I put the Zen One on my 2 week old he instantly went to sleep. Instantly! It was amazing and he loves having his arms by his face, so the fact that he can have his arms out is a plus. I really think he likes the weighted part too, he loves being held. I will definitely be buying more!
Yvonne O.
Our baby loved her sleep sack . It gives her the freedom to move her arms and the comfort she is use to. We chose the winter style and love that it keeps her nice and warm .
Marianni L.
Love it! my 4 month old is going through sleep regression and this was a life saver. Mommy and daddy can now get some sleep and babe sleeps through the night !
Carla K.
Our little girl loves her zen sack! It is so soft and has a good bit of length so she can definitely grow into it. It has enough “weight” for her to have that feeling of our hands on her chest to settle her to sleep but light enough that she has no problem rolling from back to belly or vice versa. Biggest difference I’ve seen is during nap time, it used to be hard to get her to take naps in her crib but now settles pretty quickly. Highly recommend!
Amber W.
We transitioned from swaddle to nested bean at 2.5 months since our little lady likes to sleep on her side. They’re so soft and cozy. She’s been sleeping a full 8-10 hours at night now with her arms free!
Linda E.
First use was for a nap. She slept 2 1/2 hours! This was unusual for her! The night has not been as successful but we are hopeful.
Katie W.
Did not provide better sleep as advertised and shipping took longer than expected. When reaching out to customer service they were able to provide no additional support. For 10 days our tracking info never changed then one day the product randomly showed up after I had purchased something different. Very disappointed with the customer service support and shipping of the product.
Kasi B.
We absolutely love the nested bean for our 4 month old.
Autumn S.
We use it every night!
Elena M.
We love our gently weighted blanket!! Our baby loves it too. She seems to be sleeping much better than usual. We’re really happy
Tiffany S.
Absolutely love these sleep sacks.
Andrea G.
Didn’t really work for us. Very cute, well made and in theory is a wonderful idea. But my babe didn’t go for it. Tried it for a few days and nothing. Will maybe try again..
Natalie G.
My son wouldn’t sleep through the night and would wake up a bunch now he sleeps through the night and we’re finally getting some sleep too. He’s a tummy sleeper so with it being reversible it’s amazing
Gina P.
Love it
Sarah H.
This is great! Our baby loves it.
Jesse
This is the best sleeper I have tried yet! Just bought more!!
Kristin B.
I’ve always used sleep sacks for my son (swaddle sacks when he was a newborn) and I thought this would help him sleep better through his teething/9 month sleep regression but I haven’t really noticed much of a difference. The quality of the sleep sack is great. I love the material and how it’s designed. I just wish it helped my son sleep better.
Lukas H.
Can’t wait till our baby is older so we can use this product. Looks super soft and comfy. Love the color.
William M.
Excellent product!
Andrea C.
I have been using it on my 4-month-old and I have not seen any improvement on his sleep :( disappointed
Megan V.
Nestedbean is an AMAZING company. A pet ruined 3 of our zen sacks and they sent a free replacement. Customer service is top notch and the product actually works! Better sleep in 1-3 nights with both babies!
Thank you!
Courtney H.
Nested bean is my go-to baby shower gift because our boys LOVED them! We have great belly sleepers and the weight is perfect on their back!
Melissa D.
Absolutely love this sac. My little one definitely sleeps more comfortably. Will be buying a second one. Material is soft and holds up in wash. Two zippers for easy changing which is great! Great addition to our nightly and nap time routine.
Hilary K.
I love nested bean sleep sacks! They are nicely made, and keep my little guy cozy!

Fast shipping and great product
Danielle A.
The quality wasn't exactly what I expected, for $40, but it's fine. It didn't improve my baby's sleeping at all. Not too impressed, overall.
Michele H.
I really love these sleep sacks for my little one. She started in the Zen One Classic from about 2 mo to 6 mo, which completely changed her sleep within a few days. Then I purchased the Zen Sack. I really love how soft and cuddly feeling the front is and that it will last her until about 15 mo. It was an easy transition out of the swaddles sack and she can sleep on her stomach safely as well. She only had a minor disruption between sacks and is back to sleeping peacefully.
Gregory W.
It's a high quality product and I'm happy with the way it's made, how it feels, etc. My daughter sleeps in it every night but she's not necessarily sleeping through the night. I've given it about 2 weeks and very little difference in her sleep. It's all good. We tried another weighted sleep sack prior to this with no success so I wasn't expecting much. I wouldn't stop anyone from buying this. If it works for your child then that's awesome! And even if it doesn't work then it's still a high quality sleep sack for your child to sleep in.
Janet R.
Our 6 week old was struggling to stay asleep at night. I'm a huge fan of my weighted blanket so I wanted to give this a try for my girl. She has been sleeping 7 hours straight a night so far! She seems to love it!
olha k.
The best sleeping sack for us. Very good quality, soft cotton, nice color selection to choose from
Davida R.
My 4.5 month old son went from waking every 2-3 hours to sleeping 11 hours straight!
Kourtney S.
Had it for a couple weeks now and haven’t really noticed my daughter sleeping any better than before. I like that’s it’s a nice material and light but was hoping so see more of a difference.
Madison K.
It’s okay! I wouldn’t say that she slept better in 1-3 nights. She still doesn’t sleep through the night like all the other reviews state. She wakes up just as often to nurse back to sleep. I do think she wakes up in the middle of the night more peacefully and isn't immediately bursting into tears. I would buy another but I wouldn’t get your hopes up on the immediate change in sleep behavior!
Alexandria W.
We have used this sleep sack for about 6 months and love it! It's part of our bedtime routine and our daughter knows when we get it out that it's time for bed.
Amanda H.
Highly recommend these sleep sacs! We use them every nap and night for sleep and they keep our babe’s temperature correct through summer and so far through this winter. I’m only having this one babe, so I’ll be gifting these for eternity!
This seems like a crazy review, but for reals; these things are amazing!

We LOVE these sleep sacs! Seriously, they are amazing. I read recently that they can help with the routine of nap or bedtime and it totally works for our babe.

Best baby shower gifts ever. I buy one for everyone expecting
Tanna H.
She loves having her arms out so we struggled to find the right swaddle but once we tried nested bean she slept so well! 5-7 hours a night!

Nested Bean is one if the key ingredients to having a Great Little Sleeper! I’m a grandmother who wishes we’d had these 30 years ago. Great quality, pricing and sleep results - love this product!

This is our 2nd nested bean sack! We had struggled with getting our then 4 month old to sleep longer than 2 hours and moved to her room. The first night she slept 4 hours straight, not a peep, in her own room! The sleep sacks make such a difference in how much and the quality of sleep our little one gets. I recommend them to everyone!!

When he gets up for his midnight feeding it only takes a few mins to get him back asleep and he usually stays asleep. Only times he wakes up is when he wants his pacifier. But that’s rare now. This was a game changer for us!

Baby boy loves it and feels so comforted in this!

I can't tell if it's luck, but we got our sleep sack 2 days ago and my baby's sleep has substantially improved. Her naps are now over 1h long and she is able to resettle by herself in the meantime, which she wasn't doing before. I'm a fan! It's also super comfy and she seems to love being in it. I got the winter version and if things continue to be this amazing, I'll be purchasing the lighter versions for the spring/summer.

This worked really well for my little one. It did take about 2 days for her to get used to but by the third night she was sleeping better. Consistency is key and every night when I put her in her sack she knows it’s bedtime and looks forward to the snuggling into the sack.

We absolutely love our sleep sack! I wish we would have purchased one before now. Our baby girl was not sleeping past 40-45 minute mark for anything. Last night she slept from 930p-230a. Talk about refreshed! I woke up in a panic because she slept so good. Mama isn't use to that. We also appreciated the quality of the fabric, it is so soft.

Good

I have the regular sleep sack and the winter sleep sack and I had doubts but took a leak y of faith in desperation. These truly work! First night using them and my 3 month old slept 8 hours. 2-4 night he slept 8 hours, 5th night 6 hours and last night he slept 9 hours! I still can't beleive it. It's a miracle worker. He was sleeping 2 to 3 hours a night and I was losing my mind bc I work. This is a life saver. We are eternally grateful!

My daughter didn’t sleep for awhile at one time. She would sleep 5/10mins and back awake! At night time waking up in between her 2.5 hour sleep. When I started using the sack I was shocked how amazing it made a difference she now sleeps 3 hours before she wakes if I don’t put her in it at night she is constantly waking up! ❤️ Highly recommend!!!!!

I wasn’t sure if it worked because my daughter rolls around a lot in her sleep, switching to all kinds of positions, so I thought it would be uncomfortable and cumbersome, but when I switched back to her old zippered blanket, she wouldn’t let me put her in the crib for 2 nights in a row. To see if the nested bean really worked, or helped, I switched her back to it and she went back to sleeping in her crib! So it really does seem to work! Would be 5 stars if the shoulders and arm openings were a little bit bigger or softer/flexible. Otherwise seems like a great product and I’m pleased. Price point is also great. I love that you can wash and dry it normally! Most of her other bags are more expensive and require a lot of care.

My son sleeps so well in these sacks!

I bought this for my 5 month old granddaughter, and she loves it. The print is adorable and the weight is perfect for settling her to sleep. She tends to sleep warm, so the light weight fabric is perfect.
Megan R.
We live in Iowa and it is plenty warm for our sweet babe at night! We transitioned from a halo swaddle to the sleep sack and he sleeps great!
Jessica S.
Our son falls asleep easily, but usually wakes up every 3-4 hours during the night. The first night he wore the sleep sack he slept for 6 hours straight! Thought it was a fluke but tried it a different night and same outcome. It’s also made it easier to calm him into a nap during the day by mimicking the weighted egg with my hand on his chest. Will probably buy a second one!

Our 2 month old baby girl Wrennlee loves her new zen sack!!
Alejandra P.
Our little chunkster loveeesss her nested bean sack. This saved our sanity through the nights because the moment we put it on her she inmmediately falls asleep! It's like she knows it comforts her and it makes her feel cozy and safe. 10/10 get yourself a sack!!!! It's worth it!!
Courtney F.
Our tummy sleeper loves to wear hers backwards!
Jeana P.
The Zen Sack is ok. I wish to say it helped my baby sleep better but it didn’t do anything. Baby sleeps the same with or without the sack. Maybe it’s just him, always been anything but a good sleeper. However, the material is nice and it feels comfortable for him compare to other sleep sacks.
Kayla S.
Best cuddle

Bought it for my granddaughter and mom loves it!!!!
Jamie D.
My son’s favorite sleep sack.
Kendra R.
Perfect transition from a halo!
Courtney W.
The only mistake I made was not buying more than one! This momma is in love with this sleep sack! My daughter slept through the night for the first time in 6 months. And she still does almost a whole month later. It is washer and dryer friendly (trust! we've had plenty of accidents) I will be buying another soon! 10/10 recommend!
Rocio B.
My baby it’s kinda okay with it, she likes to move a lot so she wakes her self up haha
Karen S.
I purchased this for my grandson and it really seems to be working well
Tania R.
The sleep sack is okay. We have been using it in our transition to the crib but she still cries as she's a cuddler. The onesie is better but she is already outgrowing both.
Ann B.
My baby sleeps 5-6 hour stretches thanks to the nested bean sleep sack! Highly recommend for those sleep training their babies. Can’t wait to buy more!
Hanna C.
The Nested Bean sleep sack seems to help my baby soothe himself back to sleep when he rolls over in the middle of the night. We've bought the next size up because we liked his infant sleep sack so much!
Brooke S.
Love nested bean! We have used the newborn sacks and now this sleep sack! My baby wears it backwards because he is a stomach sleeper!
Brooke S.
My baby loves his sleep sack! He wears it backwards because he is a stomach sleeper! Only sleep sack we use!
Cory J.
I had high hopes for this sleep sack since my baby only sleep 2-3 hours at a time. I really haven’t noticed much a difference. I went without it for a few nights to see and I guess it helps her sleep a little better not much.
Lauren S.
Love this sleepsack. Light enough so it’s comfortable & not too hot for baby but cozy enough to soothe for bedtime.
Toni B.
This sleep sack is so nice and cozy!! It is made very high quality! I didn’t notice that the weighted chest made much difference with my baby but he is going through a sleep regression and maybe some other things right now as well. But again I love the quality and I know my baby is warm and cozy in a blanket that can’t hurt him ❤️ Thank you Nested Bean!
Sara S.
Absolutely love this sleep sack. The prints are gorgeous, great material and they wash well. We out ours on our girl backwards because she rolls to her tummy to sleep. We will be buying another couple for the next size up.
Sierra D.
My 6 week old was getting over the swaddle as he didn’t like being restrained! This makes him feel secure with having his hands out & we both like that
Diana S.
I was hoping that my 6 month old baby find real comfort and be able t sleep all night, however this was not the case. Although it didn’t work I am happy with my purchase, I Love how soft it is and easy to use during diaper changes ( night time .
Kim S.
Doesn’t help her sleep but love that it keeps her snug and warm!
Krystle G.
My daughter loves her sleep sacks! She started with the swaddle one then outgrew it so we switched to the swaddle and she gets excited every night when we put it on her because she knows it’s bedtime! Best sleep sack hands down!
Amber C.
My mother in law bought me a nested bean sleep sack from a garage sale. He was starting to get too big for his swaddle and I had already tried the “magic suit”. So I thought, “let’s try this tonight and see how he likes it.” He loved it! He’s grown out of the one that was given to me so I went ahead and bought 3 new ones that were bigger in size. Thank you so much Nested Bean for making a product that my baby loves and giving this momma some extra rest.
Cassandra P.
Doesn’t live up to the hype. My son doesn’t mind it, but it doesn’t make a difference in his sleeping at all.
Tobie B.
I never thought of using sleep sack because I always thought it won't work but I guess wrong. My baby can sleep longer than before. I can finally enjoy my sleep. I actually love it
Frequently asked questions
-
How much weight is in the Zen Sack® Classic sleep sack?
All Zen Sack 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 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.
-
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.
