For some reason I thought this one was black and it is more blue for sure. Also after washing it once this color collects a lot of lint and makes it look worn out. Kind of bummed about that but my daughter does love these sleep sacs
Stephanie S.
Such a soft but warm material for my baby. She sleeps so cozy and comfortable in the Nested Bean sleep sack!
Mackenzie H.
Love our Nested Bean sleep sacks! Helps my daughter sleep through the night and is soft, comfortable. It shipped super fast, too!
Karly M.
YES! So good
Laila A.
A fantastic sleep sack. My LO sleeps soundly. I almost wish they had adult sized ones haha.
Kayli M.
Our boy LOVES his nested bean sleep sack! He used to LOVE being swaddled but then decided that he still loved it but without his arms being swaddled but I wanted to just give this sleep sack a try & it was an instant hit. Definitely wish I would've bought 2 though so I always had one ready if the other got spit on or something! Will be purchasing another asap!
KYLIE K.
My baby lives this thing! Easy transition for her
Lindsay G.
Our baby outgrew the swaddle but is very active. We bought this in hopes it would help her sleep swaddle free. 3 days in and she slept through the night. Highly recommend.
Lindsay
I ordered my first sleep sack for my daughter when she was a newborn and it did fit nicely. I decided to order another one now that she is 9 months. I got the 0.5 in her age bracket, since summer is approaching and it does get quite warm where I live. My daughter is quite long, in the 95th percentile for height and weight. I feel that the sleep sack is a bit small for her. It does fit her currently, but I feel like she will outgrow it by next month.
Kayla H.
Better sleep was on the way! We love this sleep sac. We have tried so many but now that he is starting to roll he doesn't care much for them. This one keeps him warm when the AC is on but cool enough to sleep well. We love that we can flip it around to provide comfort in different ways.
Jessica F.
Hasn’t helped my baby with sleeping, but keeps him warm.
Johanna L.
Great material, and looks great, but did nothing for sleep. It’s hopeless!
Jennifer F.
Love the pattern!
Jennifer F.
These sleep sacks are the best!
Kate R.
my little one loves her zen sack!
Colleen F.
We have a Zen Sack Classic and a Zen Sack Quilted and despite being the same size they are significantly different. The Zen Sack Classic is 3 inches shorter than the same size of the Zen Sack Quilted. We love the product just wish there was some consistency in the sizing. The classic was a waste of money for us since our son never fit in it despite still fitting comfortably in the quilted version.
Celia S.
My 16 month old had a sleep regression. I ordered baby melatonin and this sleep sack. Both helped. I tossed all the other sleep sacks and only use this one. My daughter sleeps on her tummy so I put the weighted part on her back.
Karen B.
Love this product. Our son is a great sleeper but he was starting to roll over in the Magic Merlin suit. We switched to the Nested Bean after a friend recommended it. Took one night for him to get the hang of it. The suit is so cute, the fabric soft.
My only question is - if he rolls on to his stomach, will the weighted bean that’s sewn into the chest area be uncomfortable, preventing him from sleeping in that position?
Hannah S.
This is our third nested bean sleep sack! We really like them, but we’ve never tried anything else so I can’t compare it to anything else.
Lisa R.
Bought as a gift
Vanessa D.
Our newborn hates to be restricted and loves having her hands and arms free as she sleeps now 7+ hours through the night!
Kaitlin D.
Love the material this is made of! I have a super hot natured baby and this is perfect for him.
Courtney W.
Super soft & my daughter is sleeping through the night!
Jasmine N.
It’s okay, I got it when my son was 6 months and he did struggle at first to sleep in swaddled and not sure if the weighted area helped much, but he is sleeping better through the day and night, not fully sleeping through the night still. Not sure if the sack is helping in any way but definitely was worth a try.
Melissa W.
My tiny human falls asleep in less than 10 minutes with the Nested Bean Zen Sack! He sleeps longer stretches and is knocking that 4 month sleep regression out of the park!
Katie K.
We liked this sack for our daughter who is 2 and a half months now. She never really liked swaddles, and this would keep her legs covered without constricting her. My only criticism is that I feel like the shoulder straps are too snug on her. Especially for a 0-6 month fit. Had I known this, I probably would have gotten a size up. So now we only use it occasionally.
Melissa W.
I’ve bought a lot of sleep sacks between 2 babies and this one is fine. I’m not a big fan of the shoulder snaps as they allow for minimal adjustment but otherwise are hard to mess with at night (if you want to fully remove it for a feeding) and they add some bulk.
Adele C.
I absolutely love this zen sack! My daughter has slept through the night since using this when she was around 4 months old. I would highly recommend giving it a shot. I know that every baby is different, but this may be the missing piece for you to get your baby to sleep through the night like it was for me!
Paola H.
It really works!! My baby boy is about to be 4 months next week and he has been slepping 6 / 7 hours at night I got a size 6-15 months and I am glad I did (he is a tall baby)
The sleep sack is super soft and cute!
olivia s.
I can’t say that it’s made a difference in his sleep. Will keep trying
Mary T.
Exactly what I wanted! We have used the nested bean sleep sacks for a while and love them! Just needed a new one for my new little guy.
Amber D.
The material of this sleep sack is so smooth. It doesn’t get too hot for my baby and keeps him comfy all night!! Will definitely be buying this as gifts and in bigger sizes!
Philip M.
Our little guy has used one of these essentially since birth. He grew out of the old one and seems to be liking this bigger size so far. Would recommend.
Rebecca S.
Love it! My son is a back sleeper and this is perfect for him
Kaci P.
We LOVE Nested Bean♥️
Now that babygirl is rolling over in her sleep & sleeping on her stomach we are going to switch the weighted side to her back to help her stay asleep!
We have a total of 6 sleep sacks now & I can’t recommend enough!!
Brooke W.
This sleep sack is super cute and convenient with the zipper and snap straps! I was keen to try it based on reviews by others it has worked for. I’ve had this for a couple weeks and it didn’t magically help keep baby asleep through the night. Babies are not one size fit all. This product hasn’t helped significantly in any way but the way this product is designed is genius.
Mariah W.
My son is a year old and has never slept more than 7 hours straight at night. We’ve tried everything and finally bought this sleep sack. I’m just 3 nights, he went from waking up every 3 hours to sleeping 9 hours straight! I’m sure with this sleep sack and little bit of prayer, your baby will be sleeping much better, too!!
Martha E.
I'm not sure what kind of magic is in this sleep sack but it's amazing! My son immediately calms down and falls right asleep every time he is put in it. I recommend these to all of my friends with babies now!
Laura S.
We love nested bean sleep sacks. Baby number two has decided he will not sleep through the night without being in his sack.
Tina P.
This was for my niece’s baby. Not yet born. But she really liked it. I’m sure baby will too. In may.
Rebecca L.
I love the way the material feels; soft, light, and breathable for my baby. She enjoys wearing her sack and keeps her warm at night. Thank you!

Briana D.
My 3 month old daughter sleeps well, but sometimes wakes when I lay her down. Last night she didn’t wake up at all and slept great all night! So far we are a fan.
Ivey
Baby girl is loving it. Finally getting more than 3 hour stretches of sleep! 6 hours last night
Savanna T.
Game changer! We started implementing this in our nightly routine. Within 2 nights he was sleeping for 5-7 hours stretches at night.
Grace M.
We had such a hard time switching from wrapped swaddle to unwrapped until we found Nested Bean! She doesn’t sleep without it. And it has been a life saver!
Laura B.
My 4 month old has been using the nested bean sleep sacs for 3 months now. My aunt bought us our first ones. Now we use them everyday. The baby goes to sleep so much better and faster with the nested bean sleep sac on. We also put it on for naps. They are so amazing!!! So glad that when baby starts rolling over all we have to do is put the sleep sac on so the weights pouch is on the back.
Rebecca
My son is a stage 5 clinger and he slept for the longest stretch by himself ever on night one wearing this sack. I am so hopeful this trend will continue!
LILIANA I.
Started using the classic sack around 3 mo’s. At first I didn’t really see a difference. I did see a difference after constant use naps and bedtime maybe 9 months old. Our baby giggled when would see it, happy to go sleep. It saved our sanity during a 5.5 hr flight when 1.5 yrs old. Nothing worked, cried 1.5 hrs nonstop, no one rested around us. Felt terrible! Had the sack in the bag, decided to put on. Saved us!!! On way back, sack on as soon as got on the plane, way different, it calmed the baby entire flight. Baby is 2 now, he asks for it for his naps, bedtime. Loves those beans. Literally holds them while sleeping. The thicker sack was a no go for us. Totally refused it. Overall we’re so pleased with the sack!!!
Elisha D.
Our little love insist on being held while sleeping. The nested bean has made it possible for her to sleep on her own!!
Eliza B.
The Nested Bean sleep sack is made of high quality material and is super cute!! Love all the colors and fun patterns! Did not help my daughter with her sleep at all but I love the quality of the sleep sack.
zara f.
Mommy’s best friend !
Brittany C.
Our daughter HATED to be swaddled but her startle reflexes would wake her up when being moved from our arms to the crib or bassinet. The Zen Sack gave her that comfort of being wrapped up without being restricted. She now has longer naps and sleeps very well at night.
Shalaka S.
We like the sleep sack but the packaging is terrible. It made a total mess all over the place and the sack.
Stevie E.
My 4mth old sleeps pretty decently and a little longer while using the sack! He is teething right now so he doesn't sleep for too long, but we are liking the sack!
Tony P.
This product is Great! MIHIR
Angela W.
Granddaughter loves it!!!
Lauren G.
Definitely helps gets my baby to sleep after a night feeding. It has made resting easier.
Vanessa C.
Has made transition to the crib a breeze. I bought 2 more. Like the quilted version, seems warm but not too hot. I don’t worry about her being chilly.
Grace M.
We don’t sleep without it!
Alysha T.
My daughter is 7weeks old and hates to be swaddled. Especially with her arms in. So I figured I’d give this a try. She sleeps so good at night! Would recommend to anyone!
Preslee H.
Love our nested bean sleep sack!
Samantha F.
Do not regretting buying!!! If you’re reading the reviews debating on purchasing go ahead and do it.
Jennifer S.
We use it every night! We don’t go to bed without our nested bean!
Melissa R.
Well the fabric it’s good but honestly it didn’t do anything different to my baby sleep.
Angela G.
I’ve Been using our sleep sack for over a week and haven’t noticed much of a difference, except my 6 month old son falls asleep faster, but is still waking up every 2-3 hours.
Kelly B.
We don’t go to sleep without our nested bean on :) game changing!
Tara S.
All of my children did and currently love sleeping in the nested bean.
Celestine N.
I do like the sleep sacs, I’m not sure if they help my child sleep as she was starting to sleep through the night when I bought them. They are long on the bottom which is what I was looking for. I was however disappointed in the difference in quality in the 2 sleep sacs I ordered. They had many small differences but the biggest I noticed was the weighted part in one was filled more than the other. They did send me a new one but it was the same as the other I had so maybe the one was just overfilled instead of the other being under filled? I was happy with the customer service but I feel like for the price point they should have more consistency.
Olivia E.
Love nested bean! Has help with our sons sleeping
Dawn C.
My granddaughter can't sleep without it! Amazing
Katie C.
I love this item!! Just very expensive.
Pandhita P.
It didn’t really work for our baby. His sleeping pattern or duration didn’t change at all since we started using this product. It’s almost two weeks since we started using it…. So I don’t know if this product will ever work for us :(
Sarah F.
We notice an immediate improvement in their sleep patterns when they wear their Zen Sacks!
julia h.
this sleep sack is very soft and cute! however, i’d recommend sizing up if you have a higher percentile baby. I got the medium (6-15mo) for my 10 month old and I know she’ll be too long for it way before 15 months.
Marketa R.
My little one loves Nested Bean sleep sack. We are using it since she was 6 months old and it has improved her sleep quality so much!
Richie K.
We love the zen classic sleep sack! It’s the perfect thickness (not too thick, not too thin) for the weather we have and our temperature controlled home. The weighted part on the chest is perfect as well. Just enough to make her feel like she is still being touched.
Katie E.
We transitioned from full swaddle to the sleep sack and it was so smooth! Our 6 month old LOVES the sleep sack and sleeps great in it.
Val C.
I am so glad I tried the Nested Bean weighted sleep sack. My baby boy was a non-sleeper. He'd get up all night, and this went on for his whole first year. I tried everything, including upgrading to a Newton breathable crib mattress when he was ~6 months old (which I also love) so he could sleep on his tummy (his preferred method), but that alone did not fix the problem. I decided to purchase the Nested Bean because it is reversable, meaning I could put the weighted side on his back. I've tried other weighted sleep sacks, but they were too heavy to put on "backwards", and so heavy in fact, he had trouble standing up in his crib wearing them which was concerning. Nested Bean did the trick! And they're the perfect weight. We saw an improvement once we tried the 6-15 months size, where the little bean sack is a small oval on his back/chest. When we upgraded to the 15-24 months size, where the beans go across his entire back, he sleeps 11+ hours without waking AND I can put him down before he's asleep and he'll calmly fall asleep on his own. We have a summer sack, a classic sack, and a quilted winter sack and we love them all. Great company, and high-quality, thoughtful products. Highly recommend!!! My only regret is not discovering the brand when he was an infant, so I could start swaddling him immediately :)
Natalie P.
This is our third size of the weighted sleep sack. My daughter loves it and we have continued to by her bigger sizes as she grows.
Sharon G.
Well made. Very soft! For my wonderful grandchild, E B R. Thanks for a great product!
Elisa R.
I bought this at a desperate moment around 3:30 in the morning when our six month old wasn’t sleeping well. The reviews are spot on. As soon as this bad boy arrived, we wrapped our little one up and we’ve been on consistent sleep since then! The weight is just right and she loves the freedom of the space. I now need to buy another one for back up.
Gabriella P.
My newborn lasted very few in swaddles, plus she is trying to turn since month one. Ever since we changed to the Nested Bean Sleep Sack she sleeps more comfortable and we fill relieved that she can also move freely.
Cam
My baby was having a hard time transitioning out of the swaddle. I put him in this sleep sack and he slept great all night with his arms free!
Elizabeth R. T.
My son is 12 weeks old and has alot of gas. This did not do the miracle that it has done for alot of others. I have put it on him ever since we got it. It is going to be about 2 weeks now. I can say that he does let me put him down without fussing but he doesn’t sleep for more than maybe 4 hours in it. This is why I gave it an it’s okay because I don’t think it’s horrible, but it hasn’t been the greatest thing ever like most people are commenting here.
Danielle W.
Absolutely love!!!
Brenda P.
We received one of these as a gift when my twins were 5 months old. They've slept with one ever since, they sleep so much better it on! The few times we've forgotten to put it on they seem to toss and turn most of the night. We love ours!
Paige B.
This sleep sack works really well for us. The quality and weight feel really good. The shoulder snaps are a nice addition to the side zip, giving us an extra way to pull him out of it in the morning. I also like that it's reversible for our tummy sleeper. Nothing but good things to say!
jessica b.
It is made well and cute but can't say I see any difference at all in sleep pattern unfortunately
Jacqueline K.
Our daycare had one of these, that he was sleeping all the time, since they can’t swaddle him there. We took it home one weekend, and just knew we had to have one for our home.
Nichole M.
Both my boys started sleeping through the night after we purchased Nested Beans. The older son preferred the footsie pajamas while his little brother preferred the Zen and Classic Sack. I recommend these to all our friends! The weight is just comforting enough to put themselves to sleep and they love lounging in them right before bed. Very soothing and soft fabric.
Natalie L.
I’m not seeing a difference in my sons sleep. We’ve been using for over a week and he’s still sleeping his usual schedule (waking every 3-4 hours). Not sure if it’s just his age (14 weeks). I also find the zipper a little bulky.
Jenieca I.
Love nested bean sleep sacks!! I bought one for my daughter (FTM) when she was around 4-5 months. I swear she slept through the whole night till 7am when I started using it. She's a pretty tall/long girl so she grew out of her original one after a few months and I noticed along with sleep regression she started waking up again at night at least 1-2 times. So I just purchased the 15-24 month sleep sack after her first birthday and she's back to sleeping so well at night! I use it at nap time too and she actually gets some pretty good sleep in during the day now too. Highly recommend
Arunee A.
My son is almost 6 month old and I looking swaddle transition for him and decided to try Nested Bean but it doesn't work for him, he is still wake up 2 time at night:(
Audrey H.
My daughter made the transition from the Merlin Sleep Suit to the Nested Bean Sleep Sacks. She is now almost 6 months old, and is a full on stomach sleeper. There is no stopping her! So the little weighted bean for her back seems to soothe her nicely during naps and overnight. They are comfy, a good price, easily washable, and she will use them for a long time!
Morgan K.
Around 3 months our baby started sleeping through the night on his own. But month 4 when he started teething, his night sleep became all over the place. We also noticed that when we put him down in his crib he would jerk himself awake. The zen sack coupled with making sure he gets a good nursing session in right before bedtime has helped him sleep through the night. And he doesn’t jerk himself awake when we put him down anymore because of that extra weight/comfort from the zen sack. Def recommend!
Brittany R.
I love those sleep sacks! Hands down the best I have ever used with both of my kids. I was having issues with my son sleep at night and after 2 nights with the sleep sack, he slept 6 hours without waking up! I highly recommend this Product.

Baby girl is loving it. Finally getting more than 3 hour stretches of sleep! 6 hours last night

Game changer! We started implementing this in our nightly routine. Within 2 nights he was sleeping for 5-7 hours stretches at night.

We had such a hard time switching from wrapped swaddle to unwrapped until we found Nested Bean! She doesn’t sleep without it. And it has been a life saver!

My 4 month old has been using the nested bean sleep sacs for 3 months now. My aunt bought us our first ones. Now we use them everyday. The baby goes to sleep so much better and faster with the nested bean sleep sac on. We also put it on for naps. They are so amazing!!! So glad that when baby starts rolling over all we have to do is put the sleep sac on so the weights pouch is on the back.

My son is a stage 5 clinger and he slept for the longest stretch by himself ever on night one wearing this sack. I am so hopeful this trend will continue!

Started using the classic sack around 3 mo’s. At first I didn’t really see a difference. I did see a difference after constant use naps and bedtime maybe 9 months old. Our baby giggled when would see it, happy to go sleep. It saved our sanity during a 5.5 hr flight when 1.5 yrs old. Nothing worked, cried 1.5 hrs nonstop, no one rested around us. Felt terrible! Had the sack in the bag, decided to put on. Saved us!!! On way back, sack on as soon as got on the plane, way different, it calmed the baby entire flight. Baby is 2 now, he asks for it for his naps, bedtime. Loves those beans. Literally holds them while sleeping. The thicker sack was a no go for us. Totally refused it. Overall we’re so pleased with the sack!!!

Our little love insist on being held while sleeping. The nested bean has made it possible for her to sleep on her own!!
Eliza B.
The Nested Bean sleep sack is made of high quality material and is super cute!! Love all the colors and fun patterns! Did not help my daughter with her sleep at all but I love the quality of the sleep sack.

Our daughter HATED to be swaddled but her startle reflexes would wake her up when being moved from our arms to the crib or bassinet. The Zen Sack gave her that comfort of being wrapped up without being restricted. She now has longer naps and sleeps very well at night.
Shalaka S.
We like the sleep sack but the packaging is terrible. It made a total mess all over the place and the sack.
Stevie E.
My 4mth old sleeps pretty decently and a little longer while using the sack! He is teething right now so he doesn't sleep for too long, but we are liking the sack!
Tony P.
This product is Great! MIHIR
Angela W.
Granddaughter loves it!!!
Lauren G.
Definitely helps gets my baby to sleep after a night feeding. It has made resting easier.
Vanessa C.
Has made transition to the crib a breeze. I bought 2 more. Like the quilted version, seems warm but not too hot. I don’t worry about her being chilly.
Grace M.
We don’t sleep without it!
Alysha T.
My daughter is 7weeks old and hates to be swaddled. Especially with her arms in. So I figured I’d give this a try. She sleeps so good at night! Would recommend to anyone!
Preslee H.
Love our nested bean sleep sack!
Samantha F.
Do not regretting buying!!! If you’re reading the reviews debating on purchasing go ahead and do it.
Jennifer S.
We use it every night! We don’t go to bed without our nested bean!
Melissa R.
Well the fabric it’s good but honestly it didn’t do anything different to my baby sleep.
Angela G.
I’ve Been using our sleep sack for over a week and haven’t noticed much of a difference, except my 6 month old son falls asleep faster, but is still waking up every 2-3 hours.
Kelly B.
We don’t go to sleep without our nested bean on :) game changing!
Tara S.
All of my children did and currently love sleeping in the nested bean.
Celestine N.
I do like the sleep sacs, I’m not sure if they help my child sleep as she was starting to sleep through the night when I bought them. They are long on the bottom which is what I was looking for. I was however disappointed in the difference in quality in the 2 sleep sacs I ordered. They had many small differences but the biggest I noticed was the weighted part in one was filled more than the other. They did send me a new one but it was the same as the other I had so maybe the one was just overfilled instead of the other being under filled? I was happy with the customer service but I feel like for the price point they should have more consistency.
Olivia E.
Love nested bean! Has help with our sons sleeping
Dawn C.
My granddaughter can't sleep without it! Amazing
Katie C.
I love this item!! Just very expensive.
Pandhita P.
It didn’t really work for our baby. His sleeping pattern or duration didn’t change at all since we started using this product. It’s almost two weeks since we started using it…. So I don’t know if this product will ever work for us :(
Sarah F.
We notice an immediate improvement in their sleep patterns when they wear their Zen Sacks!
julia h.
this sleep sack is very soft and cute! however, i’d recommend sizing up if you have a higher percentile baby. I got the medium (6-15mo) for my 10 month old and I know she’ll be too long for it way before 15 months.
Marketa R.
My little one loves Nested Bean sleep sack. We are using it since she was 6 months old and it has improved her sleep quality so much!
Richie K.
We love the zen classic sleep sack! It’s the perfect thickness (not too thick, not too thin) for the weather we have and our temperature controlled home. The weighted part on the chest is perfect as well. Just enough to make her feel like she is still being touched.
Katie E.
We transitioned from full swaddle to the sleep sack and it was so smooth! Our 6 month old LOVES the sleep sack and sleeps great in it.
Val C.
I am so glad I tried the Nested Bean weighted sleep sack. My baby boy was a non-sleeper. He'd get up all night, and this went on for his whole first year. I tried everything, including upgrading to a Newton breathable crib mattress when he was ~6 months old (which I also love) so he could sleep on his tummy (his preferred method), but that alone did not fix the problem. I decided to purchase the Nested Bean because it is reversable, meaning I could put the weighted side on his back. I've tried other weighted sleep sacks, but they were too heavy to put on "backwards", and so heavy in fact, he had trouble standing up in his crib wearing them which was concerning. Nested Bean did the trick! And they're the perfect weight. We saw an improvement once we tried the 6-15 months size, where the little bean sack is a small oval on his back/chest. When we upgraded to the 15-24 months size, where the beans go across his entire back, he sleeps 11+ hours without waking AND I can put him down before he's asleep and he'll calmly fall asleep on his own. We have a summer sack, a classic sack, and a quilted winter sack and we love them all. Great company, and high-quality, thoughtful products. Highly recommend!!! My only regret is not discovering the brand when he was an infant, so I could start swaddling him immediately :)
Natalie P.
This is our third size of the weighted sleep sack. My daughter loves it and we have continued to by her bigger sizes as she grows.
Sharon G.
Well made. Very soft! For my wonderful grandchild, E B R. Thanks for a great product!
Elisa R.
I bought this at a desperate moment around 3:30 in the morning when our six month old wasn’t sleeping well. The reviews are spot on. As soon as this bad boy arrived, we wrapped our little one up and we’ve been on consistent sleep since then! The weight is just right and she loves the freedom of the space. I now need to buy another one for back up.
Gabriella P.
My newborn lasted very few in swaddles, plus she is trying to turn since month one. Ever since we changed to the Nested Bean Sleep Sack she sleeps more comfortable and we fill relieved that she can also move freely.
Cam
My baby was having a hard time transitioning out of the swaddle. I put him in this sleep sack and he slept great all night with his arms free!
Elizabeth R. T.
My son is 12 weeks old and has alot of gas. This did not do the miracle that it has done for alot of others. I have put it on him ever since we got it. It is going to be about 2 weeks now. I can say that he does let me put him down without fussing but he doesn’t sleep for more than maybe 4 hours in it. This is why I gave it an it’s okay because I don’t think it’s horrible, but it hasn’t been the greatest thing ever like most people are commenting here.
Danielle W.
Absolutely love!!!
Brenda P.
We received one of these as a gift when my twins were 5 months old. They've slept with one ever since, they sleep so much better it on! The few times we've forgotten to put it on they seem to toss and turn most of the night. We love ours!
Paige B.
This sleep sack works really well for us. The quality and weight feel really good. The shoulder snaps are a nice addition to the side zip, giving us an extra way to pull him out of it in the morning. I also like that it's reversible for our tummy sleeper. Nothing but good things to say!
jessica b.
It is made well and cute but can't say I see any difference at all in sleep pattern unfortunately
Jacqueline K.
Our daycare had one of these, that he was sleeping all the time, since they can’t swaddle him there. We took it home one weekend, and just knew we had to have one for our home.
Nichole M.
Both my boys started sleeping through the night after we purchased Nested Beans. The older son preferred the footsie pajamas while his little brother preferred the Zen and Classic Sack. I recommend these to all our friends! The weight is just comforting enough to put themselves to sleep and they love lounging in them right before bed. Very soothing and soft fabric.
Natalie L.
I’m not seeing a difference in my sons sleep. We’ve been using for over a week and he’s still sleeping his usual schedule (waking every 3-4 hours). Not sure if it’s just his age (14 weeks). I also find the zipper a little bulky.
Jenieca I.
Love nested bean sleep sacks!! I bought one for my daughter (FTM) when she was around 4-5 months. I swear she slept through the whole night till 7am when I started using it. She's a pretty tall/long girl so she grew out of her original one after a few months and I noticed along with sleep regression she started waking up again at night at least 1-2 times. So I just purchased the 15-24 month sleep sack after her first birthday and she's back to sleeping so well at night! I use it at nap time too and she actually gets some pretty good sleep in during the day now too. Highly recommend
Arunee A.
My son is almost 6 month old and I looking swaddle transition for him and decided to try Nested Bean but it doesn't work for him, he is still wake up 2 time at night:(
Audrey H.
My daughter made the transition from the Merlin Sleep Suit to the Nested Bean Sleep Sacks. She is now almost 6 months old, and is a full on stomach sleeper. There is no stopping her! So the little weighted bean for her back seems to soothe her nicely during naps and overnight. They are comfy, a good price, easily washable, and she will use them for a long time!
Morgan K.
Around 3 months our baby started sleeping through the night on his own. But month 4 when he started teething, his night sleep became all over the place. We also noticed that when we put him down in his crib he would jerk himself awake. The zen sack coupled with making sure he gets a good nursing session in right before bedtime has helped him sleep through the night. And he doesn’t jerk himself awake when we put him down anymore because of that extra weight/comfort from the zen sack. Def recommend!
Brittany R.
I love those sleep sacks! Hands down the best I have ever used with both of my kids. I was having issues with my son sleep at night and after 2 nights with the sleep sack, he slept 6 hours without waking up! I highly recommend this Product.
Aspen S.
Great quality!
Sheri C.
This is a gift for a friend who has yet to have her son but my grandson has a few and they are great.
Frequently asked questions

How much weight is in the Zen Sack® Classic sleep sack?
All Zen sleep sacks feature a built-in Cuddle Pad™, which weighs just 30 grams (Small size) 60 grams (Medium size) and 90 grams (Large size and distributed across the chest). Our baby sleep sacks are safely weighted in key areas as opposed to all-weighted sleep sacks or weighted blankets, which the AAP has deemed unsafe for infants.
-
What’s the difference between Nested Bean weighted baby sleep sacks products?
Nested Bean offers a variety of sleep sacks, all of which are designed to calm like your embrace: Zen Sack® Classic, Zen Sack® Premier, Zen Sack® Winter and Zen Sack® Quilted. The difference between our weighted sleep sacks is the fabric used for construction. Zen Sack® Classic is made from 100% breathable cotton, and is perfect for year-round use. Zen Sack® Premier ,made from 70% rayon from bamboo for luxurious softness and 30% cotton for strength, is lightweight for warmer temps. Zen Sack® Winter is made from 100% cotton, with a 2.5 TOG and heavy poly-fiber filling for colder weather. And Zen Sack® Quilted is a cozy transitional sleep sack, for when temps start to drop.
-
Are Nested Bean weighted baby sleep sacks safe for babies who roll over?
All Zen Sack® sleep sacks were designed for rollers and tummy sleepers; they help babies get longer, more peaceful sleep through all growth stages. The Small and Medium size sleep sacks have a gently weighted Cuddle Pad™ on the front that is so light and flexible, it nearly flattens when baby rolls to their tummy. The sleep sack can also be reversed and worn backwards for tummy sleepers who roll independently, placing the weighted center on baby's back for uninterrupted comfort all night.
-
What is the Cuddle Effect™—and how do Nested Bean sleep sacks trigger it?
The Cuddle Effect is a proven metabolic response that babies experience when they are held, that triggers relaxation and well-being, improves sleep and promotes healthy development. Research on Deep Touch Pressure (DTP) shows that babies experience the Cuddle Effect when they feel gentle pressure in the places you naturally hold them. Nested Bean sleep sacks are designed with gently weighted Cuddle Pads™ that calm like your embrace and trigger the Cuddle Effect for longer sleep.
-
Do Nested Bean weighted sleep sacks meet industry safety standards?
Nested Bean baby sleep sacks adhere to all Consumer Product Safety Commission guidelines around product construction, flammability and more. The Cuddle Pad™ in our sleep sacks is self-contained and cannot cause overheating, and the gentle weight does not restrict movement: For example, the Zen Sack™ sleep sack is safe for tummy sleepers, rollers and side sleepers.
-
When should you start using a Nested Bean sleep sack?
Once babies start rolling, swaddling stops—and it’s time to transition to a baby sleep sack. Only Nested Bean sleep sacks contain Cuddle Pads™ that are gently weighted to ease the transition from swaddle to sleep sack, so babies experience uninterrupted comfort and longer sleep.
-
How long does it take Nested Bean sleep sacks to work?
As with all our gently weighted Zen Sleepwear™, most parents report that our baby sleep sacks improve their baby’s sleep in 1 to 3 nights.
-
What is TOG—and how does it differ between Nested Bean sleep sacks?
TOG is a measure of thermal insulation. It is a commonly used term the textile industry to indicate how warm clothing is. The higher the TOG in baby sleep sacks, the better thermal insulation it provides and the warmer it is. For example, the Zen Sack® Classic sleep sack has a TOG of 0.5, perfect for year-round use. The bamboo Zen Sack® Premier sleep sack has a TOG of 0.3, for warmer weather. The Zen Sack® Quilted sleep sack has a TOG of 1.0, great as temps begin to fall. And the Zen Sack® Winter sleep sack has a cozy TOG of 2.5, just right for chilly nights.
-
What is the Grow-with-Me feature of Nested Ben sleep sacks?
Nested Bean sleep sacks contain 2 sets of snaps on the shoulders. The bottom snap offers a snug fit, while the top snap offers more room as your baby grows.
-
How do Nested Bean sleep sacks hold up in the washing machine?
All Nested Bean weighted baby sleep sacks are made of the highest-grade fabrics, and are designed to be super durable and withstand multiple washings. To protect the fabric quality, we recommend washing our baby sleep sacks in cold water, on a gentle cycle and tumble dry on low heat.
