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
Sharon G.
I bought it for my grandson who was having a difficult time transitoning to the crib. He went quickly to sleep and we discovered he is a stomach sleeper! Thank you very much!!
Danielle P.
I've used the zen sack for my two girls ! My 3 year old sleeps through the night now because we used the zen sack and sleep trained her to fall asleep on her own since she was a newborn we did this exact thing with my now 5 month old who is colic and she sleeps amazingly as well (she still wakes up but without the sack its every 3 hours with the zen sack its every 5 hours ) I can't express how much this sleep sack has helped me get a better night sleep with my babies i really wish I knew about this when I had my son 6 years ago cuz it is a big game changer ! I've even purchased the sleep sack for every single baby shower we have went to in the past 3 years and every person I've got it for has thanked me so much for it because how big of a difference it made to their babies sleep !!!!.......DO IT !!! GET IT !!! ITS NOT A SCAM IM A MOM OF 3 WHO USED IT WITH 2 OF MY 3 AND IT CHANGED MY LIFE !! I WAS A ZOMBIE WITH MY FIRST CHILD CUZ HE N3VER COULD SLEEP UNLESS HE WAS HELP THIS CHANGEDDDDDD IT ALLLLL !!!! SPEND THE MONEY !
Hillarie D.
Love the sleep sack! Super fast shipping!
Lily P.
My daughter has been wearing the classic Zen sack since she was 3 months old! She is now 1. I absolutely love it , and apparently so does she. We only use it at night, and it helps her sleep the whole night through. Happy costumer here!
Marisa W.
We love the nested bean sleep sacks! We used them with my first daughter and now with my second daughter and they are a lifesaver for us. The one thing that was odd about the pink one compared to all the other ones we have purchased was, there was a huge tag on the outside of the sleep sack that I would’ve expected to be on the inside of the sleep sack instead. I just cut them off but seemed weird none of our other ones were like that.
PAULA C.
I love the nest! Baby takes longer naps
Kaitlynn a.
My two month old has been sleeping 8 hour stretches since the first week we started wearing the zen sack. I am a true believer! My sister in law suggested buying this sack after her baby started sleeping through the night in his zen sack and I couldn’t be happier that we both are having such great success.
Isabelle G.
My baby usually twitches a LOT, which keeps her from getting a full night’s sleep, but with the weight on her chest, she gets startled less and sleeps in more; able to get full 6-8 hours of sleep!
kalynn
We absolutely love Nested Bean! Our baby has been sleeping in one since the day we brought her home and I think it plays a huge role in why she sleeps so well. She has been a great sleeper from day 1 and was sleeping through the night by 6 weeks old (probably would have sooner, but I was still waking her up for feeds). We have two of their sacks that we switch back and forth between, but she loves both. Great investment for your little one!
Emily P.
I love the quality of the sleep sack and how the buttons are on the shoulders and have the zip around the legs too! I feel like my baby didn’t notice a helpful difference with it being weighted though.
Hannah F.
This has been great so far! Baby Live sleeping on his stomach in this. He continues to sleep soundly. See less transition :)
Tobie B.
I can finally now have my sleep. With this sleep sack, my baby can enjoy having a long hour sleep. I like how the material is soft and it doesnt make my baby sweat at night. I also like how it's a easy change diaper
Tiffany N.
Truly believe the weighted bean has helped our little guy enjoy sleeping on his tummy. He would always roll over and scream. No more holding a hand on him until he falls asleep!
Holly P.
Work great
Jessica G.
My baby loves her sleep sack! She sleeps 5 hour intervals in it!!
Melissa W.
I absolutely love the quality of my sleep sack:) it’s super soft and the weight seems to be just perfect. I can’t wait to purchase the next size up once my little one grows out of the 0-6months:)!!
Madison R.
My LO loves this sleep sack! He takes longer naps and doesn’t toss and turn during his sleep anymore!
Tess
My friend gave me one of the sleep sacks to try before I purchased one as our 2 month old just hit 8lbs. She is such an active sleeper to the point where she was constantly waking herself up. I didn’t think it would make much of a difference in her sleep but man I was wrong! The weighted egg is just the right amount and keeps her settled. This is our 3rd night and it’s made a world of difference, for our little babe (and for mom). Will be definitely be purchasing!
Alexis W.
Absolutely love! Our little babe decided around three weeks old that he didn’t need naps during the day. After trying several different sleep sacks, I bought this one and on the first day of wearing it, our little one took a 3.5 hour nap. He now takes at least two long naps a day and I couldn’t be happier. I only wish I had bought this sooner!
renee b.
Our 2 month old started sleeping longer stretches (5-6 hours) after the second night!
Sara S.
My newborn sleeps so much better and we even put it on him for car rides and he’s perfectly content the whole drive.
Hannah P.
This was a gift
Alexandra M.
I had to get the next size up! My daughter has been sleeping through the night since she was two months old!
Sarah H.
Well made good quality material. I have one bamboo and one cotton. They are both nice! My baby started sleeping through the night better and napping better with the bested bean swaddle. It made a huge difference for us.
Angela W.
This was the perfect alternative. We had used Nested Bean swaddle when baby was 0-3months old then switched to Dreamland Baby but once baby started rolling over to sleep on her stomach, we didn’t have much use for DB. Nested Bean sleep sack is so lightweight, perfect for our little nugget so she can move her legs freely without being weighed down.
Jessica B.
Helps keep baby to sleep with gentle pressure. My LO absolutely loves it!
Brittany F.
Our little girl loves it! She is only a cat mapper and at nap time it allowed her to sleep for an hour with her hands up which she loves but still contains them so they aren’t thrashing around!
Mary D.
The Zen Sack has been a game changer! My 2month old was starting to roll & get very fidgety at night. Once I popped this onto her, she was sleeping 5-6hrs at a time! It’s been an amazing life saver when it comes to sleep!!
Abby M.
My daughter is 6 months old and rolling and we put the bean part on her back and she loves it. When she first started rolling it would be on her chest and it didn't bother her at all!! I recommend these to everyone I talk to!

We have been using nested bean sleep sacks for our daughter For the last 7 months and we love it!! It help her to stay asleep throughout the entire night and she loves looking at the little chick on the front.
Joellys T.
We love our sleep sack! My baby is 8 weeks 11 pounds 26 inches long and it fits him great and he has plenty of space for growing. We have many sleep sacks this one happens to be his favorite!
Breanna S.
Cute but I haven't noticed a big difference in sleep. All babies are different, this product just didn't work as well as I'd hoped for my little guy.
Maria R.
I started using this sleep sack when my baby turned 2 months. He’s almost 4 months and from the first day I started using it he started sleeping all night. He went from sleeping 2-3 hrs at night to sleeping 7-9 hrs straight. I love it and I recommend it
Heather L.
Baby girl is sleeping so much better through the night.
Samantha B.
I unfortunately couldn’t wait to purchase from the website so I went to target. My 8 month old would cry for HOURS. When I say hours I mean with no exaggeration. I would do absolutely everything. Rocking him, feeding him, turning on white noise, the cry it out method, rubbing his belly or back. NOTHING worked. He was inconsolable. I was worried something major was wrong. Then I tried this at my last whits end. It worked the SECOND I put it on him. He slept through the night, he’s taking his regular naps, he doesn’t need to be rocked at all. He just needed this extra comfort. This product is a literal MIRACLE. Please don’t hesitate to buy this! It’s easy to change my baby, no restriction on him rolling and moving. It’s truly amazing. This is amazing for a baby shower gift, amazing last minute help, making things easier for moms that are overstimulated. I can’t say how thankful I am to find this product.
Delphine T.
Purchased for my niece who is expecting. She was thrilled to get ,writing for arrival of baby, September
Amelia P.
It hasn’t affected my daughters sleep at all. It was basically an expensive sleep sack.
Shannon C.
Just used this sleep sack with my 5 week old last night and we got the longest stretch of sleep she’s ever had (7 hours!!!). I’d give this product ten stars if I could. It’s also super easy to take on and off for changing. Love the shoulder snaps.
Victorya B.
This is our second one, and we love it!
Linda B.
Bought for a baby shower. Can’t wait to give it.
Katelyn Y.
We love the zen sack! My baby hates to have his arms swaddled and we struggled to find a sleep sack that he likes. But with the zen sack he sleeps longer stretches and really seems to like it.
Rebecca L.
My 2 month old really enjoys sleeping in her sack. She's comfortable and it's breathable.
Josie H.
I bought this for my grandson and he loves it. He is a newborn. He instantly calms then falls asleep with it in. Very durable and worth the price. The best feature is the bottom zipper so his legs can be exposed if needed as he grows. Easy on and easy off! I can’t say enough about it. A must for kiddos!
Dinora A.
We love our Zen Sack Classic in our favorite color lilac. Baby fell asleep right away for 8 hours the first night.
We like the adjustable shoulder straps
as she grows, she likes the freedom to kick her legs and the light weight on the chest, soothes her to sleep. We love it so much, we purchased another one in pink! Highly recommend it♡
Caressa G.
We love it!
Stephanie R.
We love Nested Bean. Our 8 week old has hated being swaddled from the very beginning and did ok in the hospital sleep sacks. However, she’s a growing girl and those did not last long. These are plenty big for her and the slight weight on the chest helps calm a sleet baby that only wants to be held! We get 3-4 hour stretches most nights using this sleep sack. If you’re on the fence, jump over and join us!
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.

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
Sharon G.
I bought it for my grandson who was having a difficult time transitoning to the crib. He went quickly to sleep and we discovered he is a stomach sleeper! Thank you very much!!
Danielle P.
I've used the zen sack for my two girls ! My 3 year old sleeps through the night now because we used the zen sack and sleep trained her to fall asleep on her own since she was a newborn we did this exact thing with my now 5 month old who is colic and she sleeps amazingly as well (she still wakes up but without the sack its every 3 hours with the zen sack its every 5 hours ) I can't express how much this sleep sack has helped me get a better night sleep with my babies i really wish I knew about this when I had my son 6 years ago cuz it is a big game changer ! I've even purchased the sleep sack for every single baby shower we have went to in the past 3 years and every person I've got it for has thanked me so much for it because how big of a difference it made to their babies sleep !!!!.......DO IT !!! GET IT !!! ITS NOT A SCAM IM A MOM OF 3 WHO USED IT WITH 2 OF MY 3 AND IT CHANGED MY LIFE !! I WAS A ZOMBIE WITH MY FIRST CHILD CUZ HE N3VER COULD SLEEP UNLESS HE WAS HELP THIS CHANGEDDDDDD IT ALLLLL !!!! SPEND THE MONEY !
Hillarie D.
Love the sleep sack! Super fast shipping!
Lily P.
My daughter has been wearing the classic Zen sack since she was 3 months old! She is now 1. I absolutely love it , and apparently so does she. We only use it at night, and it helps her sleep the whole night through. Happy costumer here!
Marisa W.
We love the nested bean sleep sacks! We used them with my first daughter and now with my second daughter and they are a lifesaver for us. The one thing that was odd about the pink one compared to all the other ones we have purchased was, there was a huge tag on the outside of the sleep sack that I would’ve expected to be on the inside of the sleep sack instead. I just cut them off but seemed weird none of our other ones were like that.
PAULA C.
I love the nest! Baby takes longer naps
Kaitlynn a.
My two month old has been sleeping 8 hour stretches since the first week we started wearing the zen sack. I am a true believer! My sister in law suggested buying this sack after her baby started sleeping through the night in his zen sack and I couldn’t be happier that we both are having such great success.
Isabelle G.
My baby usually twitches a LOT, which keeps her from getting a full night’s sleep, but with the weight on her chest, she gets startled less and sleeps in more; able to get full 6-8 hours of sleep!
kalynn
We absolutely love Nested Bean! Our baby has been sleeping in one since the day we brought her home and I think it plays a huge role in why she sleeps so well. She has been a great sleeper from day 1 and was sleeping through the night by 6 weeks old (probably would have sooner, but I was still waking her up for feeds). We have two of their sacks that we switch back and forth between, but she loves both. Great investment for your little one!
Emily P.
I love the quality of the sleep sack and how the buttons are on the shoulders and have the zip around the legs too! I feel like my baby didn’t notice a helpful difference with it being weighted though.
Hannah F.
This has been great so far! Baby Live sleeping on his stomach in this. He continues to sleep soundly. See less transition :)
Tobie B.
I can finally now have my sleep. With this sleep sack, my baby can enjoy having a long hour sleep. I like how the material is soft and it doesnt make my baby sweat at night. I also like how it's a easy change diaper
Tiffany N.
Truly believe the weighted bean has helped our little guy enjoy sleeping on his tummy. He would always roll over and scream. No more holding a hand on him until he falls asleep!
Holly P.
Work great
Jessica G.
My baby loves her sleep sack! She sleeps 5 hour intervals in it!!
Melissa W.
I absolutely love the quality of my sleep sack:) it’s super soft and the weight seems to be just perfect. I can’t wait to purchase the next size up once my little one grows out of the 0-6months:)!!
Madison R.
My LO loves this sleep sack! He takes longer naps and doesn’t toss and turn during his sleep anymore!
Tess
My friend gave me one of the sleep sacks to try before I purchased one as our 2 month old just hit 8lbs. She is such an active sleeper to the point where she was constantly waking herself up. I didn’t think it would make much of a difference in her sleep but man I was wrong! The weighted egg is just the right amount and keeps her settled. This is our 3rd night and it’s made a world of difference, for our little babe (and for mom). Will be definitely be purchasing!
Alexis W.
Absolutely love! Our little babe decided around three weeks old that he didn’t need naps during the day. After trying several different sleep sacks, I bought this one and on the first day of wearing it, our little one took a 3.5 hour nap. He now takes at least two long naps a day and I couldn’t be happier. I only wish I had bought this sooner!
renee b.
Our 2 month old started sleeping longer stretches (5-6 hours) after the second night!
Sara S.
My newborn sleeps so much better and we even put it on him for car rides and he’s perfectly content the whole drive.
Hannah P.
This was a gift
Alexandra M.
I had to get the next size up! My daughter has been sleeping through the night since she was two months old!
Sarah H.
Well made good quality material. I have one bamboo and one cotton. They are both nice! My baby started sleeping through the night better and napping better with the bested bean swaddle. It made a huge difference for us.
Angela W.
This was the perfect alternative. We had used Nested Bean swaddle when baby was 0-3months old then switched to Dreamland Baby but once baby started rolling over to sleep on her stomach, we didn’t have much use for DB. Nested Bean sleep sack is so lightweight, perfect for our little nugget so she can move her legs freely without being weighed down.
Jessica B.
Helps keep baby to sleep with gentle pressure. My LO absolutely loves it!
Brittany F.
Our little girl loves it! She is only a cat mapper and at nap time it allowed her to sleep for an hour with her hands up which she loves but still contains them so they aren’t thrashing around!
Mary D.
The Zen Sack has been a game changer! My 2month old was starting to roll & get very fidgety at night. Once I popped this onto her, she was sleeping 5-6hrs at a time! It’s been an amazing life saver when it comes to sleep!!
Abby M.
My daughter is 6 months old and rolling and we put the bean part on her back and she loves it. When she first started rolling it would be on her chest and it didn't bother her at all!! I recommend these to everyone I talk to!

We have been using nested bean sleep sacks for our daughter For the last 7 months and we love it!! It help her to stay asleep throughout the entire night and she loves looking at the little chick on the front.
Joellys T.
We love our sleep sack! My baby is 8 weeks 11 pounds 26 inches long and it fits him great and he has plenty of space for growing. We have many sleep sacks this one happens to be his favorite!
Breanna S.
Cute but I haven't noticed a big difference in sleep. All babies are different, this product just didn't work as well as I'd hoped for my little guy.
Maria R.
I started using this sleep sack when my baby turned 2 months. He’s almost 4 months and from the first day I started using it he started sleeping all night. He went from sleeping 2-3 hrs at night to sleeping 7-9 hrs straight. I love it and I recommend it
Heather L.
Baby girl is sleeping so much better through the night.
Samantha B.
I unfortunately couldn’t wait to purchase from the website so I went to target. My 8 month old would cry for HOURS. When I say hours I mean with no exaggeration. I would do absolutely everything. Rocking him, feeding him, turning on white noise, the cry it out method, rubbing his belly or back. NOTHING worked. He was inconsolable. I was worried something major was wrong. Then I tried this at my last whits end. It worked the SECOND I put it on him. He slept through the night, he’s taking his regular naps, he doesn’t need to be rocked at all. He just needed this extra comfort. This product is a literal MIRACLE. Please don’t hesitate to buy this! It’s easy to change my baby, no restriction on him rolling and moving. It’s truly amazing. This is amazing for a baby shower gift, amazing last minute help, making things easier for moms that are overstimulated. I can’t say how thankful I am to find this product.
Delphine T.
Purchased for my niece who is expecting. She was thrilled to get ,writing for arrival of baby, September
Amelia P.
It hasn’t affected my daughters sleep at all. It was basically an expensive sleep sack.
Shannon C.
Just used this sleep sack with my 5 week old last night and we got the longest stretch of sleep she’s ever had (7 hours!!!). I’d give this product ten stars if I could. It’s also super easy to take on and off for changing. Love the shoulder snaps.
Victorya B.
This is our second one, and we love it!
Linda B.
Bought for a baby shower. Can’t wait to give it.
Katelyn Y.
We love the zen sack! My baby hates to have his arms swaddled and we struggled to find a sleep sack that he likes. But with the zen sack he sleeps longer stretches and really seems to like it.
Rebecca L.
My 2 month old really enjoys sleeping in her sack. She's comfortable and it's breathable.
Josie H.
I bought this for my grandson and he loves it. He is a newborn. He instantly calms then falls asleep with it in. Very durable and worth the price. The best feature is the bottom zipper so his legs can be exposed if needed as he grows. Easy on and easy off! I can’t say enough about it. A must for kiddos!
Dinora A.
We love our Zen Sack Classic in our favorite color lilac. Baby fell asleep right away for 8 hours the first night.
We like the adjustable shoulder straps
as she grows, she likes the freedom to kick her legs and the light weight on the chest, soothes her to sleep. We love it so much, we purchased another one in pink! Highly recommend it♡
Caressa G.
We love it!
Stephanie R.
We love Nested Bean. Our 8 week old has hated being swaddled from the very beginning and did ok in the hospital sleep sacks. However, she’s a growing girl and those did not last long. These are plenty big for her and the slight weight on the chest helps calm a sleet baby that only wants to be held! We get 3-4 hour stretches most nights using this sleep sack. If you’re on the fence, jump over and join us!
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.
