Want to live it but it’s too big for baby right now, covers her mouth and nose.... I’ll try ordering a different style to see if that works better for a small baby!
Monica R.
I absolutely love the material of this sleepsack, super soft! However, these sleep sacks are difficult for me to get on my incredibly active son. I don’t feel like the weighted option has made much of a difference in his sleeping habits either, unfortunately. I’m not sure I would spend as much money again, I would likely opt for a less pricey brand. I wish these would have worked for us. I would have bought stock if they improved our sleep!
Alessandra B.
Great product!! This is our third one and works wonderful every time.
Cristin C.
We've liked the sleep sack! It's light weight for our hot natured baby but gives a little pressure in the important places. He still startles himself awake since his arms are out but overall I think it contributes to his sleep. My favorite feature is the super soft material.
Cynthia F.
First night of wearing our sleep sack my little one gave me 5 consecutive hours of sleep before he woke up for change and feeding, before he was only giving me 1.5-2 hours. I’m excited to see how much more sleep this magical product will help with!
Angie J.
Love the bamboo fabric. My baby doesn’t get too hot in this
Tini I.
Good
Cheryl S.
My granddaughter seems to love it.

We LOVE the Zen Sack! My son has used it from about 8-months-old to today (15 months) and his naps and bedtime sleeping is incredible! When we were transitioning from the swaddle, we tried a few different sleep sacks, but this Nested Bean one worked so much more efficiently for us than the others. We are big fans of these products and give them as gifts now!
Adriana G.
The premium is definitely a lighter feel than the classic cotton. Feels softer too. I really like the zipper going around the bottom and side instead of down the middle like other brands. Only complaint is the giant warning tag on the outside. Seems like there could be a better way to warn parents.
Denise J.
We bought this for our 2 month old and it truly did help him learn to fall asleep on his own and probably sleep longer (there are still nights he wakes up multiple times but he’s also only 2 months old, too). I like the adjustable shoulder straps and zipper for the bottom part.
Madison S.
I wasn’t able to get my baby to sleep in her crib for more then a few hours at night and not at all for naps. The first time we used this she took almost a 2 hour nap in her crib. By the 3rd night she was sleeping in her crib for all naps and through the night. This was a great investment and i definitely recommend it!
Kyle P.
I didn't notice a change immediately. He was using the Snoo bassinet and he use to sleep all night. Since the transition to his crib, he was waking up very often. This sack seem to really help him to now only waking up once or twice a night.
Stephanie C.
Great material! My baby sleeps wonderful in this sack!
Tamara G.
My daughter sleeps so much better with this ❤ it is truly amazing!
marie t.
The nested bean sleep sack definitely helps my grandson sleep better. It is so soft and comfortable and has a lightly weighted spot to help the child feel secure and comfortable. Would highly recommend this product
Fabiola G.
Baby loves it! We love it!
Raquel T.
Really cute. Great quality. Baby loves it and rubs it while soothing himself to sleep. He gets hot at night and TOC 1 keeps him cool. He is two months and loves to cuddle. Unfortunately, the weight or sack hasn’t made a difference in his sleep. I wish there were a v-neck or a lower collar. Baby does tug at it as it gets right under his neck.
Debbie W.
This sleep suit is light weight and very comfy for my 18 month old grandson. He loves it.
Kristen M.
The sack came with a tear out of the box. It’s a lot thinner than expected and hasn’t helped keep baby asleep during naps.
Valerie H.
Super cozy! And thin! It can be used all year around and we use ours any night it’s clean! We just love y’all so much I wish we could get more!!!!
Best sleeping sac ever!!!
I have a ton of pics I’ve posted on my Instagram
Mrsdrix_realreviews and done a review on y’all on there and bragged on yalls amazing product
Kalina P.
My baby girl is 2 month old. Normally she would wake up twice through the night to eat. We purchased the Zen Premier sack. Now she is sleeping 8 hours a night. It is absolutely amazing, she is falling asleep on her own, no rocking or holding her. Highly recommended.
Araceli Z.
Love all the nested beans. This is our 5th one (large now) and we keep buying the next size up or next season since our little one feels safe and snuggly inside. Even at 16 months, he won’t sleep without it. It has know turned into part of his bedtime routine.
Angela L.
I bought it for my granddaughter and my daughter loves it.
Jaclyn T.
I’ve been using this sleep sack for a few weeks and haven’t noticed a difference at all in her sleep pattern. My baby is 3 months old and regularly sleeps 3-4 hours at a time. This sleep sack has not increased her time sleeping. It’s a nicely made sleep sack, which is the only reason I haven’t returned it. Overall disappointed it didn’t work for us.
Angelica D.
My little one loves her sleep sack. The sun comes up and she still sleeps !
Mariam H.
I love your product my grandson, sleep so well because of it. Since 4 months he goes 11 hours a nite time, during the day as soon I put it he know is nap time. Is like magic.
Travis C.
Our son loves his sleep sack. Can’t sleep without it.
Ari H.
The concept is great. Our little man sleeps better with a hand in his chest. But
1) the zipper cover is a bit too small it slides off to easy so having it bigger and thicker would be great
2) he rolls around when he sleeps and the sack gets slid around and taught etc.
3) the zipper is a bit loud …but don’t know if there’s a way to make it more quiet .
4) wish they made one where it’s like a bag with feet holes so he could toodle around in it. Crawling is impossible in it so it’s strictly for bed only.
5) wish the bamboo material also in warmer options for cold weather. Eczema babies would really benefit but it’s great for summer.
Lauren W.
This is perfect for transitioning from the swaddle, my little one took right to it! It’s very nice quality and the print is so cute!
Zoraida R.
Took a few days but it seems to be working. My son can sleep a full 6 hour stretch now :). Hopefully he’ll be doing longer stretches.
Kristi C.
It’s great for warm nights. The fabric is very soft. I have to get one for when it’s colder out. I haven’t noticed too much of a difference in his sleep. It’s been almost two weeks and some days are better then the other, but no drastic difference.
Shayla J.
My twins haven’t completely gotten used to it yet but it seems so comfy and they’ve napped a bit better! Bedtime is still iffy though.
Patricia Y.
We love these sleep sacks just needed a bigger size as she grows!
Susan S.
Bought for my great grand baby.
My granddaughter total said this was the best brand. The material is so lite and soft
Jenna W.
Just like they advertise, it took a few days for our little guy to get used to this sleep sack, but I was willing to do anything since he was waking up 6+ times a night. After about a week that dropped to 2-4 times a night, and now the past two nights only 1 time towards the morning! He loves to sleep on his tummy with the weight on his back- something he hated before. I see restful nights in the near future with this sleep sack!
Skyler J.
My babygirl has been sleeping in this for naps and nighttime and we absolutely notice the “touch” difference. She’s so much more settled in her crib now!
Melissa B.
Baby Ben LOVED being swaddled and had been sleeping through the night since he was just over 1 month old. As soon as he learned how to roll over and had to get out of his swaddle, he struggled to sleep. We picked up the Zen Sack to see if that might help. He loves it! We started out with the weight on the front, but he was consistently rolling over and sleeping on top of it. It didn't seem to bother him, but we turned it around so the weight is on his back, and now he is sleeping even better. He sleeps through the night again. :)
Emily S.
I was worried this would be very girly, but it is perfect for boys as well! We love the sleep it provides also!
Wanlu b.
Runs small. My kid 5 months old 17 lb, it’s quite tight for her.
Regina R.
Material is very soft. My little one tosses and turns alot but mainly sleeps on her stomach. I started off putting the sleeper backwards but when she rolled to her back it woke her up. Guess laying on a lump was uncomfortable. I put it on the other way and she seems ok with it. Not really a difference in sleep still moves around alot. She never really woke up in the first place before these sleepers. I was just wanting her to sleep a bit more sound at night. In conclusion, I didn't really see a difference. The material is nice but that's about it.
Lauren C.
Did not change my 3 month olds sleep at all but I like the soft material.
Shaina F.
We went from a snoo to the crib recently so we bought one of these to help keep him some what wrapped up since he is zipped up in the snoo. I was afraid the “weight” would be too much and put pressure on the chest but it is very very light weight but seems to be just enough to give comfort. I also love that it is machine washable! He has done greats transferring from snoo to crib. I’m not sure if that actually helped but I’m not going to jinx it! I got the bamboo and then a cotton sleep sack. The bamboo seems much lighter and softer which i like but love that the 100% cotton is very breathable.
Erin H.
Love the light weight sleep sack for summer!! So soft for baby! Highly recommend!
Brittany M.
Have not recieved it yet
Brecken A.
This was a gift sent out of state and it was well received.
Veronica M.
Bought this to try out. I'm not sure if it actually works or if my baby is just a great sleeper. However, if a sleeper does help our baby, the Magic Merlin actually works better where baby sleeps for about 6-7 hours instead of 5-6 hrs with the Nested Bean.
Gabrielle P.
We love the nested bean sleep sack! My daughter has been wearing once since she was 4 months old! She will not sleep without it on! She went from waking up every 2 hours to sleeping 8 hours straight.
Kandi H.
Hands down a total game changer. Totally works for my 3-month old and super eady to lay flat in crib, snap him into when he's ready for a nap. He sleeps longer and the two-way zipper makes a diaper change easy and for easy access to attach his foot monitor. Bought two sacks in his current size and two more in the next size up. They wash and dry beautifully and really work for our baby.
Jessica G.
My son was waking up 2-3 times a night to be soothed. After reading parent testimonies, I decided to give Nested Bean’s sleep sack a try. My son instantly slept better after his first use. The sack is so soft and perfect for the climate I live in. Mom and Dad were finally able to achieve better sleep.
Lauren Z.
Our little one loves these sleep sacks. No adjustment period needed either. Just a great night sleep from the start. I love the premium material too. Living in a warmer climate this keeps her cool and comfy.
Jazmine R.
The material is amazing. Love it.
Tammy S.
Our daughter LOVES these sleep sacks! They comfort and are perfect in every way! She grabs it and her paci when it’s time for bed! ;)
Stacy G.
Love it!
Ashley B.
Amazing sleep sack and a nice soft lightweight fabric for summer.
Brittney N.
We have loved our Nested Bean sleep sack since my son was 4.5 months old and he is now 13 months old still loving it. I love the penguin pattern on this one and it is SO soft. My son sleeps like a champ in his (as noted in the picture). We put the weighted part on his back since he is mostly a belly sleeper. Very pleased!
Sherri W.
Baby slept pretty well transitioning from the swaddle- he only woke a couple times. And it’s super cute! My only complaint is that it already has a hole in it and I’ve only washed it a couple times.
Payal R.
Love this sleep sack - nice and lightweight for a warm California summer!
Laura O.
I love this brand! My baby sleeps wonderful in all of these!
Whitley K.
We love our sleep sack! She sleeps great with it! No more wiggling for our little one through the night.
Katie H.
Once we put little man the Nested Bean sleep sac, he’s been sleeping through the night since the very first night!!
He’s almost 4 months old & for months now he’s a fantastic independent sleeper & wakes up the happiest baby in the world!! He’s a mover & a shaker in that crib & absolutely loves his premier penguin sleep sack! Not to mention the Nested Bean customer service team is INCREDIBLE with any big or small questions you may have. I recommend this on all mom social media groups & to my friends & I truly can’t say enough great things :)
Mia C.
I love this sleep sac! Once my son started turning over on his own I needed to find something safe for him to sleep in as he was used to being swaddled very tight every night. It only took a few days but my boys sleeping great! 12 hours each night at 5 months old and only wakes once at night
Lauren A.
Seems to work well for my little one so far. He gets around 6-8 hrs of sleep at night as long as he isn't hungry ;)
Brooke H.
Love the nested bean zen sack! We got the winter one for my daughter first, which we loved! Just recently switched to the premium bamboo for the warmer weather and she doesn’t sleep a night without it! Def feel like it helps to keep her feeling cozy
Laura F.
Love the bamboo sleep sack for summer time! Thinner material, but still makes my little one feel secure and cozy.
Raina C.
Helps my baby stay asleep after I put her down!
Nicole D.
Bought this product before just needed a bigger size. Love it like the smaller one I had.
Caroline C.
So unlike the many other lucky parents my little one is still adjusting to it. She doesn’t sleep through the night... she does exact what she did with the swaddle.. I actually find it she wakes up more often. I knew I should have kept the box to return but I was so hopeful that I threw the box away. I want to give it a chance so my review isn’t a one star... 4 days and still going... let’s see what happens.
Alexandra N.
The fabric is really soft, the sleeping bag is well fitted and super cute. My son didn’t sleep more with it but he is generally a good sleeper.
Maureen R.
Our little one loves to have have her arms out to self soothe by sucking on her fingers, so this product has been great as she transitions out of a swaddle. She also has much more leg room in this product verse other options. The material is super soft too!
Linda S.
Haven't really noticed a different sleeping pattern as a result.
Emily T.
We were gifted the Original Swaddle when our baby was about 7 weeks old and I so wish we had found NestedBean earlier! As a FTM, I’d been nervous about the weight of the beans, but it is so lightweight and our little one started sleeping better instantly! We bought the Zen Sack Premier sleep sacks for 0-6 months and 6-15 months when he grew out of the former. Our babe is very long and grew out of 0-6 lengthwise around 4 months, but he sleeps so well in the new one. Customer service has been great when we had issues with shipping in one of our orders.
Kyscha O.
This is amazing! My newborn wasn’t sleeping through the night & would wake up every 2-3 hours so I’d be exhausted. This has been a life changer because my baby now sleeps through the night!
Jessica C.
We love the it. However it be better is we could get the 6-15? Month in a longer sized option. The 15-24 is to baggy on her and she doesn’t sleep well in them. Love how soft the premiere option is though
David S.
My 8 month old still doesn’t sleep more than an hour at a time. We have tried absolutely everything and been to doctors to see if something else was the problem but we were told she is just a very light sleeper. There is nothing wrong with tour product just doesn’t make any difference with my child versus any sleep sack
KRISTA W.
Love the nested bean sleep sack. We currently have 2 varieties. The bamboo collection one is super soft and the foxes are just adorable.
Katie H.
Within 2 minutes (no joke) little man is knocked out every time we put his sleep sack on him! This is hands down one of the best newborn purchases you could make. He went from waking up twice in the night to sleeping through the night within the first use!!! He now sleeps through the night every night. Little buddy turned 3 months old yesterday & slept 11 hours... need I say more!
javiera c.
My 10 weeks old baby loves it and sleeps all the time with it . Once I put it on she knows is nap/bed time
BROOKE T.
I swaddled my little man since the day he was born and he slept through the night since 4 weeks old, but once he started rolling and we stopped swaddling he was up every 1.5 hours. Tried the Zen sack and by night 3 he was back sleeping through the night! Just ordered another!
Jolene S.
This sleep sack is a absolute must have! I love everything about it! Your baby will sleep so well! I recommend it to every mama I know!
Chandler L.
I purchased this sleep sack for my 8-month old as an alternative to a more weighted, warmer sleep sack that had a zipper at the top right under my baby's chin. She was constantly chewing on it and scraping the paint off, which worried us. I was nervous that the Zen sack wouldn't be weighted enough for her and would potentially cause some night-waking, but no such thing happened. She still sleeps 10-11 hours at night with no issue and loves to turn on her side and kick her legs up while in the sack. Turns out the weight at the chest is all she really needs! Love that this snaps at the shoulders so she doesn't have much to chew on. Also love the bamboo light-weight aspect considering we live in a place that gets hot during the summer.
Very happy with my purchase and have recommended to others! 6-15 months fits her well and she has plenty of room to grow.
Joyce E.
Love the quality!
Melody A.
On the first night of using nested bean my 3 month old son was able to sleep 5 full hours compared to every 3 hours.
Jessie S.
I have bed shared with my 7 month old since birth! It was not working for me anymore so I decided to transition her to her own sleep space. It was difficult...until we got her the Nested Bean Zen sleepsack! She has slept 11 hours in her crib at night for the past 10 days straight and we are all thrilled! We live in AZ so I purchased the lightweight bamboo option and so far it works great. We love it. I need to buy more
Samantha S.
Like the product but the color bled during the first wash so the shoulder straps are all dyed and mess and the back as well. 3/5
Miki M.
It seems to be of high quality but doesn't seem to help my LO sleep. Wish it was a bit heavier. Love the penguin pattern
Kelly R.
Was very skeptical that our 3 month old would sleep through the night the first night being unswaddled in his zen sack. He woke up twice but I never had to pick him up to get him back to sleep. The zen sack is so soft and lightweight that even his hot natured body was perfectly comfortable even in a sleeper. So happy with this purchase and have bought some as gifts.
Stephanie W.
I bought the 6 - 15 month size. It’s tight on my 5 month old.
Carla M.
Got zen sacks for both of my grandbabies and I love them
Craig M.
My toddler sleeps so well with this!
Alina H.
Great product
Shannon B.
Super soft!!!! It’s my favorite one and I have 3 different ones.
Joyce S.
I ordered this while sleep training, but didn’t get to use it. My LO quickly learned how to role on her tummy in the process of sleep training, and now exclusively sleeps this way. She cannot role back onto her back yet, so we don’t want to reverse the nested bean with the weighted section on her back. Maybe when she is older and stronger we will try again with this product, but for now we don’t use it.
CHRISTINE M.
My grandson is finally sleeping better
Kristal V.
My grandbabies use these at night and they love them. They sleep so good with the light weight provided by the sleep sack. We have bought multiple sacks in a variety of fabrics. Recommend highly.
Emily T.
Our little one has never been a good sleeper, but it was time to end the swaddle and I was desperate for anything that would help. The reviews of the weighted sleep sack were all amazing, so I thought it might be too good to be true. But we ripped off the band-aid, and though the first night was pretty tough, by the second she was sleeping in four hour blocks instead of two. Plus, we love the fox pattern and the fact she can use this sack for the next year, if she needs it!
Samantha M.
The material is super soft and the colors are bright and beautiful! Our 13 month old loves her NB sleep sacks!
Marie-Claude R.
Love it !
Megan M.
Love our Nested Bean! Went from 4-5 hour stretches of sleep to 9-10 hour stretches in less than 2 weeks!

Want to live it but it’s too big for baby right now, covers her mouth and nose.... I’ll try ordering a different style to see if that works better for a small baby!

Material is very soft. My little one tosses and turns alot but mainly sleeps on her stomach. I started off putting the sleeper backwards but when she rolled to her back it woke her up. Guess laying on a lump was uncomfortable. I put it on the other way and she seems ok with it. Not really a difference in sleep still moves around alot. She never really woke up in the first place before these sleepers. I was just wanting her to sleep a bit more sound at night. In conclusion, I didn't really see a difference. The material is nice but that's about it.

Did not change my 3 month olds sleep at all but I like the soft material.

We went from a snoo to the crib recently so we bought one of these to help keep him some what wrapped up since he is zipped up in the snoo. I was afraid the “weight” would be too much and put pressure on the chest but it is very very light weight but seems to be just enough to give comfort. I also love that it is machine washable! He has done greats transferring from snoo to crib. I’m not sure if that actually helped but I’m not going to jinx it! I got the bamboo and then a cotton sleep sack. The bamboo seems much lighter and softer which i like but love that the 100% cotton is very breathable.

Have not recieved it yet

This was a gift sent out of state and it was well received.

Bought this to try out. I'm not sure if it actually works or if my baby is just a great sleeper. However, if a sleeper does help our baby, the Magic Merlin actually works better where baby sleeps for about 6-7 hours instead of 5-6 hrs with the Nested Bean.

We love the nested bean sleep sack! My daughter has been wearing once since she was 4 months old! She will not sleep without it on! She went from waking up every 2 hours to sleeping 8 hours straight.

Hands down a total game changer. Totally works for my 3-month old and super eady to lay flat in crib, snap him into when he's ready for a nap. He sleeps longer and the two-way zipper makes a diaper change easy and for easy access to attach his foot monitor. Bought two sacks in his current size and two more in the next size up. They wash and dry beautifully and really work for our baby.

My son was waking up 2-3 times a night to be soothed. After reading parent testimonies, I decided to give Nested Bean’s sleep sack a try. My son instantly slept better after his first use. The sack is so soft and perfect for the climate I live in. Mom and Dad were finally able to achieve better sleep.
Lauren Z.
Our little one loves these sleep sacks. No adjustment period needed either. Just a great night sleep from the start. I love the premium material too. Living in a warmer climate this keeps her cool and comfy.
Jazmine R.
The material is amazing. Love it.
Tammy S.
Our daughter LOVES these sleep sacks! They comfort and are perfect in every way! She grabs it and her paci when it’s time for bed! ;)

Love it!

Amazing sleep sack and a nice soft lightweight fabric for summer.
Brittney N.
We have loved our Nested Bean sleep sack since my son was 4.5 months old and he is now 13 months old still loving it. I love the penguin pattern on this one and it is SO soft. My son sleeps like a champ in his (as noted in the picture). We put the weighted part on his back since he is mostly a belly sleeper. Very pleased!
Sherri W.
Baby slept pretty well transitioning from the swaddle- he only woke a couple times. And it’s super cute! My only complaint is that it already has a hole in it and I’ve only washed it a couple times.
Payal R.
Love this sleep sack - nice and lightweight for a warm California summer!
Laura O.
I love this brand! My baby sleeps wonderful in all of these!
Whitley K.
We love our sleep sack! She sleeps great with it! No more wiggling for our little one through the night.
Katie H.
Once we put little man the Nested Bean sleep sac, he’s been sleeping through the night since the very first night!!
He’s almost 4 months old & for months now he’s a fantastic independent sleeper & wakes up the happiest baby in the world!! He’s a mover & a shaker in that crib & absolutely loves his premier penguin sleep sack! Not to mention the Nested Bean customer service team is INCREDIBLE with any big or small questions you may have. I recommend this on all mom social media groups & to my friends & I truly can’t say enough great things :)
Mia C.
I love this sleep sac! Once my son started turning over on his own I needed to find something safe for him to sleep in as he was used to being swaddled very tight every night. It only took a few days but my boys sleeping great! 12 hours each night at 5 months old and only wakes once at night
Lauren A.
Seems to work well for my little one so far. He gets around 6-8 hrs of sleep at night as long as he isn't hungry ;)
Brooke H.
Love the nested bean zen sack! We got the winter one for my daughter first, which we loved! Just recently switched to the premium bamboo for the warmer weather and she doesn’t sleep a night without it! Def feel like it helps to keep her feeling cozy
Laura F.
Love the bamboo sleep sack for summer time! Thinner material, but still makes my little one feel secure and cozy.
Raina C.
Helps my baby stay asleep after I put her down!
Nicole D.
Bought this product before just needed a bigger size. Love it like the smaller one I had.
Caroline C.
So unlike the many other lucky parents my little one is still adjusting to it. She doesn’t sleep through the night... she does exact what she did with the swaddle.. I actually find it she wakes up more often. I knew I should have kept the box to return but I was so hopeful that I threw the box away. I want to give it a chance so my review isn’t a one star... 4 days and still going... let’s see what happens.
Alexandra N.
The fabric is really soft, the sleeping bag is well fitted and super cute. My son didn’t sleep more with it but he is generally a good sleeper.
Maureen R.
Our little one loves to have have her arms out to self soothe by sucking on her fingers, so this product has been great as she transitions out of a swaddle. She also has much more leg room in this product verse other options. The material is super soft too!
Linda S.
Haven't really noticed a different sleeping pattern as a result.
Emily T.
We were gifted the Original Swaddle when our baby was about 7 weeks old and I so wish we had found NestedBean earlier! As a FTM, I’d been nervous about the weight of the beans, but it is so lightweight and our little one started sleeping better instantly! We bought the Zen Sack Premier sleep sacks for 0-6 months and 6-15 months when he grew out of the former. Our babe is very long and grew out of 0-6 lengthwise around 4 months, but he sleeps so well in the new one. Customer service has been great when we had issues with shipping in one of our orders.
Kyscha O.
This is amazing! My newborn wasn’t sleeping through the night & would wake up every 2-3 hours so I’d be exhausted. This has been a life changer because my baby now sleeps through the night!
Jessica C.
We love the it. However it be better is we could get the 6-15? Month in a longer sized option. The 15-24 is to baggy on her and she doesn’t sleep well in them. Love how soft the premiere option is though
David S.
My 8 month old still doesn’t sleep more than an hour at a time. We have tried absolutely everything and been to doctors to see if something else was the problem but we were told she is just a very light sleeper. There is nothing wrong with tour product just doesn’t make any difference with my child versus any sleep sack
KRISTA W.
Love the nested bean sleep sack. We currently have 2 varieties. The bamboo collection one is super soft and the foxes are just adorable.
Katie H.
Within 2 minutes (no joke) little man is knocked out every time we put his sleep sack on him! This is hands down one of the best newborn purchases you could make. He went from waking up twice in the night to sleeping through the night within the first use!!! He now sleeps through the night every night. Little buddy turned 3 months old yesterday & slept 11 hours... need I say more!
javiera c.
My 10 weeks old baby loves it and sleeps all the time with it . Once I put it on she knows is nap/bed time
BROOKE T.
I swaddled my little man since the day he was born and he slept through the night since 4 weeks old, but once he started rolling and we stopped swaddling he was up every 1.5 hours. Tried the Zen sack and by night 3 he was back sleeping through the night! Just ordered another!
Jolene S.
This sleep sack is a absolute must have! I love everything about it! Your baby will sleep so well! I recommend it to every mama I know!
Chandler L.
I purchased this sleep sack for my 8-month old as an alternative to a more weighted, warmer sleep sack that had a zipper at the top right under my baby's chin. She was constantly chewing on it and scraping the paint off, which worried us. I was nervous that the Zen sack wouldn't be weighted enough for her and would potentially cause some night-waking, but no such thing happened. She still sleeps 10-11 hours at night with no issue and loves to turn on her side and kick her legs up while in the sack. Turns out the weight at the chest is all she really needs! Love that this snaps at the shoulders so she doesn't have much to chew on. Also love the bamboo light-weight aspect considering we live in a place that gets hot during the summer.
Very happy with my purchase and have recommended to others! 6-15 months fits her well and she has plenty of room to grow.
Joyce E.
Love the quality!
Melody A.
On the first night of using nested bean my 3 month old son was able to sleep 5 full hours compared to every 3 hours.
Jessie S.
I have bed shared with my 7 month old since birth! It was not working for me anymore so I decided to transition her to her own sleep space. It was difficult...until we got her the Nested Bean Zen sleepsack! She has slept 11 hours in her crib at night for the past 10 days straight and we are all thrilled! We live in AZ so I purchased the lightweight bamboo option and so far it works great. We love it. I need to buy more
Samantha S.
Like the product but the color bled during the first wash so the shoulder straps are all dyed and mess and the back as well. 3/5
Miki M.
It seems to be of high quality but doesn't seem to help my LO sleep. Wish it was a bit heavier. Love the penguin pattern
Kelly R.
Was very skeptical that our 3 month old would sleep through the night the first night being unswaddled in his zen sack. He woke up twice but I never had to pick him up to get him back to sleep. The zen sack is so soft and lightweight that even his hot natured body was perfectly comfortable even in a sleeper. So happy with this purchase and have bought some as gifts.
Stephanie W.
I bought the 6 - 15 month size. It’s tight on my 5 month old.
Carla M.
Got zen sacks for both of my grandbabies and I love them
Craig M.
My toddler sleeps so well with this!
Alina H.
Great product
Shannon B.
Super soft!!!! It’s my favorite one and I have 3 different ones.
Joyce S.
I ordered this while sleep training, but didn’t get to use it. My LO quickly learned how to role on her tummy in the process of sleep training, and now exclusively sleeps this way. She cannot role back onto her back yet, so we don’t want to reverse the nested bean with the weighted section on her back. Maybe when she is older and stronger we will try again with this product, but for now we don’t use it.
CHRISTINE M.
My grandson is finally sleeping better
Kristal V.
My grandbabies use these at night and they love them. They sleep so good with the light weight provided by the sleep sack. We have bought multiple sacks in a variety of fabrics. Recommend highly.
Emily T.
Our little one has never been a good sleeper, but it was time to end the swaddle and I was desperate for anything that would help. The reviews of the weighted sleep sack were all amazing, so I thought it might be too good to be true. But we ripped off the band-aid, and though the first night was pretty tough, by the second she was sleeping in four hour blocks instead of two. Plus, we love the fox pattern and the fact she can use this sack for the next year, if she needs it!
Samantha M.
The material is super soft and the colors are bright and beautiful! Our 13 month old loves her NB sleep sacks!
Marie-Claude R.
Love it !
Megan M.
Love our Nested Bean! Went from 4-5 hour stretches of sleep to 9-10 hour stretches in less than 2 weeks!
Frequently asked questions
-
How much weight is in the Zen Sack™?
The Zen Sack features a self-contained Cuddle Pad™, which weighs just 30 grams (Small size) 60 grams (Medium size) and 90 grams (Large size and distributed across the chest). Our products adhere to American Academy of Pediatrics (AAP) physiotherapy standards and Guidelines for Safe Sleep, which recommends a weight-to-body ratio of 1:10. Our product is safely weighted in key areas as opposed to all-weighted sleepwear or weighted blankets, which the AAP has deemed unsafe for infants.
-
What’s the difference between Classic, Premier, and Winter Zen Sack™ products?
The only difference between these Zen Sack products is the fabric used for construction. Classic Cotton is made from 100% breathable cotton. The Premier Bamboo is made from 70% rayon from bamboo for luxurious softness and 30% cotton for strength. Light-weight fabric, perfect for warmer climates. Bamboo is naturally anti-microbial and moisture wicking for dry, clean comfort. The Winter Cotton is made from 100% cotton and heavy poly-fiber filling. Our warmest option is perfect for cooler rooms or colder weather.
-
Is the Zen Sack safe for babies who roll over?
The Zen Sack was designed for rollers and tummy sleepers. It helps babies get longer, more peaceful sleep through all growth stages. The Cuddle Pad™ on the front of the Zen Sack is so light and flexible, it nearly flattens when baby rolls to their tummy. The sleep sack can also be reversed and worn backwards for tummy sleepers who roll independently, placing the gently weighted center on baby's back for continuous comfort through the night.
Put sleep disruptions to bed with the Zen Sack™
Seamlessly transition from swaddling
When rolling starts, swaddling stops—and some babies miss their cozy swaddle. Prevent wakeups with the gently weighted Zen Sack: So soothing, but tummy sleeper safe.
Stop sleep regressions
Rolling, sitting up, teething: New milestones can mean sleep regressions. Add the gently weighted Zen Sack to your sleep routine to help create positive associations with bedtime.
Help baby sleep through the night
Nighttime wakeups? The gently weighted Zen Sack is so comforting, it helps babies self-soothe—so they fall back to sleep on their own.
