Nice
Kristen B.
This helped us get through sleep regression, transitioning to the crib, and establishing nap time! Now it’s always part of our bed time routine. We never could swaddle because little one moves so much in her sleep. My baby doesn’t mind zen sacks at all because she can still move around- arms and legs! We just ordered a winter sack for the cooler weather and I’m excited for her to be cozy. :)
Nicole W.
It’s okay. Hasn’t helped my kiddo any
vanessa M.
My daughter sleeps so much better in this sleep sack. The shipping is also very fast!
Valerie H.
I wish I would have known about nested bean when my baby was a newborn because truly we use our nested bean sleep sacks every single night if I could have 20 of these things I promise I would get them they are my very favorite and they truly do exactly what they say!!!they have got my baby to where he was sleep in his bassinet all I have to do is lay him in it as long as he has his sleep sack on and he’s good to go I absolutely love this brand!!! We have the t-shirts, the original, and the giraffe prints (which is all season wear they are thin so you can wear in the summer or enough room where you can layer!) wish I could get me a winter one and I would have one of the all!!!!! I loveeeeeee my nested bean so much that I literally have told the drs about them and all my friends and no one heard of them, until I mentioned it! These things are like gold truly when it comes to mommies rest and a rested baby!!!!
Laura S.
This was night 6 of using the sack and she falls asleep so fast with it! My baby girl is a very active sleeper that moves a lot throughout the night but with the sack she seems to be much more relaxed when she sleeps. She only wakes up onceavo eat when she used to wake up twice or even three times sometimes! I recommend this to anyone for sure!
Deidra W.
We’ve used nested bean since 2 weeks old!!!! My boy loves them :)
L S.
I bought 1 - kyte, nested bean, and sleepnea. They're all +/- I like nested bean for the fact that the zipper isn't under the chin! The buttons that strap over the shoulders made this my favorite. But tbh idk if the weighted bean made any difference. I have my girl in all 3, but if I had to buy all of only 1, I'd stuck with just NB
Rhianon T.
Our son has always had a hard time sleeping through the night. Since I have bought this sack it’s been amazing! Our son sleeps longer and even had his first full night sleep since he was born. He learned how to roll around so he likes to sleep on him belly and I’m glad I can flip it. The zippers help the midnight diaper changes a breeze! I can not wait to order the winter sack!
Katie C.
Very nice quality, cute, sleep sack, however it didn't help my baby sleep any better. We still use it though because it is nice and very well made. I just don't think there is a magical sleep sack for our baby!
Leah N.
Baby is sleeping 6-7 hours straight throughout the night consistently! This sack is a lifesaver!
Taylor W.
My baby was one month old when I got the nested bean sleeping in 2-3 hour stretches. Now she will sleep the first half of the night for five hours then wake up to eat and wake up every three hours after that.
Kaltrina H.
Material is good , looks very pretty… My daughter didn’t help , she still awake every 2 hours!
Morgan C.
Our little one is transitioning from swaddle to sleep sack. We tried this and she still gets fussy and doesn’t sleep as well with this sleep sack, but she is still learning. The nested bean sleep sack is great quality, has the perfect amount of weight, and shipped as expected. I’m hoping in the future, as she gets use to not being swaddled, she can enjoy this more!
Jenny D.
I like this style wearable blanket with the snaps at shoulders and two-way zipper. Unfortunately the weighted egg did not work regarding helping my little one sleep. We get some 3, 4, 6 hour nights but mostly 1-2 hours; nothing consistent. Despite that I still like this wearable blanket. And, customer support was very helpful in exchanging a 3-6 mo blanket for this size. I bought the bundle but my little one grew so fast he was just about out of 3-6 mo when they arrived. It’s a nice, safe blanket and pretty cute. Would recommend and can’t hurt to try.
Norma H.
Our grandbaby loves it!
Crystal T.
I love Nested bean. It helped my daughter stay asleep through the night and I was able to get a full nights sleep. Now I buy these as gifts so other mommas can benefit from it as well. Thank you
Alyson K.
My son went from waking up 4 times a night to only 1 or 2 times. We have only been using it for about 2 weeks. I am looking forward to more continued use and him maybe even sleeping more!
Carmen B.
Extremely impressed with how well made it is! Love it!
Kate S.
My little one enjoys her sleep sack! She just started rolling over so we transitioned her from her bassinet to her crib. The transition was seamless with her sleep sack!
Elisa M.
He slept 7 hours last night!
Amy S.
It’s not helping my 2.5 month old sleep, she has been having a regression wearing it but it keeps her warm and we aren’t giving up with it yet! It worked great for my 3rd so giving it another week or two. Will update then
Laura G.
Absolutely love the zen sleep sack! I got one for both of my 3month twins and it’s made a huge difference in their quality of sleep at night. Highly recommend.
Stephanie B.
I found the sack short in length. My son was 9 months so I got the 6-15 month sack since he is a very average size for his age. He's almost too tall for it (and he is not tall by any means, he's usually in the 30th percentile for length when we take him into the doctor) and that is with the snaps adjusted as long as they can be. It's just slightly annoying that I can't use it as long as I thought. I would have bought the larger size if I'd known. For how much I paid for it I was hoping to get a good 6 months use out of it instead of maybe 2. Otherwise he seems to like it!
Megan S.
I love this sleep sack. My son has always been a cosleeper with my fiancé and me, so I decided to get him this sack specifically so we can convert him to his own crib. He goes down with about 10 minutes of fussing, but remember we are converting him. He did take a nap for 3 hours with this sleep sack on. When we didn’t have it, he only slept for two hours. It’s very soft and just a little bit thick
Linnea S.
My daughter falls asleep like a light such an amazing product
Alexandra V.
My son loves his zen sleep sack but the quality of the one recently sent to me was poor in comparison to the ones I have received in the past (photo attached).
Megan T.
Love these for security & warmth for my little one.
Janell P.
My daughter went from taking 20-30 minute naps to 1-1.5 hour naps!! All in just a couple of days!
KATIE Z.
Sleeps through the whole night since we started using Nested Bean!! Was an easy transition from the swaddle to the sack. Didn’t miss a night of sleep. We love nested bean!!
Celina H.
My little guy refused to sleep in his bassinet, we tried every kind of swaddle we possibly could, HALO sleep sacks, etc and NOTHING would make him feel comfortable enough to sleep in the bassinet (I know babies do best when being held but this mama was DESPERATE). After a few nights of consistent use with the sleep sack, he now sleeps 4 hour stretches in his bassinet EVERY NIGHT! I am so happy we gave this a shot!
KLAUDIA S.
This sleeping zen sack haven’t helped my baby to sleep longer or better unfortunately. I've been using it for two weeks and there are no changes at all. The longest nap my daughter will take in the sleeping zen sack is 15 minutes not longer, also during the night she keeps waking up to 5 times. I'm happy with the material, is very nice and comfortable and keeps my baby worm, and I don't need to worry that she will cover herself during the night while she sleeps in her crib.
Leigh R.
Selling sleep solutions to overtired desperate parents is almost too easy. I bought this sack for my 14 month old going through a 2 week (seemed forever) sleep upset. We had 2 second hand nested beans size M but he outgrew those. This L one seems to not to have the same effect (comparing a night with and without) He is sleep trained. However! Would recommend to use during sleep training. Other than that great quality cotton sack for everyday use. Can put it on and off in 10 seconds or less.
Christine H.
The best sleep sack for our little one.
Kandi S.
My LO enjoys the nested bean quite a bit. I do wish the sleep sack was 2 inches longer. I feel like I have to keep yanking the fabric down so he has room to wiggle his feet. He is 11 weeks but I guess he is a little tall. Other brands are longer so I rotate with those as well. Also, I ordered 2 of these sleep sacks and one of them has the rediculously long tags sewn on the outside of the garment instead of on the inside.
Haley D.
My son LOVES this sleep sack! When transitioning him out of the swaddle, this is the only sleep sack he would actually sleep in. He’s now 6 months and we needed the bigger size. Such a great purchase!
Carly B.
Our daughter would sleep all night swaddled, but when she started to roll and we had to remove her arms from her swaddle, she was not happy and couldn’t seem to stay asleep. We purchased the nested bean sleep sack and she immediately began sleeping through the night again! She loves it!
Xorica P.
The sack has really helped my 2 month angel fall asleep calmly. Best investment I've ever made!
Meghan R.
Hello! We have been HUGE fans of the sleep sack. Our daughter is literally obsessed and wears it almost 24/7. She is going to be a sack race champion. We have bought 6,7,8 maybe? We LOVE them but my rating is based on the change of the tag color. Our daughter noticed and is NOT a fan. It is now “new sack” because she can tell a difference regardless, can’t recommend nested beam enough!
Erin F.
This is a really well made product. I like the way it unzips, the fabric, its ability to reverse and the easy snaps, but it hasn't worked the magic for us that it seems to have for other parents. He's not sleeping through the night. He's not even really sleeping better. Really wish it had worked.
Lyndsey S.
My 4 month old loves it! He sleeps in it every night!
Jean R.
Bought as a gift and recipient loves it!
Danielle
Definitely worth the money! We started using it on our 7 week old because he was wiggling out of all his velcro swaddles. Within the first 3 days, he went from waking up every 3 hours to sleeping for 7 hours straight! What a game changer! We have been using them for 3 weeks now, and he consistently sleeps for 7-7.5 hours, followed by another 2-4 hour stretch. We switched from arms-in swaddles to these arms-out swaddles on the first day without issue, but they also sent instructions on how to transition them if they need more time. So glad we tried these! I highly recommend these!
Carol W.
Its a good sleep sack. It took a little getting used to. Putting it on, I prefer the zip up in the front sleep sacks better honestly.
Sara C.
High quality product! My 4 month old daughter will sleep 7-9 hour stretches at night!!!
Shannon M.
Was thinner than I expected and ripped when I attempted to remove the very large tag from the sleep sack.
Melissa Z.
We absolutely love the Nested Bean sleep sack. Our daughter has been using these sleep sacks since we stopped swaddling her at 4 months old, and is now 7 months old and still sleeps great! The fabric is so soft and very comfortable against her body, and washes very well too. Highly recommend. We have 4 of them now, to always have a clean one on hand.
Ashley R.
Love love these sacks
Casey V.
My little one loves his sleep sack! He sleep great with it.
Krista P.
I love all of your products!! My 8 week old sleeps so good!!! I have tried at least 5 different swaddles and your brand is by far THE BEST!!
Haven H.
We are on night 5 of our zen sack and I absolutely love it! Wish I would have had these for my two older ones!
monique r.
My 2 month old has been sleeping all night within the second day of use.. he goes to sleep around 9:30-10 and awakes about 5:30-6. We have seen a tremendous difference
Priyanka P.
First night in his sleep bag and he’s sleeping through! I am loving it!!
Valerie H.
I absolutely love the nesting sacs! If I could have one for every single day I would! My baby gets soooo cozy in them and even my older baby loves them too. I’ve posted a ton of pics on my insta as well of my baby in there’s
Mrsdrix_realreviews
And I’ve mentioned to everyone THEY NEED ONE NOW
Rachel F.
I chose this sleep sack for my daughter when she transitioned out of her swaddle at 4 months. I chose it because of all the rave reviews I saw. It took 4 days for her to adjust to her arms being free. She sleeps better with this sleep sack than she did with the swaddle! We went from 6 hours of no wake sleeping to 9 hours of no wake sleeping. I will recommend this to any parent! Great purchase.
Ashley R.
Absolutely love these sleep sacks! I was given my first nesting bean sleep sack at my baby shower, as a first time mom I was terrified to swaddle my baby in a blanket… he wiggled so much! I was scared it would’ve come lose in his sleep and could’ve been a hazard.. but with the nesting bean sleep sack I can rest better knowing my baby is warm and cozy in a safe sack! Ive already bought another on my own and plan on getting one each time he grows out of one ❤️
Melissa M.
My daughter loves her sleep sack! Not only does she sleep longer, she now identifies her sack with sleeping time and starts self soothing as soon as we put her in it. Couldn't love this product more. Wish I had known about it when my older kids were babies.
Amanda D.
I got this for my granddaughter. Her Mom will not let her have a blanket for fear that she will strangle herself. So this is the perfect solution. My daughter loves it. My granddaughter will arrive in October.
patricia p.
Love it
Kasie B.
Our son would not sleep in his crib after the bassinet transition. Once we got these sleep sack he now sleeps all through the night with no issue. We love it!!
Melissa T.
My son loves this sleep sack. He's a NICU baby and is used to being swaddled so now that he's a bit older he's not needing as tight as a swaddle and the weight on his chest is perfect to help him fall asleep.
Danica Kristl D.
Helps my LO sleep longer. Will definitely purchase another one. I just wish that it is longer. My LO is kind of average height and on the light side and I feel like he’s already outgrowing the medium.
Julia S.
My son loves the sack and sleeps so well and through the night
Misti S.
My son has worn it 6 times and slept through the night once not sure if it's working for us.
Veronica T.
I started using the nested bean sack when my daughter was 3 months old.. it helped her sleep through the night! I decided to use a regular sleep sack when I noticed her sleep pattern was consistent as grew out of the bean. Then the 10 month regression hit.. I knew that I needed to buy it again in her size. It worked almost instantly! I can’t thank the Nested Bean enough for creating such magic! I can finally sleep again!!
Erin H.
This hasn’t worked that well for us. Haven’t seen much of a change with the sleep of our 3 mo. old.
Gabriela G.
I was super excited to try this product in hopes it would help my little one sleep better. There was no change in sleep. I tried having my little one wear it for bedtime and nap times. It is super soft and easy to put on and take off. He continues to use it for comfort but no change in sleep.
Courtney T.
I was honestly skeptical. There are so many products that promise results and don’t deliver, but this one is LEGIT! I had so much trouble putting my little one down to sleep, but now when it’s bedtime I literally feed him, change him, and put him in the bag. He does a little shuffle and falls right asleep! He also is able to soothe himself when he wakes up without me helping him, which is something I’ve never experienced with any of my kids! I can’t recommend this product enough!
Olivia W.
My daughter loves it!
Jacqueline O.
Great!
Melissa H.
My son is staying asleep longer.
Morgan S.
Hasn't made any difference to my child's sleep unfortunately
Is a good quality sleeping bag though. But cost me a lot to ship overseas.
Will keep trying to see if it makes any difference
Rachel S.
Love this one because it has weighted beads spread out all over the chest piece instead of just the center circle in the previous size(6_12 months)...it works better for my LO since she's a tummy sleeper.
Gisselle G.
I love the zack since I bought this my daughter sleep straight between 6-7 hours so happy about it.
Thank
Lynelle M.
I need another will order soon
Samuel H.
We've had it for about a month now, we use it every night for our 11 month old, she was waking up about 3 to 4 times a night maybe less, the past couple of weeks, she'll wake up 1 or 2 times a night now, so I guess it's working some what.
Ilse M.
When we first bought it we thought it would be your “average” sleeping sack but he slept through the night the first day we got it!! I haven’t slept a full 7+ hours since he was born (he’s almost 10 months) and now I get to have my sleep back!! I trust Nested Bean with my SLEEP lol I’m always recommending it to my mommy friends as well.

We had the smaller size but as my daughter got bigger we have to get the bigger size. We love it!! And she seems to love it also. The customer service is AMAZING!
Alondra B.
Love this sleep sack! Best thing to happen to us as first time parents little one sleeps so comfy and helps prevent her getting stuck in between crib bars!
Trinh N.
It didn’t work for our 5 months baby. She still wake up every 3 hours for feeding. I was really hoping it would help because we had tried so many different brand.
Dean D.
Weighted sleep sack doesn't seem to help my baby get to sleep any quicker or stay asleep any longer. In hindsight, I wish I would've bought twice as many normal sleep sacks to have more in rotation while others are being washed. Hopefully this helps other babies, but I don't feel the added cost was worth it for mine.
Nadia P.
Nothing works better for our son!
Will only sleep in his crib with his on!
Christina O.
I recommend Nested Bean to all of my new mama friends. My son sleeps really well in all three sizes he's grown out of and into.
Destiny R.
My little one loves it! He pretty much is sleeping thru the night.
Miranda W.
Our little one still has trouble sleeping. We’ve tried almost everything we know but they keep waking up multiple times nightly. We do feel the the zen sack has helped reduce the number of awake times though it’s still a nightly battle.
Resena H.
My little one likes her sleep sac, the only con is she gets warm throughout the night and then wants it off.
Christina T.
It's okay for the blanket but that's about it. My baby can't use the swaddler anymore b/c he's rolling over, so the reviews led me to buy this product. The bean pad doesn't make a difference for his sleep but at least he's warm! B/c he's so young, he still has the startle reflex really bad, so maybe when he's older this sleep sack may fulfill it's purpose
Michelle B.
Bought for my grandson his parents love it
Audrey B.
My two month old isn’t sleeping through the night but is definitely sleeping better with the sleep sac. Love it so much!
Ashley G.
Like all exhausted parents I was hoping for a miracle. I get some decent naps in but nights are still very hard with frequent wake ups. I think it’s good for what it is for sure but if you have a tough sleeper don’t put all your eggs in one basket.
Travis C.
Great sack. Really helps keep our son comfortable during his nightly snooze.
Linda L.
Helps grandson sleep during the night. Have used two sizes now as he grows!
Stefanie B.
I was amazed when I first out this on. Not sure what took me so long to try it but within 30 seconds she stopped crying and was out. I went online so fast and bought 3 more and a swaddle for nighttime!! Obsessed with how great these work! Pure magic!
Kimberly P.
Quality is nice. I love the double zipper to ease night time diaper changes. I’m not sure that it has helped my baby sleep better after a month. He still wakes 1-2 times at 4.5 months of age. Overall I don’t regret the purchase cause anything is worth a try and I wanted another sleep sack to rotate anyway.
Rashmi J.
We got the sleep swaddle and the sleep sack for our baby and she loved both! She sleeps comfortably for hours in both :)
Alexis D.
Loves his nested bean sack! I'm no longer spending hours with my hand on his chest and he's sleeping in longer stretches after only a few days
Heather S.
I bought this for my 2 month old who was waking every 2-3 hours during the night. When we use our nested bean he will typically only wake once around 3am. We've even had a couple nights where he has slept from around 10:30pm to about 7 am without waking!
Staci F.
It’s an ok sleep sack. I wouldn’t say it’s a miracle worker though. It didn’t really help my son sleep a lot better. Maybe a little though. But the biggest disappointment was I got the 0-6 months bc my son is only 14lbs and it says it’s for height up to 30 in but my son is 26 inches and it’s basically too small already. Also I wouldn’t say it’s for year round, it’s pretty thin. He feels cold when he wakes up and he has fleece footed pajamas on underneath.
Olga T.
This product is very soft and the two way zipper is useful. Nevertheless, I did not find it super effective for sleep improvement, as advertised. It is just a sleep sack, therefore considering the price, would not recommend purchasing one.
Vanessa K.
Nice

This sleeping zen sack haven’t helped my baby to sleep longer or better unfortunately. I've been using it for two weeks and there are no changes at all. The longest nap my daughter will take in the sleeping zen sack is 15 minutes not longer, also during the night she keeps waking up to 5 times. I'm happy with the material, is very nice and comfortable and keeps my baby worm, and I don't need to worry that she will cover herself during the night while she sleeps in her crib.

Selling sleep solutions to overtired desperate parents is almost too easy. I bought this sack for my 14 month old going through a 2 week (seemed forever) sleep upset. We had 2 second hand nested beans size M but he outgrew those. This L one seems to not to have the same effect (comparing a night with and without) He is sleep trained. However! Would recommend to use during sleep training. Other than that great quality cotton sack for everyday use. Can put it on and off in 10 seconds or less.

The best sleep sack for our little one.

My LO enjoys the nested bean quite a bit. I do wish the sleep sack was 2 inches longer. I feel like I have to keep yanking the fabric down so he has room to wiggle his feet. He is 11 weeks but I guess he is a little tall. Other brands are longer so I rotate with those as well. Also, I ordered 2 of these sleep sacks and one of them has the rediculously long tags sewn on the outside of the garment instead of on the inside.

My son LOVES this sleep sack! When transitioning him out of the swaddle, this is the only sleep sack he would actually sleep in. He’s now 6 months and we needed the bigger size. Such a great purchase!
Carly B.
Our daughter would sleep all night swaddled, but when she started to roll and we had to remove her arms from her swaddle, she was not happy and couldn’t seem to stay asleep. We purchased the nested bean sleep sack and she immediately began sleeping through the night again! She loves it!
Xorica P.
The sack has really helped my 2 month angel fall asleep calmly. Best investment I've ever made!

Hello! We have been HUGE fans of the sleep sack. Our daughter is literally obsessed and wears it almost 24/7. She is going to be a sack race champion. We have bought 6,7,8 maybe? We LOVE them but my rating is based on the change of the tag color. Our daughter noticed and is NOT a fan. It is now “new sack” because she can tell a difference regardless, can’t recommend nested beam enough!
Erin F.
This is a really well made product. I like the way it unzips, the fabric, its ability to reverse and the easy snaps, but it hasn't worked the magic for us that it seems to have for other parents. He's not sleeping through the night. He's not even really sleeping better. Really wish it had worked.
Lyndsey S.
My 4 month old loves it! He sleeps in it every night!
Jean R.
Bought as a gift and recipient loves it!

Definitely worth the money! We started using it on our 7 week old because he was wiggling out of all his velcro swaddles. Within the first 3 days, he went from waking up every 3 hours to sleeping for 7 hours straight! What a game changer! We have been using them for 3 weeks now, and he consistently sleeps for 7-7.5 hours, followed by another 2-4 hour stretch. We switched from arms-in swaddles to these arms-out swaddles on the first day without issue, but they also sent instructions on how to transition them if they need more time. So glad we tried these! I highly recommend these!
Carol W.
Its a good sleep sack. It took a little getting used to. Putting it on, I prefer the zip up in the front sleep sacks better honestly.
Sara C.
High quality product! My 4 month old daughter will sleep 7-9 hour stretches at night!!!
Shannon M.
Was thinner than I expected and ripped when I attempted to remove the very large tag from the sleep sack.
Melissa Z.
We absolutely love the Nested Bean sleep sack. Our daughter has been using these sleep sacks since we stopped swaddling her at 4 months old, and is now 7 months old and still sleeps great! The fabric is so soft and very comfortable against her body, and washes very well too. Highly recommend. We have 4 of them now, to always have a clean one on hand.
Ashley R.
Love love these sacks
Casey V.
My little one loves his sleep sack! He sleep great with it.
Krista P.
I love all of your products!! My 8 week old sleeps so good!!! I have tried at least 5 different swaddles and your brand is by far THE BEST!!
Haven H.
We are on night 5 of our zen sack and I absolutely love it! Wish I would have had these for my two older ones!
monique r.
My 2 month old has been sleeping all night within the second day of use.. he goes to sleep around 9:30-10 and awakes about 5:30-6. We have seen a tremendous difference
Priyanka P.
First night in his sleep bag and he’s sleeping through! I am loving it!!
Valerie H.
I absolutely love the nesting sacs! If I could have one for every single day I would! My baby gets soooo cozy in them and even my older baby loves them too. I’ve posted a ton of pics on my insta as well of my baby in there’s
Mrsdrix_realreviews
And I’ve mentioned to everyone THEY NEED ONE NOW
Rachel F.
I chose this sleep sack for my daughter when she transitioned out of her swaddle at 4 months. I chose it because of all the rave reviews I saw. It took 4 days for her to adjust to her arms being free. She sleeps better with this sleep sack than she did with the swaddle! We went from 6 hours of no wake sleeping to 9 hours of no wake sleeping. I will recommend this to any parent! Great purchase.
Ashley R.
Absolutely love these sleep sacks! I was given my first nesting bean sleep sack at my baby shower, as a first time mom I was terrified to swaddle my baby in a blanket… he wiggled so much! I was scared it would’ve come lose in his sleep and could’ve been a hazard.. but with the nesting bean sleep sack I can rest better knowing my baby is warm and cozy in a safe sack! Ive already bought another on my own and plan on getting one each time he grows out of one ❤️
Melissa M.
My daughter loves her sleep sack! Not only does she sleep longer, she now identifies her sack with sleeping time and starts self soothing as soon as we put her in it. Couldn't love this product more. Wish I had known about it when my older kids were babies.
Amanda D.
I got this for my granddaughter. Her Mom will not let her have a blanket for fear that she will strangle herself. So this is the perfect solution. My daughter loves it. My granddaughter will arrive in October.
patricia p.
Love it
Kasie B.
Our son would not sleep in his crib after the bassinet transition. Once we got these sleep sack he now sleeps all through the night with no issue. We love it!!
Melissa T.
My son loves this sleep sack. He's a NICU baby and is used to being swaddled so now that he's a bit older he's not needing as tight as a swaddle and the weight on his chest is perfect to help him fall asleep.
Danica Kristl D.
Helps my LO sleep longer. Will definitely purchase another one. I just wish that it is longer. My LO is kind of average height and on the light side and I feel like he’s already outgrowing the medium.
Julia S.
My son loves the sack and sleeps so well and through the night
Misti S.
My son has worn it 6 times and slept through the night once not sure if it's working for us.
Veronica T.
I started using the nested bean sack when my daughter was 3 months old.. it helped her sleep through the night! I decided to use a regular sleep sack when I noticed her sleep pattern was consistent as grew out of the bean. Then the 10 month regression hit.. I knew that I needed to buy it again in her size. It worked almost instantly! I can’t thank the Nested Bean enough for creating such magic! I can finally sleep again!!
Erin H.
This hasn’t worked that well for us. Haven’t seen much of a change with the sleep of our 3 mo. old.
Gabriela G.
I was super excited to try this product in hopes it would help my little one sleep better. There was no change in sleep. I tried having my little one wear it for bedtime and nap times. It is super soft and easy to put on and take off. He continues to use it for comfort but no change in sleep.
Courtney T.
I was honestly skeptical. There are so many products that promise results and don’t deliver, but this one is LEGIT! I had so much trouble putting my little one down to sleep, but now when it’s bedtime I literally feed him, change him, and put him in the bag. He does a little shuffle and falls right asleep! He also is able to soothe himself when he wakes up without me helping him, which is something I’ve never experienced with any of my kids! I can’t recommend this product enough!
Olivia W.
My daughter loves it!
Jacqueline O.
Great!
Melissa H.
My son is staying asleep longer.
Morgan S.
Hasn't made any difference to my child's sleep unfortunately
Is a good quality sleeping bag though. But cost me a lot to ship overseas.
Will keep trying to see if it makes any difference
Rachel S.
Love this one because it has weighted beads spread out all over the chest piece instead of just the center circle in the previous size(6_12 months)...it works better for my LO since she's a tummy sleeper.
Gisselle G.
I love the zack since I bought this my daughter sleep straight between 6-7 hours so happy about it.
Thank
Lynelle M.
I need another will order soon
Samuel H.
We've had it for about a month now, we use it every night for our 11 month old, she was waking up about 3 to 4 times a night maybe less, the past couple of weeks, she'll wake up 1 or 2 times a night now, so I guess it's working some what.
Ilse M.
When we first bought it we thought it would be your “average” sleeping sack but he slept through the night the first day we got it!! I haven’t slept a full 7+ hours since he was born (he’s almost 10 months) and now I get to have my sleep back!! I trust Nested Bean with my SLEEP lol I’m always recommending it to my mommy friends as well.

We had the smaller size but as my daughter got bigger we have to get the bigger size. We love it!! And she seems to love it also. The customer service is AMAZING!
Alondra B.
Love this sleep sack! Best thing to happen to us as first time parents little one sleeps so comfy and helps prevent her getting stuck in between crib bars!
Trinh N.
It didn’t work for our 5 months baby. She still wake up every 3 hours for feeding. I was really hoping it would help because we had tried so many different brand.
Dean D.
Weighted sleep sack doesn't seem to help my baby get to sleep any quicker or stay asleep any longer. In hindsight, I wish I would've bought twice as many normal sleep sacks to have more in rotation while others are being washed. Hopefully this helps other babies, but I don't feel the added cost was worth it for mine.
Nadia P.
Nothing works better for our son!
Will only sleep in his crib with his on!
Christina O.
I recommend Nested Bean to all of my new mama friends. My son sleeps really well in all three sizes he's grown out of and into.
Destiny R.
My little one loves it! He pretty much is sleeping thru the night.
Miranda W.
Our little one still has trouble sleeping. We’ve tried almost everything we know but they keep waking up multiple times nightly. We do feel the the zen sack has helped reduce the number of awake times though it’s still a nightly battle.
Resena H.
My little one likes her sleep sac, the only con is she gets warm throughout the night and then wants it off.
Christina T.
It's okay for the blanket but that's about it. My baby can't use the swaddler anymore b/c he's rolling over, so the reviews led me to buy this product. The bean pad doesn't make a difference for his sleep but at least he's warm! B/c he's so young, he still has the startle reflex really bad, so maybe when he's older this sleep sack may fulfill it's purpose
Michelle B.
Bought for my grandson his parents love it
Audrey B.
My two month old isn’t sleeping through the night but is definitely sleeping better with the sleep sac. Love it so much!
Ashley G.
Like all exhausted parents I was hoping for a miracle. I get some decent naps in but nights are still very hard with frequent wake ups. I think it’s good for what it is for sure but if you have a tough sleeper don’t put all your eggs in one basket.
Travis C.
Great sack. Really helps keep our son comfortable during his nightly snooze.
Linda L.
Helps grandson sleep during the night. Have used two sizes now as he grows!
Stefanie B.
I was amazed when I first out this on. Not sure what took me so long to try it but within 30 seconds she stopped crying and was out. I went online so fast and bought 3 more and a swaddle for nighttime!! Obsessed with how great these work! Pure magic!
Kimberly P.
Quality is nice. I love the double zipper to ease night time diaper changes. I’m not sure that it has helped my baby sleep better after a month. He still wakes 1-2 times at 4.5 months of age. Overall I don’t regret the purchase cause anything is worth a try and I wanted another sleep sack to rotate anyway.
Rashmi J.
We got the sleep swaddle and the sleep sack for our baby and she loved both! She sleeps comfortably for hours in both :)
Alexis D.
Loves his nested bean sack! I'm no longer spending hours with my hand on his chest and he's sleeping in longer stretches after only a few days
Heather S.
I bought this for my 2 month old who was waking every 2-3 hours during the night. When we use our nested bean he will typically only wake once around 3am. We've even had a couple nights where he has slept from around 10:30pm to about 7 am without waking!
Staci F.
It’s an ok sleep sack. I wouldn’t say it’s a miracle worker though. It didn’t really help my son sleep a lot better. Maybe a little though. But the biggest disappointment was I got the 0-6 months bc my son is only 14lbs and it says it’s for height up to 30 in but my son is 26 inches and it’s basically too small already. Also I wouldn’t say it’s for year round, it’s pretty thin. He feels cold when he wakes up and he has fleece footed pajamas on underneath.
Olga T.
This product is very soft and the two way zipper is useful. Nevertheless, I did not find it super effective for sleep improvement, as advertised. It is just a sleep sack, therefore considering the price, would not recommend purchasing one.
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.
