I wish I could say this made a difference for sleep but it hasn’t. It is a lovely material but just a regular sleep sack for us, didn’t help with baby waking a lot through the night.
Michael F.
My son has acid reflux and he is so hard to get to calm down and go to sleep. Exhausted and desperate to find something to give us some sort of a break we come across your weighted zen sacks; the very first time we put him in it for a nap he fell asleep without much of a fight at all. I think it’s definitely a very good product to have!
Tina G.
My baby is a side sleeper. I switch putting the weighted part in the front and back and baby seems to like both. Highly recommended.
Rosmari L.
I love it! I used it on my first child and she slept so great that I bought it again for my second child.
Heather F.
Love it
Charidie T.
Overall a great sleep sack. It’s easy to wash and the fabric is soft and cool for hot summer nights. My only wish is that the shoulder straps were thinner because the have a tendency to fold in half due to chunky baby neck and cheeks. Also I don’t believe that it will still fit her at 6 months. For reference, my daughter is 3.5 months, 14-15 lbs, and 27.5 inches long.

Material gets caught in babies legs because too thin and sheet like
Teri U.
We were really worried transitioning our baby girl from a full body swaddle to the arms free nested bean, because she slept so well swaddled up. As we approached the 3 month mark it was time to free her arms. The arms free nested bean works very well. To our surprise, our baby girl sleeps equally as well in the nested bean. I credit this to the weighted top in the design. We are very happy with this product and plan to buy more as she grows.
Kim C.
Fast Shipping, lightweight for new baby
Rosa M.
The day I got it my baby started sleeping more hours than usual. The bean area isn’t as heavy as I was afraid it was going to be, it was just the perfect amount. I would recommend this to anyone.
Amiee S.
I love these sleep sacks because our baby does! We’ve been using these since we transitioned from swaddling and our little girl has been the best sleeper! A dream come true for parents…we wouldn’t try anything different and are not sure what we’ll do when she grows out of the last sleep sack (15-24 months). Worth every penny, great quality!
Amber M.
My 4 month old loves his sleep sack! He sleeps so good with it. I bought this as a final thing to try because he absolutely would NOT sleep. First night using it and he loves it. He’s a tummy sleeper so he wears it backwards and as soon as we put it on him he instantly calms and puts himself to sleep. 10/10 would recommend !!
Mariam H.
Same as other
Megan U.
The material is so soft and I love that it's a tank top fit on top. It's great for the super hot weather. I havent noticed better sleep from our little one and it's been about a week but hopefully it's coming soon!
Katie H.
I really like it, it's nice to have him covered with something he can't kick into his face or off. The weight seems to help keep him down but as of sleeping longer I have not seen the results of that yet. The weight on the sleep sac seems to be a little higher then on the onesies. I purchased them as well and really like the onesies so far. Same results with the sleep, however. It's easier to put him down without waking up when putting him into his bassinette (which was a real BIG struggle for us) but the staying asleep he is still up every 1 -2 hours, but time will tell.
Nadine F.
Love this organic cotton sleep sack. Lightweight fabric and perfect for the summer season. The weighted bean no the chest gives just the right amount of comfort for your baby to sleep soundly. Highly recommended!
Heather C.
She loves it
Elizabeth P.
Make sure to wash it before using. It gave my baby a rash all over her stomach. But once I washed it, it was great! It is a bit difficult to put it on her because she is always rolling around, so the snaps are hard to snap on. But other than that, we have loved it! She has slept really well.
Samantha D.
So far we have had this product for one week. I haven’t really seen the results, but will continue tkk on try.
Taylor C.
Sleeping through the night at 2.5 months!!! Love the feel and lightweight material!
Maki B.
LOVE this sleep sac! So incredibly soft and cozy - even my toddler tried it on and ran around in it, haha!
Kelly P.
Really beautiful material, very well made. Love the shape and the concept of the weighted chick on the chest, but we gave this a very fair try and it was just not what our 6month old needed. I’m sure it works spectacularly on other babies and is certainly worth a try in my opinion, especially for very desperate parents. Just be ready for it to *not* be the answer, just in case
Dominique F.
Just didn’t notice any difference. Except she can’t get up and go on her own

Before I got the nested bean sack my baby would wake up every time I put him in his own crib. He would be fast asleep but as soon as I laid him down in his eyes would pop right open. I decided to buy the nested being sleep sack After I did extensive research regarding all of the options.
I am so happy that I purchased the sack. I’m able to sleep with my husband by ourselves to get the quality time we need. My baby loves it and looks forward to sleeping in each night. Thank you nested bean sack you are the best!
Buy this sack! You won’t be disappointed
Ana C.
Baby stays asleep longer. Will wake up but feel the weight and fall back asleep. Definitely recommend
Kayla H.
We consistently put our baby in the Zen Sack at night to sleep & she now sleeps 8-10 hours every night. We started her in it at 2 months & she’s now almost 3 months. Best sleep sack out there!!!
Cortney S.
I absolutely love this. He sleeps so well. He wakes up once and goes right back to sleep. He’s 5 months. I highly recommend this product, and have already recommended it to my mommy friends!!!
Hayleah H.
We love this option for a lighter material since we live in Texas. Our LO sleeps so well in these.
Jennifer H.
Really soft, beautiful quality. Don’t think I see a change in her sleep. But we are also in the 4month sleep regression timeframe.

I love this premier bamboo fabric for summer. We live in California and it’s warm, but I still like having a sack on her, so this is perfect. The medium size fits my 6 month old great.
I just wish it came in plain colors like the original weight does.
Christopher O.
We bought this for my daughter in lieu of a transition sack around the 7 week mark and my daughter loved it. The weight was heavy enough to prevent her startle reflex from waking her up, but it’s not heavy enough to hurt her. She’s been sleeping 5-7 hours for about 2 weeks now.
Victor F.
Great product. Helps my baby to get a better sleep, definitely a game changer.
Jennie E.
The sleep sack is cute and well made. I ordered bec I'm desperate for some sleep. After reading a bunch of reviews I finally caved. Maybe my baby is defective, bec she still doesn't sleep. Lol. So no magic beans for us and I'm still one very tired Mama.
So now she has a nice $50 dollar blanket.
Kristy O.
My DIL says my grandson has slept great in this Zen Sak Premier (bamboo material) for last couple nights! He loves it!! Will be ordering more for sure!! Has the cotton ones as well but loves the bamboo ones even more!!
Lorena S.
Such a comfy and cute sleeping sack. Very soft and very easy to put on. The weighted part is so nice to be able to use both on baby’s chest and even back. Always been a huge fan of this brand!!
Huda G.
Daughter is 4months old and wakes every two hours. I purchased the Nest sack and still see no difference after a week. I’m hoping that will change down the road but for now, this is my review. Every baby is different, mine is not favoring this yet. The quality is great though.
Julia F.
Soft, lightweight and perfect for warmer climate. Baby loves the extra weight on chest too.
Ashley W.
I absolutely love these! My sons sleep DRAMATICALLY improved while wearing these sleep sacks! I wish I got them sooner!!!!
Karissa T.
My little guy loves his ! Puts him to sleep so fast ❤️
Anthony P.
Honestly, it came with a hole and my husband wrote in and was told to return it. We SHOULDNT have to do extra work because we received a defective product. Disappointed in that level of customer service.
Amanda I.
Recently switched to the Zen sack because we outgrew the Zen One. We have been using the nested bean products since 2 months old. They help my like guy sleep more restful. Plus, he looks so cute.
Ebony F.
Thought this product would be an answer to my prayers for my baby to sleep through the night. I would say I like the concept and the diaper changing zipper.

Changed my daughter's sleep in 4 nights! She loves feeling snuggled by the weighted bean on the chest.
Amy B.
My little one loves the nested bean zen sacks! We recently got the "premier" one for the upcoming hot summertime and so far it has been perfect and lightweight.
Patricia L.
My LO loves his sleep sack and gets excited about putting it on . Once he’s down he feels relaxed and sleeps throughout the night.
Celeste M.
My LO was used to being swaddled since birth. She disliked her hands being put inside the swaddle. We got to a point where we could no longer swaddle because she was really tall and her legs couldn't be wrapped. I read many reviews about the NESTED BEAN and decided I would give it a try. I am so glad I did, it really works. My LO sleeps very well through the night and her hands don't have to be put inside a swaddle.
Jenna I.
The butterfly design is beautiful and I love how light the bamboo material is. My baby loves it as well!
Lisa K.
Favorite light weight sack!! Love to use this one on warmer nights.
Lindsey W.
This is great cause he can't kick it off! With the double zipper changing at night is much easier. I love and hate he can move his arms around.
Meagan B.
This is great! I like that the fabric is thinner that the original, we live in Phoenix so this will be great for our many hot nights.
Kimberly P.
I love this sack ! Helps keep my little one asleep all night
Maria K.
I definitely saw a difference in her sleeping! Highly recommend:) she is 7 months old.
Cassandra C.
We love our nested bean! My 3 month old has been sleeping through the night since 8 weeks old❤️
Lauren.miller M.
The nested bean zen sleep sack has been great with helping our 3month old stay asleep longer. He settles when placed in his bassinet and then shortly falls asleep on his own.
Danielle M.
We like the softness and warmth of this sack and use it over a cotton sleeper. The zipper snags often in 3 places so that’s frustrating but it hasn’t broken so… we will keep loving it
Sandy S.
Tje fabric is lightweight and cool perfect for our warm climate. I love the design, its so cute.
Chelsea G.
The sleep sack has greatly improved our nights! My son is now sleeping 3-4 hour stretches and is getting good deep sleep. We chose the armless sack and it is perfect for him!
Jessica K.
This sleep sack is perfect for our son! It’s lightweight and breathable but still keeps him warm and comfortable. The print is so cute and the light weight helps him sleep throughout the night!
Kelly K.
Try it and you won’t regret it! I know all babies are different but the Nested Bean swaddle and sacks truly have been game changers for us. Our son is 8 weeks old and has used both the swaddle and now the sack. He is a very active baby and is one of the 1% who truly did NOT like to be swaddled. My friend let us borrow her NestedBean swaddle and he did the best with that one out of the many we tried. On a whim I decided to see how he would do in a sack because he was constantly trying to break loose and figured I’d try another NB product since he took so well to the swaddle. Well here he is at 6 weeks living his best free armed life in his NB sleep sack. He is sleeping 7 hours a night (also thank you Moms on Call) and I really think the support he gets from the gentle weight is helping him. Because he is such an active sleeper I think I am going to order the weighted footies as well!
I do want to say to those sleep deprived parents. I don’t think any product is a magic solution but this along with a good sleep routine I think goes a long way.
The fact that these are reasonably priced and they offer a return policy, you really can’t go wrong and recommend them to all my new mom friends !
Nanette M.
Super soft for baby's skin. Nap time lasts at least 50% longer, sometimes doubles. It's a nice extra layer for cooler days or nights without worring that he is too cold. The 2 way zippers are great, as well as being reversible for tummy sleepers. Definitely recommended!
Christina P.
Love the sleep sack. Definitely helps my lo sleep better.
Maria H.
The Zen Sack is amazing. Our little girl is 6 weeks old and was waking every 2 hours. Now, she’s sleeping 4 hour stretches, and I’m having to wake her up to nurse! It’s been so helpful!
Lauren K.
The first night with our son wearing this nested bean he slept in his bassinet and has ever since ! A life saver
Amanda M.
Night 1 of sleep sack, our 6 week old slept for 4 hours straight! She was waking up every hour on the hour previously. Magic!
Jayme F.
Love this sleep sack!
Paige J.
Cruz loves his sleep sack! He would wake up everytime I put him down, with the sleep sac he goes to sleep with no problems!
Nancy M.
I ordered a medium sleep sack for my 7 month old son. He wears 12-18 month clothes so I had a feeling this may be too small and I was right. The sleep sack fits him snuggly and I like to dress him to be comfortable at night with loose clothes. I will have to use a large on him and wish I could exchange the medium for a large. I do not think this is possible because I washed it before having my son come in contact with it as I do with all new products.
Other than that I think the design and concept is great.
Hope F.
Really didn't seem to make any difference in our baby's sleep.
Emily B.
Our baby likes the fit of this sleep sack the most as there is no zipper at her neck line. Very soft material. She was a good night sleeper before this sleep sack so I can’t say that at 2 months and sleeping 9 hours a night is all due to this sleep sack. I think she is very comfortable in this sleep sack and we will buy another in the future!
Kelly D.
Awesome well made product!!!
Martina C.
My Granddaughter loves her sack!! Thank you nested bean!! Well worth the money!!
Vanessa A.
So my baby will be 4 months tomorrow. I got it for him about 2 weeks or more ago. I got bamboo because he gets hot VERY easily and a lot. I really like the material for him. But to be honest I expected more but I don’t know why I did. It seems to be the same as the muslin sleep sacks I have for him. It hasn’t changed or done anything. My son doesn’t sleep longer and still won’t sleep in his crib. I guess you get lucky or you don’t. We didn’t.
Alexis R.
She loves it. Helps her stay asleep longer and helps her fall back asleep if she’s startled. Will be ordering more for backups
Abby A.
After almost 4 months of sleeping 2-3 hour long stretches, today we finally slept 8 hours. I totally recommend this product to every new parent like us!
ROSALINN B.
My son was hit hard with the 4 month regression at 3 months. He was up every 30min to 1 hour at night. 5 weeks into the regression I ordered this product. I kid you not he has been asleep for 7 HOURS!!! The first night with this sleep sack waking once for food and falling asleep instantly. I cannot recommend this product enough to everyone. The fabric is soft, the shoulder clips are strong enough to hold my wiggly little man, they are cute patterns and colours. So if you like sleep and quality products for a decent price this is the product for you!!!
Andrea T.
Although I did think the bottom half would be a little thicker, my baby’s sleep has improved immensely! He used to fight naps, now he is able to peacefully fall asleep on his own, and fall back asleep if he wakes before he’s ready.
Elisa B.
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

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.

Maria K.

We love our nested bean! My 3 month old has been sleeping through the night since 8 weeks old❤️

The nested bean zen sleep sack has been great with helping our 3month old stay asleep longer. He settles when placed in his bassinet and then shortly falls asleep on his own.
Danielle M.
We like the softness and warmth of this sack and use it over a cotton sleeper. The zipper snags often in 3 places so that’s frustrating but it hasn’t broken so… we will keep loving it
Sandy S.
Tje fabric is lightweight and cool perfect for our warm climate. I love the design, its so cute.
Chelsea G.
The sleep sack has greatly improved our nights! My son is now sleeping 3-4 hour stretches and is getting good deep sleep. We chose the armless sack and it is perfect for him!
Jessica K.
This sleep sack is perfect for our son! It’s lightweight and breathable but still keeps him warm and comfortable. The print is so cute and the light weight helps him sleep throughout the night!

Try it and you won’t regret it! I know all babies are different but the Nested Bean swaddle and sacks truly have been game changers for us. Our son is 8 weeks old and has used both the swaddle and now the sack. He is a very active baby and is one of the 1% who truly did NOT like to be swaddled. My friend let us borrow her NestedBean swaddle and he did the best with that one out of the many we tried. On a whim I decided to see how he would do in a sack because he was constantly trying to break loose and figured I’d try another NB product since he took so well to the swaddle. Well here he is at 6 weeks living his best free armed life in his NB sleep sack. He is sleeping 7 hours a night (also thank you Moms on Call) and I really think the support he gets from the gentle weight is helping him. Because he is such an active sleeper I think I am going to order the weighted footies as well!
I do want to say to those sleep deprived parents. I don’t think any product is a magic solution but this along with a good sleep routine I think goes a long way.
The fact that these are reasonably priced and they offer a return policy, you really can’t go wrong and recommend them to all my new mom friends !

Super soft for baby's skin. Nap time lasts at least 50% longer, sometimes doubles. It's a nice extra layer for cooler days or nights without worring that he is too cold. The 2 way zippers are great, as well as being reversible for tummy sleepers. Definitely recommended!
Christina P.
Love the sleep sack. Definitely helps my lo sleep better.
Maria H.
The Zen Sack is amazing. Our little girl is 6 weeks old and was waking every 2 hours. Now, she’s sleeping 4 hour stretches, and I’m having to wake her up to nurse! It’s been so helpful!
Lauren K.
The first night with our son wearing this nested bean he slept in his bassinet and has ever since ! A life saver
Amanda M.
Night 1 of sleep sack, our 6 week old slept for 4 hours straight! She was waking up every hour on the hour previously. Magic!
Jayme F.
Love this sleep sack!
Paige J.
Cruz loves his sleep sack! He would wake up everytime I put him down, with the sleep sac he goes to sleep with no problems!
Nancy M.
I ordered a medium sleep sack for my 7 month old son. He wears 12-18 month clothes so I had a feeling this may be too small and I was right. The sleep sack fits him snuggly and I like to dress him to be comfortable at night with loose clothes. I will have to use a large on him and wish I could exchange the medium for a large. I do not think this is possible because I washed it before having my son come in contact with it as I do with all new products.
Other than that I think the design and concept is great.
Hope F.
Really didn't seem to make any difference in our baby's sleep.
Emily B.
Our baby likes the fit of this sleep sack the most as there is no zipper at her neck line. Very soft material. She was a good night sleeper before this sleep sack so I can’t say that at 2 months and sleeping 9 hours a night is all due to this sleep sack. I think she is very comfortable in this sleep sack and we will buy another in the future!
Kelly D.
Awesome well made product!!!
Martina C.
My Granddaughter loves her sack!! Thank you nested bean!! Well worth the money!!
Vanessa A.
So my baby will be 4 months tomorrow. I got it for him about 2 weeks or more ago. I got bamboo because he gets hot VERY easily and a lot. I really like the material for him. But to be honest I expected more but I don’t know why I did. It seems to be the same as the muslin sleep sacks I have for him. It hasn’t changed or done anything. My son doesn’t sleep longer and still won’t sleep in his crib. I guess you get lucky or you don’t. We didn’t.
Alexis R.
She loves it. Helps her stay asleep longer and helps her fall back asleep if she’s startled. Will be ordering more for backups
Abby A.
After almost 4 months of sleeping 2-3 hour long stretches, today we finally slept 8 hours. I totally recommend this product to every new parent like us!
ROSALINN B.
My son was hit hard with the 4 month regression at 3 months. He was up every 30min to 1 hour at night. 5 weeks into the regression I ordered this product. I kid you not he has been asleep for 7 HOURS!!! The first night with this sleep sack waking once for food and falling asleep instantly. I cannot recommend this product enough to everyone. The fabric is soft, the shoulder clips are strong enough to hold my wiggly little man, they are cute patterns and colours. So if you like sleep and quality products for a decent price this is the product for you!!!
Andrea T.
Although I did think the bottom half would be a little thicker, my baby’s sleep has improved immensely! He used to fight naps, now he is able to peacefully fall asleep on his own, and fall back asleep if he wakes before he’s ready.
Elisa B.
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

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!

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
