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
Kristy L.
Love it like everything else I’ve gotten from them!

Laura T.
She has been sleeping through the night!
Kati L.
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.

Great product. Speedy delivery.

Great for summer sleeping.
Mac K.
Great !
Kelly A.
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.
Jessica M.
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
Tini I.

Cheryl S.

Julianna S.
Andi C.
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!
Maki B.

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.

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!

Awesome well made product!!!

My Granddaughter loves her sack!! Thank you nested bean!! Well worth the money!!

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

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!

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!!!

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

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
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!
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.
