I bought this for my grandson and he loves it. He is a newborn. He instantly calms then falls asleep with it in. Very durable and worth the price. The best feature is the bottom zipper so his legs can be exposed if needed as he grows. Easy on and easy off! I can’t say enough about it. A must for kiddos!
Dinora A.
We love our Zen Sack Classic in our favorite color lilac. Baby fell asleep right away for 8 hours the first night.
We like the adjustable shoulder straps
as she grows, she likes the freedom to kick her legs and the light weight on the chest, soothes her to sleep. We love it so much, we purchased another one in pink! Highly recommend it♡
Caressa G.
We love it!
Stephanie R.
We love Nested Bean. Our 8 week old has hated being swaddled from the very beginning and did ok in the hospital sleep sacks. However, she’s a growing girl and those did not last long. These are plenty big for her and the slight weight on the chest helps calm a sleet baby that only wants to be held! We get 3-4 hour stretches most nights using this sleep sack. If you’re on the fence, jump over and join us!
Ashley C.
Best sleep sack ever! I’d recommend to anyone.
Ashley S.
As it states, it takes a few days to really help with sleep but it definitely does what it says it does.
Celeste O.
My son never sleeps without his sleep sack! So soft and the perfect weight, for the feeling of a gentle touch and the perfect nights sleep.
Wendy G.
Our baby girl loves it!!
Ashley G.
Love the nested bean sack! Our little one sleeps so soundly thanks to his nested bean sack!
Iris Y.
This sleep sack helps our 2 month old sleep like a champ! We got our first one from my sister and then went on to buy two more! Couldn’t be happier with our purchase!
Lazara N.
I loveeeeee it!!! It’s so comfortable!! My baby sleep all night with this
Dinora A.
I absolutely love it! My daughter stays asleep and does so comfortably. I will buy again and again. Excellent product and I highly recommend it
Katie S.
The material is so soft and lightweight. It’s easy to put on and take off. The color is nice too, very neutral. As far as sleeping goes, I’m not sure if I have noticed a difference. My son has been a pretty lousy sleeper since the start. I was hoping this would help as he is now 8 months old
and still doesn’t sleep through the night. However, he might be going through a regression or teething at this point.
Lindsey E.
Got a pair of these for my 14 month old twins. They’ve always been good sleepers, but my son is super wiggly and had been escaping from his Halo and Burt’s Bees sacks. He does figure out how to wiggle out of the Nested Beans too, sometimes, but I think that’s because I put him in a 15-24 month size and he’s a bit below the weight limit. He does seem to have figured out the snap mechanism on the shoulder though, so we’ll see how it goes. These appear to be well made and great quality, they are soft and comfy and breathe well, and it seems like they will last a long time. The weighted chest is nice, we wear ours backwards for both babies as they are wiggly tummy sleepers. I can’t say they sleep much better as they are already good sleepers, but I’m glad we got these.
Marisa C.
Our little one just started to roll in his crib at night so we had to say goodbye to our beloved swaddles and find a new solution to keep him sleeping through the night. We bought the Zen Sack 2-pack and after the first night he was sleeping 9+ hours through the night!! We’ve noticed he puts up less of a fight when going down for naps and bedtime when we use his new sleepsack. We love ours and definitely recommend these to any parents with wiggly littles for a great nights sleep.
Jaimee R.
These are the best sleep sacks I’ve ever used. Solid company with excellent customer service as well!
Megan H.
We love our Nested Bean! The end!
Taylor W.
Love!
Lauren P.
We love our nested bean sleep sack. This crazy little man is 3.5 months old and kicks all night. Resulting in no blanket left on. So I tried the nested bean. It’s like magic. It moves with him, comfortable material, and breathable. It works perfect at night for our little man while he is hospitalized too the double zipper allows mom to run his tubing out the bottom and use the button to secure the tubes. I would recommend it to any new mother.
Eve K.
Love this sleepsack! 6 month old Baby sleeps 11-12 hours straight in this. Soft and comfy.
Lindsey E.
Got these for my 14m old twins as they were wiggling out of their Burt's Bees and Halos. I love the concealed zipper and adjustable snaps, my boy still got one arm out but hasn't Houdini-ed himself out of it yet. The fabric is super soft and we wear the weighted part backwards. We got these sacks just as we transitioned to 1 nap, so I can't say for certain that they have helped with their sleep, but they are currently sleeping well for nights and naps.
Brynne V.
Beautiful color! We swear by these and have used them since she was a baby!
Suzan B.
This sleep sack is amazing.
Purchased for my granddaughter.
She actually SLEEPS!!!
Claudia A.
My son hates to be swaddled, he literally grunts and grunts until he is unswaddled. I had a nested bean from my daughter size 6-12 months too big on him still. So bought the 0-6 months and it’s perfect with tons of room to grow. He’s 6 weeks now and he’s sleeping so much better now. 4-5 hour long stretches and very little grunting now. This is a must have!
Kim K.
Love this sleep sack and so does my little Vinny! He is instantly calm in this and it is light enough fabric for sleeping in the warmer house during summer. I also love how its adjustable and has a zipper opening. I would definitely recommend to anyone with a little one.
Marlene M.
The lavender color sleep sack came punctured right in the middle & with a busy life I haven’t had time to call customer service but other than that it works for the purpose l.
Kim M.
The material is very soft and comfortable. The design is made to make it very easy to get a sleeping baby in and out of with out jostling them too much. I have been happy with it and baby seems to sleep very well with it as well. Baby hasn’t not gotten too hot but seems to stay at a comfortable temperature.
Allison D.
So cute! And my son loves it he sleeps so good now!
Taylor Y.
My baby loves this sleep sack!
Michelle W.
Made sleeping so much better and she falls asleep on her own!!
Tarah S.
My son sleeps so great in this. The tag is soothing too; he likes to grab it and hold it!
Ana E.
Soft and good quality fabric!
Has zippers on the side and it’s easy to put on baby.
Natasha K.
We got one and it seemed to work well. Bought another as a backup. Lately doesn't seem to help our LO self-soothe...maybe he's used to it or maybe it's something else! But either way, it's a good-quality sleep sack.
Janelle M.
My daughter sleeps all through the night at 3 months old. She loves this!!! So do I!
Martha K.
Works like a charm - restlessness stopped immediately after my baby started wearing the weighted sleep sack.
scarlett C.
It’s decently soft but the shoulder straps don’t lay flat after washing so when baby turns her head it knocks the paci out of her mouth and rubs her face.
Armanda C.
My daughter likes contact sleep and this sleep sack provides that. I like that the beans inside aren’t stiff but are comfortable to her when she sleeps. I love that the material doesn’t make her sweat but comfortable during the night. Plus she looks super cute in it when she wakes up☺️
Hannah R.
Noticed an immediate improvement. Went from waking up twice a night to only once. And when he would start to wake he was able to settle back down and not really wake up fully. We like this product and the print is adorable!
Mary K.
Baby loves these sleep sacks. He likes to play with the tag that’s on the outside? Not quite sure why there are giant tags on the exterior of the sack, but he is definitely sleeping soundly!
Alanis P.
My baby girl loves it!
Samantha G.
Worth every cent. My baby girl would only sleep for about 45 mins to an hour until the weighted sleep sacks. The first night she tried it she slept for 4 hours and I felt like a new person lol. They keep her settled and are light enough for summer but warm enough for cooler months with a light pair of pajamas underneath.
Samantha G.
Amazing purchase! I bought the Zen footie pajama and it worked so well I had to buy this sleep sack and the size up so my baby girl would have it when she needed to switch. It’s perfect.
Kim W.
This works great! Sleep training my baby, and she would scream for hours after being put down. Using the Nested Bean, she cried 45 min the first night, 30 min the second night, and went right to sleep the third night. It's been a dream.
Gina K.
The material felt like great quality, but unfortunately our little guy kept getting his legs caught in the sack which woke him up.
Lisa
This is our first time trying a sleep sack. My baby is 4 months old so I wasn’t sure if we were too late in the game, but it has been great so far.
My daughter has a habit of tossing and turning throughout the night which doesn’t lead to good sleep. But with this sleep sack on she tosses and turns significantly less. She will go at least 3-4 hours straight without waking up. She will start tossing and turning when she is about to wake up to nurse.
I say get it! I wish I would have gotten one when she was a newborn and started her in the sleep swaddle. If you buy the swaddle one, not that the arms unzip so it can also be worn as a sack. Which is really convenient to transition. I tried the swaddle and she doesn’t like being constrained at this point. But we use it as an extra with the arms unzipped.
I also purchased the footies for when she is a little older so she has that to transition to next.
Carmen P.
I love the sleep sacks but my god the shipping to Canada is atrocious. Took over a week for it to even be shipped. Been 3 weeks since I ordered and still hasn't arrived
sonja s.
It is a great sleep sack but it smelled really bad when I opened it. I washed it and it actually made the entire load of laundry smell so I had to re wash everything
Bobbie A.
I have used nested bean sleep sacks and onesies for all 3 of my kids. Love the quality of them and my kids love them too.
Meagan C.
This has transformed my 2 month old regular sleep from 5 hours to 7 hours ! Love the rest he’s getting !
Eyleen V.
My baby would not nap more than 20-30 minutes per nap during the day, ever since we got this weighted sleep sack she sleeps over an hour. So thankful for this! Its perfect. 10/10 recommend
Laura I.
I love these sleep sacks and the purple one is beautiful! Super soft and cozy and my little one seems to like it too. Best part is no velcro to wake them up!
Kayla C.
Love it! Game changer for getting 12 months old to sleep on her own at night!!
Shivani V.
Baby looks a little uncomfortable in this
Andrew M.
We love our nested bean sleep sack! Helps our baby sleep though the night.
Irina G.
I honestly can’t believe it works as well as it does!
I NEVER write reviews. Usually it really isn’t worth my time but here I am…
My son started flipping over on his stomach and we had some hard nights trying to get him used to sleeping while not being swaddled. Once the sleep sack came in I was really hoping it would work. He’s 3 1/2 months old and the first night he slept through the night! I thought maybe it was a coincidence.The next week he would either wake up once at night or sleep through the night.
The only thing I wish they had was maybe a sleep sack that had the weight on both the tummy and back. Or something like that because I don’t always know if he’ll fall asleep on his belly or back at night.
Overall a great product!
Mwai C.
I bought Nested Bean sleep sack for my baby’s naps in the daycare. I got 6-15 months size for my 5 month old very tall baby. The material was thick but very comfortable and not hot.
Allison W.
He might sleep on his side/back at times but these zen sacks have been a life saver!
Mannin P.
Got it for my 9 month old and she’s sleeps great in it!
Maryhelen R.
We transitioned our 2 month old into this Nested Bean Sleep Sack and he began to sleep a continuous 8-10 hours a night! The first night he woke up after 5 hours but with a simple rock and forth, he went back to bed and stayed asleep for another 3 hours. On the second night he stayed asleep and he’s been sleeping through the night ever since. We’ve been using this Sleep Sack for about 2 weeks now and it has been so great!
Natasha K.
The sleep sack seems to be working well! There are still nights when he's up a lot with teething, but when our sleep sack needed to be washed and he had to go a couple of nights without it, he woke up a lot more often. Now he actually puts himself back to sleep if he wakes up at night! We just bought a second so we don't have to worry about one being in the wash at bedtime...
Erika A.
Our baby boy loves the nested bean sack. He transitioned to this one after the swaddle. Washes great and is very soft.
Fife K.
These sacks are so easy to use and big. My son loves them.
Ashton Caroline A.
Excellent customer service! 10/10! The Zen Sack tore at the seams after a short period of time, and with a few pictures, I was able to get a new one at my house in a few days. It made me feel great to invest in nicer sleep sacks when the company backs up their products like that! This was a fluke as we have had several others that withstood lots of use!
Krista M.
We have seen a significant difference when our baby sleeps in his nester bean. He is much more relaxed and calm.
Maggie D.
She loves her sleep sack and it calms her down quickly.
Miranda S.
Thought the little weighted part would be a little heavier. It so far hasn’t done anything for my daughter. I wish it had worked out for her!
Becky H.
The first night in the sleep sack was rough. Baby girl kept waking herself up. Since then she is responding well and loving the sleep sack, she started sleeping with her arms up and has been sleeping later too.
Emily L.
I love nested bean sleep sack. It was recommended by my daycare teacher because they other parents used it and found the difference. These are much better to calm down my little one who was terrible at sleeping. The weight actually helped to put him to bed because that’s what I did with my hands on his little chest before I started using nested bean. I purchased 4 already and I will definitely purchase more until my baby is transitioning to blankets
Eileen V.
We love Nested Bean! We started with the Zen One sack to transition out of swaddling and now she’s 7 months old and in her big girl sleep sack and LOVES IT! Rolls on her tummy to sleep and loves it.
Kaitlyn P.
The pattern is amazing and the quality is great! Does it help our little one sleep better, I can't really tell. It's definitely not the miracle we were hoping for, but it's not hurting anything.
Faasefuout S.
Best purchase I’ve made for my needy baby! I only wish I bought this sooner (like one baby ago) because my first child also could have benefited from this. Was hesitant that it would even work for us but soooo glad it does!
Jessica W.
Our baby girl loves the nested bean sleep sack! She immediately went to bed easier and stayed asleep longer!
Maryann N.
Love the color! Helps out baby know it’s time to sleep!
Amanda B.
My baby loves her new sleep sack! She feels comforted by the light weight on her chest, and I feel comfortable that there isn’t too much weight on her little body. Buying the next size up for when she grows more!
olivia g.
Keeps him a little warmer, but sleep hasn’t improved. We’re well over a week with my 6 month old wearing it.
DANIELLA G.
So cute and comfy!
Emily P.
I’m sure this is a great product however my son doesn’t like it as he doesn’t like most swaddles it’s sacks
Katherine V.
My LO is 11 weeks old and still has a terrible startle reflex. He doesn't like to be swaddled and gets out of it almost every night. This does not settle him enough to sleep through the night, but it works well enough to use for naps! We will try sleeping through the night in it again when he is a little older.
Josephine B.
Gave as a gift and the mom to be loves it!
Rebecca L.
As soon as we couldn’t swaddle, our baby stopped sleeping through the night. Using this sleep sack is the only way she sleeps through the night now. But when we use it, she sleeps for 11 hours. It’s fantastic. Definitely worth the money.
Emily A.
So soft. Perfect tool to help my little one sleep well at night
Grace C.
Amazing!! We’ve used a different brand of sleep sacks but my one year old could get his arms out of them and get stuck so they didn’t seem safe. These fit nice and snug (not too snug) and seem way more safe! Plus he seems to settle down more quickly in these!! I love the bamboo lightweight one it is perfect for us!
Mitsie S.
Love these sleep sacks! I’ve tried different kinds and some even more pricey and the nested bean sacks have been just the right amount of added support and comfort for the baby while she sleeps. I plan to use these with all my future kiddos!
Irene C.
Our 5-month-old daughter takes longer naps during the day and seems to sleep more deeply at night. She gets happy when she knows she is to sleep in her Zen Sack.
Elizabeth H.
I don’t think it’s making too much of a difference for our little guy… he does get tummy issues and seems to be teething, so that may be why it doesn’t seem to be working too well for us.
Christina G.
My baby sleeps so well with the sac on. Definitely a game changer
Nicole K.
ONE DAY! It took one day to get my girl to sleep alone. I'm so happy I took the chance and bought this sleep sack!
Megan W.
My son sleeps amazing!
Bridget S.
Both our babies have love the Nested Bean sleep sacks! My second has grown much faster than our first, so we got the second size up and it’s perfect! She’s been sleeping great in her bassinet with no issues!
Mary B.
Great quality . So far so good :)
Brittany T.
My daughter sleeps like a log in this Zen sack! It has definitely been working wonders!

Jamie B.
Wonderful experience! My son had recently started breaking out of the Miracle Blanket. The Nested Bean was a perfect transition from the Miracle Blanket. He likes to chew on his fingers to self soothe and the Nested Bean allows him to do that. He also likes to play with the little bean on the front when he's awake in his crib. He's 5 months and sleeping great so far.
Amanda S.
Not sure it helped my little one sleep better.
Casey
Our 3-month-old was sleeping in 6-hour stretches but we wanted her to sleep 8+ hours since I was going back to work. We bought this sleep sack and by night 3, she was sleeping 8-9 hours per night.
Jessica M.
My 5.5 month old would be so restless during the night after two hours and would move himself to the point where he would kick the sides of the crib and wake himself up at night. With the sleep sack I can honestly say he no longer moves as much and gets a better quality sleep at night. And he is definitely sleeping longer as well and goes a longer period of time without waking up. He already can sleep between 5 and 6 hours. With the sack he goes 7 to 8 hours before waking up to be fed.
Sawyer R.
Very nice quality sleep sack! Love the color too. However, transitioning our little one out of the swaddle hasn’t been easy. Hoping in the next few weeks we can get our little one to sleep with the sleep sack!
Kathy P.
My baby sleept through the night since 6 weeks up to 8 months. From 8 months to 9 months he would wake up in the middle of the night for 2 hours. I literally had enough when one night he was up from 1am-4am and I gave this a try. My baby has been sleeping from 8:30pm-7 am ever since. I’m writing this after making my second order and realized I missed my 15% discount on it :/ but i have no regrets.
Jose J S.
We love this sleep sack! It’s wonderful. The ease in which the sleep sack comes on and off is worth it all on its own. The material is soft and durable, too! We have the cotton and the winter one. I love that it’s spacious enough while not being too loose. I also like that the weight isn’t throughout the entire sack but is just located in one area. Baby and parent approved!
Barbara M.
Our 4 month old is sleeping great with his new sleep sack! Sleeping from 8pm to 7am! Thank you!

She will go at least 3-4 hours straight without waking up. She will start tossing and turning when she is about to wake up to nurse.
I say get it! I wish I would have gotten one when she was a newborn and started her in the sleep swaddle. If you buy the swaddle one, not that the arms unzip so it can also be worn as a sack. Which is really convenient to transition. I tried the swaddle and she doesn’t like being constrained at this point. But we use it as an extra with the arms unzipped.
I also purchased the footies for when she is a little older so she has that to transition to next.

I love the sleep sacks but my god the shipping to Canada is atrocious. Took over a week for it to even be shipped. Been 3 weeks since I ordered and still hasn't arrived

It is a great sleep sack but it smelled really bad when I opened it. I washed it and it actually made the entire load of laundry smell so I had to re wash everything

I have used nested bean sleep sacks and onesies for all 3 of my kids. Love the quality of them and my kids love them too.

This has transformed my 2 month old regular sleep from 5 hours to 7 hours ! Love the rest he’s getting !
Eyleen V.
My baby would not nap more than 20-30 minutes per nap during the day, ever since we got this weighted sleep sack she sleeps over an hour. So thankful for this! Its perfect. 10/10 recommend

I love these sleep sacks and the purple one is beautiful! Super soft and cozy and my little one seems to like it too. Best part is no velcro to wake them up!
Kayla C.
Love it! Game changer for getting 12 months old to sleep on her own at night!!
Shivani V.
Baby looks a little uncomfortable in this
Andrew M.
We love our nested bean sleep sack! Helps our baby sleep though the night.

I honestly can’t believe it works as well as it does!
I NEVER write reviews. Usually it really isn’t worth my time but here I am…
My son started flipping over on his stomach and we had some hard nights trying to get him used to sleeping while not being swaddled. Once the sleep sack came in I was really hoping it would work. He’s 3 1/2 months old and the first night he slept through the night! I thought maybe it was a coincidence.The next week he would either wake up once at night or sleep through the night.
The only thing I wish they had was maybe a sleep sack that had the weight on both the tummy and back. Or something like that because I don’t always know if he’ll fall asleep on his belly or back at night.
Overall a great product!

I bought Nested Bean sleep sack for my baby’s naps in the daycare. I got 6-15 months size for my 5 month old very tall baby. The material was thick but very comfortable and not hot.
Allison W.
He might sleep on his side/back at times but these zen sacks have been a life saver!
Mannin P.
Got it for my 9 month old and she’s sleeps great in it!

We transitioned our 2 month old into this Nested Bean Sleep Sack and he began to sleep a continuous 8-10 hours a night! The first night he woke up after 5 hours but with a simple rock and forth, he went back to bed and stayed asleep for another 3 hours. On the second night he stayed asleep and he’s been sleeping through the night ever since. We’ve been using this Sleep Sack for about 2 weeks now and it has been so great!
Natasha K.
The sleep sack seems to be working well! There are still nights when he's up a lot with teething, but when our sleep sack needed to be washed and he had to go a couple of nights without it, he woke up a lot more often. Now he actually puts himself back to sleep if he wakes up at night! We just bought a second so we don't have to worry about one being in the wash at bedtime...
Erika A.
Our baby boy loves the nested bean sack. He transitioned to this one after the swaddle. Washes great and is very soft.
Fife K.
These sacks are so easy to use and big. My son loves them.
Ashton Caroline A.
Excellent customer service! 10/10! The Zen Sack tore at the seams after a short period of time, and with a few pictures, I was able to get a new one at my house in a few days. It made me feel great to invest in nicer sleep sacks when the company backs up their products like that! This was a fluke as we have had several others that withstood lots of use!
Krista M.
We have seen a significant difference when our baby sleeps in his nester bean. He is much more relaxed and calm.
Maggie D.
She loves her sleep sack and it calms her down quickly.
Miranda S.
Thought the little weighted part would be a little heavier. It so far hasn’t done anything for my daughter. I wish it had worked out for her!
Becky H.
The first night in the sleep sack was rough. Baby girl kept waking herself up. Since then she is responding well and loving the sleep sack, she started sleeping with her arms up and has been sleeping later too.
Emily L.
I love nested bean sleep sack. It was recommended by my daycare teacher because they other parents used it and found the difference. These are much better to calm down my little one who was terrible at sleeping. The weight actually helped to put him to bed because that’s what I did with my hands on his little chest before I started using nested bean. I purchased 4 already and I will definitely purchase more until my baby is transitioning to blankets
Eileen V.
We love Nested Bean! We started with the Zen One sack to transition out of swaddling and now she’s 7 months old and in her big girl sleep sack and LOVES IT! Rolls on her tummy to sleep and loves it.
Kaitlyn P.
The pattern is amazing and the quality is great! Does it help our little one sleep better, I can't really tell. It's definitely not the miracle we were hoping for, but it's not hurting anything.
Faasefuout S.
Best purchase I’ve made for my needy baby! I only wish I bought this sooner (like one baby ago) because my first child also could have benefited from this. Was hesitant that it would even work for us but soooo glad it does!
Jessica W.
Our baby girl loves the nested bean sleep sack! She immediately went to bed easier and stayed asleep longer!
Maryann N.
Love the color! Helps out baby know it’s time to sleep!
Amanda B.
My baby loves her new sleep sack! She feels comforted by the light weight on her chest, and I feel comfortable that there isn’t too much weight on her little body. Buying the next size up for when she grows more!

Keeps him a little warmer, but sleep hasn’t improved. We’re well over a week with my 6 month old wearing it.
DANIELLA G.
So cute and comfy!
Emily P.
I’m sure this is a great product however my son doesn’t like it as he doesn’t like most swaddles it’s sacks
Katherine V.
My LO is 11 weeks old and still has a terrible startle reflex. He doesn't like to be swaddled and gets out of it almost every night. This does not settle him enough to sleep through the night, but it works well enough to use for naps! We will try sleeping through the night in it again when he is a little older.
Josephine B.
Gave as a gift and the mom to be loves it!
Rebecca L.
As soon as we couldn’t swaddle, our baby stopped sleeping through the night. Using this sleep sack is the only way she sleeps through the night now. But when we use it, she sleeps for 11 hours. It’s fantastic. Definitely worth the money.
Emily A.
So soft. Perfect tool to help my little one sleep well at night
Grace C.
Amazing!! We’ve used a different brand of sleep sacks but my one year old could get his arms out of them and get stuck so they didn’t seem safe. These fit nice and snug (not too snug) and seem way more safe! Plus he seems to settle down more quickly in these!! I love the bamboo lightweight one it is perfect for us!
Mitsie S.
Love these sleep sacks! I’ve tried different kinds and some even more pricey and the nested bean sacks have been just the right amount of added support and comfort for the baby while she sleeps. I plan to use these with all my future kiddos!
Irene C.
Our 5-month-old daughter takes longer naps during the day and seems to sleep more deeply at night. She gets happy when she knows she is to sleep in her Zen Sack.
Elizabeth H.
I don’t think it’s making too much of a difference for our little guy… he does get tummy issues and seems to be teething, so that may be why it doesn’t seem to be working too well for us.
Christina G.
My baby sleeps so well with the sac on. Definitely a game changer
Nicole K.
ONE DAY! It took one day to get my girl to sleep alone. I'm so happy I took the chance and bought this sleep sack!
Megan W.
My son sleeps amazing!
Bridget S.
Both our babies have love the Nested Bean sleep sacks! My second has grown much faster than our first, so we got the second size up and it’s perfect! She’s been sleeping great in her bassinet with no issues!
Mary B.
Great quality . So far so good :)
Brittany T.
My daughter sleeps like a log in this Zen sack! It has definitely been working wonders!

Wonderful experience! My son had recently started breaking out of the Miracle Blanket. The Nested Bean was a perfect transition from the Miracle Blanket. He likes to chew on his fingers to self soothe and the Nested Bean allows him to do that. He also likes to play with the little bean on the front when he's awake in his crib. He's 5 months and sleeping great so far.
Amanda S.
Not sure it helped my little one sleep better.
Casey
Our 3-month-old was sleeping in 6-hour stretches but we wanted her to sleep 8+ hours since I was going back to work. We bought this sleep sack and by night 3, she was sleeping 8-9 hours per night.
Jessica M.
My 5.5 month old would be so restless during the night after two hours and would move himself to the point where he would kick the sides of the crib and wake himself up at night. With the sleep sack I can honestly say he no longer moves as much and gets a better quality sleep at night. And he is definitely sleeping longer as well and goes a longer period of time without waking up. He already can sleep between 5 and 6 hours. With the sack he goes 7 to 8 hours before waking up to be fed.
Sawyer R.
Very nice quality sleep sack! Love the color too. However, transitioning our little one out of the swaddle hasn’t been easy. Hoping in the next few weeks we can get our little one to sleep with the sleep sack!
Kathy P.
My baby sleept through the night since 6 weeks up to 8 months. From 8 months to 9 months he would wake up in the middle of the night for 2 hours. I literally had enough when one night he was up from 1am-4am and I gave this a try. My baby has been sleeping from 8:30pm-7 am ever since. I’m writing this after making my second order and realized I missed my 15% discount on it :/ but i have no regrets.
Jose J S.
We love this sleep sack! It’s wonderful. The ease in which the sleep sack comes on and off is worth it all on its own. The material is soft and durable, too! We have the cotton and the winter one. I love that it’s spacious enough while not being too loose. I also like that the weight isn’t throughout the entire sack but is just located in one area. Baby and parent approved!
Barbara M.
Our 4 month old is sleeping great with his new sleep sack! Sleeping from 8pm to 7am! Thank you!

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.

-
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
