Finally my little one was able to transition from been swaddle to arms free, love it …
Megan E.
Love these for our 7 month old! We started with the zen swaddles but when he started breaking out of those and rolling, we switched to the sleep sacks. He still settled in to sleep and naps just as well and did great with the switch. The regular cotton is the perfect weight to keep him warm, but not hot. We had to get a second so we can keep one on rotation for nap time on laundry days! That double zipper is a life saver for early morning or middle of the night diaper changes.
Jaclynn M.
I truly believe my baby loves and would tell me if she could! She falls asleep fast and sleeps through the night, only waking up maybe once to eat and goes right back to sleep! Mama is feeling rested! So far so good! Thanks nestedbean!
Edwin R.
We just transitioned our 8 month old to her crib and we were having trouble with her waking up throughout the night and only going back to sleep once we put her back in the bed with us. In the last week that we've had the zen sack she's been mostly sleeping throughout the night AND staying in her crib!
Deidre M.
We love the Nested Bean sleep sack so much. Helps my baby get the rest she needs.
Tara P.
Very nice, well made product. Unfortunately it hasn’t worked any miracles with getting my little one to stay asleep.
Meryam J.
As much as I wanted to love this, it didn’t make a difference in his sleep, not really weighted or anything special. Just didn’t work for us
Mikayla L.
Since our baby has been 4 months old the use of this sleepsack is a game-changer! We went from having a colicky baby that wouldn't go to sleep till after 11 with a cry fit from 9 pm-11 pm at least, once we started using this sleep sack we were able to get our first night without a colicky fit and we left those in the past with the use of this sleep sack!
Kirsty H.
After trying what feels like a billion different swaddles we finally have a winner for arms up!
Pang W.
My daughter sleeps 11-12 hours every night because of Zen Sack Quilted!
Milah P.
Lovely sleep sack! My twins sleep well throughout the night :-)
Merlyn P.
Great products! I have 3 sleep sacks and baby loves them <3
Jana C.
I love these sacks. My daughter sleeps so nicely with it. It definitely helps babies to fall asleep easily and sleep well.
Velia N.
My 2 week old was breaking out of our swaddle we had for our last 2 kiddos and we needed something to comfort his sleep stat!! The first time was like magic, slept great and didn't wake himself up with the startle reflex. There have been some struggles with putting his arms down but I love the option of having his arms up if he wants comfort. Definitely recommend this product to anyone looking for a great quality swaddle.
Lindsey D.
Such a good product! This is the second one I’ve ordered and I couldn’t say better things about it. I’ll always recommend this brand for sleep sacks
Rae D.
We have used the sleep sack with my 5 month old for about a month now. I was super worried about the transition from being swaddled to her sleeping in a sleep sack but her Nested Bean made that almost perfect! I truly think we would have had a much harder time with the transition and with the 4 month sleep regression had it not been for the Nested Bean sleep sack! We already have the next size up because we will not be without this now!!
KAYLAN N.
Helps keep my baby asleep longer
Bonny W.
We tried several sleep sacks before finding the zen sleep sack by Nested Bean. Our girl now sleeps all night long in her crib ❤️ we loved it so much we just purchased the next size up.
Paula R.
This is a game changer!! Our almost 3 month old has gone from sleeping an hour at most in his bassinet to sleeping 4-6 hour stretches, since day 1 of using his sleep sack! We have been using this for almost a month now and he is starting to associate the sleep sack with bedtime, it’s the best!
Bailie B.
My boy absolutely LOVES this sleep sack!!! This is the 3rd NB product we’ve bought and every single time it has been worth it. I will say the 6-15m little weighted egg is definitely larger than I was expecting it to be but as he grows I’m sure it won’t seem as big!
For reference my LO is 5mo old, ~28”, and about 15lbs (7th percentile for weight, 95th for height) and it fits him great while still giving him room to grow!
Charlsey S.
My 9 month old sleeps comfortably in her nested bean sleep sack. She is a belly sleeper & this helps her feel more comfortable in her crib.
Jessica G.
Fits just right! My baby seems to sleep better with the weight in the chest area.
Elvira J.
My baby loves it and sleeps so well with it. She slept in the bassinet the whole night! Thanks so much for making this
Caitlin M.
Bought this for our 3 month old to prepare for arms free napping/ sleeping within the next few weeks to come and we love it! He sleeps great with arms up and can still reach his hands to self soothe (or buy me 5 minutes to get his bottle). Would highly recommend!
Alba A.
My 7 month old hadn’t slept through the night and we were so exhausted. I tried everything. As a last attempt, I bought the nested bean. Best 50ish dollars I’ve ever spent. Happy (and rested) household!
MAHFUJA M.
Very nice
Katherine B.
My little guy took a 3 hour nap one of the first days of wearing this sleep sack! Definitely going to keep using it and hope for similar results
jessica s.
We had this for our daughter and it was like magic for naptime. We gifted this to our friends and they look forward to trying it when their daughter is old enough
Caroline A.
My 3 months baby love it . Very comfy and cute
Jessica W.
I had spent about a month trying to transition my baby to sleep with arms out, and I'd have to wrap one arm in each night due to fussiness until he slept with this sleeping bag. It's wonderful and we love it. We used the swaddle version as a newborn so it made sense to move up to the sleeping bag. We live in Australia and it's worth waiting for shipping!
Videesha B.
Both this and none of my twins like it
Colleen T.
Baby loves this sleep sack! It buttons at top and very secure
Daramfon B.
I was really hoping thisbwould work. I've been using it for about a week and no difference. My 6 month old still wakes about every 3 hours. Very disappointed.
Marissa B.
This is night 4 in our new nested bean zen one sleep sack and my 4 month old is only waking up once throughout the night to eat. He's otherwise so calm and content as soon as I put it on him. It's obvious that he feels very comfortable in it and if sleeping so much better thank you nested bean!
Amber J.
This was our 4th Nested Bean sleep sack. I used one on my older daughter and have purchased 3 more. It helps my baby sleep through the night, the material is comfortable and safe.
Weronika J.
Did not see any changes in my baby’s sleep, it’s comfy material tho
Haylee S.
its not what I expected and doesnt seem to help with sleeping or comforting. I feel its just as all the other normal sleep sacks
Terra B.
After receiving our replacement bean sack, we are once again happy customers. Thank you nested bean for standing by your product and replacing a defective item. You have made our lives much easier!
Amber F.
It’s super cute and soft. However, it wasn’t heavy enough on my option and after using it 2 straight weeks, it didn’t work at all to soothe. Super disappointed and wishing I hadn’t purchase as I was looking forward to it helping my little, but did not live up to the reviews.
Amanda B.
I like it.. however I haven’t noticed any change with my 3 month olds sleep. I’m also not a fan of how high the neckline is
Tereza W.
These are my favorite sleep sacks. Daughter and son slept very well in them. So soft
Lauren H.
Super soft material! Seemed to definitely help my little guy at night! I ordered more.
Taylor S.
We’ve been using nested bean for 5 months now and it’s been the best decision ever made
Elizabeth C.
Amazing love this transitional sack from the new born to this one and that it will grow with my baby.
Ally A.
We love our nested bean sleep sack! Perfect thickness for our Florida baby!
So cute & cozy!
Emily H.
We have been using for over a week, and there is no difference….. we are still not sleeping
Monica T.
We had the standard zen sleep sack for our 4 year old when he was a newborn. We used it again with our newest baby. He outgrew the small size and loved it so much that we ordered the 6-16mo size but opted for the winter option. OH MY GOODNESS he loves it so much. It’s so soft and just the right amount of plush.
We bought the quilted material too but haven’t had a chance to use it yet because he loves the winter one so much!!
Ally A.
We love our nested bean sleep sack!
Kacey L.
We were looking for something to transition out of a normal swaddle because our little one likes his hands up. This has been the perfect swaddle for him!
Mason
My son absolutely loves it. He had been swaddled from birth, so when he started to roll over and break free from the swaddle I needed to find something to help him feel comfortable. I googled and googled until I was googled out, until I came across the Zen Sack. A color that’s soft on the eyes, and a diaper-changing friendly bottom zipper, this sack is a game changer for swaddle transitioning babies.
Danielle P.
We used Nested Bean classic with our first, and it was a game changer, so we knew we had to use it with our second!
Reychelle
Helps my little one rest through the night with the exception of 1 diaper change. I like that you can zip from the bottom just to free his legs and change him without him fully waking.
Emily H.
We LOVE this sleep sack!! Our daughter has slept through the night since our first time using it. She has also had some great naps in it. We put her in it with the bean on her back because she sleeps on her tummy. This makes her feel safe and like our hand is on her back. I would recommend this product to anyone who has a baby that likes to feel snug and secure (or any baby for that matter)!!
Jaclyn L.
We transitioned our baby when she was only eight weeks old, because if she woke up and was swaddled, she would freak out, and we’d have to get her out. Switching to the sleep sack she was able to now soothe herself back to sleep, and her nighttime sleep has extended to about 5 to 7 hours. The little egg does not weigh that much so parents who are afraid of any weighted blankets don’t have to be nervous. It’s also really easy to clean. Just throw it in the washing machine and dryer.
Beth L.
This product is AMAZING! I bought the classic Zen one for my granddaughter and it worked wonders! I highly recommend this product! Great quality also and shipped out of Missouri, so I like that it did not come from china! It is worth the price! I am going to purchase the larger size to have on hand when she out grows this one! You will not be disappointed!!
Rebekah W.
This is our second baby and second time using the nested bean sleep sack. Our 8 week old has been sleeping more restfully and longer stretches since using!
Ashley V.
Baby girl loves it, sleeps all night
Annette C.
My grandson would always sleep restless, especially for naps throughout the day. He would fall asleep holding/rocking him but as soon as you laid him down he would wake up...until I got him this sleep sac! From the first time he wore it he has slept longer and more sound than ever! My daughter swears by it! She said it has absolutely been a game changer!!
Grissel E.
My baby was struggling to sleep longer than 2hrs now he sleeps 4hrs sometimes 6hrs. Love it
Edna M.
It's amazing!
So far so good, she loves it.
The arm part was tight n same.. not for my baby.
Sharon S.
It seemed to help a bit. Nothing extraordinary. It may work for some babies more then others. The product was well made and was easy to use.
Not a negative review, just didn't help our baby. Doesn't mean it won't be the answer to another babies sleeping issues.
Love it!!
Susan V P.
Love the sleep sack…my grandson sleeps so well when he is snuggled in
Katie P.
We love our classic nested bean sleep sack! My son can’t sleep all night without his. We have used it since he was around 10 weeks old. He is now almost 8 months old.
Hope W.
This sack helped my baby transition from a swaddle in one night. Will recommend to everyone!
Pamela A C.
Love this product. The recipient loved it too!
Taylor T.
Our 2 week old is already quite the busy body. She prefers to sleep on her side & keep me up all night adjusting her! Since we got the nested bean, she has been sleeping on her back & sleeping very well. I am so thankful, total game changer.
Kerri B.
This was a birthday present for my granddaughter on her 1st birthday. She has slept in these since she was 3 months old and sleeps so well. She sleeps 12 hours at night. I know these sacks soothe her to sleep sound. Highly recommend
Lily M.
absolutely love! it is the only one we’ve ever used and the only one we ever will!
Kim
❤️
Ister
Useless.
Mel C.
Since the day I received it I put it on, loved the quality and soft material, and we saw the difference the same night! I do think I need to buy the bigger size now, he almost 2 months old but is 22.5-23in and 12 pounds, 0-3 months is the exact fit so I’m afraid he’ll grow out of it quickly. My husband and I are amazed with how fast and great it work for us and specially for baby.
Taylor M.
We love the nested bean! We have one in every size , comfy play and fits perfect . She sleeps great every night
Shari
Love it!! Great quality!
Holly S.
Both my babies have worn them and loved them!
Desyre P.
My baby got sick of the merlin suit unexpectedly. She started sleeping through most of the night in this sack. It keeps her warm and allows her to wiggle as much as she needs to. I have two but I think I need more!
Sharmila D.
Return is difficult
Jodi P.
Although the fabric and design is nice, this sleep sack has NOT helped my baby sleep better at all. I'm quite disappointed since I have tried every sleep sack on the market besides the Dreamland Baby brand which is too expensive for me. I really had high hopes of getting some sleep since my baby is already 10 weeks old.
Chloe F.
I figured it would be a slight difference in size compared to the small, which my daughter is growing out of. The medium is HUGE. I mean from the floor, it goes up to my waist (I’m 5’3”). I like the swaddles but I don’t think it really helps her sleep any better. The zippers are convenient. I don’t think I’ll buy another one unless they have a big sale.
Hansa B.
Love it!
Laura G.
Love the weighted middle, my son loves it. It is very soft snd comfortable.
Ivanna A.
My daughter absolutely loves this sleep sack.
Jamie R R.
Love the fabric and everything about it. Baby doesn’t like it :( wanted to return it but I took the tag off
Marissa A.
It does not help my baby sleep. I feel the sack is way to long for a one month old baby and the middle doesn't really resemble your hand
Brittany B.
I’ve loved these sleep sacks for both of my babies. It truly is the answer to getting your baby sleeping longer spans of time. Life saver!
Karen T.
Love these sleep sacks for their ease of use. Baby is in without bending arms, zipper opens sack up flat and baby loves the comfort of the weighted front. So easy.
Stacy H.
My now 4 YO daughter only slept in these. So many sleepless nights until I caved and bought one and I wound up buying multiple. So when I just had my son, I KNEW to buy. I now have 3 different kinds and all are life savers for those colicky rough and restless nights. I highly recommend this brand to all new parents!
KelseaMarie H.
Took longer then expected but he loves it
Chelsea S.
We loved our sleep sack! My little one sleeps so much better when wearing this. He has less awakenings and sleeps longer! I’ve gifted two of these to new mama friends already because I truly believe a good nights sleep is the best gift for any new mama! (And baby!)
Rosa D.
I was skeptical at first, but when my little one slept almost all night the first night wearing it (and every night since) I became a believer! Loving this sleep sack and already shared the website with a few friends with babies as well!
Hilarie C.
Got it hoping to finally have something to help my 10 month old sleep. While I like the design and the zipper opening, it has not helped at all with her sleeping.
EMILEE. G.
I’ve order from here before and has no problems with getting the correct thing I ordered but my last order I put in they sent me the wrong item. Just very disappointed because my son needs the zen ones and I ordered that but got the complete wrong order.
Lynnette M.
Perfect.
Diane H.
It was a gift so I have nothing more to say
Shauna S.
My grandson has slept so much better since using the sleep sack. The material is super breathable and washes well. I plan on buying more for him as he grows!

In and out is so easy. Love this sleeping sack.

Great quality also and shipped out of Missouri, so I like that it did not come from china! It is worth the price! I am going to purchase the larger size to have on hand when she out grows this one! You will not be disappointed!!

This is our second baby and second time using the nested bean sleep sack. Our 8 week old has been sleeping more restfully and longer stretches since using!

My grandson would always sleep restless, especially for naps throughout the day. He would fall asleep holding/rocking him but as soon as you laid him down he would wake up...until I got him this sleep sac! From the first time he wore it he has slept longer and more sound than ever! My daughter swears by it! She said it has absolutely been a game changer!!
Grissel E.
My baby was struggling to sleep longer than 2hrs now he sleeps 4hrs sometimes 6hrs. Love it
Edna M.
It's amazing!
So far so good, she loves it.
The arm part was tight n same.. not for my baby.
Sharon S.
It seemed to help a bit. Nothing extraordinary. It may work for some babies more then others. The product was well made and was easy to use.
Not a negative review, just didn't help our baby. Doesn't mean it won't be the answer to another babies sleeping issues.
Love it!!

We love our classic nested bean sleep sack! My son can’t sleep all night without his. We have used it since he was around 10 weeks old. He is now almost 8 months old.
Hope W.
This sack helped my baby transition from a swaddle in one night. Will recommend to everyone!
Pamela A C.
Love this product. The recipient loved it too!
Taylor T.
Our 2 week old is already quite the busy body. She prefers to sleep on her side & keep me up all night adjusting her! Since we got the nested bean, she has been sleeping on her back & sleeping very well. I am so thankful, total game changer.

This was a birthday present for my granddaughter on her 1st birthday. She has slept in these since she was 3 months old and sleeps so well. She sleeps 12 hours at night. I know these sacks soothe her to sleep sound. Highly recommend

Useless.

Since the day I received it I put it on, loved the quality and soft material, and we saw the difference the same night! I do think I need to buy the bigger size now, he almost 2 months old but is 22.5-23in and 12 pounds, 0-3 months is the exact fit so I’m afraid he’ll grow out of it quickly. My husband and I are amazed with how fast and great it work for us and specially for baby.

Shari
Love it!! Great quality!
Holly S.
Both my babies have worn them and loved them!
Desyre P.
My baby got sick of the merlin suit unexpectedly. She started sleeping through most of the night in this sack. It keeps her warm and allows her to wiggle as much as she needs to. I have two but I think I need more!

Return is difficult

Although the fabric and design is nice, this sleep sack has NOT helped my baby sleep better at all. I'm quite disappointed since I have tried every sleep sack on the market besides the Dreamland Baby brand which is too expensive for me. I really had high hopes of getting some sleep since my baby is already 10 weeks old.

I figured it would be a slight difference in size compared to the small, which my daughter is growing out of. The medium is HUGE. I mean from the floor, it goes up to my waist (I’m 5’3”). I like the swaddles but I don’t think it really helps her sleep any better. The zippers are convenient. I don’t think I’ll buy another one unless they have a big sale.
Hansa B.
Love it!
Laura G.
Love the weighted middle, my son loves it. It is very soft snd comfortable.
Ivanna A.
My daughter absolutely loves this sleep sack.
Jamie R R.
Love the fabric and everything about it. Baby doesn’t like it :( wanted to return it but I took the tag off
Marissa A.
It does not help my baby sleep. I feel the sack is way to long for a one month old baby and the middle doesn't really resemble your hand
Brittany B.
I’ve loved these sleep sacks for both of my babies. It truly is the answer to getting your baby sleeping longer spans of time. Life saver!
Karen T.
Love these sleep sacks for their ease of use. Baby is in without bending arms, zipper opens sack up flat and baby loves the comfort of the weighted front. So easy.
Stacy H.
My now 4 YO daughter only slept in these. So many sleepless nights until I caved and bought one and I wound up buying multiple. So when I just had my son, I KNEW to buy. I now have 3 different kinds and all are life savers for those colicky rough and restless nights. I highly recommend this brand to all new parents!
KelseaMarie H.
Took longer then expected but he loves it
Chelsea S.
We loved our sleep sack! My little one sleeps so much better when wearing this. He has less awakenings and sleeps longer! I’ve gifted two of these to new mama friends already because I truly believe a good nights sleep is the best gift for any new mama! (And baby!)
Rosa D.
I was skeptical at first, but when my little one slept almost all night the first night wearing it (and every night since) I became a believer! Loving this sleep sack and already shared the website with a few friends with babies as well!
Hilarie C.
Got it hoping to finally have something to help my 10 month old sleep. While I like the design and the zipper opening, it has not helped at all with her sleeping.
EMILEE. G.
I’ve order from here before and has no problems with getting the correct thing I ordered but my last order I put in they sent me the wrong item. Just very disappointed because my son needs the zen ones and I ordered that but got the complete wrong order.
Lynnette M.
Perfect.
Diane H.
It was a gift so I have nothing more to say
Shauna S.
My grandson has slept so much better since using the sleep sack. The material is super breathable and washes well. I plan on buying more for him as he grows!
Karen T.
In and out is so easy. Love this sleeping sack.
Kayla D.
It works wonderfully for my baby girl. She sleeps all night.
Heather
Absolutely amazing and a life saver!
Frequently asked questions
-
How much weight is in the Zen Sack® Classic sleep sack?
All Zen sleep sacks feature a built-in Cuddle Pad™, which weighs just 30 grams (Small size) 60 grams (Medium size) and 90 grams (Large size and distributed across the chest). Our baby sleep sacks are safely weighted in key areas as opposed to all-weighted sleep sacks or weighted blankets, which the AAP has deemed unsafe for infants.
-
What’s the difference between Nested Bean weighted baby sleep sacks products?
Nested Bean offers a variety of sleep sacks, all of which are designed to calm like your embrace: Zen Sack® Classic, Zen Sack® Premier, Zen Sack® Winter and Zen Sack® Quilted. The difference between our weighted sleep sacks is the fabric used for construction. Zen Sack® Classic is made from 100% breathable cotton, and is perfect for year-round use. Zen Sack® Premier ,made from 70% rayon from bamboo for luxurious softness and 30% cotton for strength, is lightweight for warmer temps. Zen Sack® Winter is made from 100% cotton, with a 2.5 TOG and heavy poly-fiber filling for colder weather. And Zen Sack® Quilted is a cozy transitional sleep sack, for when temps start to drop.
-
Are Nested Bean weighted baby sleep sacks safe for babies who roll over?
All Zen Sack® sleep sacks were designed for rollers and tummy sleepers; they help babies get longer, more peaceful sleep through all growth stages. The Small and Medium size sleep sacks have a gently weighted Cuddle Pad™ on the front that 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 weighted center on baby's back for uninterrupted comfort all night.
-
What is the Cuddle Effect™—and how do Nested Bean sleep sacks trigger it?
The Cuddle Effect is a proven metabolic response that babies experience when they are held, that triggers relaxation and well-being, improves sleep and promotes healthy development. Research on Deep Touch Pressure (DTP) shows that babies experience the Cuddle Effect when they feel gentle pressure in the places you naturally hold them. Nested Bean sleep sacks are designed with gently weighted Cuddle Pads™ that calm like your embrace and trigger the Cuddle Effect for longer sleep.
-
Do Nested Bean weighted sleep sacks meet industry safety standards?
Nested Bean baby sleep sacks adhere to all Consumer Product Safety Commission guidelines around product construction, flammability and more. The Cuddle Pad™ in our sleep sacks is self-contained and cannot cause overheating, and the gentle weight does not restrict movement: For example, the Zen Sack™ sleep sack is safe for tummy sleepers, rollers and side sleepers.
-
When should you start using a Nested Bean sleep sack?
Once babies start rolling, swaddling stops—and it’s time to transition to a baby sleep sack. Only Nested Bean sleep sacks contain Cuddle Pads™ that are gently weighted to ease the transition from swaddle to sleep sack, so babies experience uninterrupted comfort and longer sleep.
-
How long does it take Nested Bean sleep sacks to work?
As with all our gently weighted Zen Sleepwear™, most parents report that our baby sleep sacks improve their baby’s sleep in 1 to 3 nights.
-
What is TOG—and how does it differ between Nested Bean sleep sacks?
TOG is a measure of thermal insulation. It is a commonly used term the textile industry to indicate how warm clothing is. The higher the TOG in baby sleep sacks, the better thermal insulation it provides and the warmer it is. For example, the Zen Sack® Classic sleep sack has a TOG of 0.5, perfect for year-round use. The bamboo Zen Sack® Premier sleep sack has a TOG of 0.3, for warmer weather. The Zen Sack® Quilted sleep sack has a TOG of 1.0, great as temps begin to fall. And the Zen Sack® Winter sleep sack has a cozy TOG of 2.5, just right for chilly nights.
-
What is the Grow-with-Me feature of Nested Ben sleep sacks?
Nested Bean sleep sacks contain 2 sets of snaps on the shoulders. The bottom snap offers a snug fit, while the top snap offers more room as your baby grows.
-
How do Nested Bean sleep sacks hold up in the washing machine?
All Nested Bean weighted baby sleep sacks are made of the highest-grade fabrics, and are designed to be super durable and withstand multiple washings. To protect the fabric quality, we recommend washing our baby sleep sacks in cold water, on a gentle cycle and tumble dry on low heat.
