Rebecca B.
There was no change with my son’s sleep, he’s still waking up 2-3 times a night. It’s nice quality sleep sac, just didn’t work for us.
Mallory R.
This is such an amazing purchase! My little one would not sleep in her bassinet at all without this. Tried this sleep sack and she slept in her bassinet ALL night on the first day of trying this. Wonderful purchase!!!
Jagoda B.
I was hesitant but this has definitely helped our 1 month old with her sleeping. She’s so much calmer! Thank you!!
DeAna N.
These work so well for my 3 month old. She would not sleep alone for more than 10 minutes and these have helped her transition from contact sleeping and napping to her bassinet and then to her crib. I don't know what I would do without these. Love them!
Marisol M.
Easy ordering process and it’s our baby’s favorite sleeper! I ordered two!!!!
lisa p.
I have to admit... he sleeps better and longer : )
Im a happy mama!
Sam B.
This has been such a game changer to our little one at night! So thankful for this sleep sack!
brooklyn d.
completely changed how my daughter sleeps at night! she sleeps on her own in her crib every night through the night now and i’m so thankful. this momma missed having room in her bed
Kaitlyn F.
Awesome stuff
Lindsey A.
Have tried several different swaddles and sleep sacks and our baby loves this one so much! He started sleeping longer stretches once we tried these they’re awesome!
Danielle S.
It's great
Nicolette R.
First time mom here, and we are on our second sack now, plan on purchasing the next size up after. Nights wouldn't be the same without it.
Kelby W.
Love it! My baby went from waking 3-4 times to one wake up. During that one wake up, he’s much calmer than before. Wish I would’ve gotten this sooner.
Haley R.
Baby girl has been sleeping much better in the night!
Abigail B.
Love nested bean
Pratiksha K.
My baby sleeps like a baby!!
Amanda L.
Had the best experience with our sleep sacks! They fit perfectly and I love the multiple button size option.
Candice I.
Great deff helps my baby sleep better thank you!
Mimi Q.
I was very skeptical in buying! My baby was waking up 3 times a night from 10pm-6am! we were very tired! I gave in and bought this sleep sack and I’m thinking eh it won’t change anything I’m sure but within 3 days or so my baby’s stretches slowly went longer!! the first long stretch was 4 hours when we never got more than 3 then it went to 5 hours! Last night she finally gave us a 6 hour stretch before feeding once and then going back to sleep in her sack!!! we love this!!!!
Cassie W.
Worked the first night for our 5 month old! He still wakes up occasionally but I think this really helps him get back to sleep quicker and more comfortably.
Janelle D.
It’s really big for my 2 month old so I can’t really tell if it works. She doesn’t like it. Material is nice tho. Wish I ordered the sac instead.
Teresa K.
Love them
Logan W.
Amazing!
Stacy C.
Very soft and my little one loves it! I love the button shoulders very easy to put on and take off
Miriam C.
My one month old went from sleeping 3-4 hrs to now 4-6 hours! And he is exclusively breastfed only so for mommas breastfeeding, you know this is great!
Catalina K.
I love(d) the sleep sack so much! It immediately helped my son regulate his sleep after a 3 month sleep regression. Unfortunately we went out of town and we left it at the hotel in another state. I’m devastated but I’ll be purchasing another one again hopefully soon when they go on sale haha. Thank you again
Theresa G.
We love Nested Bean! We started our daughter in the infant Zen Swaddle, moved into the medium Zan Sack and are soon graduating to the large size. She sleeps so well in this product and always has!
Reyahope S.
It unfortunately doesn’t work for my baby. He just rolls around too much. He doesn’t consistently sleep on either his bath or stomach, so I’m unsure of what side to put the weighted egg on. The material is soft and comfortable though. It’s otherwise a nice sleep sack.
Ricca Z.
My grandson loves it.
Christine S.
My daughter is 5 months and loves this sleep sac. No more sleepless nights!
Kaylen S.
Helped our baby sleep and has worked wonders for us! Highly recommend.
Casey B.
Borrowed one of these when my daughter was starting to be swaddled without a blanket. My daughter initially did like the weighted portion of it. It did appear to give her a sense of calm while she slept. Now that she is getting older, she is not a fan of the bigger sack (for her age) because she is not able to roll on her own because of the fabric. Will be passing this along to my friends in order for them to use for their littles!
JOAN C.
my grandson sleeps great in it
Danielle S.
My baby loves this sack! It has helped her get longer stretches of sleep
Jewely D.
So far my 5 month old loves it! She gets long stretches of sleep!
Amanda C.
Sack is good exchange process not so easy
Michele B.
I love these sleep sacks. They helped my little girl sleep through the night.
Bailey G.
We love this sleep sack!
Lucy P.
We love our Nested Bean sack! It definitely has made a difference with our little guy who co-slept for his first year. Now he's sleeping in his crib all night.
Vianeth R.
I love Nested Bean sleeping bag! Super comfortable and high quality fabric. My baby loves it too! Highly recommended,
Samantha E.
This word wonderfully
Arrielle T.
I love this sleep sack. It's lightweight but keeps my baby warm. I went with the classic because I can add a light blanket if it's super cold but I haven't really needed to. It helped a lot with my daughters sleep regression, especially since she got very clingy during it.
Kevin C.
Love your product. I have been using it with all my grandchildren. It really does help them sleep better.
Thank You!!
Monica A.
We love the bested bean, this is our 4th one we have owned and continue to buy the best size up! We were saddened to have this one arrive with a stain on the inside which did not come out when we washed.
Mary L.
Noah loves it!
Jordan S.
Hasn't done much of anything to help our little one sleep better through the night. Was hoping this would keep her from frequent night wakings, it didn't work. The sleep sacks are nice material and easy in and out, but no sleep improvement.
Diane O.
It makes a big difference in his sleeping pattern.
Maribeth L.
After rave reviews from my daughter and niece about the Nested Bean, I purchased this one for my nephew and his wife for their baby shower.
Josiah C.
Helps my son get to sleep and stay asleep! We were gifted the 0-6 month one, ever since we have used the nested bean sleep sacks for bed time.
Celina E.
Its nice
Suzanne F.
We love nested bean! It’s soft, not too thick and lightly weighted to help my toddler sleep through the night! Very pleased!
Cheryl M.
My daughter started using this sack at 7 weeks on my grandson at the advice of a friend. He hated the swaddle. Been a couple of weeks now and it sure has made a difference. Baby sleeps all night in his bassinet with only one night feed then right back to sleep. Need to order another in case my daughter forgets to wash!
Jenny S.
Love it!

I’ve used these sleep sacks since my twins were 4 months old. They’re great and work well for them. I will continue to use them until, I can’t!
Amanda C.
Love this so much! I notice a difference in my little one's sleep when we don't use the weighted sleep sack for her. She is the only one of my babies who sleeps through the night and the only thing we did differently was try this product!
Makla T.
My child sleeps so hard and well whenever we zip him in his sleep sac, we love it! It has truly changed our lives.
Maria R.
I have used the 3-6 months
Cournarier W.
My baby sleeps all night with her sack ! We love it
Alysia F.
I tried lots of different sleep sacks and swaddles with my LO, but the only one he like was the Nested Bean ones. I definitely recommend Nested Bean to everyone! This family loves them!!
Megan K.
The product is fine, it seems well made but hasn’t helped my baby at all. We’ve been using it for a week but he continues to wake 3-5 times a night. I also paid extra for the 1-2 day shipping and didn’t receive the product for 10 days. The customer service was fine, they refunded me a couple dollars since its didn’t arrive on time. Over all, not impressed with our experience.
Terri P.
My grandson sleeps great in this sleep sack.
Roman T.
Little bit expensive!
Olivia C.
Quality fabric but the weight has not changed sleep for the little one. I do like not having to squeeze his arms through the little holes but rather button in the top
Laura M.
Love it. Our baby loves wearing it every night and sets to tone to have her sleep!
KRYSTEN C.
We love nested bean! Have been using them since baby was born!
Mercedes R.
Great!
Adalida W.
Bought the sleep slack in an attempt to help my daughter sleep longer stretches, but it only made it worse. Will be returning.
Nancy E.
I just bought this for my sons baby. Not due until July . My daughter used this for her little girl. She’s 1 and half and now she uses it like a blankie. My daughter came to visit and she cried because my daughter forgot it at home. I’m sure my daughter in law will love it for her baby.
Marissa M.
Love this sleep sack! Even helps my side sleeper at night
Kari B.
The sleep sack was well made and good quality and nice soft fabric. It didn’t improve her sleep though so we are still on the hunt for something that helps her stay asleep.
Melissa W.
My daughter falls asleep a lot quicker even during her night wakings.
Katlyn M.
Been using it for about 2 weeks now and Child isn’t sleeping any better than before. May not be worth $60
Christina D.
Love it!!
Christina D.
I was nervous that my 11 month old wouldn't sleep thru the night since we originally using a dreamland weight sleep sac. But the transition to this one has been amazing. Love love love it!
Kyleene J.
My son is 2 months old and he did not like the sleep sack at first, After a couple days he was ok with it. Now he sleeps 4-6 hrs. I’m very happy
STEPHANIE S.
Excellent product!
Katrina M.
My son loves this great for belly sleepers.
Jamie H.
Works wonders for my baby when she fights sleep and wants to be held when taking naps. She also sleeps throughout the night at 2 months old! Helps promote restful sleeps. I would recommend to anyone
Jan R.
Little man sleeps all night in his nested bean zen sack! We found them when my granddaughter was born and they have been a “must have” since then.
Macey S.
We love our nested bean!
Melissa E.
The zen sack hasn't sleeps our baby sleep. Its been a week and a half and still no improvement on sleep.
Abby S.
Before using this sleep sack my son would sleep 2-3 hours then wake up, now he sleeps at least 5-7 hours straight. The first night using it he slept 7 hours I could not believe it! Plan to buy the next size up!!
Tara M.
We are on night 4 of very good sleep. This is my girl's first sleep sack from coming out of a swaddle at 5 months. She even likes sleeping on her tummy! Material is super soft.
Kelly P.
I love that it snaps up top and zips all around so it’s easy to on and off. The only thing I wish this sleep sack had was the option to swaddle. I know they have the zen one sack but that has mesh on the arms and I would like something that covers arms during the cold months
Shanelle D.
It’s not that I dislike it; it’s obviously a quality product and is very cute and nicely made. It’s that my baby hates it. He just hates swaddles or anything that restricts his legs. We’ll keep it because it’s too big of a pain to send back and maybe he’ll be game for using it some day, or we’ll gift it to someone else maybe, but yeah. Had high hopes it was going to help and those hopes crashed and burned.
Chelsea T.
My baby did not love being swaddled. From the time she was big enough to use the Nested Bean sleep sack, she has. We love them, and she sleeps great! We will continue to size up until she can’t/wont use them anymore!
Laura C.
Love it! My baby hates swaddling but this is perfect for him. Sleep getting longer. Thank you!
Bella K.
Our baby was struggling the transition to her own crib at night, I had someone recommend this product. I was hesitant on the price but we received one as a gift and this is the best sack we’ve used. Our baby hasn’t woken up during the night to come back into our room. She’s in her crib all night long!
As pictures she’s a tummy sleeper, so being reversible was perfect for my little one!!
10000/10 recommend
Susan W.
My granddaughter absolutely loves her nested bean sack! We won’t buy anything else.
Maylin M.
Love the way it fits! And most of all how well my baby sleeps in it.
Taylor H.
Hardly weighted to make any difference. Our child did not sleep better at all.
Annabell H.
It’s ripped. Only had it for 3 days
Joanna A.
Baby sleeps much better at night when she has this on
Beth F.
The material is extremely soft.
Kerry D.
This is our 5th sleep sack. Although, it did not magically work and it’s been a week and my son is still waking up 5x a night, the sleep sack is super cozy. The material is super soft & comfy, I want it for myself.! The weighted chick is super light weight, basically like one of those tiny bean bags. My son does like the sleep sack, I was just praying it would improve his sleep and it has not.
Sara H.
Love this!
Laurel L.
On the left, is the Sleep Sack I just purchased for our 3rd child. On the right, is the Sleep Sack we used with our 1st & 2nd. You may be asking ‘Why is is so worn, dirty & ugly?!’ It’s because our 2nd ADORES it and even at 4 years old, it’s still her equivalent to a baby blanket. She still cuddles with it when she sleeps, when she’s upset or when she needs a little bit of extra courage. I recommend Nested Bean to all new parents because 1) it works within days and 2) it brings comfort well beyond the child wearing it. It is worth the price and is an investment. If you child doesn’t love it to death like my 2nd, it is easily gift able or can be kept as a keepsake for future use.
Olga ' B.
Didn't make any difference in sleep
Zachary I.
This sleep sack is freaking amazing!!! Our 2 month old has been sleeping consecutively for 6-7 hours ever since we put her in this. She's more rested in the morning and has been getting better during the day as well. I highly recommend purchasing this for your babies!!!
Sasha H.
We loved Nested Bean sleep sacks. We used this for our other son when he was a baby and noticed a big difference in the stretches of sleep we got from him wearing it. Our current baby has been going through the 4 month sleep regression pretty bad the last few weeks. We ordered this right away and last night we got a 6 hour stretch of sleep from him! Amazing compared to the 90 minute stretches we were getting the previous two weeks.
Rebecca B.

Our baby was struggling the transition to her own crib at night, I had someone recommend this product. I was hesitant on the price but we received one as a gift and this is the best sack we’ve used. Our baby hasn’t woken up during the night to come back into our room. She’s in her crib all night long!
As pictures she’s a tummy sleeper, so being reversible was perfect for my little one!!

Hardly weighted to make any difference. Our child did not sleep better at all.
Annabell H.

This is our 5th sleep sack. Although, it did not magically work and it’s been a week and my son is still waking up 5x a night, the sleep sack is super cozy. The material is super soft & comfy, I want it for myself.! The weighted chick is super light weight, basically like one of those tiny bean bags. My son does like the sleep sack, I was just praying it would improve his sleep and it has not.

On the left, is the Sleep Sack I just purchased for our 3rd child. On the right, is the Sleep Sack we used with our 1st & 2nd. You may be asking ‘Why is is so worn, dirty & ugly?!’ It’s because our 2nd ADORES it and even at 4 years old, it’s still her equivalent to a baby blanket. She still cuddles with it when she sleeps, when she’s upset or when she needs a little bit of extra courage. I recommend Nested Bean to all new parents because 1) it works within days and 2) it brings comfort well beyond the child wearing it. It is worth the price and is an investment. If you child doesn’t love it to death like my 2nd, it is easily gift able or can be kept as a keepsake for future use.

This sleep sack is freaking amazing!!! Our 2 month old has been sleeping consecutively for 6-7 hours ever since we put her in this. She's more rested in the morning and has been getting better during the day as well. I highly recommend purchasing this for your babies!!!

We loved Nested Bean sleep sacks. We used this for our other son when he was a baby and noticed a big difference in the stretches of sleep we got from him wearing it. Our current baby has been going through the 4 month sleep regression pretty bad the last few weeks. We ordered this right away and last night we got a 6 hour stretch of sleep from him! Amazing compared to the 90 minute stretches we were getting the previous two weeks.
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.
