We love the sack but this one is damaged after one wear. The zipper has pulled off of the sack itself. I wrote to customer service and have her to hear back.
Carmen B.
This sleep sack is perfect for comforting little ones as they drift off to dreamland :) highly recommend!
Jessica A.
Works great! Baby flales less! I can tell she feels much more comforted with the weather beans!
Gloria H.
This works wonders. Baby hates swaddles that don’t allow him to move his arms around and this was the perfect option.
Jennifer C.
Don’t understand why the large tag is on the outside but we love the sleep sack
Lisa P.
The material is so soft and our little guy loves this sleep sack! We’ve used these since he was a newborn!
Julia L.
First of all, it shipped so fast! Second of all she is FINALLY falling asleep in her bassinet and staying asleep when I put her down. Without the sleep sack she would wake up IMMEDIATELY when I put her down. I’m so glad I found this! I definitely recommend
Mark S.
When we ordered the Zen Sac Classic not we were hopeful, but weren’t expecting drastic results. We have been pleasantly surprised by how well it has worked. It took one night for our 8-month old to acclimate, but has slept through night since. She was previously waking up 3-5 times a night. Couldn’t recommend it enough!
Hunter H.
My daughter loves it!
Sierra S.
We love these! I work at an early learning center and we ordered these for our infant rooms; big hit with the babies and their families. I order them now as gifts.
Kaitlyn S.
100% recommend! It allows my baby to move his arms freely as he likes to. He is 6 weeks old and has been wearing the sack for about 2 weeks, and has slept through the night for the past 2 nights! 8 hours straight! I feel like a new person.
Monda W.
We really like the product overall. This particular sleep sack that we ordered has a zipper that gets caught and is difficult to maneuver. Other than that, the product is great.
TerryAnn C.
Love it! Took a week or so to adjust but now our baby is sleeping well in it without any issues
Shania C.
It helps her sleep better. But no drastic difference.
Megan J.
My daughter sleeps so good in these. She is almost 6 months old & sleeps like 9 hours with minor wake ups but these help put her back to sleep
Grace C.
My son does so well with these sleep sacks! We wear it backwards as he is a tummy sleeper and it has really helped his (and ours!) sleep!
Maureen S.
I’m a first time grandmother who babysits our now 5 month old grandson three days a week. We were having some difficulty with naps.
Since using the sleep sac our grandson is taking great naps.
Carrie S.
Trying it out for the first time tonight!
Krista M.
I love the zipper! So much better than down the middle, it makes putting it on and diaper changes to easy. The weighted patch on his chest is perfect, he grabs and holds it just like he does with my hand and goes back to sleep! Last night he slept from 6:50pm- 6:20am!!!! I've recommended it to everyone I know! Love love love
Cynthia W.
Love, Love, Love…First and foremost I Love how comforted my baby feels at night when he wears his Zen Pack. Such a tiny little thing sleeping all by himself and I know he feels more at ease at night. I initially purchased one Zen Pack to quickly realize I need a few on hand. My sweet spoiled his ZP after the second night so I put him in his Halo sack and it was not the same for him. His arm reflex stirred back up which startled him multiple times, his sleep was not peaceful. I truly think he gets to his REM sleep quicker and is there longer with the ZP on. Secondly, I’m able to get a few more peaceful zzzzz’s knowing he feels secure. Oh and I cannot believe how incredibly SOFT the fabric is. I wish I could have this fabric made in bed sheets. Seriously luxurious. (Little sweet has been using his ZP nightly for about 3 weeks prior to this review)
Beverleigh C.
I received a sample swaddle and gave it to parents to try out
The zen sac was a favourite for their three month old who was learning to “try” rolling over
Excellent will refer more parents in my sample try for night sleeping
Thank you
Jessica R.
Haven’t seen much difference
Aalya G.
My baby was waking up multiple times a night and needed to be patted back to sleep but with this sack on I can see him start to stir and then just go back to sleep himself. I think the weight makes him feel like someone's there next to him and he doesn't bother getting up. game changer!
Jennae L.
fits great and helps her sleep!
Kimberly H.
She loves it so I love it. The only thing I didn’t like was around 10 weeks she was strong enough to pull the bean over her face. we tried transitioning or arm out but she would pull the belly strap up and everything would scrunch up around her neck. her reflex was still pretty bad so arms free still wasn’t an option. We put her in a zippity zip for a few weeks and now she is back in her bean. Thank y’all for making this. Was sad to take that short break but it felt like the safer bet.
Tamarah M.
I purchased the Zen Sack Classic, and I was impressed with how soft and light weight the fabric is. It is warm enough for my baby and she seems to like it too!
Katie P.
My son still isn’t sleeping, cute design and very soft
Kristin O.
I love these and so happy there is a winter one. My little guy sleeps great at night in his. And I LOVE how I can put the beads on his back because he is a belly sleeper
April K.
Our son loves to be snuggled so we purchased the nested bean sleep sake and he has done great! The little bit of weight gives him the support and comfort he needs.
Patty S.
This is a gift for my grand baby. He has one already and loves it!
Leah K.
We love this sleep sack. It’s soft and warm for cool to cold weather but it’s breathable enough to work in moderate temps without making our roly poly too sweaty.
Ana L.
My daughter love it we have bought one ever since she was six months. She is now thirteen months old. She literally go and grabs it and hugs it before bed time.
Shannon G.
Great shipping time and wonderful product!
Rosalee Z.
Our son loves feeling our hand on his chest and he has done amazingly with these new sleep sacks! Swaddling stopped working when he began wanting to wiggle more. But swaddling helped him sleep so much!
Then I read about weighted sleep sacks! I love the design. I love the colors. My son loves sleeping in it.
Bonus: if you manage to forget, like I have done, to put them in it before bedtime, I have laid it on the crib (fully unzipped and unbuttoned) and placed my son inside it, zipping it up and buttoning it on without waking him up. It's amazing!
I have every intention on buying many many more!
Jennifer M.
We were terrified to start putting our little one’s arms out from the swaddle, but jeez, this sleep sack made it almost seamless! The very first night, I kid you not, she was sleeping like she’d had her arms out for months. The weighted chest helps prevent “the startle” and keeps her feeling calm. 10/10, buy this sack. And it’s much more affordable than other weighted sleep sacks! Love Nested Bean!!
Carol N.
This is our third one
We’ve been purchasing these as our Grandaughter grows from infant to now 10 months . She sleeps so well with it on and we are so thankful for the opportunity to have found this wonderful product !!
Lora V.
We really do love the sleep sack. But it didn’t help baby sleep. I wish this was the magic thing to help us all sleep better. But overall do love the sleep sack.
Amanda W.
My six month likes it well enough. It gives a light layer of warmth. We have been using it for about two weeks. I love the side zipper and the snaps on the shoulders.
Samantha S.
Great transition out of swaddling. Soft material and cozy for baby.
Stephanie Z.
Instead of my 3 month old waking up 5 times a night, she now wakes up 2 times a night ever since I bought the nested bean sleep sack! She falls asleep faster and I feel so much more rested. I ended up ordering 2 more to do less laundry! So happy she loves wearing it!
Mary M.
Well made very nice material. Soft but sturdy. Well worth the price.
Brittany P.
My little one LOVES it! She was always a great sleeper but lately her naps and sleep time have been shorter than usual and this helped it go back to normal! Highly recommend this sleep sack!!!
Robyn C.
This is my second purchase, my daughter outgrew her 0-6 month one, we’re on to the next size and we love them! We like this new design print too!
Deeana H.
Absolutely amazing. A must have for parents. Can’t say enough good things about Nested Bean Zen Sack!
Krysta F.
Love these sleep sacks! My daughter feels comforted and warm while she gets a good nights rest. Not sure if they run small or she is just tall for her age but at 10 months she fits in the 15 month size.
Carolyn B.
My son has been using it for a week now and we’ve definitely noticed a change with him sleeping longer stretches.. even while teething.
JESSICA W.
Very nice quality sleep sack.
Shelby C.
We love this sleep sack! My newborn does not like to be swaddle up tight and would rather have his hands up by his face so this worked super well
Danielle M.
Love this sleep sack! I even bought one for my pregnant cousin because she needs to have one too. Can’t go back to anything else now!
Katie
First night unswaddled, peaceful sleep! Only one wakeup, so far so good!
Lauren C.
So I bought this after reading reviews and was really hopeful that it would help my one month old daughter sleep a little longer at night. The longest she has slept without waking is just over 3 hours, which doesn't happen every night. Many nights, she wakes up every hour and a half. I haven't noticed much of a difference, if any, so far, though it has only been a few days. She doesn't seem to like it much, either. She's very squirmy and kicks her legs a lot in the sack. We'll see how it goes, but so far this hasn't done much for us.
Alysha K.
We love these sleep sacks! Our 3 month old uses it and our 21 month old uses the large size. They’re the best.
Carol B.
I have bought 2 nested bean products for my great grandson. He is sleeping so much better with them.
Abby R.
We started using the nested sack about a month ago. I have this one and the one that is cotton for colder weather. My almost 1 year old was waking up multiple times in the night because she was such an active sleeper. She would constantly roll around in her crib and eventually either hit her head against the rails or the crib or get in a uncomfortable position that would wake her up. After about 4 or 5 days of using these sleep sacks she stopped waking up in the night and would actually sleep in a little later than normal! We will be using these for as long as we can!
Oluwatosin A.
This company may have made the best customer service experience for me. The genuine care for the customer truly made me shocked. My package was lost in transit and I was immediately sent a new one with tracking information. Let's not forget the extra sleep this product gave us! Happiest Customer of November 2021!
Shannon J.
Love the fabric. Perfect for my 18 month old.
Jill M.
The quality of the product is great. My little guy isn’t sleeping any better. He’s almost 9 months old and wakes every 2-3 hours during the night, even with the sleep sack.
Kayla P.
material is nice. The concept is great. It just didnt do much for us as far as sleep improvement but we also thick into the 4 month sleep regression so who knows... I was hoping for better results.
Samantha B.
My 4 month old loves this sleep sack! I recently transitioned him from the swaddle to and was very concerned about disrupting his sleep. He slept through the night from the first night I put this on him!
Rachel L.
Love it. Soft and launders like a dream. Dries in machine well too!
Brittany S.
We went through two sleep transitions within a matter of days of each other. First, we had to stop swaddling as baby was showing signs of rolling over. Then, we had to move him out of his bassinet and into his crib as he was suddenly too big! After some awful, sleepless nights, I ordered the Nested Bean sleep sack and am so glad I did! We get a full 8 hours of uninterrupted sleep every night! I even catch our dog on the nursery camera going in to check on the baby after so many hours of sleep. :) Baby is 10 weeks now and we have been using the sleep sack for almost two weeks. Love it!
Bridgette H.
My twin girls love their zen sacks! They sleep through the night for 12 hours at only 5 months old.
Georgia C.
Fits well & keeps him nice & warm
Tara L.
Nice sleep sack, did not help with sleep.
Chiazom O.
he is sleeping longer
Annette J.
I don’t know if it was a coincidence, but my 3 month old son fell asleep within 10 minutes of wearing it. First night he slept 6 hours straight. Big difference from waking up every two hours to eat every single night till now.
Albert A.
I have purchased before and they work wonders! Unfortunately the most recent one I bought has a defect to one of the arm holes and the placement of the zipper on the side.
Jennifer K.
The first night we put our 7 month old son in it he slept almost 8 hours!!! We put him down drowsy and he cried for about 10 mins and was out!! So impressed!! Thank you for giving me sleep back!!
Stephanie C.
Best thing ever
Gina L.
I love the nested bean sleep sack. My baby is 10 months old going through the sleep regression. Ever since I bought the nested bean sack baby have been sleeping better then ever. I still wakes up during night once or twice not as often as before.
Tiffaney B.
Helps my baby sleep so much better!!!! We love it
Amanda K.
She sleeps perfectly every night!
Dana L.
My daughter absolutely loves the sleep sacks we have been using them since she was newborn.
Emily S.
She’s a tummy sleepy so we love that we can reverse it so the weighted egg is on her back!
Dana S.
My 2 month old was waking up every 3 hours. On day 3 of using the sleep sac.. slept 5!!! hours. Baby had to be woken up to eat! Love it.
sakinah E.
My son is 4 months old I though it would help him sleep better but It didn’t work for him I haven’t seen a difference I do like that it is warm. I wish it worked for Him. I will keep having him sleep in it though maybe when he six months it may work. Thank you.
Alexis V.
It’s a nice transition for my baby from his swaddle. He loves it and it’s great it the weighted part could be on either back or front.
My baby loves to sleep on his back so this is perfect!
bridget h.
My son would not sleep at night unless he was being held. With his new nested bean weighted sleep sack, he not only sleeps without being held, he sleeps all night in his crib. I am very happy with our sleep sack!
Michaila C.
The box said 3 days, but within 2 our sweet girl was already sleeping better at night! Even her dolly loves nested bean!
Gladys C.
Just doesn't work for my LO...he flips over so much and the weight can't stop him from doing that. I wouldn't say he hates it, but he definitely doesn't love it.
Tiffany K.
Baby loves it! Highly recommended!
Jessica H.
I’m obsessed with the sleep sacks and my daughter went from sleep 45 minutes at a time to 10-12 hours at a time!!!! It took about a 5-7 days, but GAME CHANGER!!! Worth every penny!!!
Toni B.
We have been using this product for 9 months and it does help our baby sleep more soundly.
Natasha H.
It works but not all the time with my baby! Sometimes she wake up in middle of the night. But I will keep using it let see how it goes!!!
Camiele B.
My Baby is still pretty new, however the 2 nights I put the sleep sack on him he slept a little longer than usual. I believe it works
Kerra F.
Our 12 month old was waking up every 1.5-2 hours every night. I had read great things about nested bean and wanted to give it a try. By the third night he only woke up once and he's been getting the much needed sleep ever since!
Jessica L.
These are fantastic for our 10 month old. He was going through a sleep regression and just wanted to be held. These sleep sacks help him feel like we had a hand on him while he sleeps. Love them!
Christopher N.
My daughter was waking every 2 hours before I purchased this. After her late night feeding she now sleeps between 6-8 hours!
Kayla S.
Was a little worried about getting my 6 month old this huge sleep sack. He has just learned how to roll all over his crib and was driving me nuts at night. I realized he likes to sleep on his tummy but likes when I pat his butt or keep my hand on his back. I put this sleeper on him backwards so the weight is in his back and he calms down quickly to go to sleep. It’s awesome! Definitely took a few nights to get used it it but now he’s hooked and only wants to sleep in this! Guess I have to buy more lol
Lisa M.
Nested bean has the BEST customer service I’ve ever experienced. I was so happy with my purchase and I honestly can’t stress enough how these sleep sacs are life savers! Will never use another brand.
Brittany S.
Love it!
Danielle A.
Great transition option from swaddle!
In a few days my baby was already comfortable with his Zen Classic.
The material is very soft and the weight makes him feel cozy!
Kaci D.
On the side where the zipper is, it is ripped. Haven't had it for more than 2 months

Leslie S.
I bought the weighted sleep sac as a shower gift, as much for the parents-to-be as for the baby. Mom and Dad had never heard of them, but were delighted and excited to try it out.

My 4 month old loves this sleep sack! I recently transitioned him from the swaddle to and was very concerned about disrupting his sleep. He slept through the night from the first night I put this on him!
Rachel L.
Love it. Soft and launders like a dream. Dries in machine well too!

We went through two sleep transitions within a matter of days of each other. First, we had to stop swaddling as baby was showing signs of rolling over. Then, we had to move him out of his bassinet and into his crib as he was suddenly too big! After some awful, sleepless nights, I ordered the Nested Bean sleep sack and am so glad I did! We get a full 8 hours of uninterrupted sleep every night! I even catch our dog on the nursery camera going in to check on the baby after so many hours of sleep. :) Baby is 10 weeks now and we have been using the sleep sack for almost two weeks. Love it!

I don’t know if it was a coincidence, but my 3 month old son fell asleep within 10 minutes of wearing it. First night he slept 6 hours straight. Big difference from waking up every two hours to eat every single night till now.

I have purchased before and they work wonders! Unfortunately the most recent one I bought has a defect to one of the arm holes and the placement of the zipper on the side.

I love the nested bean sleep sack. My baby is 10 months old going through the sleep regression. Ever since I bought the nested bean sack baby have been sleeping better then ever. I still wakes up during night once or twice not as often as before.

My daughter absolutely loves the sleep sacks we have been using them since she was newborn.
Emily S.
She’s a tummy sleepy so we love that we can reverse it so the weighted egg is on her back!

My son is 4 months old I though it would help him sleep better but It didn’t work for him I haven’t seen a difference I do like that it is warm. I wish it worked for Him. I will keep having him sleep in it though maybe when he six months it may work. Thank you.

It’s a nice transition for my baby from his swaddle. He loves it and it’s great it the weighted part could be on either back or front.
My baby loves to sleep on his back so this is perfect!

My son would not sleep at night unless he was being held. With his new nested bean weighted sleep sack, he not only sleeps without being held, he sleeps all night in his crib. I am very happy with our sleep sack!
Michaila C.
The box said 3 days, but within 2 our sweet girl was already sleeping better at night! Even her dolly loves nested bean!
Gladys C.
Just doesn't work for my LO...he flips over so much and the weight can't stop him from doing that. I wouldn't say he hates it, but he definitely doesn't love it.
Tiffany K.
Baby loves it! Highly recommended!
Jessica H.
I’m obsessed with the sleep sacks and my daughter went from sleep 45 minutes at a time to 10-12 hours at a time!!!! It took about a 5-7 days, but GAME CHANGER!!! Worth every penny!!!
Toni B.
We have been using this product for 9 months and it does help our baby sleep more soundly.
Natasha H.
It works but not all the time with my baby! Sometimes she wake up in middle of the night. But I will keep using it let see how it goes!!!
Camiele B.
My Baby is still pretty new, however the 2 nights I put the sleep sack on him he slept a little longer than usual. I believe it works
Kerra F.
Our 12 month old was waking up every 1.5-2 hours every night. I had read great things about nested bean and wanted to give it a try. By the third night he only woke up once and he's been getting the much needed sleep ever since!
Jessica L.
These are fantastic for our 10 month old. He was going through a sleep regression and just wanted to be held. These sleep sacks help him feel like we had a hand on him while he sleeps. Love them!
Christopher N.
My daughter was waking every 2 hours before I purchased this. After her late night feeding she now sleeps between 6-8 hours!
Kayla S.
Was a little worried about getting my 6 month old this huge sleep sack. He has just learned how to roll all over his crib and was driving me nuts at night. I realized he likes to sleep on his tummy but likes when I pat his butt or keep my hand on his back. I put this sleeper on him backwards so the weight is in his back and he calms down quickly to go to sleep. It’s awesome! Definitely took a few nights to get used it it but now he’s hooked and only wants to sleep in this! Guess I have to buy more lol
Lisa M.
Nested bean has the BEST customer service I’ve ever experienced. I was so happy with my purchase and I honestly can’t stress enough how these sleep sacs are life savers! Will never use another brand.
Brittany S.
Love it!

Great transition option from swaddle!
In a few days my baby was already comfortable with his Zen Classic.
The material is very soft and the weight makes him feel cozy!

My baby LOVES her Nested Bean sleep sack. We have been getting an extra few hours of sleep a night ever since she started sleeping in it. She sleeps so soundly she bubbles :D
Leslie S.
I bought the weighted sleep sac as a shower gift, as much for the parents-to-be as for the baby. Mom and Dad had never heard of them, but were delighted and excited to try it out.

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.
