Love the product but I don’t think it helped my 4 month old to sleep longer.
Tamara G.
love it, super comfy to put on and warm without overheating
Melisa R.
Not as good as the swaddlers
Fitore D.
Does not do anything. You cannot return the item, waste of money.
Elle T.
So cozy, yet light weight and soft!
Kadee M.
Love the soft comforting material of this sleep sack!
Patricia D.
Like the product very much.
Samantha U.
We’ve used Nested Bean since our baby was born! I truly believe these sleep sacks have contributed to how well she sleeps
April D.
Love it , super soft and keeps my baby warm and sleeping good
Megan E.
This sack is perfect for my little girl. She has hip dysplasia and is in a rhino brace at night, and she fits perfectly in it with her brace on.
Lupita L.
I’ve used nested bean before on my son & now it’s my daughters turn & well I got this one because it’s becoming a bit hotter & she’d be unzipping and unbuttoning the sleep sack every time…idk lol but she’s pretty smart for a 16M old. So it’s become difficult for me to keep it on her
Sarah G.
My 14 month old used to wake up every 2-3 hours EVERY single night, but after trying the sleep sack for only 4 nights he is down to one wake up!! This sleep sack is a game changer!!
Rose Michelle G.
It’s a fine sleep sack. Lightweight material, soft, comfortable. The weighted part is just the little egg in the chest area. Overall good quality.
Amy A.
We used this for our first child and couldn’t wait to again with our second. The penguin design is so cute with the softest fabric, the perfect addition to our nested bean collection!
Alisha J.
We didn’t want a full weighted sleep sack because we live in a hotter climate and also were a little worried about the no weighted sleep sacks but the American association of pediatrics. This was the perfect compromise and I can tell our daughter loves it
Weatherford F.
My son sleeps so soundly in this! His other sleep sack has some weight to it, but only because it's warm, so I wanted something to use when it's warm outside or when we're washing his other sleep sack.
Didn’t receive this
Lisa M.
My baby absolutely sleeps 100x better with this sleep sacks. They are the perfect amount of weight for babies chest.
John K.
My little one started sleeping independently in her crib at 4 months and had problems staying asleep. The first night we used a nested bean swaddle sack, she slept through the night. She has been sleeping through the night perfect for 3 months and we have transitioned her to the luxe sleep sack, due to our climate. She loves it, so naturally we love it!
Deborah Q.
My daughter used Nested Bean with her son and now he will be having a sister - so more Nested Bean sleepers for her! Truly helps baby sleep soundly and safely!
Clarissa C.
Love the fit and helps him sleep. It’s great that we can put the weight on his back now that he likes to sleep on his stomach. The design is super cute and fun.
Alexis A.
I'm giving it 3 stars because I am sure this product has worked for other moms. The idea, look and feel of the product is great, but unfortunately it did not help our baby sleep any longer. It took a few days for him to get use to being in the actual sack and when we finally were able to lay him down in it he wouldn't sleep longer than 20 minutes.
Clarissa
Love the design and baby slept through the night comfortably
Karina
My daughter loves it
Tatiana
The best sleep sack ever! My baby girl loves it!
Ana

Egnatja
It really helped my baby sleep through the night,very breathable and cool material.
Anna

Leigh B.
These are so soft and easy to use. My granddaughter sleeps so much better and longer at night.
Jessica H.
My son won’t go to sleep until I put the sleep sack on him. With in 5 mins of putting him in this sleep sack he would fall asleep. We use it for naps and bedtime and he just loves it. It’s lightweight and he won’t over heat in the summer time.
Catherine S.
Love love love !! My daughter loved her swaddles straight out of the womb. We had to transition out of them when she started to roll and it has been a struggle ever since. Not anymore, she now has a sense of comfort when it comes to this sleep sack, so thank you !! She used to sleep 10-12 hours with a swaddle, maybe 5-6 hours without/ broken sleep and because of this amazing product, she now sleeps 10 hours, again!!! You’re a lifesaver !
Barbara P.
It doesn’t work to help with sleep, at least for my baby. Only good thing is it’s a blanket but the weight on the check doesn’t do anything for my baby. I still have to put my hand on her when she startles at night and she still wakes up every 1-2 hrs.
Patricia P.
The quality of the bamboo is great, and the snaps and zipper are very sturdy. I do wish there were more prints in the premier line. This sack keeps our boy cozy but not too hot with footie sleepers on.
I gave 3 stars because this sack did not improve quality or quantity of sleep. We used it consistently for a week, and there was very little difference between this sack and a regular cotton sack. I don’t regret the purchase because of the quality and how long I can use it, but I am disappointed we’re not getting any more sleep.
Erin
Nice and breathable. Wish we could afford 5 more!
Alli K.
My 3.5 month old was going through a sleep regression. It's been a couple weeks since he wasn't up every 2 hour. He only slept in his swing but was getting to big for it. The 1st night he slept from 9:30-7:00 fell back to sleep at 7:30 and slept until 11 all in his crib! Highly recommend for all. Love this item
Michelle E.
We need the lightest sleep sack there is in the summertime due to not having a/c. This one is perfect!
Adam
My child sleep is the most important thing in the world to my family. This has kept him sleeping and in a crib age 2. Love these!!!
Allissa T.
We used these sleep sacks for our first born and he loved them since he didn’t like having his arms swaddled down. Trying them out for our second was a no brainier. She loves them too and we can’t wait to keep using them
Tina Z.
Night two of using the sleep sack and it worked! I was so impresssed! Baby is sleeping so much better at night.
Priscilla W.
I’m very happy and our little one sleeps wonderfully
Meghan
Great lightweight material and my baby seems to like the light pressure over his chest.
Jessica G.
I purchased the zen one and zen swaddle on night while up with my 7 week old contemplating if I would ever sleep again! It was a great purchase and I wish I had done it much sooner! Baby enjoys both.
Shannon
Love the zen sack fabric and quality, but my baby will not get any use out of it until he starts rolling over and can wear the weighted part on his back. He is a tummy sleeper.
Jessica L.
I really like how light the fabric is (we went with the bamboo) but truthfully didn’t notice a difference in my sons sleep. The spandex sleep sacks we have work just as well, if not better. Nice to have for backup but wouldn’t use this as my primary option for bedtime.
Mariam H.
I always get the bambú since are my two new grandkids during the summer, best thing ever they are transition to this one without the swaddled arms, they both are sleeping all night . Great product.
Mariam H.
My grandkids love them!!!
Alicia
My daughter is 6 weeks old and she went from waking up every 3 hours to sleeping 10 hours a night! Such a lifesaver!
Rebecca R.
Still learning to like his sack but its definitely helping!!!
Kimberly J.
First night using this with my 5 month old, she was so calm, she fell asleep instantly without me rocking her. The fabric is light weight so it’s perfect for use during the hotter months. Not to mention the prints are super cute!
Rosa &.
I wish I could say this made a difference for sleep but it hasn’t. It is a lovely material but just a regular sleep sack for us, didn’t help with baby waking a lot through the night.
Michael F.
My son has acid reflux and he is so hard to get to calm down and go to sleep. Exhausted and desperate to find something to give us some sort of a break we come across your weighted zen sacks; the very first time we put him in it for a nap he fell asleep without much of a fight at all. I think it’s definitely a very good product to have!
Tina G.
My baby is a side sleeper. I switch putting the weighted part in the front and back and baby seems to like both. Highly recommended.
Rosmari L.
I love it! I used it on my first child and she slept so great that I bought it again for my second child.
Heather F.
Love it
Charidie T.
Overall a great sleep sack. It’s easy to wash and the fabric is soft and cool for hot summer nights. My only wish is that the shoulder straps were thinner because the have a tendency to fold in half due to chunky baby neck and cheeks. Also I don’t believe that it will still fit her at 6 months. For reference, my daughter is 3.5 months, 14-15 lbs, and 27.5 inches long.
Shahad J.
Material gets caught in babies legs because too thin and sheet like
Teri U.
We were really worried transitioning our baby girl from a full body swaddle to the arms free nested bean, because she slept so well swaddled up. As we approached the 3 month mark it was time to free her arms. The arms free nested bean works very well. To our surprise, our baby girl sleeps equally as well in the nested bean. I credit this to the weighted top in the design. We are very happy with this product and plan to buy more as she grows.
Kim C.
Fast Shipping, lightweight for new baby
Rosa M.
The day I got it my baby started sleeping more hours than usual. The bean area isn’t as heavy as I was afraid it was going to be, it was just the perfect amount. I would recommend this to anyone.
Amiee S.
I love these sleep sacks because our baby does! We’ve been using these since we transitioned from swaddling and our little girl has been the best sleeper! A dream come true for parents…we wouldn’t try anything different and are not sure what we’ll do when she grows out of the last sleep sack (15-24 months). Worth every penny, great quality!
Amber M.
My 4 month old loves his sleep sack! He sleeps so good with it. I bought this as a final thing to try because he absolutely would NOT sleep. First night using it and he loves it. He’s a tummy sleeper so he wears it backwards and as soon as we put it on him he instantly calms and puts himself to sleep. 10/10 would recommend !!
Mariam H.
Same as other
Megan U.
The material is so soft and I love that it's a tank top fit on top. It's great for the super hot weather. I havent noticed better sleep from our little one and it's been about a week but hopefully it's coming soon!
Katie H.
I really like it, it's nice to have him covered with something he can't kick into his face or off. The weight seems to help keep him down but as of sleeping longer I have not seen the results of that yet. The weight on the sleep sac seems to be a little higher then on the onesies. I purchased them as well and really like the onesies so far. Same results with the sleep, however. It's easier to put him down without waking up when putting him into his bassinette (which was a real BIG struggle for us) but the staying asleep he is still up every 1 -2 hours, but time will tell.
Nadine F.
Love this organic cotton sleep sack. Lightweight fabric and perfect for the summer season. The weighted bean no the chest gives just the right amount of comfort for your baby to sleep soundly. Highly recommended!
Heather C.
She loves it
Samantha D.
So far we have had this product for one week. I haven’t really seen the results, but will continue tkk on try.
Taylor C.
Sleeping through the night at 2.5 months!!! Love the feel and lightweight material!
Maki B.
LOVE this sleep sac! So incredibly soft and cozy - even my toddler tried it on and ran around in it, haha!
Kelly P.
Really beautiful material, very well made. Love the shape and the concept of the weighted chick on the chest, but we gave this a very fair try and it was just not what our 6month old needed. I’m sure it works spectacularly on other babies and is certainly worth a try in my opinion, especially for very desperate parents. Just be ready for it to *not* be the answer, just in case
Dominique F.
Just didn’t notice any difference. Except she can’t get up and go on her own
Kristy L.
Love it like everything else I’ve gotten from them!

Laura T.
She has been sleeping through the night!
Kati L.
Before I got the nested bean sack my baby would wake up every time I put him in his own crib. He would be fast asleep but as soon as I laid him down in his eyes would pop right open. I decided to buy the nested being sleep sack After I did extensive research regarding all of the options.
I am so happy that I purchased the sack. I’m able to sleep with my husband by ourselves to get the quality time we need. My baby loves it and looks forward to sleeping in each night. Thank you nested bean sack you are the best!
Buy this sack! You won’t be disappointed
Ana C.
Baby stays asleep longer. Will wake up but feel the weight and fall back asleep. Definitely recommend
Kayla H.
We consistently put our baby in the Zen Sack at night to sleep & she now sleeps 8-10 hours every night. We started her in it at 2 months & she’s now almost 3 months. Best sleep sack out there!!!
Cortney S.
I absolutely love this. He sleeps so well. He wakes up once and goes right back to sleep. He’s 5 months. I highly recommend this product, and have already recommended it to my mommy friends!!!
Hayleah H.
We love this option for a lighter material since we live in Texas. Our LO sleeps so well in these.
Jennifer H.
Really soft, beautiful quality. Don’t think I see a change in her sleep. But we are also in the 4month sleep regression timeframe.

Mac K.
Great !
Kelly A.
I love this premier bamboo fabric for summer. We live in California and it’s warm, but I still like having a sack on her, so this is perfect. The medium size fits my 6 month old great.
I just wish it came in plain colors like the original weight does.
Christopher O.
We bought this for my daughter in lieu of a transition sack around the 7 week mark and my daughter loved it. The weight was heavy enough to prevent her startle reflex from waking her up, but it’s not heavy enough to hurt her. She’s been sleeping 5-7 hours for about 2 weeks now.
Victor F.
Great product. Helps my baby to get a better sleep, definitely a game changer.
Jennie E.
The sleep sack is cute and well made. I ordered bec I'm desperate for some sleep. After reading a bunch of reviews I finally caved. Maybe my baby is defective, bec she still doesn't sleep. Lol. So no magic beans for us and I'm still one very tired Mama.
So now she has a nice $50 dollar blanket.
Kristy O.
My DIL says my grandson has slept great in this Zen Sak Premier (bamboo material) for last couple nights! He loves it!! Will be ordering more for sure!! Has the cotton ones as well but loves the bamboo ones even more!!
Lorena S.
Such a comfy and cute sleeping sack. Very soft and very easy to put on. The weighted part is so nice to be able to use both on baby’s chest and even back. Always been a huge fan of this brand!!
Huda G.
Daughter is 4months old and wakes every two hours. I purchased the Nest sack and still see no difference after a week. I’m hoping that will change down the road but for now, this is my review. Every baby is different, mine is not favoring this yet. The quality is great though.
Julia F.
Soft, lightweight and perfect for warmer climate. Baby loves the extra weight on chest too.
Ashley W.
I absolutely love these! My sons sleep DRAMATICALLY improved while wearing these sleep sacks! I wish I got them sooner!!!!
Karissa T.
My little guy loves his ! Puts him to sleep so fast ❤️
Amanda I.
Recently switched to the Zen sack because we outgrew the Zen One. We have been using the nested bean products since 2 months old. They help my like guy sleep more restful. Plus, he looks so cute.
Ebony F.
Thought this product would be an answer to my prayers for my baby to sleep through the night. I would say I like the concept and the diaper changing zipper.
Jessica M.
Changed my daughter's sleep in 4 nights! She loves feeling snuggled by the weighted bean on the chest.
Amy B.
My little one loves the nested bean zen sacks! We recently got the "premier" one for the upcoming hot summertime and so far it has been perfect and lightweight.
Patricia L.
My LO loves his sleep sack and gets excited about putting it on . Once he’s down he feels relaxed and sleeps throughout the night.
Celeste M.
My LO was used to being swaddled since birth. She disliked her hands being put inside the swaddle. We got to a point where we could no longer swaddle because she was really tall and her legs couldn't be wrapped. I read many reviews about the NESTED BEAN and decided I would give it a try. I am so glad I did, it really works. My LO sleeps very well through the night and her hands don't have to be put inside a swaddle.

I’m sure it works spectacularly on other babies and is certainly worth a try in my opinion, especially for very desperate parents. Just be ready for it to *not* be the answer, just in case

Just didn’t notice any difference. Except she can’t get up and go on her own

Before I got the nested bean sack my baby would wake up every time I put him in his own crib. He would be fast asleep but as soon as I laid him down in his eyes would pop right open. I decided to buy the nested being sleep sack After I did extensive research regarding all of the options.
I am so happy that I purchased the sack. I’m able to sleep with my husband by ourselves to get the quality time we need. My baby loves it and looks forward to sleeping in each night. Thank you nested bean sack you are the best!
Buy this sack! You won’t be disappointed

We consistently put our baby in the Zen Sack at night to sleep & she now sleeps 8-10 hours every night. We started her in it at 2 months & she’s now almost 3 months. Best sleep sack out there!!!
Cortney S.
I absolutely love this. He sleeps so well. He wakes up once and goes right back to sleep. He’s 5 months. I highly recommend this product, and have already recommended it to my mommy friends!!!
Hayleah H.
We love this option for a lighter material since we live in Texas. Our LO sleeps so well in these.
Jennifer H.
Really soft, beautiful quality. Don’t think I see a change in her sleep. But we are also in the 4month sleep regression timeframe.

I love this premier bamboo fabric for summer. We live in California and it’s warm, but I still like having a sack on her, so this is perfect. The medium size fits my 6 month old great.
I just wish it came in plain colors like the original weight does.

We bought this for my daughter in lieu of a transition sack around the 7 week mark and my daughter loved it. The weight was heavy enough to prevent her startle reflex from waking her up, but it’s not heavy enough to hurt her. She’s been sleeping 5-7 hours for about 2 weeks now.
Victor F.
Great product. Helps my baby to get a better sleep, definitely a game changer.
Jennie E.
The sleep sack is cute and well made. I ordered bec I'm desperate for some sleep. After reading a bunch of reviews I finally caved. Maybe my baby is defective, bec she still doesn't sleep. Lol. So no magic beans for us and I'm still one very tired Mama.
So now she has a nice $50 dollar blanket.

My DIL says my grandson has slept great in this Zen Sak Premier (bamboo material) for last couple nights! He loves it!! Will be ordering more for sure!! Has the cotton ones as well but loves the bamboo ones even more!!
Lorena S.
Such a comfy and cute sleeping sack. Very soft and very easy to put on. The weighted part is so nice to be able to use both on baby’s chest and even back. Always been a huge fan of this brand!!

Daughter is 4months old and wakes every two hours. I purchased the Nest sack and still see no difference after a week. I’m hoping that will change down the road but for now, this is my review. Every baby is different, mine is not favoring this yet. The quality is great though.
Julia F.
Soft, lightweight and perfect for warmer climate. Baby loves the extra weight on chest too.
Ashley W.

Recently switched to the Zen sack because we outgrew the Zen One. We have been using the nested bean products since 2 months old. They help my like guy sleep more restful. Plus, he looks so cute.
Ebony F.
Thought this product would be an answer to my prayers for my baby to sleep through the night. I would say I like the concept and the diaper changing zipper.
Jessica M.
Changed my daughter's sleep in 4 nights! She loves feeling snuggled by the weighted bean on the chest.
Amy B.
My little one loves the nested bean zen sacks! We recently got the "premier" one for the upcoming hot summertime and so far it has been perfect and lightweight.
Patricia L.
My LO loves his sleep sack and gets excited about putting it on . Once he’s down he feels relaxed and sleeps throughout the night.
Celeste M.
My LO was used to being swaddled since birth. She disliked her hands being put inside the swaddle. We got to a point where we could no longer swaddle because she was really tall and her legs couldn't be wrapped. I read many reviews about the NESTED BEAN and decided I would give it a try. I am so glad I did, it really works. My LO sleeps very well through the night and her hands don't have to be put inside a swaddle.
