We’ve been using the sleep sacks for just over three weeks now. Originally I bought two and have just placed an order for two more. Our girl never liked the swaddle and wouldn’t sleep if she couldn’t have both hands free. Our pediatrician steered us away from fully weighted sacks. I found the nested bean from an add on Facebook and have loved every second since. It definitely took a few days for her to adjust but we went from one to two night wakings to sleeping through the night at three months old.

These have been an interesting mix in our sleep sack experience with our daughter. She likes them most of the time, however, she is a roller so sometimes when the egg is on the side she laying on (mattress side) it seems uncomfortable because it's like a lump. Wish I would have gotten the larger size that has it all spread out, I think it would have been a better solution for her. She is 6 months old for reference.

We loved our nested bean sleep sack! This helped our little guy sleep hours longer!
Dasia K.
I was super excited to try the Zen sleep sack. I purchased the 6-15 month shortly before my son turned 4 months. However, he has not been sleeping better. I had such high hopes but he is still waking up every 2-3 hours at night. I do like the zipper for diaper changes at night but not sure that feature alone is worth the money.
Katie K.
We love our zen sleep sacks. Our baby sleeps all night when he wears it.

I like this baby sleeper. Yet, as the picture shows. I bought two 6-15 month sleep sacks, they all came with medium packages but the the actual size look so different
Vanessa Y.
My daughter loves this Bean. She is constantly rubbing the center of it to soothe herself to sleep so we don't have to do it as often. Been using it since 4 months old.
Nyki P.
My order was sent back due to an error I tried to contact the support team and didn’t get a response. What are the odds it could be resent with the correct information. 639470 Was my order number

We ordered these for our 6 week old who fights sleep. They are very high quality, wash and dry very well, and are easy to use with great 2-way zipper and adjustable shoulder snaps. I cannot say that it helps her fall asleep better, but it does help her stay asleep. She seems to like them.
Kael C.
Love this product!! I bought them for my 6 month old during a sleep regression and it has worked wonders. We are finally getting sleep again after waking up every hour and a half to two hours
Carly H.
My baby was not sleeping through the night. She would punch and kick and wake herself up all throughout the night. After sleeping with the sleep sack, we put her down at 9pm, and she wakes up at 5am. Best investment EVER!
Melanie G.
This was purchased for my granddaughter, who sleeps better than a baby now with these sacks!!
Adrianne A.
The secret to my son sleeping through the night! Without the sleep sack he would wake up every few hours but with the sack he will sleep through up to 8 hours! Will never go without it
Kayla A.
My son loves these!! He was waking up at least 3 times a night and now, I put his sleep sack on backwards since he likes to sleep on his tummy and he sleeps through the night every night! ❤️
Rachel H.
My son is 3 months and it has worked wonders! I've been getting 5-8 hours of sleep every night!
Alison S.
I think the concept is cool and as a first time mom i was anxious about transitioning my LO to a sleep sack. I found after 2 weeks of use, LO preferred not to wear the weighted sleep sack as he was getting more mobile and the weighted egg was annoying/confusing him.
Cecilia S.
I got these for my 2 month old to use at his daycare where they aren’t allowed to be swaddled. My baby adjusted well and fast. He didn’t like being swaddled after his 1st month. These were a great alternative.
Meghan R.
My newborn has really liked this sleep sack. She hates her arms swaddled. This sleep sack is awesome for diaper changes too!
Kelsey K.
At first I thought it was not working at all. The first night with it on she slept worse than ever. As the week went on though, she slept longer and longer stretches and much deeper. She still wont sleep unless I’m next to her but I can actually get up to go to the bathroom now without her waking up immediately. I also have been having to pump in the night now because she’s sleeping so much longer and not waking up to eat as much!
Jenny S.
Not sure if baby was just extra tired, but the first night we used this, he slept 6 hours straight!!! I have used it every night since then and he sleeps up to 8 hours each time! Definitely worth the money!
Danielle C.
I’ve been using the nested bean weighted sleep sack since my son was too big for a swaddle. He loves it! He grew out of his first one and I ordered the next style of his age and it’s been working just as well. I love the snaps on the shoulder to take it on/off easily. I wouldn’t use a different brand ❤️
Wright S.
The quality of the sleep sacks is awesome, but they don’t help my daughter sleep at all, unfortunately.
Kat B.
They’re soft, a good weight and material, and have good features. Can’t say they’ve had any effect on our twins’ sleep.
Allison T.
We love the product! We unfortunately received one of our sacks with a stain and didn’t have the time with a newborn to return and request another.
Trena M.
We love our little sleep sacks!! We have a set of twin granddaughters and this has been a life savor!!
Jamela P.
This worked so well my grandbaby slept for 8 hours .
Luke H.
Works perfect, 5 month old sleeps longer at night and into the morning
Mom K.
It’s somewhat helpful. I think we are also going through a sleep regression. So I can’t say 100%
Kathryn S.
This is a great product!! It's light so it doesn't overheat him. He can sleep through the night now. Thank you!!
Katie C.
We are on night 4 and I have to say they are working! We get around 4 hours of sleep at a time compared to every 2 hours he was up. I do recommend them to anyone.
Sarah B.
I had originally bought these to help my LO sleep longer.
He still does not sleep longer but these help him calm down.
My LO doesn’t seem to nap during the day, and is cranky and overstimulated at night. Resulting in a very upset baby. These sacks have helped tremendously!!! I would recommend
Christine F.
Its very soft, very easy to get on and off, even one handed while she's ready to nurse and snuggle!
I'm not sure if it makes a difference with how long she sleeps - she's a tricky one anyway, but it's a comfy sleep sack either way, and stays in place well through the night.
Julia C.
I really like that I was able to purchase two as a set. I loveeee how much space it gives my son. He's five months and definitely grew out of the other weighted sleep sack we had that was newborn to 6mo size. I switched to this brand for its price point, and I like that the whole sack isn't weighted but just the egg. Love the options for gender neutral styles for boys and future babies that may come later on or to pass down to friends.
Danielle W.
Life saver since the big 4 month sleep regression. There hasn’t been a night we haven’t used it in over a month!
Tiffany B.
Amazing! Made my son’s transition into his crib seamless!
