What is The Cuddle Effect™?
Medical experts agree: it’s not just the swaddling, the rocking, the lullabies that soothe your baby to sleep. It’s your touch. And it’s vital to your baby’s well-being. Recent scientific 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. That means longer, sweeter sleep—until they’re back in your arms.
-
Which size is best for my baby?
For the product you are considering check its size chart. Your baby should not be below the minimum weight and should have at least 2-3 inches to grow before growing past the maximum height.
-
What’s the difference between Classic, Premier, and Winter products?
The Classic line is perfect for year-round use! The fabric is 100% cotton.
The Premier line is more lightweight and breathable than the Classic line, making it perfect for warmer climates or babies who overheat easily! The fabric is a blend of 70% bamboo + 30% cotton.
The Winter line is the warmest option, perfect for cooler climates or A/C in the summer! The fabric has two layers of 100% cotton with a heavy poly-fiber filling in between.
-
Is the Zen Sack™ safe for babies who roll over?
The Zen Sack is perfectly safe for babies who roll during sleep! The weight is light and flexible, so it will nearly flatten underneath your baby's body. For tummy sleepers - who can roll completely independently - the Zen Sack can be worn backwards!
-
How much weight is in each product?
Physiotherapy standards were used to determine the appropriate weight in the Zen Sleepwear. These weight requirements ensure that the weight to body-weight ratio is maintained well below the recommended Physiotherapy standard of 1:10. Depending on the size of the product, the weighted parts range from 1 to 5 ounces.

My daughter loves her sleep sack! Not only does she sleep longer, she now identifies her sack with sleeping time and starts self soothing as soon as we put her in it. Couldn't love this product more. Wish I had known about it when my older kids were babies.
Amanda D.
I got this for my granddaughter. Her Mom will not let her have a blanket for fear that she will strangle herself. So this is the perfect solution. My daughter loves it. My granddaughter will arrive in October.
patricia p.
Love it
Kasie B.
Our son would not sleep in his crib after the bassinet transition. Once we got these sleep sack he now sleeps all through the night with no issue. We love it!!
Melissa T.
My son loves this sleep sack. He's a NICU baby and is used to being swaddled so now that he's a bit older he's not needing as tight as a swaddle and the weight on his chest is perfect to help him fall asleep.
Danica Kristl D.
Helps my LO sleep longer. Will definitely purchase another one. I just wish that it is longer. My LO is kind of average height and on the light side and I feel like he’s already outgrowing the medium.
Julia S.
My son loves the sack and sleeps so well and through the night
Misti S.
My son has worn it 6 times and slept through the night once not sure if it's working for us.
Veronica T.
I started using the nested bean sack when my daughter was 3 months old.. it helped her sleep through the night! I decided to use a regular sleep sack when I noticed her sleep pattern was consistent as grew out of the bean. Then the 10 month regression hit.. I knew that I needed to buy it again in her size. It worked almost instantly! I can’t thank the Nested Bean enough for creating such magic! I can finally sleep again!!
Erin H.
This hasn’t worked that well for us. Haven’t seen much of a change with the sleep of our 3 mo. old.
Gabriela G.
I was super excited to try this product in hopes it would help my little one sleep better. There was no change in sleep. I tried having my little one wear it for bedtime and nap times. It is super soft and easy to put on and take off. He continues to use it for comfort but no change in sleep.
Courtney T.
I was honestly skeptical. There are so many products that promise results and don’t deliver, but this one is LEGIT! I had so much trouble putting my little one down to sleep, but now when it’s bedtime I literally feed him, change him, and put him in the bag. He does a little shuffle and falls right asleep! He also is able to soothe himself when he wakes up without me helping him, which is something I’ve never experienced with any of my kids! I can’t recommend this product enough!
Olivia W.
My daughter loves it!
Jacqueline O.
Great!
Melissa H.
My son is staying asleep longer.
Morgan S.
Hasn't made any difference to my child's sleep unfortunately
Is a good quality sleeping bag though. But cost me a lot to ship overseas.
Will keep trying to see if it makes any difference
Rachel S.
Love this one because it has weighted beads spread out all over the chest piece instead of just the center circle in the previous size(6_12 months)...it works better for my LO since she's a tummy sleeper.
Gisselle G.
I love the zack since I bought this my daughter sleep straight between 6-7 hours so happy about it.
Thank
Lynelle M.
I need another will order soon
Samuel H.
We've had it for about a month now, we use it every night for our 11 month old, she was waking up about 3 to 4 times a night maybe less, the past couple of weeks, she'll wake up 1 or 2 times a night now, so I guess it's working some what.
Ilse M.
When we first bought it we thought it would be your “average” sleeping sack but he slept through the night the first day we got it!! I haven’t slept a full 7+ hours since he was born (he’s almost 10 months) and now I get to have my sleep back!! I trust Nested Bean with my SLEEP lol I’m always recommending it to my mommy friends as well.

We had the smaller size but as my daughter got bigger we have to get the bigger size. We love it!! And she seems to love it also. The customer service is AMAZING!
Alondra B.
Love this sleep sack! Best thing to happen to us as first time parents little one sleeps so comfy and helps prevent her getting stuck in between crib bars!
Trinh N.
It didn’t work for our 5 months baby. She still wake up every 3 hours for feeding. I was really hoping it would help because we had tried so many different brand.
Dean D.
Weighted sleep sack doesn't seem to help my baby get to sleep any quicker or stay asleep any longer. In hindsight, I wish I would've bought twice as many normal sleep sacks to have more in rotation while others are being washed. Hopefully this helps other babies, but I don't feel the added cost was worth it for mine.
Nadia P.
Nothing works better for our son!
Will only sleep in his crib with his on!
Christina O.
I recommend Nested Bean to all of my new mama friends. My son sleeps really well in all three sizes he's grown out of and into.
Destiny R.
My little one loves it! He pretty much is sleeping thru the night.
Miranda W.
Our little one still has trouble sleeping. We’ve tried almost everything we know but they keep waking up multiple times nightly. We do feel the the zen sack has helped reduce the number of awake times though it’s still a nightly battle.
Resena H.
My little one likes her sleep sac, the only con is she gets warm throughout the night and then wants it off.
Christina T.
It's okay for the blanket but that's about it. My baby can't use the swaddler anymore b/c he's rolling over, so the reviews led me to buy this product. The bean pad doesn't make a difference for his sleep but at least he's warm! B/c he's so young, he still has the startle reflex really bad, so maybe when he's older this sleep sack may fulfill it's purpose
Michelle B.
Bought for my grandson his parents love it
Audrey B.
My two month old isn’t sleeping through the night but is definitely sleeping better with the sleep sac. Love it so much!
Ashley G.
Like all exhausted parents I was hoping for a miracle. I get some decent naps in but nights are still very hard with frequent wake ups. I think it’s good for what it is for sure but if you have a tough sleeper don’t put all your eggs in one basket.
Travis C.
Great sack. Really helps keep our son comfortable during his nightly snooze.
Linda L.
Helps grandson sleep during the night. Have used two sizes now as he grows!
Stefanie B.
I was amazed when I first out this on. Not sure what took me so long to try it but within 30 seconds she stopped crying and was out. I went online so fast and bought 3 more and a swaddle for nighttime!! Obsessed with how great these work! Pure magic!
Kimberly P.
Quality is nice. I love the double zipper to ease night time diaper changes. I’m not sure that it has helped my baby sleep better after a month. He still wakes 1-2 times at 4.5 months of age. Overall I don’t regret the purchase cause anything is worth a try and I wanted another sleep sack to rotate anyway.
Rashmi J.
We got the sleep swaddle and the sleep sack for our baby and she loved both! She sleeps comfortably for hours in both :)
Alexis D.
Loves his nested bean sack! I'm no longer spending hours with my hand on his chest and he's sleeping in longer stretches after only a few days
Heather S.
I bought this for my 2 month old who was waking every 2-3 hours during the night. When we use our nested bean he will typically only wake once around 3am. We've even had a couple nights where he has slept from around 10:30pm to about 7 am without waking!
Staci F.
It’s an ok sleep sack. I wouldn’t say it’s a miracle worker though. It didn’t really help my son sleep a lot better. Maybe a little though. But the biggest disappointment was I got the 0-6 months bc my son is only 14lbs and it says it’s for height up to 30 in but my son is 26 inches and it’s basically too small already. Also I wouldn’t say it’s for year round, it’s pretty thin. He feels cold when he wakes up and he has fleece footed pajamas on underneath.
Olga T.
This product is very soft and the two way zipper is useful. Nevertheless, I did not find it super effective for sleep improvement, as advertised. It is just a sleep sack, therefore considering the price, would not recommend purchasing one.
Jamie C.
A week after using the sleep sack, my three month old sleeps at least eight hours every night. This is an absolute miracle product!!
Taylor Z.
Exactly what I hoped for, baby loves it, and he'll be able to grow in it! Great color, and weighted perfectly. I'm beyond happy
Thara W.
Baby loves it. Great quality material. Will be ordering more.
Danielle G.
My son went from waking up constantly through the night, to sleeping most, if not all the way through, the night! It was such an amazing difference for both of us. This momma was finally able to get some good sleep!
Sandra S.
I ordered this for my almost 6mo who was showing signs of getting ready to roll over. The first night we put him in it... Of course he rolls! I'm glad I had him in this and vs. his transition swaddle.
I'm loving how easy it is to put it on and take it off. Night time diaper changes are easy because of the way shower. I love the material and the weighted egg. I also like that it is sleeveless so we can dress him up or down as needed!
Katren T.
Wonderful product! Perfect for summertime my baby lobes it and it straps on top make it easy to remove.
Caroline T.
My baby has been a pretty tough sleeper since birth and at 3 months I was reaching the end of my rope with night wakings every 2 hours. I used some different sleep methods which helped some and then the Zen sleep sack really helped! Now we get 5 hour stretches of sleep- huge improvement! We will be buying another!
Brittany Y.
Not only did it help my baby to start sleeping through the night but as soon as I put it on my son he instantly knows it's time to sleep.
Jordan R.
We LOVE the nested bean sleep sacs. I used them with my first baby and they made a world of difference. He would sleep through the night with it on. It is a great sleep sack and worth the money.
Allissa T.
Our baby loves this sleep sack! He never let us swaddle his arms down but having the weighted egg helps him still feel comfortable. I just ordered the next size up as well as a premium for the warmer days
Leslie B.
This is our second sleep sack, he grew out of the first one. Definitely a life saver, he sleeps 7-11 hours a night Beware of the navy though, fuzzies come off on everything.
Taylor V.
Nice quality sleep sack and we do like it. Unfortunately however there has been no improvement in our 8 months old sleep. He is still up every few hours. We’re continuing to use it and are optimistic it will soon start to make a difference. We’ve been using it a few weeks so far. Fingers crossed for fewer sleepless nights in future!
Shibali N.
Absolutely love love love these well made amazingly soft and safe sleeping bags! Two way zippers help changing baby's diaper without taking the whole bag off an absolute breeze! Adjustable shoulder tabs and reversible bag so the bean egg is on her back for my 9month old tummy sleeper! Got 3 colors and all of them are absolutely gorgeous- Sand, Night sky and Lemon!

We love our nested bean! I was so nervous transitioning out of the swaddle, but the sleep sacks made it so much easier. Our son has been sleeping through the night since 2.5 months and we nurse our sleep sack every single night :)
Ashley V.
Works great!
kirsti d.
We love it!
Caitlin D.
Absolutely love Nested Bean, just bought the next size up as my daughter grows and she loves it! She can move around but can't climb out of her crib, and the weighted portion of this size is larger and works both on her back and chest!
Mycah S.
She loves it! We have been using it every night and she sleeps so well. So glad we made the purchase
Patricia Y.
We love the sleep sack. It helps her stay warm and sleep tight.
Karen M.
We are still getting use to it my baby is finally sleeping in her crib instead of on us. But I guess because she’s almost a month old and we are breastfeeding so we wake up on her demand on food.
Noemi C.
Best baby purchase!
Monica W.
I absolutely love this sleep sack! Nested Bean has continuously made our baby sleep much better at night while remaining safe!

Lindsay M.
Our babe has been a pretty great sleeper since the beginning! But I was nervous about transitioning from an arms contained swaddle to an arms free sleep sack. Nested bean made the transition easy! At 2 months we started putting the classic nested bean sleep sack on our son during naps and eventually when he started to show signs of rolling, we paired the sleep sack with his nighttime jammies and had no issue at all! Since we was 3 months old he has been sleeping through the night! We swear by this product!
Allyson S.
The first night my daughter seemed very uncomfortable in it(I expected her needing to adjust to it), the second night she slept 7 hours straight(prior she was only sleeping 3/4). Since then she has slept Atleast a 6 hour stretch!
John S.
Got theses for my daughter’s first baby she loves them.
Sarah L.
Not an ideal swaddle transition. The sleep sack didn’t provide a smooth swaddle transition. We ended up having to switch to the Merlins Magic Sleep Suit. The startle reflex and wild arms are too much for this sleep sack. We will try again when he is a bit older.
Michela N.
The absolute best! Since the first night I used this product my baby has slept better and longer through the night.
Lyn
My twins are sleeping wonderful! Great purchase have had a sound nights sleep since we began using this product!
Brittani P.
My baby girl loves this sleep sack! Before finding the nested bean zen sleep sack, she loved for us to lay our hand on her chest while she fell asleep. This gives her that same comfort! She falls asleep very quickly and stays asleep throughout the whole night. Highly recommend!
Jessica G.
My 2 and half months baby it’s falling asleep at 9pm, sometimes at 10pm, he wakes up at 3am to eat and then fall sleep again until 7am since we started using the zen sack! He was used to wake up 3 times at night! I really appreciate the rest!
Tanía R.
I initially purchased this sleep sack because my 8 month old is a terrible sleeper. She's a BF baby so she's constantly waking up for feedings. I put the sleep sack on her and the first night she slept for 4 hours straight. However I've been noticing her awaking more often and it's be she gets super hot. I put her in the sack with just a pamper and she's still sweating pretty bad throughout the night. My only complaint is that I wish the day had a lighter material or it was ventilated because I do feel it works. I keep trying it nightly but then I have to ultimately take her out of it because she over heats.
Mary G.
The weighted sleep sack is really nice! It hasn't magically made my 4 month old shell through the night, but he likes it and it's excellent quality. Honestly, I would buy more sacks even without the weight because of the quality. Soft cotton, a double zipper so can unzip from the top or bottom, the zipper is enclosed in more soft fabric, the straps have two snaps so you can expand as baby grows, it has snaps at all so you don't have to wrestle sleepy little arms through holes ... Overall I love it. It didn't fulfill my hopes of instant sleeping more than 2 hours at a time, but that's okay, I didn't expect it to be a magical solution. Its quality alone is worth buying.
miroslava L.
It is a good sleep sack but the weighted part does not make a difference.
Ryan W.
My little babe has such trouble sleeping, with the sleep sack we are all able to get more zzzz
Martina D.
The sleep sack is lovely. Unfortunately, after two nights the zipper seam started to come undone, so the zipper is pulling away from the material.
Olga U.
I like material, but go our house where temperature is 72-73F at night it’s cold for my baby (it says that it’s all year) so I have to order winter option , and it’s perfect
Amanda M.
Super cute! My little babe sleeps well in this. She was in the zipadeezip prior but their sizing is off a little bit. She needed a regular sleep sac anyway and access to her hands. She is a side/belly sleeper and every once in a while she will sleep on her back, but the beads don’t bother her. Will continue using the zen sleep sac.
Grace T.
Cute design and very well constructed. Super soft even after washing and the little chick on front makes me smile. Love that the zipper goes all the way around. The only issue is that it can be a little awkward to snap on the shoulders when the little guy is rolling around.
We’re not sure if the little weighted chick is what did it (or that baby is 7 months now) but he has been sleeping longer since we switched to this sleep sack for overnight.
Briar S.
My daughter sleeps so great and loves her sleep sack!
jessica l.
Love it!
Grace F.
We’ve had our sleep sack for a few weeks and unfortunately I haven’t noticed a difference at all. At 4 months, still up 2-3 times a night. I will say that he does go back down after feeding easily so that is something! I’m hoping that he starts sleeping through soon. I’ve been back at work for a few weeks and mama is tired!
Ashley F.
My son loves his sleep sac! He immediately calms down and has been giving me 7 hour stretches of sleep at 10 weeks old!
Kim S.
We love the nested bean sleep sac, our little one is a tummy sleeper and we put it on her backwards, it works perfectly!
Alexandria M.
It took a few nights for my baby to get use to her arms out… I really wanted to give up and continue to swaddle but she was able to get out of her swaddle so it was becoming dangerous and that in itself made me anxious and was not worth a good night of rest for me. I feel like it’s safe and she is use to it and getting a good nights rest. It’s easy enough to change her diaper in the middle of the night and not disturb her after nursing. Actually less disruption than the swaddle. I’m happy so the purchase
Alma B.
Love it must have the material is so soft my baby sleeps so good in this definitely perfect for this summer heat
Randalyn B.
Love the sleep sack. Previously had the
Diana G.
This didn’t work with my baby. I’ve tried both the classic and the winter zen sacks, and have been using them for over a month and my baby’s sleep has not changed one bit. The night wakings continue in the exact same way. Also the size seems a bit small. I got the 6-15 months old size, my baby is 7 months old and it seems he’ll outgrow them in a couple of months.
Magdalena M.
My son sleeps better in a fill swaddle at the moment due to his startle reflex, but I believe he will like it when we start taking his arms out
Amirah R.
Since transitioning my son into his room he been using these and so far so good! Not sure if it was sleep training or these sleepsack but he sleeps for about 11 hours !
Stephenie B.
Nested bean has helped our little bean sleep better all around! It’s lightweight, soft, & comfy. The weight is centered in the chest area and is just enough to comfort our baby to keep him asleep a little longer.
Robyn S.
The nested bean is a nice sleep sack. I like the ease of the zipper and snaps to put baby in the sack. However, I am disappointed that I did not see any improvement in my baby’s sleep.
Carly M.
My 4-month-old was an exceptionally good sleeper (going 5-7 hour stretches when he was still only 1 month old), but he was having trouble transitioning out of his swaddle, so we thought we would try the Zen sack. Unfortunately, it has not been going well. He now wakes up every 2 1/2-3 hours at night and he sleeps pretty fitfully for hours in the middle of the night. I am giving this a 3-star review because (1) he does fall asleep faster with it on, even though it doesn't seem to make any difference in how long he stays asleep; (2) he really loved being swaddled, so maybe he is just still missing that (although it's been about 3 weeks now since we last swaddled him) and (3) he's pulling his legs up a lot, so it's possible the new sleep difficulties are gas-related and have nothing to do with the Zen sack. But whatever the reason, our sleep schedule has taken a very unfortunate downturn.
Ashley H.
I use this plus the 8 sheep lotion and it works wonders!He's more on a steady schedule now and sleeps through the night

I haven’t slept a full 7+ hours since he was born (he’s almost 10 months) and now I get to have my sleep back!! I trust Nested Bean with my SLEEP lol I’m always recommending it to my mommy friends as well.

We had the smaller size but as my daughter got bigger we have to get the bigger size. We love it!! And she seems to love it also. The customer service is AMAZING!
Alondra B.
Love this sleep sack! Best thing to happen to us as first time parents little one sleeps so comfy and helps prevent her getting stuck in between crib bars!
Trinh N.
It didn’t work for our 5 months baby. She still wake up every 3 hours for feeding. I was really hoping it would help because we had tried so many different brand.

Weighted sleep sack doesn't seem to help my baby get to sleep any quicker or stay asleep any longer. In hindsight, I wish I would've bought twice as many normal sleep sacks to have more in rotation while others are being washed. Hopefully this helps other babies, but I don't feel the added cost was worth it for mine.

Nothing works better for our son!
Will only sleep in his crib with his on!
Christina O.
I recommend Nested Bean to all of my new mama friends. My son sleeps really well in all three sizes he's grown out of and into.
Destiny R.
My little one loves it! He pretty much is sleeping thru the night.
Miranda W.
Our little one still has trouble sleeping. We’ve tried almost everything we know but they keep waking up multiple times nightly. We do feel the the zen sack has helped reduce the number of awake times though it’s still a nightly battle.
Resena H.
My little one likes her sleep sac, the only con is she gets warm throughout the night and then wants it off.
Christina T.
It's okay for the blanket but that's about it. My baby can't use the swaddler anymore b/c he's rolling over, so the reviews led me to buy this product. The bean pad doesn't make a difference for his sleep but at least he's warm! B/c he's so young, he still has the startle reflex really bad, so maybe when he's older this sleep sack may fulfill it's purpose
Michelle B.
Bought for my grandson his parents love it
Audrey B.
My two month old isn’t sleeping through the night but is definitely sleeping better with the sleep sac. Love it so much!
Ashley G.
Like all exhausted parents I was hoping for a miracle. I get some decent naps in but nights are still very hard with frequent wake ups. I think it’s good for what it is for sure but if you have a tough sleeper don’t put all your eggs in one basket.
Travis C.
Great sack. Really helps keep our son comfortable during his nightly snooze.
Linda L.
Helps grandson sleep during the night. Have used two sizes now as he grows!
Stefanie B.
I was amazed when I first out this on. Not sure what took me so long to try it but within 30 seconds she stopped crying and was out. I went online so fast and bought 3 more and a swaddle for nighttime!! Obsessed with how great these work! Pure magic!
Kimberly P.
Quality is nice. I love the double zipper to ease night time diaper changes. I’m not sure that it has helped my baby sleep better after a month. He still wakes 1-2 times at 4.5 months of age. Overall I don’t regret the purchase cause anything is worth a try and I wanted another sleep sack to rotate anyway.
Rashmi J.
We got the sleep swaddle and the sleep sack for our baby and she loved both! She sleeps comfortably for hours in both :)
Alexis D.
Loves his nested bean sack! I'm no longer spending hours with my hand on his chest and he's sleeping in longer stretches after only a few days
Heather S.
I bought this for my 2 month old who was waking every 2-3 hours during the night. When we use our nested bean he will typically only wake once around 3am. We've even had a couple nights where he has slept from around 10:30pm to about 7 am without waking!
Staci F.
It’s an ok sleep sack. I wouldn’t say it’s a miracle worker though. It didn’t really help my son sleep a lot better. Maybe a little though. But the biggest disappointment was I got the 0-6 months bc my son is only 14lbs and it says it’s for height up to 30 in but my son is 26 inches and it’s basically too small already. Also I wouldn’t say it’s for year round, it’s pretty thin. He feels cold when he wakes up and he has fleece footed pajamas on underneath.
Olga T.
This product is very soft and the two way zipper is useful. Nevertheless, I did not find it super effective for sleep improvement, as advertised. It is just a sleep sack, therefore considering the price, would not recommend purchasing one.
Jamie C.
A week after using the sleep sack, my three month old sleeps at least eight hours every night. This is an absolute miracle product!!
Taylor Z.
Exactly what I hoped for, baby loves it, and he'll be able to grow in it! Great color, and weighted perfectly. I'm beyond happy
Thara W.
Baby loves it. Great quality material. Will be ordering more.
Danielle G.
My son went from waking up constantly through the night, to sleeping most, if not all the way through, the night! It was such an amazing difference for both of us. This momma was finally able to get some good sleep!
Sandra S.
I ordered this for my almost 6mo who was showing signs of getting ready to roll over. The first night we put him in it... Of course he rolls! I'm glad I had him in this and vs. his transition swaddle.
I'm loving how easy it is to put it on and take it off. Night time diaper changes are easy because of the way shower. I love the material and the weighted egg. I also like that it is sleeveless so we can dress him up or down as needed!
Katren T.
Wonderful product! Perfect for summertime my baby lobes it and it straps on top make it easy to remove.
Caroline T.
My baby has been a pretty tough sleeper since birth and at 3 months I was reaching the end of my rope with night wakings every 2 hours. I used some different sleep methods which helped some and then the Zen sleep sack really helped! Now we get 5 hour stretches of sleep- huge improvement! We will be buying another!
Brittany Y.
Not only did it help my baby to start sleeping through the night but as soon as I put it on my son he instantly knows it's time to sleep.
Jordan R.
We LOVE the nested bean sleep sacs. I used them with my first baby and they made a world of difference. He would sleep through the night with it on. It is a great sleep sack and worth the money.
Allissa T.
Our baby loves this sleep sack! He never let us swaddle his arms down but having the weighted egg helps him still feel comfortable. I just ordered the next size up as well as a premium for the warmer days
Leslie B.
This is our second sleep sack, he grew out of the first one. Definitely a life saver, he sleeps 7-11 hours a night Beware of the navy though, fuzzies come off on everything.
Taylor V.
Nice quality sleep sack and we do like it. Unfortunately however there has been no improvement in our 8 months old sleep. He is still up every few hours. We’re continuing to use it and are optimistic it will soon start to make a difference. We’ve been using it a few weeks so far. Fingers crossed for fewer sleepless nights in future!
Shibali N.
Absolutely love love love these well made amazingly soft and safe sleeping bags! Two way zippers help changing baby's diaper without taking the whole bag off an absolute breeze! Adjustable shoulder tabs and reversible bag so the bean egg is on her back for my 9month old tummy sleeper! Got 3 colors and all of them are absolutely gorgeous- Sand, Night sky and Lemon!

We love our nested bean! I was so nervous transitioning out of the swaddle, but the sleep sacks made it so much easier. Our son has been sleeping through the night since 2.5 months and we nurse our sleep sack every single night :)
Ashley V.
Works great!
kirsti d.
We love it!
Caitlin D.
Absolutely love Nested Bean, just bought the next size up as my daughter grows and she loves it! She can move around but can't climb out of her crib, and the weighted portion of this size is larger and works both on her back and chest!
Mycah S.
She loves it! We have been using it every night and she sleeps so well. So glad we made the purchase
Patricia Y.
We love the sleep sack. It helps her stay warm and sleep tight.
Karen M.
We are still getting use to it my baby is finally sleeping in her crib instead of on us. But I guess because she’s almost a month old and we are breastfeeding so we wake up on her demand on food.
Noemi C.
Best baby purchase!
Monica W.
I absolutely love this sleep sack! Nested Bean has continuously made our baby sleep much better at night while remaining safe!

Lindsay M.
Our babe has been a pretty great sleeper since the beginning! But I was nervous about transitioning from an arms contained swaddle to an arms free sleep sack. Nested bean made the transition easy! At 2 months we started putting the classic nested bean sleep sack on our son during naps and eventually when he started to show signs of rolling, we paired the sleep sack with his nighttime jammies and had no issue at all! Since we was 3 months old he has been sleeping through the night! We swear by this product!
Allyson S.
The first night my daughter seemed very uncomfortable in it(I expected her needing to adjust to it), the second night she slept 7 hours straight(prior she was only sleeping 3/4). Since then she has slept Atleast a 6 hour stretch!
John S.
Got theses for my daughter’s first baby she loves them.
Sarah L.
Not an ideal swaddle transition. The sleep sack didn’t provide a smooth swaddle transition. We ended up having to switch to the Merlins Magic Sleep Suit. The startle reflex and wild arms are too much for this sleep sack. We will try again when he is a bit older.
Michela N.
The absolute best! Since the first night I used this product my baby has slept better and longer through the night.
Lyn
My twins are sleeping wonderful! Great purchase have had a sound nights sleep since we began using this product!
Brittani P.
My baby girl loves this sleep sack! Before finding the nested bean zen sleep sack, she loved for us to lay our hand on her chest while she fell asleep. This gives her that same comfort! She falls asleep very quickly and stays asleep throughout the whole night. Highly recommend!
Jessica G.
My 2 and half months baby it’s falling asleep at 9pm, sometimes at 10pm, he wakes up at 3am to eat and then fall sleep again until 7am since we started using the zen sack! He was used to wake up 3 times at night! I really appreciate the rest!
Tanía R.
I initially purchased this sleep sack because my 8 month old is a terrible sleeper. She's a BF baby so she's constantly waking up for feedings. I put the sleep sack on her and the first night she slept for 4 hours straight. However I've been noticing her awaking more often and it's be she gets super hot. I put her in the sack with just a pamper and she's still sweating pretty bad throughout the night. My only complaint is that I wish the day had a lighter material or it was ventilated because I do feel it works. I keep trying it nightly but then I have to ultimately take her out of it because she over heats.
Mary G.
The weighted sleep sack is really nice! It hasn't magically made my 4 month old shell through the night, but he likes it and it's excellent quality. Honestly, I would buy more sacks even without the weight because of the quality. Soft cotton, a double zipper so can unzip from the top or bottom, the zipper is enclosed in more soft fabric, the straps have two snaps so you can expand as baby grows, it has snaps at all so you don't have to wrestle sleepy little arms through holes ... Overall I love it. It didn't fulfill my hopes of instant sleeping more than 2 hours at a time, but that's okay, I didn't expect it to be a magical solution. Its quality alone is worth buying.
miroslava L.
It is a good sleep sack but the weighted part does not make a difference.
Ryan W.
My little babe has such trouble sleeping, with the sleep sack we are all able to get more zzzz
Martina D.
The sleep sack is lovely. Unfortunately, after two nights the zipper seam started to come undone, so the zipper is pulling away from the material.
Olga U.
I like material, but go our house where temperature is 72-73F at night it’s cold for my baby (it says that it’s all year) so I have to order winter option , and it’s perfect
Amanda M.
Super cute! My little babe sleeps well in this. She was in the zipadeezip prior but their sizing is off a little bit. She needed a regular sleep sac anyway and access to her hands. She is a side/belly sleeper and every once in a while she will sleep on her back, but the beads don’t bother her. Will continue using the zen sleep sac.
Grace T.
Cute design and very well constructed. Super soft even after washing and the little chick on front makes me smile. Love that the zipper goes all the way around. The only issue is that it can be a little awkward to snap on the shoulders when the little guy is rolling around.
We’re not sure if the little weighted chick is what did it (or that baby is 7 months now) but he has been sleeping longer since we switched to this sleep sack for overnight.
Briar S.
My daughter sleeps so great and loves her sleep sack!
jessica l.
Love it!
Grace F.
We’ve had our sleep sack for a few weeks and unfortunately I haven’t noticed a difference at all. At 4 months, still up 2-3 times a night. I will say that he does go back down after feeding easily so that is something! I’m hoping that he starts sleeping through soon. I’ve been back at work for a few weeks and mama is tired!
Ashley F.
My son loves his sleep sac! He immediately calms down and has been giving me 7 hour stretches of sleep at 10 weeks old!
Kim S.
We love the nested bean sleep sac, our little one is a tummy sleeper and we put it on her backwards, it works perfectly!
Alexandria M.
It took a few nights for my baby to get use to her arms out… I really wanted to give up and continue to swaddle but she was able to get out of her swaddle so it was becoming dangerous and that in itself made me anxious and was not worth a good night of rest for me. I feel like it’s safe and she is use to it and getting a good nights rest. It’s easy enough to change her diaper in the middle of the night and not disturb her after nursing. Actually less disruption than the swaddle. I’m happy so the purchase
Alma B.
Love it must have the material is so soft my baby sleeps so good in this definitely perfect for this summer heat
Randalyn B.
Love the sleep sack. Previously had the
Diana G.
This didn’t work with my baby. I’ve tried both the classic and the winter zen sacks, and have been using them for over a month and my baby’s sleep has not changed one bit. The night wakings continue in the exact same way. Also the size seems a bit small. I got the 6-15 months old size, my baby is 7 months old and it seems he’ll outgrow them in a couple of months.
Magdalena M.
My son sleeps better in a fill swaddle at the moment due to his startle reflex, but I believe he will like it when we start taking his arms out
Amirah R.
Since transitioning my son into his room he been using these and so far so good! Not sure if it was sleep training or these sleepsack but he sleeps for about 11 hours !
Stephenie B.
Nested bean has helped our little bean sleep better all around! It’s lightweight, soft, & comfy. The weight is centered in the chest area and is just enough to comfort our baby to keep him asleep a little longer.
Robyn S.
The nested bean is a nice sleep sack. I like the ease of the zipper and snaps to put baby in the sack. However, I am disappointed that I did not see any improvement in my baby’s sleep.
Carly M.
My 4-month-old was an exceptionally good sleeper (going 5-7 hour stretches when he was still only 1 month old), but he was having trouble transitioning out of his swaddle, so we thought we would try the Zen sack. Unfortunately, it has not been going well. He now wakes up every 2 1/2-3 hours at night and he sleeps pretty fitfully for hours in the middle of the night. I am giving this a 3-star review because (1) he does fall asleep faster with it on, even though it doesn't seem to make any difference in how long he stays asleep; (2) he really loved being swaddled, so maybe he is just still missing that (although it's been about 3 weeks now since we last swaddled him) and (3) he's pulling his legs up a lot, so it's possible the new sleep difficulties are gas-related and have nothing to do with the Zen sack. But whatever the reason, our sleep schedule has taken a very unfortunate downturn.
Ashley H.
I use this plus the 8 sheep lotion and it works wonders!He's more on a steady schedule now and sleeps through the night
