See More ScoresThe Cocoon By Sealy mattresses have been a powerful addition to the mattress-in-a-box line-up. With their cooling all-foam and hybrid options, customers like their mattresses overall with an emphasis on those that want more support from their foam mattress.
Using generations of expertise and learnings from building mattresses, Cocoon by Sealy offers the Chill Mattress in an all foam version with a 10'' profile as well as a newer 12'' hybrid option. These mattresses are priced competitively and have had good reception from reviewers.
Here is what's inside the Cocoon Chill Memory Foam Mattress:
Layer 1: The Chill Memory Foam Mattress has a woven cover made of a polyester blend with phase change material to help dissipate heat.
Layer 2: Next comes a layer of high-quality, perfect fit memory foam that adopts to the sleepers body.
Layer 3: The third layer is a cushioning, responsive comfort foam that helps to reduce motion transfer while also preventing a 'sinking' feeling.
Layer 4: The base layer is made of a heavier, robust foam that's more durable to provide support to the layers above.
Next, we will take a look at what's inside the newer Cocoon Chill Hybrid Mattress:
Layer 1: The Chill Hybrid Mattress starts with a cooling cover layer that helps absorb and dissipate heat.
Layer 2: Next comes a layer of perfect fit memory foam that gives sleepers a soft and supportive feel.
Layer 3: Under the foam is the Active Support Technology® coil layer. These breathable, fabric encased coils offer targeted support while further contributing to this hybrid's cooling properties.
Layer 4: The base is an essential support layer engineered to be resilient and durable in order to support the layers above.
Most agree that these mattresses have a very comfortable feel. A few that wanted a softer option complained about the mattresses being too firm for their liking.
Cocoon's Chill Memory Foam Mattress and Chill Hybrid Mattress are on the firmer side for lighter sleepers, so if you are looking for a very soft mattress, this isn't it. For average-sized side sleepers, the Chill Hybrid may be good for you, while the Chill Memory Foam may work better for stomach sleepers and heavier folks.
The Chill Hybrid Mattress is a medium firm in feel, so medium build folks should experience help with back pain. For those that are heavier, the Chill Memory Foam should be a good option and provide proper spine alignment.
The Cocoon Chill's cover will provide a cooling surface for most sleepers. Some that are very warm sleepers may experience some heat retention after some time.
These mattresses are ideal for stomach sleepers and back sleepers -- those with lighter body types and are side sleepers may feel it is too firm.
Just what I expected but I might need to exchange it. I bought the soft mattress. It feels like foam on a rather firm, supportive mattress. Sounds ideal for a side sleeper, but I'm waking up a bit sore in lower back. Honestly, it could be my medicine dose. I have to do a good trial with better pillows, regular dose of my medicine to be scientific. Arrived a day early. I managed to unpack it on my own. I'm a short woman with back pain and I didn't hurt myself unpacking it. It would be super easy for two people. I'm very happy i can exchange it if i need to.
The process to buy the mattress was so painless. It was so much better than stepping foot into a mattress store - I will never do that again. My husband threw his back out and we desperately needed this new one. So I called customer service and told them what happened. They were SO helpful and actually over-nighted the mattress to us so my husband could recuperate faster. I am very grateful. One thing to note - even though we have the "soft" version, it is much firmer than what I was expecting. It's not one of those foam mattresses than can be difficult to move around in. This definitely has a good amount of firmness to it. Even my husband, who loves a good, firm mattress, says this is great for him!
For the first time in months I wake up rested and NO back pain.
Still enjoying a great nights sleep on this mattress! Seamless process from selection to delivery to set up.
Delivery was timely, package was easy to open, mattress came to life immediately. Our mattress is firm and comfortable. We love it!
The morning after sleeping on it, I got out of bed and starting saying, "My back hurts." As soon as I said it though, I realized it wasn't hurting! I was just so used to complaining about my back hurting that I did it automatically without even thinking. It keeps me very warm a night!
I've only had my mattress for about 2 weeks now but so far I'm happy with it and am definitely sleeping better. It really is more firm than you would expect out of a "soft" mattress but it's actually what I prefer. I feel like I have more support that way. My best friend has a Leesa and my Cocoon is definitely a bit firmer than hers. I've bought foam toppers in the past and they never held up over time. I am hoping this foam mattress doesn't let me down. I have to say it is a really good deal compared to other bed in a box companies out there and the reputable company name sold it for me. Of course the great reviews helped too ;-) I plan on updated my review in the future to let you know how it holds up over time. Good luck, friends!
We love, love our new Cocoon mattress and foundation. I don't want to get out of bed! I'm now ordering them for our son's room and our guest room, too! Great customer service when I reached out with questions.
What an awesome mattress. The only thing I would suggest re: the cocoon would be to unpackage/wrap it on the floor completely before putting it on your bed frame. You have to take it off to get the last wrap off anyway.... Money well spent, very worth it, we will see how it holds up in the next few months before we come back to update our comments.
I just wish it is firmer. However, the piece is not firm enough for me so I have to return it.
This bed is very firm. From my personal opinion, I would give this bed a 7.5 out of 10 on a firmness scale. This bed causes me to wake up with back and neck pain, that I did not get from my older SPRING mattress. As for the "chill" cover, it does make the mattress feel a slight bit cooler to the touch, but after 15-20 minutes of laying in bed, you can kiss that coolness goodbye!
Thanks for the great bed.
The Chill Soft mattress was a great purchase, as it has given me a better nights sleep during the day, as I work nights. I have had problems with other mattresses, due to back aches from work, but the Chill Soft has helped ease my back pain. The Chill Soft does seem to sleep cooler than my old mattress, though not as much cooler as I wish it would be.
I bought 2 twin for my kids and they loved it! Firmness is just perfect. We currently have a Serta bed that we paid over 2k, some spots in the bed are now too soft and the edge support is really bad. Tried to claim for warranty but it seems like they're doing everything they can to not cover it. NO MORE SERTA FOR US!
The mattress is very comfortable and keeps my hot sleeping husband cool as advertised. It is on the firm side of firm but otherwise we are completely happy with our purchase. The delivery and set up were super easy, too.
I am a very sensitive sleeper, but once you lay on this bed you go off to wonderland! Usually, I get up several times during the night but with this bed, I'm dreaming and or sleeping until morning. The con is sometimes my ears or shoulders are little sore from being in such deep sleep but your body gets used to it and adjusts. Now I can't sleep on anything else. What am I going to do when I travel now?
Mattress arrived on time and was easy to open and set up. It is very comfortable both for me and my husband.
Wish I would of bought one sooner . Haven't slept this good in years!
So easy to purchase. So easy to unbox and unpack. So easy to place on a boxspring. So easy to sleep on from the first night. My Cocoon is the best bed purchase I've made.
Great mattress and I feel the wooden slat in the foundation.
First night was kind of rough but I think my body was adjusting to the new bed. After a few days of breaking it in I found that I'm more refreshed and limber with no more back pains. I would recommend this bed to anybody who's in the market looking for one.
I love everything about this bed super easy to put together and the mattress is so comfortable. I got the chill king mattress best decision, I couldn't be happier!
This is my third cocoon mattress. I initially purchased one for myself a year and half ago, I love it so much that I bought my mom a cocoon classic and a cocoon chill firm for a dear friend who was having back issues. They both love it and their aches and pains are gone. To top it all, unparalleled customer service.
I purchased this bed back in March 2017. It's now November. I love this bed now but I didn't love it when I first purchased it. I felt it was as too hard even though it was the soft version. However, my husband really liked it so instead of returning it, I bought a memory foam topper. That helped immensely. I now get amazing sleeps. I would definitely recommend this bed. The price was good as well as I had a coupon for $100 off.
The mattress cool at night. It is also very comfortable and great on my back.
Great support. Keeps me cool and comfortable. Best purchase I made last year. My only criticism is that the edges of the mattress are strangely too soft, softer than the rest of my firm mattress. It is too easy to slide off the edge when one sits to put on shoes. Otherwise, best mattress ever!
We recently got the cocoon soft mattress for our daughter. It is hands down the most comfortable mattress in the house and is great during story time.
Love how cool my mattress stays and its amazingly comfortable that i don't want to get up in the mornings.
Our new bed is so comfy! I have been happy with it since day 1. Ordering was so easy and so was set up. I will definitely buy another one for our guest bed.
I like the bed, but unfortunately it smells pretty bad hopefully the smell does away. I slept on it the first night and the next morning I felt dizzy. maybe it was the weather outside or something, but it could of been the flumes from the bed. I would suggest to anyone who buys this that they put it in a room after it has expanded and let it air out for a week. who knows maybe two weeks. I ordered a firm mattress, but maybe I should of ordered a intermediate. I don't get into it and say aww that is so comfortable.
It was so easy to get this delivered to my new apartment and I didn't have to wait for delivery men. The mattress is comfy and afforable.
It took a bit to get used to the difference in a foam mattress compared to a typical spring mattress. After the initial few nights of getting used it, I can't wait to crawl into bed at night!
We always purchase a firm mattress and this mattress is the firm we desire! The customer service agents are very helpful in answering any questions before purchase. It shipped quickly and was easy to set up. Thank you Cocoon for giving us a good night's sleep!
The way it's made and the ease of ordering and receiving it. The thickness is great, easy to get in and out for an elderly person.
I Love that I feel like I'm getting a full body hug while I sleep! Not too firm, not too soft, a perfect snuggle!! Love it!
I bought this mattress to put in my spare bedroom. Since purchase, I've had a few guests stay over and tell me how great the mattress is and that they were surprised I sprung for one of those -pedic mattresses that cost so much money! I tried the mattress out for myself one weekend, and decided to order a King for my bedroom. I usually toss and turn at night, but woke up in the same fetal position I laid down in the night before.
a comfortable mattress but soft feels too soft to my standard. Would be better if there is another choice between soft and firm!
The delivery process, unfolding and making the perfect bed to fall asleep in....I love this mattress and really pleased with the right amount of firmness for the "firm". Not too hard, and definitely not too soft--just RIGHT! Thank you Cocoon for making my nights better :)
Comfy. Sheets don't stay on well. Best sleep I have had in a while. Don't have to have my back popped back into place every day anymore.
Bought this bed after doing extensive research on different brands. The Cocoon bed came out a winner, far ahead of the others. My Cocoon bed was delivered promptly and set up a super easy. This is hands down the best bed I have ever slept on. I love this bed!
This mattress is nice & firm...I rest well! I recommend it.
First, I do enjoy my bed but I am not sure how life changing it has been for my sleeping. Second, I would recommend to others because everyone is totally different and this bed could be perfect for someone else. However, the chill part still perplexes me because I live in AZ which is why I purchased the chill version but it might be a myth. I certainly do not feel more "chill" when sleeping is all I mean.
I have issues my whole life with insomnia. I also suffer fom extreme stress due to tragic loss of several loved ones This bed has helped change my life. I get in it and just melt. The days go away and I drift off easily. Im not even having to take my sleeping meds anymore. Thank you, Cocoon!
So it's only a week and I think it takes a bit longer to know for sure but it seems good so far!
I was a little leery of ordering a mattress online without first being able to test it out, but from the first nights sleep our fears disappeared. Very supportive without being hard as a rock. I cannot wait to get into bed every night.
This was by far the easiest way to buy a mattress and is the best sleep I have had in years.
This mattress is amazing. I have had it for three months or so, and every night I lie down in it is like the first. I sink down into it just the right amount, and the comfort is incredible. Shipping was quick, and I have no complaints there. The frame, which I would also recommend, is very nice. It's a lot lower to the ground than I realized when I ordered it, and it makes a few squeaks every once in a while. Overall, it's totally worth buying to complement the mattress. TL;DR: Approve, get the foundation, if you're going to buy the mattress.
Love the ease of receiving it, unpacking it was fun! It has a very nice look, I ordered the soft one, but it was still too firm, I now have 2 foam style pads on it and this has helped.
got the chill firm to keep us cool at night and help with the softer mattresses we were encountering. got the box, opened it up and its been a great nights sleep ever since! a friend also has a cocoon and loves it. now we can see why!!!!! don't hesitate to purchase this mattress--its all reward and no risk! sleep well my friends!!!!!!!! #CUCKOOFORCOCOON
We were totally shocked how comfortable our new bed is. I have Fibromyalgia and a host of Chronic Pain issues and I'm able to lay in bed with additional pain. Who would've thought a foam bed would help someone with extreme pain!!
I love my new Cocoon matress!
like sleeping on a cloud is an understatement
I'm getting the best sleep I've had in years! The compact way it was delivered was perfect. I was able to get it up to my third floor walk-up all by myself. Easy peasy. Hooray for better sleep!!!
Love everything about this mattress!
Bought two new mattresses for the kids. Easy delivery and setup. They love the new beds and we couldn't be happier with how they are holding up. It's been a few months and they are still loving how comfortable they are.
The bed has been comfortable so far. I am very happy with it. However, I asked Sealy for a specific delivery date, which they said was out of their hands and that I should contact the delivery company when I get the shipping notification. I was never notified when it shipped and my order status never changed, and it delivered when I was out of town and sat outside for 3 days. I'm glad it wasn't stolen!
We sleep more soundly now as we don't feel as much movement when one of us turns over, etc. There was some "new" odor to the mattress for the first week or so, but only noticeable when my head was directly on the mattress vs. my pillow. It's a heavy package (85 lbs) and the unpacking instructions weren't really accurate because there is a plastic sealed envelope on the mattress that must be removed AFTER the initial outer wrapping is removed. This required slicing open the plastic and slipping the packaging out from under the mattress. It's still new, but for now I really like the mattress and how easy it was to get it here.
I love this bed. No box spring to deal with, easy to rotate and unpacking was simple. I have had mine for 10 months now and have seen very little break down. Well worth the money...will buy again in future.
My husband and I had been sleeping on a rather aged mattress for over 10 years. each morning one of us would wake with some various ache or pain. After seeing a commercial on tv for the Cocoon by Sealy we decided to give it a try, and I can honestly say that it was the best decision ever. I for one feel like I'm sleeping on a cloud and have not had a bad night or an achy morning since the mattress arrived, my husband says too that it is the most comfortable bed that he has slept on. We can't recommend it highly enough!
I have a bad back and this mattress is the best thing ever! My back doesn't hurt when I wake up in the morning!!!
Great mattress great price point
I was skeptical about ordering a mattress online, but after reading reviews and the 100 night guarantee, there really wasn't any risk. Due to a back injury, I had been sleeping on a yoga mat on the floor for several weeks, so when the Cocoon arrived, I was in Heaven. It's been four months and I still look forward to crawling between the sheets each night. The best purchase I've ever made.
We went back and forth when moving our child from co-sleeping to sleeping on their own. Our mattress is a foam mattress so when we tried to lay him down in a crib, with the typical crib mattress he was having none of it! He would cry and cry, so we decided to go with a foam mattress on the floor, montessori style. My husband did a lot of research and we visited a few mattress stores (which was a new experience for both of us). Mattresses are expensive! Who knew? He told me about the cocoon and we compared the different in store mattresses to the specs for the cocoon. We wanted something like ours, but the cooling option was great since our house does not have AC. When transitioning him to sleep on his own, I spent a lot of nights sleeping in his room and the floor is hard, so I decided I was going to move him over and do some bed sharing. While it states soft, this mattress has a lot of support, and for a twin both a squirmy toddler and a pregnant mom fit no problem. The cooling feature is great, and since it is foam I have no qualms with leaving it on the floor. We will be purchasing another for our next son in the near future! Love this and recommend it to any Moms who ask. We were never worried about the foam and suffocation issues even though it states soft, it is not a sinking soft, it is a comfortable soft that still holds you up. If you are on the fence try it out, you will not be disappointed
I liked that the mattress was soft and fairly comfortable, but it didn't seem worth the price to me personally. Maybe that's because I'm young and not rich and frugal with my money, but ultimately, it didn't turn out to be an investment that I'm comfortable with at this moment.
We did a lot of research and tried another brand before buying a Cocoon - the other mattress was so uncomfortable I couldn't sleep on it. There is a bit of a break-in period, and we had to put a mattress topper on it because it was too firm. We've had it for 7 months now and it still seems about as firm as when we originally bought it. I wouldn't say it's changed my life, but overall, I like the mattress. It works well with the adjustable bases we purchased.
Very comfortable and good quality mattress for a good price
I bought the chill firm mattress in June. Before getting my cocoon mattress I was suffering back and hip pain to the point that I was waking up during the night. It took a few nights to get used to the firmness and the chill feeling but I love it ! I have recommended this mattress to everyone I talk to that mention they need a new mattress ! I wish I had not waited so long before I ordered. This is a great product , well worth the money and the ordering experience went smoothly . I don't have any complaints.
We are so happy with our purchase. Will definitely buy again for our guest room!
So happy with our purchase!
I really like the chill matress, it's very comfortable and I enjoy the cool feeling; however, I would prefer a little more firmness, but not rigidly firm ( i.e. - "extra firm"). I would have ordered the "chill, extra firm" mattress, but frankly, that description scared me off. I also think the price is very reasonable. The pillows are wonderful! They are comfortable and just the right firmness. As for the base, I th…
This our second Chill mattress. We purchased this for our spare bedroom and have not been disappointed. The sleep has been outstanding, comfortable and firm enough to keep your back from complaining. This is based on our King mattress which is why we purchased the second for the spare bedroom. Our guests have said it was a great night sleep and that they woke up refreshed. They also loved the chill feature which ad…
I have only experienced one night on this mattress but I must say so far so good. Sealy really nailed it with that balance of plushness mixed with support. The brand new bed odor is not overwhelming. The delivery came within a few days. I was able to set it up on my own and the free sheet and the pillows were truly an awesome bonus. The sheets are very soft and smooth and the pillows are very nice. I would recommend
The medium soft is perfect, I thought it would be too soft but it's more towards the medium to firm side. Perfect for us!
Sleeping is no longer a pain!
It is exactly what I read on the descriptions
Talk about information overload! If you are NOT a back sleeper you can skip this review. However back sleepers hang with me. Like the the rest of us you are searching for the "best mattress" Well im excited to share with you that the Cocoon "chill" FIRM by Sealy is a dream to sleep on. What makes it a dream to sleep on? 1. Comfort. 2. Quality workmanship 3. Value "not going to break the bank" 4. Sealy support team…
This is my second purchase of an extra-firm Cocoon mattress and I am very pleased with the overall quality and comfort. Super easy to set up too.
Sadly, I had to return. I had read many reviews and watched several YouTube videos and was hoping this would work. But it was so firm. I did not sink in at all - I was hoping for a bit more memory foam feel, like TempurPedic. I'm pretty light, about 102 lbs, so that probably doesn't help. The return process was delayed by Cocoon (they said they never received my email). I re-sent my original email and finally…
I bought an old house and my queen mattress and box spring would fit up the stairs to my bedroom, so I purchased a Cocoon and it has been an amazing mattress. It is so much better than my mattress and box spring combo.
I love the overall experience with the product, but for me personally, I need a softer feel to my mattress. I ended up returning the mattress and had NO problems with the return process at all. If Cocoon offered a softer mattress I would have been all over it.
I used to wake up with hip, back and neck pain. Those days are over!! This mattress and pillows are so comfortable! The chill really does keep you cool too! Very easy set up as well.
very comfortable great value
Cocoon chill is comfortable, but it does take time to adjust to the feel. Any concerns that I had about this mattress have been quickly resolved by Casie from Sealy customer service. Again, great mattress and equally amazing customer service.
The mattress is so comfortable!
I was skeptical, I had 4" foam toppers. And many people were not "bed in a box" advocates. BUT my wife and I are thrilled. Like sleeping on a cloud, with equal body support. No more achy breaky mornings. Woohoo!
I ordered the medium soft because I absolutely hate soft mattresses, but too firm hurts my body. Well this mattress is perfect, it has just the right amount of softness and firm in the right places. It's so comfortable that I can't keep my 8 year old out of it. He slept like a baby the first night. I definitely recommend this mattress. I don't really understand the chill part of it. I never notice a difference, but…
I actually like this mattress because I am a stomach sleeper. It sleeps cool, probably because you don't sink in much at all. It also absorbs motion transfer well. However, my wife is as side/back sleeper and she does not like it. She has had trouble sleeping at night and her joints have been achy since we got it. If you are a stomach sleeper, and you know you like firm beds, this will probably be a good mattress fo…
I needed something firmer than my previous mattress, but also wanted it to be comfortable and cooling. This mattress fit the bill and while a bit anxious ordering online without testing it, I took a chance. So far, so good!
I received my Cocoon mattress topper on April 14th, and today is April 22nd. It is comfortable, however for 8 days now it is emitted a very toxic, putrid smell. We can smell this unusual odor not only in the bedroom, but throughout that part of our house. Today we put it out in the open air and sunshine for the entire day, and will see if that help. Has anyone else had this experience, or can you suggest a way to fix this problem? If not, I may have to return the topper.
It's been over a month since first placing this order and still not fufilled. Cocoon's web site leads customers to believe everything will ship within a week and you'll be enjoying a comfortable sleep in less than 2 weeks. My first call to find out why it was not shipped was answered with that they had a manufacturing problem with the mattress, but it should ship in a week. The next week I was told the mattress was ready, but the "Free" Pillow Case and Linen bundle was out of stock and they did not ship the seperately - funny when the order arrived the mattress was in one box and the Bundle in another. The outer box of the linen set was labeled correctly, but the inner package was labeled differently and contained the wrong size sheets. Their customer service representatives do everything to assure you that they agree you have the right to be upset, but never have they followed up by keeping you up to speed with the current status. Today, 38 days after ordering, 18 days after delivery, all they have assured me that it should be shipped within 3 days - I am not holding my breath since they made that exact same promise before without any result. Oh, the mattress is a bit soft, but I will give it the 100 day trial. By the way, please note that they have been running the same "Order within the next so many days, hours, minutes and you'll receive the "Free" pillow/linen bundle and 35% off" for months now.
