It is important to have great customer review ratings from sleepers. These mattresses receive more praise from sleepers than many others, which should give you a good foundation to finding out if they will work for your preferences. Keep reading on to learn about the specifics and how they will relate to your body!
Being supportive is extremely important to how customers feel on their mattress and whether it is beneficial for the back and spine. These mattresses are good at supporting most sleepers. This means that you can sleep easy with these mattresses supporting you.
Reviewers describe these mattresses as having good edge support. This means that the sides of the mattress will be comfortable for most folks and the mattress won't sink under your weight.
Bowling Ball & Density Tests
It's popular to test support by resting a bowling ball on the top of your mattress. These mattresses have good consistency in the feel of their surface layers, which is perfect for customers wanting to feel secure about support.
It's a big win financially if your mattress is super durable and remains comfortable. And that totally connects to why durability is such a big factor for mattress buyers. That said, most brands are out for profits and quality is a secondary concern. Even in spite of that, there are still some great brands that build good products. These mattresses have good durability for most sleepers overall. Unless you are of a heavy build and use the mattress more than average, these mattresses should perform for you for 7 - 12 years.

Sleepers can be a picky bunch when it comes to their comfort (as they should be), which is why finding a product that most agree on is a great check mark to finding out if it works for you. Customers are very happy with these mattresses versus others. Take a look at the specifics below to learn if one of these mattresses will work for you.
Supportive mattresses are important to everyone looking for a healthy night sleep. Independent of whether you like soft mattresses, a mattress that leads to better spine alignment is key. Overwhelmingly, these mattresses provide a good level of support to their customers.
Many folks looking for a new mattress mention edge support as a top request. These mattresses are strong in the edge support category, which means sleepers notice good support when they roll to the sides.
Bowling Ball & Density Tests
The bowling ball test is popular in measuring mattress firmness and it is a great way to measure even support too. These mattresses offer good evenness throughout the sleeping surface to help with better spine alignment.
One of the most important items for shoppers buying a new mattress is durability. Getting up to a decade of use out of a mattress is well rated in terms of longevity. However, there are a lot of factors like body type and quality control that can affect durability. These mattresses impress reviewers with their durability. However, some that are heavier may see a slight decrease in durability.

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.View More Reviews
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!
My wife and I live this bed so much. When we don’t sleep at home we miss it. Very sound sleep every nightView More Reviews
Was pleasantly surprised with the support, comfort and overall better sleep provided by this mattress. I had a spring mattress for over 8 years and decided initially to go for a hybrid construction of spring and foam. This hybrid option eventually did not work out and I went with the all foam solution. All my initial worries were gone after that first night, the mattress does provide a good level of support and dissipates heat quite well. The only down side to this mattress was the smell it had for about a week after unpacking it, not a terrible thing to have to deal with for some days but not pleasant either. Regardless, I would highly recommend this mattress.
I bought the queen size mattress. It was delivered promptly and weighed 74 pounds. It wasn’t too hard to move around or dump out of the box (I have a low platform bed frame). Did a little adjusting of the cover or it would have opened lopsided. It is wonderful. It is supportive. There are no pressure points to cause pain anywhere on my body. I sleep with less tossing and turning so I’m more rested in the morning. I love my Leesa. Best $800 I have ever spent.
My Leesa is amazing. My back feels so good when I wake up in the morning (not always the case on other mattresses). I love memory foam but hate how hot it makes me feel and Leesa seems to have solved this problem. It reminds me of memory foam but I never overheat. And I don’t notice my wife getting out of bed in the morning. I paid a lot more for a Sleep Number and am replacing it with my Leesa!
Love this mattress! Firmness is perfect! I researched for a year and glad I chose the Leesa.
Going to bed has become one of my favorite times of day as a result of the Leesa mattress! Nicest bed I've had the pleasure of sleeping on!
I love the two Leesa Mattresses that I just bought. I now slumber in a deeper sleep. I don't wake up during the night tossing and turning, and look forward to going to bed! The pillows are fantastic. .
I love it. The best night sleep with out waking up stiff. It is very relaxing
We love our mattress! You sink in at all the right pressure points. We both especially like how our hips are sinking in just enough. It’s not slow to form like other memory foam beds, so when you roll over, your not leaving a hole and sitting on top. Our only complaint and the reason I didn’t give 5 stars, is the smell. During the first 2 weeks, it was pretty strong, it’s been about 2 months and it’s finally gone away for the most part. I’ll occasionally still smell it. I imagine all foam beds have this smell.
This is a very firm mattress. I wish there had been an option to choose a softer one. Also, deep-pocket sheets, which most new sheets are, do not fit well. They are much too big.
My whole experience with Leesa has been wonderful. I ordered the mattress and foundation and had the mattress two days later! The foundation takes a little longer but I had that within a week. There was very little off-gassing and I didn't find the smell offensive. I'm very sensitive to smells/fumes, I have asthma, but we were able to sleep on this bed the very first night. The mattress is THE most comfortable thing I have ever felt! It somehow manages to cradle you, like a big, soft marshmallow and provide the perfect amount of support. I suffer from multiple sclerosis and fibromyalgia and this bed has made such a huge difference in my life. I no longer wake up feeling like I've been beaten-up and while I rarely sleep through the night due to my illnesses, the rest and sleep I get on my Leesa has greatly improved my life. I've honestly never experienced this level of comfort! Thank you, Leesa!!!
totally awesome comfort after 6 weeks. Love it.
Best night sleep that I have had in a long time. The only downfall on this mattress is I never want to get out of bed!
I don't know why we waited so long
My wife and I LOVE our mattress. But that begs the question, how do you know you love it? First of all we aren't complaining about how we feel when we wake up anymore. We don't talk about buying a new mattress or even considering making a change. We fall asleep, and stay asleep (except when our 5 mo old wakes us). It's become a wonderful part of our evening, most nights I look forward to lying down! Great mattress for the price.
relieved that it's as good as the reviewers make it out to be and relieved that i turn much less than I did on a spring mattress. My wife's experience is the same. It's a deal.
We bought a king size Leesa for our master bedroom and loved it so much we bought a queen size for our guest bedroom. Our guests are going to love it!
I have to admit I was a bit skeptical that a mattress that is not super thick could be comfortable. My husband and I were both pleasantly surprised. The mattress has been wonderful. Not too soft, not too firm. It is well made with a beautiful cover. Love my new mattress
Best mattress yet
nice to finally get a good nights sleep.
Fell in love on the first night and have slept better since. It is the right amount of firm and soft and cannot tell when my husband moves next to me. I am a Leesa owner for life!
I am enjoying this mattress
I enjoy my mattress and will buy again in the future. Bed feels firm but contours to my back. It has lessened my lower back pain. Only gripe is that the mattress has a plastic smell upon opening that lingers. Had to leave windows open for a week to let it air out. Smell is still there but faint.
I love the matress and sleep great. It provides great support and breathes well. It still has a slight chemical smell from then it was made I guess but you get used to it.
Only reason I don’t give 5 stars is, LEESA tell us there may be some “off gassing” from the mattress for a few days. That means fumes emit from the mattress’s man-made material, a kind of settling process.
In the case of my mattress, it was like sleeping over an open can of paint for over a month. Then the “gassing” finally stopped.
I sleep really well on this mattress. Glad I bought it.
I'm a stomach sleeper and this mattress was too soft for me. I needed a mattress that was a bit more firm.
Our mattress has already developed troughs. It's still comfortable enough but there's no way it will last even 3-5 years, let alone the 10 a mattress at this price point should last.
We bought the leesa for our Special Needs son. He is 35 and has a hard time sleeping. He has loved it. Sleeps so much better and is in a lot less pain when he gets up. Thank you.
My husband just had back surgery and he has been loving the Leesa mattress. We both think it's wonderfully supportive and just the right amount of soft. We love it!!
Delivery and packaging was quick and easy. The light smell it had only lasted a day or two. As a heavier set guy, it felt amazing. It was super quiet, unlike a spring mattress. Very little disturbance with my wife. My wife on the other hand, hated the mattress. She's considered petite, and the more dense nature of foam mattresses meant she felt the Leesa to be a lot more firm than our last mattress. Sadly, I ended up returning it for her. It's a great option for medium to large folks. By the way, the return process was a breeze and refund processed about 5 days after the pickup. Amazing service.
My fiance and I are about a year into our Leesa experience and for both of us, it's been the greatest investment. She and I both travel extensively and we sleep in a lot of hotels but no matter how much we enjoy the mattress, we always look forward to coming home to the Leesa.
Super soft and well made mattress! We have been impressed with the quality and how it’s almost impossible to have a bad night’s sleep on it. It does run a little hot but I’d imagine not as hot as other memory foam mattresses due to the Leesa’s thoughtful construction.
I have gotten the best sleep ever! I’m a back and side sleeper and it’s been amazing for me! Definitely worth the investment! If you’re going to buy a mattress that will last and will allow you a great sleep, go with LEESA!!!
comfortable and supports my back well while being comfortable
Bought this mattress for our son, he is a very big boy, hoping the mattress won't start sagging in hot e middle as every other mattress we have bought for him! We will see!
I've been having difficulty sleeping due to a injury. I purchased the Leesa mattress and was finally able to get a decent night sleep.
After sleeping on this mattress for over a month, I’m ready to review it. This is by far the most comfortable mattress I’ve slept on. I also upgraded from my queen mattress to a king, which has been excellent. Along with the great sleep I’m having throughout the night, I’ve noticed I no longer wake up when my husband adjusts or gets in and out of bed. Experience with this mattress has been great!
For me, the Leesa Mattress has proven to be a wonderful mattress. I have bursitis in both hips; I have had zero hip pain with this mattress. I sleep soundly, comfortably. If my kids hop into bed with me, they can move without disturbing me, and vice versa.
I highly recommend trying this mattress. What price would you put on a peaceful night's sleep?
