The Eight Mattress was first known for its smart mattress cover and tracker. With its initial success, Eight was one of the first companies to launch a 'smart mattress.' Their integrated tech offers bed warming, smart alarm (that wakes you at your lightest sleep level), an integrated mobile app and sleep assistant, and further customizations with your smart home. With mattresses at different pricepoints and firmness preferences, this is a great brand to consider!
Mlily is a mattress brand that is well known for being a global partner of Manchester United, and is available at brick in mortar mattress retailers and on Amazon. Their mattresses are made with trendy materials like bamboo and aloe vera, which is a major differentiator vs many other online options. They blend these materials with foam mattresses and also have select hybrid options as well.

Starting with a brand that has a good customer satisfaction rating is a good tactic. Based on online customer sentiment and review data, these mattresses are highly regarded by customers. Sleepers describe having good experiences with the brand and feeling comfortable in bed. Take a look below for the mattress specifics!
Being supportive is extremely important to how customers feel on their mattress and whether it helps alleviate back pain. These mattresses are good at supporting most sleepers. So, if you were worried about support for these mattresses, you can rest easy!
Most sleepers say they are happy with the edge support of these mattresses. This means that you can be comfortable sitting on the side of the bed and the mattress will prop you up rather than sinking down.
Bowling Ball & Density Tests
Some online reviewers use the bowling ball test to measure firmness. Customers report that these mattresses offer a good consistent surface, which is great for those that want to feel secure in their purchase.

Finding out how sleepers really feel about a mattress is difficult business -- especially with companies coming in and out of the market quickly. These mattresses, unfortunately, don't score as well with customers. There are still folks that love their mattresses, but there are many others with complaints. Learn more details about the mattresses below.
Support isn't the same as firmness. Great support is when a mattress cradles the hips and shoulders to align the spine. Overall, these mattresses have had some mixed reviews when it comes to support. Most find the mattress to be comfortable at the beginning, but some have reported support issues as time as gone on.
For those with mobility concerns or like to lay close to the side of the mattress, edge support is very important. These mattresses do well with edge support at first, but some didn't think that it was as comfortable long term as they had wished.
We all want a mattress that is going to last over a decade, and when our mattress is instead something crummy that causes us pain after only a year, this is the worst. That said, finding a mattress that is comfortable and durable is really hard these days. With more choices than ever, many companies are sacrificing quality to make a quick dollar. With these mattresses specifically, some reviewers had discomfort over a short period. Not every customer experiences durability problems, but do some extra reading to make sure that your choice works for your body.
Although I have experienced bugs with my data collection, the overall concept of this bed is amazing. I am excited for future types of smart beds.View More Reviews
I like the Eight sheets because they are soft but very breathable. You can feel the difference from common Egyptian cotton. Glad I bought these!
This mattress has been really helping with my lower back pain, I can sleep comfortably on my back and side and can stay in bed longer than before without feeling that morning soreness. The description say 10 inches thick but it almost seems like 11. You can also buy it with the heated cover and sleep tracker, maybe I'll upgrade one day.
I like my Eight so far. It's nice and supportive. Feels cool at touch. My favorite tech features so far are the home integrations. I connected it to my smart lights and it's quite cool. Recommend it to every smart home owner.
If the Eight lives up to the website, I'll be in sleep heaven.
I started being addicted to seeing my sleep tracker in the morning. Eventually it was driving me pretty crazy at night thinking about if I was going to sleep well or not. In the end, I don't think the tracking thing is for me. It's just an extra thing to worry about.
The site was very easy to use and the purchase process was very straight forward
Product says it all and I hope it is as good as the hype.
The Eight Sleep Mattress brings a solid mattress and intriguing technology layer to the table.
It is a good bed, but some of the features didn't work after a short time. I think it may be that you use it too much it stops working? But, it's the start of a new technology so hopefully there future products don't have this problem.
This is a great bed -- I am really happy that I decided to try something new.
I've been using the mattress now for nearly two months. Let me break my review in to two parts for the mattress itself and the smart mattress pad.
The mattress :
As a previous owner of a coil and foam hybrid mattress I was initially skeptical whether an all foam mattress could deliver. Initially me and my wife felt that the mattress was a little too soft for us as side sleepers. However after the first week the foam adjusted greatly and it became a very pleasant sleep experience.
Eight Mattress Pad :
Great build quality. Easy to set up. Took just a few minutes. I had a few issues setting it up on Android first but it worked like a charm with my wife's iPhone. No further issues using the Android app otherwise after that.
My wife loves the ability to remotely control and preset the heat settings for those chilly winter nights. I myself like the smart sleep alarm that syncs with my phone and the IFTTT integration that allows me to activate the heat mode with our Alexa and the Google assistant. Hopefully the company will expand on IFTTT triggers and commands in the future.
I've always been used to spring mattresses and since I moved to the US I had hard time to find the right mattress for me. I suffer back pain problems and it took me a while to find the right mattress. I tried soft and hard mattresses but none of them worked well. Since I already had the eight sleep tracker I decided to try their mattress and I'm really happy with this choice. I have had the mattress for a couple of months and the firmness is just right for me. My partner also like it better than our previous one, so we'll definitely keep it!
I purchased the Mars plus smart hub thinking the hybrid design would be more supportive. First, once I set up the Smart cover (exactly as the directions stated) it did not work and their support team takes 3 to 5 business days to respond... so I could not use that feature for that time frame. Eventually, it was fixed. However, the smart cover makes the mattress VERY hot and retains heat! I kept waking up with back pain and just assumed I did something the day before. I went to chiropractor and got a massage which helped.. but then every day I woke up with back pain... I decided it was the mattress. It does not provide adequate support for the back and causes one to toss and turn all night. I am going to return it now. Beware don't let the fancy tech fool you into buying this mattress.
I bought king size Saturn+. It is a great mattress. The best Mattress I have ever had. Fast shipping, easy to set up, firm. Everything is perfect. I wish I could know this mattress earlier.
I'm a week in with my new eight mattress and in love. I've always been given used mattresses and finally decided I deserved a new one. They technology is really what sold me and the fact it delivered to my door! I'm in love. Especially fact I can warm my bed before getting into it!
I bought my king mattress over a year ago. and yes i just set it up on 2/17/2018. but after sitting for over a year in the vacuumed pack plastic It came back to size in no time. i even got to sleep on it that nite. I think i am going to enjoy it very much. Thank you eight team good job
While I love my new mattress I feel the promotion Eight is running is a bit misleading. After purchasing a purple mattress and returning it and extensively researching other online mattress companies I settled on the Jupiter smart mattress. On the Eight website, they are having a promotion stating 2 free pillows with purchase. Upon receipt of the pillows I noticed these are not the ultimate, adjustable pillow shown on the website (the ONLY pillow shown on the website). I emailed customer service, who has been nothing but helpful regarding the questions I had, and was told that the regular bamboo pillows I received were a product of Eight, however, the promotion does not specify which pillows will be received with the mattress. I don’t see any other pillow options so to me that implies you will receive the adjustable pillow. Anyway, that’s where the three stars come in. Otherwise, I would’ve easily given 5. Just seemed a bit sketchy at the end of it all.
the bed is uncomfortable to sleep on. i wake up stiff and in a lot of pain in both shoulders and my back. My sleep quality has greatly diminished since using this mattress. I have also noticed that my arm goes numb by the morning, and this has only started since sleeping on this mattress. both in purchasing and returning I have not had a pleasant experience with the customer service. it's nearly impossible to speak to anyone, it takes more than a week to get a response via email, and i am continually given excuses as to why it takes so long to return any communication. We are returning this mattress.
We purchased a mattress and it was too firm for us. We contacted them and started return process---which was to send back the sensor and not the mattress. That was immediately returned and received by Eight. They informed us we COULD donate the mattress and turn in receipt and gave us listing of places to contact which we are out of their service are. Contacted local rescue mission and they only take mattress and box spring sets, so no luck there. THEY WILL NOT REFUND US OUR MONEY!!!! We have sent email to them again a week ago now with no reply---NOT GOOD CUSTOMER SERVICE!!!
This mattress is the best I've tried so far. It looks very simple so I was scared that it would be low quality but actually in its simplicity it stands out because it is all about the comfort not the looks. And the tech is a great innovation. I had never tracked my sleep before and I have discovered that my room temp is higher than suggested and have been adapting it so I can sleep better. Interesting little fact..
love this bed, thanks Eight for making such a good mattress
I'm a stomach sleeper, and this mattress does wonders to support my terrible sleeping habits of being on my stomach. No more back pain for me
I tried a couple other brands before settling for the Eight mattress and I wouldn't change it for anything. I'm a side sleeper and other mattresses gave me a hard time on my hips. This has been the best so far. I'm sticking with it!
I bought it because of the technology. No other mattress in the box has this. Definitely worth it.
I am so in love with my eight mattress. It's super comfortable and I sleep so soundly every night on it. I look forward to getting into bed every night. No other mattress can compare. My other mattress was very expensive and it's sitting to the side right now because this one is the best!
The Eight mattress has been great for me and my husband. We enjoy how comfortable it is and every night it feels like a new bed, fresh, cool, enough bounce and great support. It is a great buy
This bed is so unique. I had never heard about it and a friend recommended it because I feel cold at night. It changed my sleep forever. The bed warming is so amazin keeps you cozy in the cold winter nights. And the mattress is super comfy too!
This is the 3rd foam mattress that I've tried. It is not only the most comfortable, but the technology that it has makes it even better.
They have a beautiful showroom in Tribeca NYC. I went there to test the mattress before buying it. Even if they offer 100 days return I did not want to get a mattress I don't like. They were nice and I love the mattress immediately since from the beginning.
I tried other 4 foam mattress before this but this one has the same comfort, a cheaper price and all the technology. No brainer
I checked a lot of reviews before buying and this was the only mattress with technology. It is so cool to have the same comfort of other mattresses (I tried Casper and Leesa) and sleep tracking and warming.
With my old mattress I used to wake up with back pain. Now I feel great.
I got a mattress first and then I bought a second one for my parents. They love it.
I originally bought the smart cover and recently the whole smart mattress. I love how this products keeps improving. It learns from my habits and becomes more accurate. Great job!
We have the King Size eight mattress and really like it. Our bed jumps on it during the day so we have to delete those sleep tracking sessions from the app which is hilarious. Great bed though!
I've been mattress shopping many times in the past two years. Tried many beds. Eight is the winner without a doubt. I will never buy a regular bed again!
This bed is top notch, great innovation and I have been sleeping better than ever. Kudos to the Eight team for creating this smart mattress.
Loving it. Recommend it to anyone looking for an affordable comfortable mattress.Easy to buy, easy to love
This mattress really has it all. They are knocking it out of the park compared to every other mattress you can buy online. It's affordable, comfortable, has technology that is super cool to see how you sleep. I'm enjoying it every night and can't wait to see how it progresses with more software features.
I have a MLily Bliss King Size Mattress and it's the BEST mattress I've ever slept on! For the first time in YEARS I am sleeping through the night and I don't wake up with aches and pains! It also doesn't make you hot! LOVE THAT! You can't pay enough money for how a great night sleep makes you feel in the morning! So thankful I have my MLily Bliss!View More Reviews
I bought this mattress its by far the most comfortable mattress I have ever owned. I previously owned a tempurpedic mattress and it use to always make me hot, I had had back problems for years until getting one, and within 2 days of sleeping on it, they went away. The cover on the mattress feels great, this was a fantastic deal and I'm thrilled.
Best mattress I have ever owned. Good support yet soft and comfortable. My wife and I are now spoiled as we cannot sleep on motel mattresses
It feels like luxury at first. I've owned a queen size for about a month now. I have woke up almost every night with severe sciatic and mid back pain. It's way to soft and offers no support.
I purchased this months 4 months ago. It has the cooling gel in it, but I wake up with night sweats and hot., I also started to develop an allergy to it, I sleep on my back, it causes me to itch like crazy, and doesn't stop. I had to buy a mattress topper 3'' thick to put on top of it to keep away from the memory foam, even with a mattress protector on it. Helped some, but now I am stuck with it. It is however very soft and comfortable. Pity about the heat and itching though. I upgraded to this from a Serta memory foam without cooling gel, and I should have kept it.
Without a doubt the WORST investment in a mattress I have ever made. One star is six too many.
Thank you Elliot & friend for personally coming to my house to drop off my mattress the next day after purchasing! Couldnt be happier! THANK YOU! - Christy W
This is the second Mlily mattress I have purchased in the last two years. I love my original one though you have to spin them around every other month or so because they really do form to your body...They also tend to be a little warm, I live in Ohio and rarely used more than a sheet all winter long, with my house set to 62 (62 is totally not low because my house keeps the heat in so it feels warmer for those of you that think I might possibly be a penguin). This mattress I bought for a friend of mine and it's just as comfy as mine. The off gas usually goes away within 24 hours and for some reason I tend to believe this mattress has less off gas than mine. So the sole reason for not giving it a 5 star is because I sleep hot and it isn't the coolest bed I've slept in, but it's uber comfy.
I bought one of these two years ago, paid about 750 for it and in my opinion, I got a heck of a deal. The bed is super comfortable and is comparable to other more expensive mattresses. I spin it about every six months or so and bc its a coil/foam hybrid, it's kept its shape nicely. Everyone who has slept a night in this bed says it's one of the better sleeps they've had. I recommend it.
So far so awesome. I'm a big guy with a serious accumulation of orthopedic issues. Used this to replace a twelve year old top of the line Sealy king size that was keeping both my wife and I up tossing and turning all night. Tried this in a showroom and I was so relaxed in five minutes I almost couldn't get up. It does sleep warmer than a conventional mattress, no doubt about it, BUT, it's a whole lot cooler than the old1st generation foams ( which I found intolerably hot). Super simple pakage shipping makes it a whole lot simpler to handle than a conventional, and we experienced very little if any issues with degassing odors or the foam reaching it's advertised thickness. Due to space issues our two new mattresses were unwrapped and left to reshape standing on their side, which may have actually helped, given the greater surface area exposure and reduced resistance that that orientation allowed. We've now had them (a pair of long twins) for several months and my 110 lb. wife found it too firm, so we replaced hers with something better suited to the princess and the pea and gave hers to our son, and he loves it. We'll see how well it holds up over time, but considering the difference in cost I could replace this every 3-4 years for what we spent on the last Sealy. We did also try probably two dozen similar offerings from the major names and the fanciest Sealy foam mattress was the only one we found that we liked as much or better, just not several thousand dollars better. I consider this proof that you don't have to sell a kidney to get decent night's sleep. Just hope it lasts. We also purchased a pair of the adjustable bed frames with the wired remotes (Pragma) and are equally impressed with them in terms of function and value. The wired remotes are actually a blessing in disguise for folks like me who are constantly losing one. The only caveat is that the twins tend to slide apart on their frames, so I'm working on addressing that (maybe Velcro or a retainer such as is used on the foot of the bed) but overall sleeping better than I have in years.
My wife and I have had this mattress for 3 years now, and it's still great. There is a little bit of a break in now, but it's still very comfortable and not too soft. It doesn't feel like a hammock as a spring mattress would, and it's actually still medium firm. I have back problems, namely lower back spasms, and this has helped me greatly. It works for back and side sleepers (myself) and stomach sleepers (my wife).
I actually bought this from a local vendor in my area. For years I have favored what my family lovingly calls an 'iron slab' for a mattress. I'm a firm supporter of a firm mattress. However, as I get older I got more aches and pains to go with my years and a hard as rock mattress is no longer ideal. But I didn't really want a cloud to sleep on. I cannot remember how I got turned on to memory foam mattresses, but after exhaustive research I surmised which one would be the best, this one wasn't even on my radar. Before buying the one I had selected online, I wanted to test out some memory foam mattresses in the store to make sure that it was possible for them to be comfortable and yet firm enough that I wasn't sinking into them. I went to 5 stores locally, 4 of the stores encouraged me to look at a Sealy, however, the vendor I had gotten my previous mattress from showed me the M Lily. I fell in love with the Lily, but I'm a cautious buyer, so I went home and did some research, and liked what I found. So I bought it two days later. I have had this mattress now for a week and I love it. I won't say that it wasn't an adjustment coming off of a spring mattress, because it was. This mattress is firm, I tried to punch it and it actually hurt my fist. However, the human body is heavy and this mattress will sink a little on the areas where you put the most pressure, namely your butt. LOL. And if you stay in one area for long and warm up I have noticed that the mattress foam seems to get almost 'gooey', however, move from that spot and everything goes back to the way it was. I love the quilted cover, I loved it so much I actually didn't put a fitted sheet on the mattress for the first 5 days. The top layer of foam is some sort of cool gel formula and you can feel it if you run your hand over the quilted top. Altogether, if you like a firm spring mattress than I would recommend this mattress for you.
Just bought one of these here in town. I've literally been in it all night and day it's awesome I weigh close to 300 lbs my wife doesn't feel me get in and out of bed it cushions my weight it's just a great mattress. Even our lil boston terrier loves it lol. Only thing I suggest is make sure buying online like this that you don't lose the 10 year warranty it's great for piece of mind
I bought my daughter this mattress a couple years ago. She loves is so much, I just bought another for my son. He is sleeping very well and loves it, too.
had back pain, headache and tired all the time, and all of it is fixed with this mattress. It offers great support while molding to your body and relieving pressure points. I weigh 240 lbs. Lets hope it lasts a long time
We just bought this mattress about a week ago and we absolutely love it! I was afraid of buying a mattress online so we went to our local furniture store where they had one of these for us to test out. Loved it, bought it, no regrets. It's not too soft not too firm. My husband doesn't like soft beds and I don't like firm beds but we both agree this is the best mattress ever. Also very afordable for what you get.
Bed will not last more than a couple years. Mattress will deform under your body weight until it is virtually impossible to stay on bed. Warranty is a scam. They will not honor the integrity of the mattress.
We were replacing a futon mattress on a day bed in our office/spare room. The futon was so hard it was like sleeping on a stone floor. The new mattress is perfect for me to sleep on when my partner has the flu etc. It has enough support but is similar to our memory foam mattress. When we unpacked it there was a slight smell as it aired but it was minimal and went away quickly. I'm quite happy with this mattress. It's perfect for my day bed. Other reviews have commented on how it bears up over time, obviously I can't speak to that concern.
7'' size is very comfortable: supportive yet soft. Makes my sleeper chair very accommodating, especially for older guests. Arrived quickly; packing odors dissipated within 24 hours.
Excellent product and great delivery service for a bulky product
We had purchased two 10'' Mlily mattresses for our vacation and everyone raves about them. So, when it was time to invest in a mattress for our main home, we thought we'd do the same. After reading dozens of reviews, we went with the 13'' Serenity pillow top model. The first night seemed like a dream. After the first night, my wife and I have experienced nagging lower back pain that can only be caused by the mattress. We are hoping that the mattress softens a bit with time, but so far we are less than completely happy.
Love it it's like sleeping on a cloud best purchase I've made so far
A great mattress, finally found the one!
Very impressed. Had reservations buying a cheaper brand as opposed to Tempurpedic, but the cost savings made it worth the gamble. We've had it for a month now. VERY glad we went this route. The bed is comfortable, sucking you in yet still firm. And the cost savings makes it even more worth it. I would recommend this bed.
It's high quality and makes spring mattresses seems like something dinosaurs would sleep on. If you can imagine being on a distant planet in anothe galaxy sleeping like a boss, this bed is what you'd be sleeping on. Seriously though, it's very supportive yet very comfortable. Stains easy but the lady who sold it to me said any foam mattress needs a waterproof cover. Why the cover isn't washable on this model is anyone's guess. Maybe the makers of the bed thought the buyers for these things were going to be single people that happen to be extremely careful about not having wine in bed...Also, yes, as the other review states, it is very comparable to the mattress at Ashley furniture and such. Maybe more comfy.
Heavenly. The most comfortable mattress I've ever had the privilege of lying on. I replaced my $3k Tempurpedic with the MLily and have slept much better.
I must admit I never would have imagined I would buy a mattress on the Internet without even trying it out first. Well we took a chance, and the whole experience has far surpassed my expectations. My husband and I were disappointed with our local store who carries Mlily. We went there and I liked the Bliss mattress and he thought it was too soft. So we tried out the Energize model and it was too firm for me. So while looking at the Mlily catalog they gave us, we both liked the tranquility mattress and thought that would be a good choice for us. Hybrid , middle of the road firmness, cooling feature and it was one of their higher end models as well as being featured on the cover of the Mlily catalog. Well our local store told us this Tranquility mattress was not available here and was mostly sold in Europe! Really??? Well I immediately looked it up online and found it on here for close to 500 dollars less than the bliss model at the store, with free shipping!!! Now...about the mattress...... It is absolutely wonderful!!! It arrived within 3 days of ordering it and came rolled up nicely in a blue tarp to protect it. We opened it and let it expand for 24 hours.... now keep in mind: I was sleeping on a 19 year old innerspring mattress and I was used to it being very soft, and having the roll to the middle and sink feature lol! Anyway at first I thought it was a bit firm for me, but I have been sleeping on this for almost 2 months and it has softened up just a little and I have been sleeping soundly throughout the night! Its firm but soft if that makes sense. I absolutely love this mattress and would highly recommend it!!! You have lots of support but when you lay down, it conforms to your body without sinking and it just feels dreamy!!! I feel more rested the next day and don't wake up 6 or 7 times throughout the night like I did on our old mattress. The seller we got it from was wonderful too! He went above and beyond to make sure some details were ironed out and helped with us choosing a new foundation for this mattress. We tried out several mattresses locally which were in the 3000 dollar range and this mattress feels just as good if not better than those. I highly recommend this mattress as my husband I have both recieved many positive ramifications as a result of purchasing this mattress:)
We stayed in a hotel suite that had this mattress. We loved it so much we bought one on amazon and it is exceeding our expectations. Love the gel that helps keep the bed feeling cool. The memory foam has great support and doesn't give you the 'sinking' feeling. It conforms to your body very nicely with comfortable support, it doesn't swallow you up. Overall we love this mattress, couldn't be happier.
We have had this mattress for two years. It started off great but not so good now. I wake up around 3:00 am now with my back hurting. The mattress top has gotten loose with the material pooching up. The support is just not there any more. Have slept on other beds (hotels, visiting family, etc) and I sleep well with no back pain. So now I have to put out another chunk of money for another mattress - not an easy thing to do with our income.
Never had any complaints for this bed. Very comfortable and at a great value. Do not pay over 800 for a queen size, otherwise you are getting majorly ripped off.
I have only had this bed for under 30 days but I am so sad I spent $2700 on it. I told the sales person I wanted a bed similar to my ICloud Tempurpedic. I was told this is better than the ICloud. Well, I feel like I am laying in a coffin. The bed sags so bad in the middle and to get out of it is like climbing Mount Everest. I do not have this kind of money to be spending on a mattress. Am so so sad I purchased this product. I would not even sell it to anyone but just take it to the dump.
