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!
Sleepy's Mattress is a wholly owned Mattress Firm brand and mattress in a box offering for a very competitive price. Their offerings include foam, innerspring, and encased coil. With multiple firmness options, they have something for everyone, and even have both an online shopping option. That said, there are some complaints about durability and craftsmanship.
Based on our aggregated reviews and our scoring method, we recommend Eight in this match up!

Solid support throughout a mattress is essential to its feel and whether it provides health benefits to the spine. These mattresses offer a good supportive surface to sleep on for most sleepers. So, you can rest easy that these mattresses will support your back while you sleep.
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 will prop most sleepers up rather than sinking.

There were mixed feelings about these mattresses. Many folks describe feeling comfortable on their new mattresses and sleeping better than before, but there were others that didn't feel as positively. Make sure to read on for more information on if one of these mattresses will work for you.
These mattresses have above average ratings for support, which is ideal for those that are struggling with pain from a sagging mattress. However, there are some that have mentioned support and feel issues, so make sure to figure out if the firmness and overall specifications are for you.
Edge support is the amount of resistance there is for sleepers along the side of the mattress. These mattresses offer good supportiveness for most, but heavier folks may experience some contouring.
Mattresses don't last as long as they once did. A mattress that continues to stay comfortable after 15 years is becoming rarer and rarer. Yet, finding that diamond in the rough can save you lots of money. Unfortunately, customers give these mattresses mixed reviews on durability. Many folks report no problems with durability, but others have comfort longevity issues on a faster time frame than is usual.
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.
Purchased Sleepys king size over a month ago. I have never had a more consistent quality sleep. I work a lot and have soreness in my back and legs (not injury pains) and used to only sleep around 5 1/2 - 6 hours a night. I sleep soundly now with the Sleepys mattress. I would recommend this to any and everyone that's looking for a new mattress. First time I've slept past 9am in many years.View More Reviews
I bought this mattress 3 weeks ago and I have Fibromyalgia, arthritis, severe back pain, chronic pain for the last 18 years. Every mattress I had before caused some sort of pain, even with memory foam mattress toppers. I decided to try the Sleepy's Essential 8" Memory foam mattress and I'm so happy I did, I'm SO pleased with this mattress!!! it doesnt make you feel hot and it doesnt sag when you lay down on it; is a firm feel but its very comfortable. The first night I slept on this mattress I slept through the night and that is something I could never so before. My sleep is so much better since I purchased this mattress and I recommend this to any one who suffers from back pain or similar problems that I have. It was worth every cent I paid for it! Thank you so much Mattress Firm!
I purchased this mattress and have been satisfied ever since. I love the feeling of sleeping on a firm mattress with a little cushion so this was perfect. I liked sleeping on the floor as a child because of the firmness, now I have comfort and firmness.
I was surprised when they delivered it how it was compressed , After 2 hours of expanding it was ready to try in the comfort of our own home . It sits a lot lower than on the old matters ( felt like you would fall off a mountain with that one ) So far a delight to sleep on an we picked it out ourselves .
Sleeping so much better. Happy to have a great mattress.
I slept on this for about 2 wk and a half. First 2 wk smelled, so I tried to air it out the first couple of days by taking off the cover/ wash/ keep upright w/ windows open, ventilate etc. After 2wk the smell is alright. I like mine firm, so this one is okay. I prefer slightly more firm but overall this one is alright.
Bought it for my son, he is very happy with it and sleeps well at night.
The price quality and service can't be beat great job Mattress Firm
I brought this for my I Uncle who has mobility issues. After he got use to it, he was able to get in and out without any problem.
I received my bed on Jan. 25th, 2018 and it's just absolutely great.
Is firm firm firm I love it!!! Just like I expected thank you so much
My first night on this amazing mattress. I love my bed.
Bed is soft but does not return to it's original position well. I've been sleeping on one side and after about a week or two there is a noticeable difference in height between the side I sleep on and the other one.
I sleep so well on this mattress and that’s what count. Love this, love love love!
My wife and I live the new mattress and the price was right...thank you
I’m very happy with my new Bed! The pillow top is great balance between plush and firm mattress!!
Just got our bed today and i love it my wife and i both have bad backs and its perfect
This is the best mattress, hands down!! I did a lot of research and took a lot of different quizzes to figure out what kind of mattress works best for me, and this one came out on top. I have back problems and since I got this mattress last week, I haven't been any! It is plush yet firm and oh so comfortable. I also bought a mattress pad that has made sleeping so good. I 100% recommend this mattress to anyone and everyone!
I bought this mattress on 5/14/18 for $249.00 and I hate it! It is as stiff as a board and makes so much noise that even when the dog moves, It rests on a very expensive box spring that has never creaked before. I cannot exchange it without incurring another $100.00 fee. I have a back and neck ache that I did not have before sleeping on this horrible product.
My dad bought this mattress for my younger brother. He is very tall and is very active, he loves it! It's so supportive, not too firm or too soft, and very comfortable! I am surprised at how great the quality is for the price.
This is the first time i have bought this kind a Mattress, I had my doubts since my youngest daughter have one like this, i have two back surgery’s my doctor recommended me a firm mattress and said this is garbage mattress i said let me try it. I can’t be more happy! I got ut with the adjustable base, the best purchase ever. 5 days and 25more to go for. Since it takes 30days for your body to get used to a new bed.
The store clerk said we would not regret it if we went with our first choice on a firmer option. The queen arrived in a skinny rectangular box that we thought was the frame because it was so compact. Amazingly, over the next hour, it transformed from a pancake into a thick and luxurious mattress. We got the protective casing which makes me feel 10x better during everyday use that we will never have a problem with our warranty. So far, the bed is exactly what I wanted. When I go to sleep, I have a tremendous amount of support with enough give to make an indent where my body naturally curves. I'm about 125lb, and my husband is about 225. He says his indents do not as quickly rise when he changes positions, so it takes a minute until his side of the bed fills back in. It's only been a month, but I have confidence we are going to love and keep this bed for many years. I highly recommend the base with the header and footer rise. We always sleep with it flat, but the few minutes in an elevated foot/head position really relieve back tension. Thanks for a high quality product!! The bed is also beautifully stitched. I would come back. The deals at mattress firm are competitive for the quality you receive.
I am sleeping so much better, it is cooler I am not turning as much , I find my self wanting to get in bed n useing the feet n head posture in stead of siting up in frount of the T v in family room get to to work on my I pad ,
We slept on this bed for over two months and it just did not soften up as much as we had hoped, really barely at all. It is a very firm mattress but is still comfortable to sleep on though it just causes back pain for me and my partner. The cooling is great but make sure you have breathable sheets or it will be just as hot as any other bed. If you are looking for a firm memory foam this is great, just dont expect it to get much softer than what you get the first day.
bought this weeks ago and now my son is getting a good nights sleep
I have had this mattress for a few weeks ago and I am glad I went with the Sleepy's cool. It is a bit on the firmer side but this is what I like. For the price you can not go wrong. They had a special and I got a free adjustable frame with my purchase and I could not be more pleased.
I’ve been sleeping on the twin version of this mattress exclusively since it was delivered on 4/23/18. Some background: I had been experiencing a lot of morning mid-back and rib pain on my old mattress, and was not sleeping well. I am a mid-50s insomniac woman. I tried several models in the store, including Tulo and Serta iComfort memory foam, and chose this one due to its thickness, beefy feel and comfort during the 15 minutes or so of testing. Although it felt firmer than my preference, I figured it would be a good option for my back pain, and I decided to give it a try. I did not think to purchase a new foundation (“box spring”) at the time.
I just purchased in store 3 days ago and I love the cool mattress temperature and the fact of it having no springs. It's plush firm like cuddles your body I have a knee injury and in the last 3 days of sleeping on this my knee has felt better.also I don't need a bunch of pillows anymore my back feels great .. I will never go back to springs. This is a great mattress Try it...
I bought this mattress a week ago. I have had Simmons and Serra inter-spring beds up until now. We tried it in the showroom and were hesitant as it was very firm but since it sort of confirmed to our body and the price was right we thought we would give it a try. I can say now that it is taking us a bit to get used to this type of bed but are overall very happy with it and are confident that over time it will soften up a bit. It is a well constructed bd and we are happy with our purchase
I am so pleased with this mattress the best thing I like about it is that it is so solid that you can't feel the next person moving on the bed when they toss and turn or get up or lay down it's very comfortable and just what I needed
I bought this a couple months ago and love it! I sleep through the night!
Have slept in this mattress for 5 nights and was hoping I would get used to the firmness but unfortunately neither my husband or I sleep well in it. My children had a foam mattress and love it so we thought we would give it a try in our new beach condo. They obviously purchased something softer because this is extremely firm. Wake up each morning with a back ache. Going to call about exchanging it.
We exchanged a tulo for this mattress and were very satisfied. My wife sleeps better that she has for years. thank you.
I'm very happy with my purchase, the service and everything was great! I wouldn't trade my mattress for anything, and at unbelievable, affordable price, highly recommend them!
I love my new mattress couldnt be happier only if i could stay in bed longer
We bought our mattress a month ago and it was our best purchase ever. Can't wait to climb in bed every night. No aches or pains ever since our mattress was delivered. We give it a 5 star rating.
I had this mattress for about a month and although I love the feel of the mattress it seems hotter than a normalization
Value was important to us and this mattress was a great purchase.
You wouldn't think it but my old mattress was killing me! After one night of sleep on this mattress my left shoulder and back had no pain. Which hasn't been the case for almost a year. I thought I was just getting old turns out is was my bed! Sleepy's cool mattress me and my wife thank you its been over a month and we can't say enough to thank you for such a great Mattress and for relieving what felt like years of pain. I do have one question for you do you make pillows?
Too early to tell ... so far I like it. No recommendations yet.
