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!
Hyphen, like many others, offers just one mattress designed to fit everyone's needs. This mattress is made of three layers of foam -- polyurethane on top, transition in the middle, and support on the bottom. What it offers hand-down is relief on pressure points, which is excellent for those with constant pain.
Based on our aggregated reviews and our scoring method, we recommend Eight in this match up!

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.
One of the best mattress I have ever slept on.View More Reviews
It doesn’t gas and it stays cool! Perfect for me husband and myself!
I have had the Hyphen for over a month now and I can't relay to anyone how happy I am with it in a review. It's just a fantastic bed. Period.
Feels great and takes some getting use to but overall very happy.
Stays cold, even with multiple sheets covering it. Super comfortable and relaxing, no longer twisting and turning for that perfect spot.. Transformed my night!
My husband had been noticing on his sleep tracking device a severe lack of deep sleep. He would get an average of 30-45 minutes a night. After trying out various mattresses in stores and doing a lot of research online to find the right mattress, we found Hyphen. We've been sleeping on our very own Hyphen mattress for about 6 months and we absolutely love it! I sleep through the night (mostly, I am a mom) and my husband's sleep tracker consistently shows at least 2 hours of deep sleep.
I was hesitant to purchase a mattress online, but we decided to give it a go because of hyphens return policy. My fiancé and I are so happy we purchased this mattress. The foam contours to my body well and I no longer wake up with pain in my lower back. This mattress is the perfect medium firmness and sleeps cool. The best part... there is little to no motion transfer. I am a very light sleeper and I hardly feel when my fiancé gets into and out of bed or tosses and turns during the night. It is incredible! We love our new mattress! My parents just ordered a hyphen mattress for themselves after testing out our bed.
I've never purchased a mattress online but since I was moving and didn't have the means to transport something large this made sense. Quick delivery and packaged well this mattress isnt soft but isn't too firm. I definitely would recommend this mattress for anyone in any situation.
My husband researched mattresses and this was his recommendation. Delivery and set up were very easy (though because the box is large--we ordered a queen mattress--I would recommend two people to help move the box, especially up stairs). I did not notice any smell once I unwrapped the mattress. We placed our mattress on our existing box spring, which has worked well. It took a couple of days to get used to the mattress, but since I have slept well. (We have had our mattress for just under a month.)
My husband and I bought the King size mattress about 5 weeks ago. When we opened the plastic, within minutes it it was ready to lay on. There was no oder at all! We also purchased the mattress protector. My husband prefers a firm mattress and sleeps on his side. I like a softer mattress and sleep on my back. I researched for weeks reading hundreds of reviews from all different companies. We have always gone to mattress stores in the past and we were over it! We have spent a lot money over the years, from the traditional spring, to foam and also Select Comfort air mattress. We wanted to move from a Q to a K bed. I loved that you can sleep on the Hyphen for 90 nights. That was huge to us! We also don’t feel each other moving around or getting up which is nice. So far we like the mattress. We are happy we have the 90 nights to really get the feel for it.
We've had our mattress for a few weeks now and really like it. Would definitely recommend it.
It was super easy to set it up and so far it's been very comfy. We're happy with our new mattress.
I am a 6'6", 275 pound person who sleeps on their side and no store-bought mattress I have owned compares to the comfort provided by the Hyphen. 10/10 would recommend to anyone looking for a comfortable, sturdy mattress.
Love it!! Comfy and well made! And attractive..fit the platform bed I ordered perfectly!!!!
Very good mattress.
My fiancé and I had been sleeping on a busted old mattress for way to long, we had visited a few mattress stores with hopes of buying a new but the prices were just too high. After sleeping on my sisters Hyphen mattress, I decided to buy one! With a little holiday promo code, the price was right! The mattress is insanely comfortable - firm but soft. Who knew we'd be able to sleep so well again! We couldn't be happier!
I saw a few reviews that said to give yourself a few nights to get used to it but my boyfriend and I loved it right away! It's so comfortable and has kept me much cooler than our regular mattress this summer. Awesome value for the price! I live in Alaska and I absolutely appreciate that Hyphen even ships up here, nevertheless does it for free.
I have had some very expensive mattress' in the past but this one is great. Have had it almost a month now and my back is much better, no kinks, pain and I am walking with a straighter back. :)
We purchased this mattress to replace a very thin, very uncomfortable hospital bed mattress. Initial concern was that the Hyphen mattress would be too thick for the adjustable positions. After unpacking and allowing the bed to expand we tried the head and foot adjustments. The head raised up to my sleeping position with no trouble. The foot/leg adjustment didn't work so well without a body actually in the bed as the mattress stayed flat and shifted upward. But once you put weight on the mattress the adjustments worked well. This bed is very comfortable. It also did not sleep "hot". However, we had to put a mattress cover on the bed because we were afraid it might get stained. So the plastic mattress cover causes its own heat reflection. After one week of use I give this bed a five star rating.
It's been a month and my husband and I love our Hyphen mattress. It's firm enough that we don't feel each other move in the night but soft enough to relieve any pressure points. Couldn't be happier.
But I am a believer. I did have to put a cooling mattress pad on the top, as it did get me rather warm a few nights, but other than that I am enjoying my new mattress. And I'm still in the 100 day test period.
My husband and I wanted a mattress to go with our adjustable frame and this is perfect. I prefer a firmer mattress and for foam, I think this is about as good as it gets. We laid on a lot of mattresses and we are happy we chose Hyphen.
The new Hyphen mattress is so comfortable! Both my husband and I had a great night’s sleep. No pressure points causing discomfort; no sagging on the edge. Definitely a great buy - thanks!
Enjoying the KING- SIZE comfortable - luxurios NEW Hyphen with 20 yr guanantee .....;))
Outstanding value. I was skeptical to purchase an online mattress but took the leap with the return policy. Very comfortable mattress and exceeded my expectations.
A friend got a Hyphen and loved it, so we went to check out his mattress. It felt great, so, after dithering about buying a mattress online, I ordered. In about a week, a big, heavy box (with very helpful handles) arrived. It's not hard to muscle the rolled-up mattress out of the box and onto the box spring (I kept my old box springs, because I like a higher bed). And then the magical inflation happens (sadly, there's no satisfying inflation noise...I was hoping there would be). And then you have THE most comfortable bed. It's firm with cushion on top, is the best way I can describe it. You're supported in any position - it forms to the parts of you touching it - but doesn't leave a print behind when you move. It's not noisy -- by which I mean, when my boyfriend turns over, I don't feel it. (Also, when my cats jump up, I don't know they're there, which has taken a bit of adjustment on my part.) Two things I've noticed: there's definitely softness at the edges, so if you sit right on the edge, you feel like you might slide off. Move back 2 inches and it's all good. I also feel like it runs a little warmer than my old mattress. It's not unpleasant, and it doesn't get hot, but it's definitely warmer. I'd really recommend this mattress to people who like a firm-with-some-give mattress.
It's so much better than my last bed. Very comfortable. Helps me get to sleep faster and stay asleep longer.
This mattress if just firm enough for my 210lb frame. I don't sink into it al all and can move rather easily which is not typically the case with memory foam toppers. A full memory foam mattress is wonderful.
Bed is awesome
Same high quality as the mattress. Very comfortable.
I like the mattress, the way it looks, the way it feels. I had a good night sleep.
I was a sceptic at first but decided to give the Hyphen Mattress a try and I find the mattress very comfortable! It really does provide great relief to the usual pressure points & feels like you are floating.
We purchased this for our guest room and an incredible buy for the price. We have a posturepedic mattress in our master that I do like better, but it was 4x the price. The Hyphen mattress is a perfect balance of comfort & value - and when it is time to replace the mattress in our master, we will likely choose the Hyphen.
Excellent product and I exceptional &a speedy service.
We are loving our new Hyphen mattress. My back and neck no longer hurt when I get up in the morning. I can feel my entire body being supported, and it is not the least bit hot. I am so glad we bought this mattress!
I was skeptical at first to purchase a bed online, but have never looked back since. The bed is constructed of high quality materials and I trust in its durability given the lengthy warranty and the fact this mattress is made by a reputable SoCal bed manufacturer. During my first week of sleep on the mattress I have noticed I am sleeping cooler and waking very little during the night (confirmed by sleep tracker I wear). My wife has also expressed great support and give balance since she is a side sleeper; I sleep on my back. Everything about this bed reminds me of more expensive latex beds, exactly what I was looking for. A bed that doesn't sink, but has the support of latex/foam and sleeps cool. My only knock on this bed is support at the edges is weak, but per reviews, this seems to be an issue with many memory foam and latex beds. Finally, if you are seeking a true memory foam bed that sleeps hot and conforms to your body due to sinkage, this is NOT the bed for you. You will feel some very light motion from your partner, but that is to be expected if you have a highly responsive bed. Overall I am very satisfied with this purchase and look forward to the bed continuing to break-in with use.
very pleased so far, but may purchase a pillow top for little more comfort
