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!
Sapira by Leesa is a hybrid in a box offering with pocketed coils and layers of memory and poly foam on the surface-comfort layers. Offering a more luxury feel than the Leesa, the Sapira comes with a higher price point and exclusive brand experience. Based on the firmness specifications, the Sapira should help at straightening the spine for back and stomach sleepers, but others (especially side sleepers) note that it is too firm for them. Overall, there is a lot going for the Sapira and with a generous trial, you should feel comfortable testing it out!
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.
Comfortable and easy purchase. Very satisfiedView More Reviews
The bed is very firm. I have to admit I no longer have my back pain. However, I am a side sleeper and have hip pain on this mattress which causes me to toss and turn.
You slowly sink in.....lights out.....it's all paid for! :-)
Really like my Sapira king.
Combo of spring and foam is perfect blend of technologies.
Vacuum packed shipping enabled getting this king up my stairwell (that could not be accomplished with a conventional spring king).
Never realized what I was missing and the positive very real impact to minimizing body pain - I didn’t realize it was my mattress!
Will always have this product in future rooms I furnish and/or recommendations to friends.
Do recommend a few days for offgasing smell of preshly unpacked box
My old mattress was starting to sag and I had back pain in the morning. A few nights on this, and I was as good as new!! Really loving the firmness to comfort ratio. I would definitely recommend this to anyone looking for a firm yet comfortable mattress.
Soft but firm, good quality mattress. Only knock on it is the chemical smell from the materials off-gassing. The smell gradually goes away, just like a new car.
I tried the Leesa and it felt too dead to me; no life, no bounce. The Sapira solved those problems for me. I like that it is soft and springy but still supportive. It's also thicker and the springiness helps propel me out of bed in the morning when my knees don't want to. I really like this mattress and I'm happy I got it.
This mattress was everything I hoped for in comfort. Wife and I are very happy.
So far we have been happy with our new bed. We are both side sleepers and the bed is quite comfortable. Prior to this mattress I couldn’t stand to sleep on my side, my hips really hurt. We hope that the bed continues to feel comfortable going forward!
We’ve been sleeping great! Delivery was fast and set up was easy. Love it!
Sleeping like a dream!
After reading the reviews, I was skeptical like many others of purchasing online. I read a review about an individual who used to sleep on an I-Comfort like we did and described it as sleeping on a warm gummy bear which could not be a more apt description. For three years my wife and I were uncomfortable and unhappy with our warm gummy bear, but after spending 3k on a mattress it is hard to let it go. Now all we want is to climb into bed. The mattress is definitely more firm, but supportive. We sleep like a dream. If you are unsure, give it a try. You will not be disappointed. Back feels great, you wake up refreshed, it is not a hot sleep, and it is a perfect combination between the coils and the foam. Best mattress we have ever had. Looking forward to actually sleeping for years to come.
Getting used to it. My hips feel great, but at times it's a little firm for my shoulders since I ama side sleeper. The leesa regular matress w as good for my shoulders, but too soft for my hips.
This mattress is FIRM, but not hard. Offers great support for the whole body. My wife and have been trying out new mattresses for the better part of a year and finally found one that we’ll be keeping. Thanks, Leesa.
Perfect firmness and comfort. Delivery was fast and easy. The box did weigh a little over 100 pounds though. I like everything about this mattress except the initial chemical smell. Fortunately, the odor disappeared completely after about 30 days. I recommend letting the mattress sit for a few days without sheets to speed up the outgassing process.
We love it! Great improvement over 10 year old Tempurpedic
Love this mattress... just the right firmness
I am no expert on mattresses, but I have spent time comparing prices on mattress and this seemed to be the best for the price. At first it took some getting used to. Now I don't want to get out of bed anymore when the morning comes. My body aches much less than before. If i were alone I might have got the Leesa over the Sapira, but I wanted the extra support on the edge of the mattress. Worth every penny.
This is the best sleep I've ever had. I loved the product so much, I returned the Queen size for a California King. Leesa support was excellent through every step of my exchange and really went the extra mile for me to have my new bed before my old one was removed. Highly recommended!
I have friends and family that think that it is too soft. For years i've slept on a firmer memory foam mattress and thought it was fine but I was always hot. My first impression (really, no pun intended), was that it was indeed too soft but what lured me to take the challenge was the 100 night gaurantee and the claims of cooler sleeping conditions. It is indeed on the soft side but I feel that this and it's built in coolness allow (encourage?) me to stay in one place. I just moved so I am super busy and not giving my back the attention it needs, yet, my back feels better than expected.
Love this mattress and was absolutely amazed how it came via UPS in a box. It made getting it in the house so easy! Highly recommend!
We considered all the available ship-in-box mattresses and went with Leesa based on the good reviews, and simple ordering process (having only 1 style mattress). We are super pleased with the result! A comfortable, not to firm not to soft, mattress.
I used to wake up a couple times during the night on another online memory foam mattress that I tried, but now I don’t wake up at all during the night!!
Wondering about permanent body impression/dip... we will see..
Love my Sapira mattress ! We had a pillow top mattress that sent you to the middle I’ll never have anything but a sapira again no more rolling to the middle also we went from a gueen bed to a king (even better) they are a firmer mattress but the more you sleep on it the more you get use to it and I recommend it highly . Also the convenience of having it delivered and easy setup.
its just okay, i don't think my mattress is leveled properly
The firm mattress is extra firm. Probably should have order the regular. Seems to be a good product but overpriced.
The best ever mattress with a convenient purchase and set up experience. My husband and I are finally experiencing a full nights rest which we have not had in years!
I had a Casper mattress before this one. I felt like the Casper lacked a bit of cushion on top. I don’t feel this way about this mattress. It’s the perfect firmness and cushion.
Great bed. Best test in years
This bed exceeded our expectations. It feels so still and relaxing. No springy feeling or sinking feeling. Overall comfort. Highly recommend.
I loved the leesa but the sapira is even better!
Thanks to some thoughtful YouTube reviews, I decided the bed-in-a-box that would probably work best for me was the Leesa. I could not have asked for a better mattress; It’s supportive and so very comfortable. I look forward to sleeping in it every night, and if I’m lucky enough to have the time in the morning, I just like to lie in it and revel in how it feels. The mattress I had before was a traditional spring mattress with a pillow top, but it was far too soft and caused severe discomfort in my hips and joints every day; my husband and I hated that thing but felt bad about throwing it out before having owned it for ten years. Just sitting down on the Leesa to put on or take off my shoes is a pleasure. We’ve had it for a month and-a-half now, and I’m confident it will not disappoint for years to come. Our previous mattress became a nightmare just after a few days! I highly, highly recommend it to anyone looking for a firmer mattress with just the right amount of cushioning support.
We liked it, but we also ordered a Nest and thought it was a comfortable and was cheaper and this was for a guest bed...so we are returning it. Thanks.
If you like a soft but firm mattress, you'll love it, but coming from 20 years on a waterbed, it's too firm for us.
Unfortunately I had to return the mattress due to being too firm for my situation. I sleep on my side and have had rotator cuff surgery. The mattress had a luxurious feel, seemed well made and slept cool. Just a bit too firm for my bad shoulders. The return process went great.
The matteress feels wonderful. Took me about 1 week yo get use to it. Guess I’m just shocked that I could buy a mattress that feels that good for that price and one that comes in a box. Will I still feel this same way in 1 year or 5 years from now......we will see.
