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!
Sherwood Bedding Group makes a variety of mattress brands including Sherwood Bedding, Lumina, and Encore that are innerspring, pocketed coil, and hybrid mattresses. They also make Evosleep and Dunlopillo, which are memory foam and latex options. You may find these mattresses in local retailers such as Mattress Firm. Folks describe them as comfy in store, but may experience durability issues once at home.
Based on our aggregated reviews and our scoring method, we recommend Eight in this match up!

Sleepers report feeling very comfortable and satisfied with these mattresses, which means that based off of recent and overall customer sentiment these mattresses have great percentages of positive feedback. This is a great place to start in figuring out if one of these mattresses will fit your needs -- read on for more specifics.
These mattresses are well-rated in their supportiveness. Sleepers report feeling that their hips and shoulders are supported while their spine is aligned properly.
These mattresses also keep things competitive in regards to edge support, which is the supportiveness of a mattress on its sides. For people that like to sit or lay close to the edge of the mattress, these mattresses will do a good job being supportive to your body.
Bowling Ball & Density Tests
A bowling ball can be used as a good indicator of firmness, and it can also provide guidance on the difference of firmness throughout the mattress. Therefore, it can show if there is even resistance or if some areas sag. These mattresses are even and should do well supporting the spine of most sleepers.
It's difficult to find products that last a long time these days. Brands, by and large, go after profits first rather than building something that lasts forever. However, there are still great products to be found. These mattresses provide a very good element of durability to most sleepers. They should last up to a decade for many sleepers, though some who are on the heavier side may experience them to falter a bit sooner.

Some sleepers are comfortable with their new beds, but others were not as satisfied with how the mattress made them feel. Despite those that are happy with their selection, this brand has lower satisfaction scores than average. Read on if you are considering buying for more information on the mattresses.
Support isn't exactly the same as firmness. Support is great if it aligns the spine and leads to a healthy night's sleep. Sadly, these mattresses have some mixed reviews when it comes to support. Most customers are comfortable with the support right after purchase, but some folks felt like support was lacking over the long term.
For those that like to sit on the side of their bed, even edge support is essential. For most, these mattresses do a good job with edge support, but some may find that it changes over time.
Getting a mattress which has lasting comfort is what buyers are after. We all are hopeful our mattress will last a decade or more and stay just as cozy as day one. That said, not all customers rate these mattresses very well on durability and some have had issues over only a short horizon. If you are considering purchasing as your full time mattress, read the reviews to make sure it will work with your body before buying.
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.
This is such a great mattress. We found it at the local mattress firm and couldn't be more pleased.View More Reviews
The mattress felt excellent in the store, but once we slept on it for a month it started to cause back pain. I am hoping it is just an adjustment period, but afraid if it isn't.
This mattress was great in store. But after we got it home, it started to sag within weeks. After a few months, it is starting to affect my sleep because me and my husband are tossing and turning all night long. What a disappointment.
We got the Oasis Resort and within the first year it had completely deteriorated. Massive sagging issues and big lump in the middle. This is not what we wanted and now we are stuck with it because our warranty claim was denied.
We bought a $1400 Sherwood mattress and after 4 years, it was sagging so much I woke with a back ache. Went back to the store and they said they no longer carried this brand because customers were unhappy. Contacted Sherwood and their 20 year warranty was meaningless because they determined it was just fine. More money DOES NOT mean quality.
When we first got the Sherwood Oasis mattress in 2013 the first 2 yrs it was a good comfortable mattress we were happy with. After year 2 it began sagging in the center and by year 5 it had to be replaced
