The Eight Mattress is a Y Combinator backed start up that was first known for its smart mattress cover. With its initial success, in late 2016, Eight announced that it would create its very own smart mattress. They are one of the first companies to this space and some sleepers report that there are still some mechanics to work out. However, the promise of their product is remarkable: bed warming, smart alarm (that wakes you at your lightest sleep level), an integrated mobile app, and further customizations with your smart home.

Eight's Specifics

Quality of Materials

The Eight mattress comes in both 'The Smart Mattress' and 'The Eight Mattress.' The only difference is that the Smart mattress has its technology layer that connects to a mobile app to control temperature, see sleep trends, and more. Here is what's provides the comfort:

Layer 1: 2'' reactive foam that provides a nice element of response without that sinking feeling.

Layer 2: 2'' of memory foam that relieves pressure points and softness to the surface.

Layer 3: 2'' of transitional foam that provides additional pressure relief from the base layer.

Layer 4: 4'' of base support foam that gives the bed base.

Overall Comfort

Most agree that this mattress provides a good amount of comfort for the average sleeper. Beware that some have complained about heat retention.


Eight's mattress is rated as a medium firmness bed. Based on the specifications, some heavier sleepers may feel like they are sinking.

Back Pain Relief

For most light and medium build sleepers, this bed should provide back pain relief.


Some have complained about heat retention. If you are sensitive to heat, this may be something to keep in mind as the Smart Mattress does not currently have a cooling temperature control option.

Who Is It Good For?

For those that love the newest technology, are medium to light in build, and are not warm sleepers.

Very cool bed

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.

Happy with my purchase

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!

Sleeping so much better

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.

Getting good sleep!

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.

I was sold!

If the Eight lives up to the website, I'll be in sleep heaven.

Interesting bed -- not sure it is for me

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.

Good stuff

The site was very easy to use and the purchase process was very straight forward

Simple experience

Product says it all and I hope it is as good as the hype.

Good mattress

The Eight Sleep Mattress brings a solid mattress and intriguing technology layer to the table.

Solid bed -- tech needs time

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.

Exactly what I wanted

This is a great bed -- I am really happy that I decided to try something new.

Great mattress for two

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.

Highly satisfied

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!
