Eight Sleep Review

The Eight Smart Mattress is a 4 layer foam mattress with a nice medium feel, great pressure relief and support. What is unique is their smart cover that slips over the mattress and connects to your phone. The cover tracks your sleep, warms each side of the bed and has several other unique features!

See the full Eight Smart Mattress review below.

You Will Like the Eight Smart Mattress if You:

  • Want a good value – Eight utilizes the direct to consumer model so you can save some money there!
  • Like to sleep cool – The 2″ Reactive foam has the consistency and makeup close to that of latex foam & did not get excessively hot for us at all. Kayla is typically always cold so heat was not an issue for her either.
  • Are someone who values bounce and body conformance for great pressure relief – Eight has a good amount of bounce on top so you don’t feel stuck and the right amount of body hug to help relief pressure points.
  • Are looking for a mattress to fit all sleeping positions – Bear is a good medium feel and it performed well for all of our sleeping position tests.
  • Are considering a sleep tracker – The sleep tracker smart cover is a great add on to turn your mattress into a smart mattress! The heating on each side is a feature we really like. The tracker can be used on other mattresses too!

You Might Not Like the Eight Smart Mattress if You:

  • Want a super soft mattress – Eight is a medium feel. If you prefer an extra soft mattress you will want to look elsewhere. Or extra firm.
  • Don’t like foam mattresses – If you are a spring mattress lover you may want to consider something with coils.
  • Are a heavier sleeper – I usually recommend mattresses more than 10″ thick if you are over 300lbs.

Eight Sleep Construction

  • Top layer (cooling & comfort) – 2″ of reactive poly foam. The top layer offers both the cooling and initial level of comfort for the sleeper.
  • 2nd layer – 2″ of memory foam.
  • 3rd layer – 2″ transition foam.
  • Bottom layer (foundational) – 4″ high density support foam. This layer has a density of 1.8 PCF.

His and Hers – Firmness and Feel:

My Thoughts (Ross)

The Eight Mattress impressed me for the following reasons.

A.) It has good pressure relief without giving you a stuck sinking feeling.

B.) The top comfort layer really didn’t get hot and had good bounce.

C.) It worked well in all sleeping positions.

D.) The sleep tracker is great. I can keep the heat down and Kayla can warm up her side of the mattress. Its also been fun to see how well we sleep, when I’m waking up etc.

Her Thoughts (Kayla)

For me the Eight Mattress had a good medium feel. It conformed well even though I am light but still had good support for Ross who is heavier. The overall feel of the Eight was nice, the top layer is easy to push into even being lighter so it conforms well with little weight pushing down than some memory foams we have tested.

The smart cover is amazing. Like Ross said I can warm up my side and its toasty and cozy the time I get into bed. Its all set with the app! The smart alarm has been great too, it starts quieter and gradually wakes you up, it seriously makes a difference in how my mood is waking up. We don’t have any other smart home products but we want to get a thermostat to connect to the mattress.

Temperature:

The Eight Mattress performed well for temperature regulation. The memory foam in this mattress is buried a layer down and the top layer of foam did not trap heat hardly at all. If you are someone who sleeps extremely warm you should not have a big issue here with temp.

Adjustable Base Performance:

The Eight Mattress will work great on an adjustable base. We reviewed this in king so we didn’t show a video on our base. Being all foam it will work like a charm however.

Overall Summary

Eight Mattress is a great medium option for those of you who sleep in multiple positions. The mattress slept cool and with the direct to consumer pricing they also are a good value. Overall we really liked the feel & performance of the mattress. The sleep tracker we are still using and we love it. From the heating to the smart alarm its great. The sleep tracking has been fun to see as well.

4.6
5/5

Tracking how much I exercise vs. how much better I sleep has been a motivation for me as well. We recommend the Eight to anyone looking for a medium feel foam mattress & the tracker to anyone looking for a sleep tracker, bed warming or to any techie out there!.
