Our Full Eight Sleep Mars+ Review 2018

If there is one thing that you learn from this Eight Sleep Mars review, I hope it’s that this is the type of mattress that offers something for everyone. Imagine having a mattress that tracks your sleeping habits. The Mars+ is able to do that. Prior to doing this Eight Sleep Mars+ review, I’d never had the pleasure of trying a smart mattress. I actually thought I was sleeping well. The Mars told me things about my sleep patterns I would not have known otherwise.

The cover, which is where the smart technology is found, is optional. You can buy the mattress without it, but in many ways, it is what makes the mattress unique. You’ll receive daily notifications about the previous night’s sleep. You can learn all kinds of things like how long you achieved a deep sleep, what temperature the mattress was, and the details of the times you woke in the night. These details and more can allow you to determine patterns in your sleep to improve the quality of your sleep. The Mars+ also can pair with other smart features in your home, like the Nest thermostat and other smart home features.

Not all mattresses work for all sleep styles, but the Mars+ is a good option for the majority of positions. It’s a hybrid, so the mix of coils and foam means you’ll have a more supportive mattress that offers all the comfort memory foam can provide.


Eight Sleep Mars Cost and Mattress Models

Composition: How it’s Made

A hybrid design offers all you need for a good night’s sleep.

The Mars is the only Eight Sleep mattress that is 11” thick! Like the other Eight Sleep models, it is made of four layers and a smart cover. This is the only Eight Sleep mattress that’s a hybrid mattress so the construction is a little bit different than you might find in the other models.

Beyond the smart cover, which covers the mattress, things begin with the 2” reactive foam. This foam is great because it offers the bounce you might find in latex. The next 2” layer is made of a comfort transition foam. Next up are the coils. This 4” section of your mattress is surrounded by a polyfoam layer. This is an important layer because it’s going to add a lot of edge support to your mattress. Finally, there is 3” of high density foam, which will act as your foundation and it will add increased levels of support.

As this is a foam mattress, you may find that you sink into place faster than in some mattresses. Despite that, the mattress offers a good bounce back and it’s easy to move around on. You won’t sink to the point of getting stuck.

If temperature is a concern, you should know that the Mars+ sleeps relatively cool. This is likely because the coils give the mattress room to circulate air, making it a good choice for those looking for a cooling mattress. That said, thanks to your smart mattress features you can control the temperature of your mattress so if you find it too warm just adjust the temperature and you’ll be good to go in minutes.


How Comfortable is an Eight Sleep Mars+ Mattress?

Breathable, cool, and supportive this hybrid mattress has it all!

Two of the most important things when it comes to any mattress is knowing what your mattress is made of and knowing that it will provide you the comfort that you need to rest easy when you sleep. Earlier in this Eight Sleep Mars review you learned about what each mattress is made of, so now let’s consider the comfort level. It’s worth pointing out that thanks to the hybrid nature of the mattress, this is a mattress that will appeal to more people. It will be suitable for both thin and heavier people and people that sleep in the most common positions. In short, whether you’re big or small or sleep on your side or back, the Mars could be for you!

  • Firmness: The Mars+ is a medium on the firmness scale. It’s not the firmest Eight Sleep mattress and it’s not the softest either. That said, it is incredibly comfortable. It’s good to have a mattress that offers a bit of both softness and firmness as it will appeal to more people. This is one of the reasons that the Mars is good for most any sleep position.
  • Sinkage: Thanks to the coil construction and the foam that encases them, not too much sinkage occurs with the Mars. In fact, this is a great option for heavier sleepers because of this. The coils provide more support, and that ensures the mattress can hold more weight. So, no more deep sinking in your mattress.
  • Motion Transfer: There aren’t any complaints in this area. The mix of coils and foam seem to help limit the motion transfer. You won’t feel your partner tossing and turning in bed and if they get up before you, it’s likely that you won’t even notice they’ve gotten up! Overall, it’s a solid mattress for couples.

“Mattress Magic”: Is Eight Sleep Mars+ a Good Bed for Sex?

The top layer of foam provides a responsive bounce that will come in handy.

One of many factors when buying a new mattress is how good it will be when it comes to sex. If it’s too hard it might not be comfortable, but if it’s too soft you might feel like you’re sinking and won’t be able to get out of any position easily. Luckily, the Mars is a hybrid mattress that’s medium firm. The springs provide some bounce along with a responsive top layer that also brings the bounce. This allows you to move easier and does not hinder your ability to change positions.
