Get Best Mattress - Chris Young

coils as a bottom layer and shows improved motion isolation ability. Reasonably priced, the Mars mattress will not disappoint for sure. Read full review

Real Mattress Review - Ross Paumen

Eight Hybrid 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. I like the floating on top feeling this provides vs a sinking/stuck feeling. Read full review

The Sleep Sherpa - Ben Trapskin

a great way to get some objective data on how you sleep. Once it is setup, it is effortless. While the mattress itself should appeal to most sleepers, there isnt a one size fits all mattress. You can certainly find softer and firmer mattresses but if you are looking to upgrade to a memory foam mattress and are enticed by the idea of sleep tracking, this is an excellent choice.

Mattress Clarity - Joe Auer

feel of the mattress and think the technology is really awesome. My only caveat is that the sleep tracker itself changes the feel of the mattress and makes it a little bit less comfortable than it would be without the tracker. Read full review

The 11" Mars, is a well-designed blend of foam and coil layers. The Reactive Foam inside the mattress provides a bouncier surface, a quality loved by consumers not wanting to get stuck in the foamy layer. The Comfort Transition Foam with contouring features delivers best support to your body while aiding in an easy shift from the foam layer to the springy base. Regardless of sleeping posture and body weight, the Mars is a worthwhile choice for consumers preferring medium-soft feel.

The Sleeved Coils enclosed in a polyfoam act as an excellent motion-isolation tool. The coiled layer also helps dissipate heat, eventually offering you a refreshing sleep experience. The Support Foam in the mattress base provides a robust foundation for the rest of the layers. Being a high-density foam, it contributes to the enhancement of your mattress life.

  • Breathable foam layers
  • Cloud-like bounce and quick response
  • Available in various sizes (from Twin to Cal King)
  • Exceptional pressure relief
  • Suits all sleeping positions regardless of body type

The Mars is an 11 hybrid mattress, blending together the following four layers:

The top layer is Reactive Foam with 2 thickness. It is a cool and responsive surface to facilitate sleeping on the mattress rather than in the mattress. This layer has latex-like properties, offering a good bounce for pressure-relieving sleep. The quick-responding foam is a topmost priority of those changing sleeping positions often at night because of its allowance for freedom of movement.

The 2 Comfort Transition Foam is a middle layer for enabling adjustment from the foam surface above to the coiled layer below it. This is great in maintaining weight distribution and conforming support to your body.

The Sleeved Coils layer has a 4 thickness. This coiled part is surrounded by polyfoam for ample rebound and better motion isolation. The layer design allows sufficient air circulation by limiting heat retention while you are asleep.

The base of the Mars features a 3 high-density Support Foam. It provides a strong platform to the mattress layers resting above it. The base foam, being a dense and durable material, increases the mattress lifetime.
