Overview of Benefits

The Eight Sleep has a wide range of satisfied customers across multiple countries. The brand believes this as a result of incorporating user reviews before designing any new product.

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.

Technology Details

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.
