The thickness of this comfort layers means it offers moderate yet consistent body conforming which can alleviate pain and tension.
It also aids back alignment especially for side sleepers.
The mattress is aerated and with the patented temperature regulated cooling AirGel, airflow is increased throughout the mattress, moving heat away from the body.

Bamboo-Infused PolyFoam Layer
The transitional layer is made up of 2” of bamboo-infused eco polyfoam.
This layer offers dynamic pressure relief giving additional support and firmness, a smart material which cradles your unique curves, offering close body conforming.
It works well between the comfort layer above and the support layer below.

HD Polyfoam Base Layer
This foundation layer is constructed using 5” of supportive high-density polyurethane foam.
It is robust and firm giving the mattress a stable and sturdy feel while evenly distributing and supporting your weight throughout the mattress.
