Nuvanna’s mattress consists of a three-layer foam system. The top Ascension Layer uses highly adaptive foam to cradle the entire body; the Equilibrium Layer is built for motion absorption, contouring to sleep movements for continuous support; and the Foundation Layer provides progressive support for the entire system and prevents sinking, according to the company. The foams are certified by the CertiPUR-US program and encased in a mattress cover made of Tencel fabric.
