The Emma mattress adapts perfectly to anyone of any sleeping style (side, belly, and back sleepers) and regardless of body weight. The materials used in the mattress offer the necessary support as well as pressure relief for your best night’s sleep. The Airgocell foam (1.5 in) has an open-pore cell structure and enables pleasant air circulation while keeping you cool, even on warm nights. Visco-elastic memory foam (2 in) ensures optimum pressure relief and molds to the shape of your body. The cold foam (8 in) is the foundation and the support for the mattress.
