The Emma Hybrid consists of four different layers. The Airgocell® foam (4 cm) has an open-pore cell structure and enables pleasant air circulation while keeping you cool, even on warm nights. The layer of conical pocket springs (2 cm) is optimised to balance out pressure disparities. Visco-elastic memory foam (3 cm) ensures optimum pressure relief and molds to the shape of your body. The cold foam (16 cm) is the foundation and the support for the mattress.
