We created the Emma mattress with you (and your needs) in mind. The recipe for a good night's sleep is simple: Using only the finest British memory foams and the latest technologies we developed an extremely comfortable mattress that also offers support and pressure-relief in the areas you need the most. The open-pored, three-layered memory foam structure also allows for great air circulation. 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.
