The Memory King mattress gives you 200mm of quality foam to slumber on comfortably. Made up of 125 mm of reflex foam topped with 75mm of Visco elastic memory foam, it is tour passport to the land of sleep. It is covered in a superior, ‘stress free’ stretch fabric that enhances the action of the memory foam. In addition, this is micro-quilted, with a thick layer of polyester that allows your mattress to breath and keeps you comfortable all night.
