ABSTRACT:
An anatomical mattress comprises at least two layers of elastic material each having a main surface. The elastic layers are joined along the main surfaces thereof to define a generally parallelepiped-shaped body. The body has a peripheral frame and two opposite surfaces. At least a portion of one of the opposite surfaces of the body has semispherical-shaped elements extending outwardly therefrom and defining a lying plane of the mattress. At least two transverse reinforcing and stiffening bands are disposed in the body at positions corresponding generally with the shoulders and feet, respectively, of a user.
