Ventillated mattress with semi-spherical projections

An anatomical mattress comprising:

• at least two layers each having a main surface, the two layers being connected along the main surfaces thereof to define a generally parallelepiped-shaped body, the body having a peripheral frame and two opposite surfaces, at least a portion of one of the opposite surfaces having a plurality of generally semi-spherical-shaped elements defining a lying plane of the mattress;
• at least three transverse reinforcing and stiffening bands disposed in the body, a first one of the transverse reinforcing and stiffening bands being disposed substantially in correspondence with the shoulders of a user when the user lies on the mattress, a second one of the transverse reinforcing and stiffening bands being disposed substantially in correspondence with the buttocks of the user, and a third one of the transverse reinforcing and stiffening bands being disposed substantially in correspondence with the feet of the user;
• and a plurality of ventilation holes disposed in the semi-spherical-shaped elements, in the peripheral frame, and in the first, second and third transverse reinforcing and stiffening bands, the ventilation holes extending generally perpendicular to the lying plane of the mattress.

An anatomical mattress comprising:

• at least two layers of elastic material each having a main surface, the two layers of elastic material being connected along the main surfaces thereof to define a body having a peripheral frame and first and second opposite surfaces, at least a portion of the first surface of the body having a plurality of semispherical-shaped elements extending outwardly therefrom to define a first lying plane of the mattress;
• and a plurality of reinforcing members disposed in the body along the first lying plane of the mattress at positions corresponding generally to the shoulder, buttocks and feet of a user when the user lies on the mattress.
