ABSTRACT:
A laminated mattress construction having outer layers of relatively soft, virgin foam material and an inner layer or core made of firmer reground, bonded foam. The thickness and firmness of the core are varied in relation to that of the outer layers to achieve a mattress having an overall compression modulus of at least 3. Individually the outer layers are so constructed as to exhibit a 25% ILD range of 10-45 lbs. and the core is so constructed as to exhibit a 25% ILD range of 20-80 lbs. The mattress is further constructed in horizontally juxtaposed sections with one section having firmness characteristics which differ from another section. Finally a removable mattress covering is provided which permits removal of the foam core and separate cleaning or replacement thereof.
