ABSTRACT:
A mattress comprises a body portion and a head portion longitudinally spaced from the body portion. The head portion is longitudinally bifurcated to provide relatively movable, upper and lower sections. The upper section is hingedly coupled to the body portion along a hinge axis substantially coplanar with the planar top surface of the body portion. The upper portion can be rotated through an angle of approximately 180.degree. about the hinge axis from a first portion overlying the lower section to a second position overlying the body portion top surface. Additionally, the upper section may be located in any desired angle between the first and second positions. In this manner, the mattress has a wide variety of functions.
