Abstract
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° 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.

Total Claims: 15
Claim 1
Independent Claim
164 words
A mattress, comprising: a body portion having a generally planar top surface; a head portion longitudinally spaced from said body portion, said head portion being longitudinally bifurcated to provide relatively movable, upper and lower sections; and hinge means pivotally coupling said upper section to said body portion along a hinge axis substantially coplanar with said top surface; said upper section including a lower surface having a shoulder extending therefrom, said shoulder being adjacent an end of said upper section remote from said hinge means; said upper section being rotatable through approximately 180° about said hinge axis from a first position overlying said lower section to a second position overlying said body portion top surface; said upper section having a planar upper surface coplanar with said top surface of said body portion in said first position, and tapering in thickness away from said hinge means to expose a surface of said upper section in said second position extending downwardly and away from said hinge means.
Claim 2
Dependent Claim
