ABSTRACT:
The sectional non-slip mattress includes a support frame defining a plurality of compartments and at least one cushion having a plurality of ball bearings received within a cushion housing. Each compartment receives a corresponding ball bearing, thus preventing horizontal movement of the cushion with respect to the support frame. The ball bearings form a first material layer and a second material layer is formed from a set of elastic beads, each having a volume smaller than a volume of each of the ball bearings. A third material layer is formed from a plurality of gel-filled capsules and the three material layers are all housed within a fabric cushion housing, which is permeable to air. An additional air supply may be provided for driving pre-cooled or pre-heated air through the cushion.
