ABSTRACT:
A body supporting device comprises a first plastic section having oppositely disposed inner and outer surfaces. The outer surface is disposed above the inner surface and permanently defines a plurality of closely spaced regions of like size and contour which are interconnected by channels disposed below the regions. The inner surface of the first section permanently defines a like plurality of deep recesses. Each deep recess constitutes the inside of a corresponding region. The deep recesses are interconnected by shallow recesses. Each shallow recess constitutes the inside of a corresponding channel. The device further comprises a second plastic section sealed to the inner surface of the first section in a manner at which the deep and shallow recesses communicate with each other. A flexible hollow tube is diposed about the periphery of the sections and is secured thereto. The tube interior is connected via openings in the tube to the shallow recesses. The tube and sections are sealed to each other to prevent air and water leakage between the interior of the tube and sections and the outside thereof.
