24 project upwardly from the flexible lower panel 22 in a spaced relationship relative to one another a flexible upper panel 26 extends between the flexible lateral panels 24 of an individual one of the separate chambers 20 to define an interior compartment 28 within an individual one of the chambers a viscous gel 30 is positioned within the interior compartment 28 to support the flexible upper panel 26 relative to the flexible lower panel 22 and to the flexible pad means 12 to which the lower panel is attached by this structure each of the separate chambers 20 operates to support an individual portion of a human body relative to the flexible means 12 and the mattress 14 when the device 10 is positioned relative to a bed 16 as shown in fig1 it is important to note that the interior compartments 28 of each of the separate chambers 20 are precluded from fluid communication with the interior compartments of adjacent chambers 20 such isolation of the viscous gel 30 within each of the interior compartments 28 of the separate chambers 20 precludes a pressure induced biasing of the viscous gel 30 into outer portions of the individual support means 18 thus each of the separate chambers 20 operates independently relative to adjacent separate chambers to support an individual portion of a human body as best illustrated in fig4 and.
