Abstract

A mattress pad (1) is multi-layered and includes a cover or casing (5, 7) containing interior strata of a plastic film (17) layer atop a fluid bladder layer (19) supported on an underlying layer of foam (21). The reduction of the lateral shearing forces on a user of the pad is accomplished by oversizing the plastic film layer (17) and fluid bladder layer (19) on the underlying layer of foam (21) and by positioning microbeads between the plastic film layer (17) and fluid bladder (19) layer to dramatically reduce the friction drag or lateral shearing forces between the layers. Normal pressures and forces are reduced by oversizing, modifying the configuration, filling, and size of the discrete fluid pouches (41, 41', 41") of the fluid bladder layer (19), and varying the spring characteristics of the support columns (49) in the underlying foam layer (19) by hollowing them out to different degrees (53, 53'), adjusting their spacing, selectively tying adjacent columns (49) together.
