A laminated foam mattress overlay for preventing the formation of decubitus ulcers in bedridden individuals. The mattress overlay includes an upper layer of polyurethane foam laminated to a base layer of a different polyurethane foam. The upper lay features a polyurethane foam which is of a higher density than the base layer. The upper layer also includes a higher initial softness ratio than the base layer. The base layer has higher 5, 25 and 65% indentation load deflection values (ILD) than the corresponding ILD values for the upper layer which is attributable to the firmer support provided by the foundation or base layer. The base layer is preferably thicker than the upper layer which can include a checkerboard-like upper surface. The combination of layers provides for a reduction in pressure points in the areas of greatest concern such as the hip and heel. The combination of layers work together to provide firm, comfortable support while distributing loads in the high risk areas of the body to help in avoiding the formation of ulcers.
