A foot support for a bed rests on the upper surface of the mattress and includes an upwardly inclined foot plate. Lateral motion and twisting of the foot support with respect to the mattress are prevented by downwardly depending fences that lie adjacent the sides of the mattress. In a preferred embodiment, the foot support consists entirely of flat stock which results in a unitary structure that is easy to clean and that nests so that a number of the foot supports can be stacked for storage in a relatively small space.
