A reversible contoured body support mattress is formed of a foam block having a first major surface which is convoluted to form a regular pattern of hills and valleys. The opposite major surface is contoured in mutually perpendicular directions to provide a configuration which substantially conforms to the body shape in both the longitudinal and latitudinal directions, yielding a structure having therapeutic values for users, with or without spinal problems. As an alternative, the mattress may be formed of a first convoluted layer affixed to a second contoured layer wherein the contoured surface may be either affixed to or remote from the flat surface of the convoluted layer.
