A mattress comprises a support base defining an interface surface at the top thereof and a softer compressible layer overlying the interface surface. The thickness of the support base varies along a longitudinal direction such that the interface surface defines a concave laterally extending channel between first and second support surfaces for the upper and lower halves of a user's body respectively, and the compressible layer substantially follows the profile of the interface surface. The mattress is particularly useful for a pregnant woman who can comfortably lie on her back, side or front. <Figure 1> |
