<p>This invention relates to a bed mat. A mat main body comprises a core material (3) made of a rigid foamed material having a sufficient thickness, protective sheet members (4), (5) placed on the front and reverse surfaces of the core material while sandwiching the core material (3) between them and surface layer materials (6), (7) made of a cushion material and put on the protective sheet material (4), (5). At least one of the surface layer materials (6), (7) is formed by superposing a second cushion layer (11) made of a semi-rigid cushion material having a corrugated surface (13) on its surface on a first cushion layer (10) made of a soft cushion material. A conventional bed mat has a structure incorporating a plurality of coil springs fixed to a metal frame, and is not free from problems that the total weight is heavy and the mat is difficult to handle. In accordance with the present invention, the rigid foamed material is used as the core material (3) without using the metal member. Therefore, the mat of the present invention is light in weight and is free from problems such as rust and breakage. Moreover, since the corrugated surface (13) of the second cushion layer (11) in the surface layer material supports the body in a point contact state, air permeability is high and finger-pressure action is provided to promote health.</p> |
