ABSTRACT:
A plurality of flexible tubes is disposed in a rectangular, elongated mattress body made of a foam such as urethane, rubber or the like and having top and bottom panels as well as side and end panels. A first set of tubes lies within the body in a plane parallel to the top panel and the first tubes extend in the longitudinal direction of the mattress body. Second and third sets of tubes are disposed in second and third planes parallel to the top panel, are on opposite sides of the first plane and extend in the transverse direction of the body. All the tubes merge with the side or end panels. The tubes are plugged to enclose air, each tube being provided with a valve for filling or releasing air to establish a desired pressure. If desired, the tubes in each set or all tubes can be interconnected by a manifold arrangement to facilitate air filling and releasing.
