CA 2360231
An air mattress includes a first through a fourth sheets (6, 7, 8, and 9), respectively, which are bonded together along the peripheries thereof and at a multiplicity of bonding spots, creating a triple-layer air cell structure consisting of a first, a second, and a third air cells (13, 15, and 17), respectively. A multiplicity of first bonding spots (10) bonding the first and second sheets together are spaced apart at regular intervals along longitudinal and transverse lines such that four neighboring spots occupy four corners of a tetragon. On the other hand, a multiplicity of second bonding spots (14) bonding the second and the third sheets together are arranged at positions which correspond to the centers of the tetragons. The third air cell has the same structure as the first air cell. These air cells are inflated such that the third air cell maintains high a pressure, while the first and second air cells maintain a low pressure. The low pressure air mattress may effectively prevent bedsores.
