1. An air mattress, comprising:
a plurality of air cell groups including a plurality of air cells and lined up with respect to a lengthwise direction of the air mattress so as to support at least a shoulder area, a back area, a buttock area, a thigh area, and a knee area of a person lying on said air mattress; an air supply/release pump; an air tube connecting said air cells and said air supply/release pump in one or a plurality of independent first systems for each of certain air cell groups out of said air cell groups and one or a plurality of independent second systems for each of specific air cells out of a remainder of certain air cell groups out of the plurality of air cell groups; and a controller for controlling air supply/release by the air supply/release pump to said first systems and second systems, wherein each of the air cell groups corresponding to said back area, buttock area, and thigh area includes a lower section of air cells and an upper section of air cells, wherein the lower section air cells are connected to said first system via said air tube, and wherein each of the air cells in each of the air cell groups corresponding to said shoulder area, knee area, as well as the upper section of the back area, buttock area, and thigh area, are connected to one system out of the plurality of said second systems via said air tube. |
