Each supporting part is respectively provided with an air feed and discharge part for feeding or discharging air. Air is filled through the air feed and discharge part. In this way, the shape of each chamber is turning from a flat state to a state inflating along the thickness direction. Thus the buttocks and the thighs of a sitter can be supported. The air cushion is characterized in that each supporting part respectively comprises a first chamber equipped on the front side, a second chamber configured in a way to be side by side with the first chamber and located more adjacent to the other supporting part than the first chamber does; and a third chamber equipped on the rear side, communicated with the first chamber and the second chamber and having a larger size than those of the first chamber and the second chamber. The right side supporting part is not communicated with the left side supporting part. The air cushion in the invention can correct the lateral inclination of a human body. |
