PROBLEM TO BE SOLVED: To provide a chair allowing a user to stand up/sit down easily, capable of securing an angle to the abdomen part without causing the local pressure or slippage. SOLUTION: The seat surface of the chair consists of a flat rear half part and a front half part inclined downward in the front direction. The inclination angle of the front half part is made into an angle corresponding to that formed between the femoral region and a horizontal plane when a user sits on the chair. The user's buttocks are held by the rear half part and the femoral region is held by the front half part. COPYRIGHT: (C)2004,JPO
