A chair structure includes a main body and a cushion. When the cushion is disposed on the cushion frame of the main body, the cushion is forwardly inclined to naturally enable the pelvis of the user to incline in the same manner and enable the lumbar vertebra to naturally curve, so that the ischium of the user's hips would sustain most upper body weight of the user instead of the pelvis. Also, it reduces the pressure between the thigh of the user and the front edge of the chair, so the user can sit on the chair for a longer period of time while the spine can naturally maintain an S shape to reduce physical/physiological uncomfortableness caused by improper sitting manner. |
