The invention relates to an office chair and discloses a chair capable of intelligently adjusting the sitting posture. The chair comprises a chair plate, chair legs, handrails and a backrest, whereina plurality of elastic fluid bags are respectively arranged on the backrest, the chair plate and the handrails; pressure sensors are connected between the fluid bags and the chairs in a pressurizationmanner, the fluid bags are communicated through one-way pumps, and the pressure sensors and the one-way pumps are connected with a controller through signals; the controller is used for receiving pressure signals of the pressure sensors and sending the control signals to the one-way pumps; the parts, far from the chair legs, of the fluid bags are thick wall parts, and the parts, close to the chair legs, of the fluid bags are thin wall parts; and after the pressures of the adjacent fluid bags are balanced in real time by the controller, the pressures of the fluid bags gradually decrease alongthe direction far from the chair legs. When a user reclines on the chair, the pressures of the fluid bags under thighs are higher than the pressures of the fluid bags under legs, and the pressures inthe adjacent fluid bags are regulated to be decreased along the direction far from the chair legs by virtue of the controller, so that the sitting posture of the user is corrected, and the user can relatively comfortably sit.

Problems solved by technology

[0004] However, when the user sits on the chair for office work, under the action of the gravity of the upper body, the body will tilt downward along the surface of the backrest in the vertical direction, the curvature of the lumbar spine will become larger, and the body will be in a reclining posture. After maintaining the reclining position, the degree of physical fatigue and damage will increase significantly
