The invention mainly relates to the field of pressure testing, and provides a dummy for testing the pressure comfort of an office chair. The head, the chest, the back, the left upper arm, the right upper arm, the left front arm, the right front arm, the left hand, the right hand, the buttocks, the left thigh, the right thigh, the left shank, the right shank, the left foot and the right foot are designed according to the human body size of the 50th percentage Chinese adult male, and the mass and centroid positions of all body sections are configured according to standard adult human body inertia parameters. Meanwhile, 22 pressure sensors are mounted on the sides, in contact with the office chair seat surface, of the buttocks, the left thigh and the right thigh; the pressure sensor is used for collecting pressure signals of the contact side of a dummy and an office chair seat. The comfort of the office chair is analyzed according to the pressure signal, the structure is designed according to Chinese standard human body data, and the pressure distribution condition of a real person sitting on the seat surface of the chair can be accurately simulated, so that the pressure comfort of the office chair is accurately evaluated, a large number of real persons are replaced for testing, and the testing time and labor cost are saved.
