A method and system for wear testing a seat by simulating human seating movement are disclosed wherein load distributions and histories experienced by the seat are more accurately simulated. The system utilizes a robot and a robotic human body simulator including a pelvic girdle mounted at a distal end of an arm thereof wherein a seat back surface as well as a seat bottom surface are wear tested. The simulator includes a plurality of drives which receive drive control signals from a robot controller for moving a thoracic cage and femurs of the simulator relative to and independent of one another and the pelvic girdle to test wear characteristics of the seat bottom surface and the seat back surface of the seat under test for a plurality of cycles.
