Sitting posture is common in daily life and approximate 75% of laborers usually work in sitting postures. Inappropriate sitting conditions for a long time could cause serious musculoskeletal disorders like lordosis, back pains. For this reason, studies on biomechanical and/or ergonomic features of human body are necessary for an optimal design process of chair system like chair, sofa, wheelchair, etc. In this Study, biomechanical tests to measure body pressure on seating area and muscle activities of human upper body by EMG sensors were performed to review optimal design parameters necessary for chair system development suitable for users.
