The purpose of this study is analyzing commercial office chair that equipped with synchronized tilt mechanism which is characterized by the seat tilt synchronously with the backrest. The kinematic analysis of human-chair system during tilt was performed using dynamic simulation software. Five commercial office chair was selected and link system of tilt mechanism was modeled. Tilting angle of seat and backrest was calculated and the trace of eye, shoulder, hip and knee were analyzed by performing tilting simulation of human-chair system. There are various tilting characteristics among commercial office chairs and it affect on the human tilt motion. Human motion and comfort is priority requirements when designing office chair. And the tilt mechanism can be designed to support the aimed human motion.
