The aim of this study is to meet safety requirements while increasing the comfort of drivers and passengers. This paper analyzes the comfort of seat headrest from three perspectives, these three influencing factors are head restraint modeling, foam performance and skin buoyancy. By improving the thickness of the foam and optimizing the shape structure, the head comfort of the drivers and passengers is improved, and the driving experience is improved.
