For the wheelchair users, pressure distribution cushion is essential to prevent pressure ulcer. On the other hand, cushion needs to have the function of keeping sitting posture, especially for spinal cord injury, cervical cord injury or elderly persons. For this issue, we propose the cushion with a layered structure of the silicon rubber block cube. This contrivance provides both of the scattering pressure and maintaining sitting posture. The block cubes are constructed by wrapping soft silicone rubber up in the hard silicone rubber. And because of the layered structure, the cushion can be custom-made to fit the shape of the individual users' hip. In this paper, we have tried to develop custom-made silicone rubber cushion and we compared the pressure distributions when users use the silicon rubber cushion and same shape urethane cushion. Both of silicon rubber and urethane cushion have excellent enough performances of the pressure prevention. The pressure distributions by using the silicone rubber cushion haven't showed big difference according to the wheelchair tilting. These results suggest that the silicone rubber cushion has the good performance of keeping users' body posture on their wheelchair.
