Computer design and fabrication of custom-contoured seating.

This article describes the development of a computer-controlled system for measuring anatomical contours and forces at the interface with seat surfaces. The system was designed to eliminate the cause of pressure sores, which are a major problem for wheelchair-bound individuals. A parallel and compatible system also has been developed for the rapid, precise, and cost-effective fabrication of custom-contoured seat cushions and other body supports from a range of open- and closed-cell foam materials.
