A wheelchair cushion having a solid gel patient interface, a matrix or honeycomb panel and a foam base. The gel layer is mold around and over the honeycomb panel to produce a composite panel with patient interface characteristics of a gel layer, but with reduced weight. The matrix panel cells are open on the lower ends which are bonded to a soft foam base. The matrix panel interacts with the foam base to spread forces and provide pressure reduction and positioning better than solid gel, but with less weight. The foam base may include several layers of differing density and contouring elements. The composite panel conforms to the base contours to provide a contoured patient interface.
