Abstract
A cushion having a sitting surface is provided that includes a three dimensional system of rigid plastic levers used in combination with a foam cushioning material. Weight applied to the cushion is borne by the plastic levers. When sat on, the cushion conforms to the user's body and automatically shapes itself to uniformly distribute support pressure within each of four seat quadrants. As the body shifts in position, the cushion automatically reconfigures itself to maintain substantially uniform pressure distributions. Construction details and a method for low cost manufacture are presented.
