Abstract

A seat cushion for a chair having a contoured, padded base with an inflatable air cell pad positioned securely within the base and encased within a cover. The air cell pad is optimally located in the base so as to be positioned under the user's buttocks, particularly under the areas of high-pressure areas on the buttocks of a normally positioned user. The inflatable air cell pad is operatively connected to a pump device positioned on the chair for access by a seated user of the chair. The user can sit on the cushion and inflate or deflate the air cell pad for optimal support and comfort. In one aspect of the invention the pump comprises a bulb and valve combination.
