Abstract
A seat back or seat bottom cushion incorporates one or more inflatable/deflatable air chamber bladders. The cushions are integrally formed with the bladders by suspending the bladders in a clam shell type mold and then injecting chemicals in the mold to form a urethane foam or the like. The cushion resulting from the molds may include the outer upholstery covering as part of the molded assembly. Each bladder molded into the cushion has a port that permits passage of air into or out of the bladder.
