ABSTRACT OF THE DISCLOSURE A hollow, air filled body support cushion such as a seat cushion or mattress is formed from typically three interfitting matrices each comprising a set of hollow cells formed from natural or synthetic rubber or rubber- like plastic. The cells of each matrix are spaced apart to accommodate between them cells of each of the other matrices to define a body support surface made up of the tops of all of the cells. Each matrix has separate fluid ducts between its cells. Each matrix has separate fluid ducts between its cells. A fluid pressurizing and control means such as air pumps is used to inflate and deflate the matrices in sequence to shift body support from one set of cells to another for promoting blood circulation and enhancing comfort.
