Abstract: An adjustable matrix wheelchair seat can be mounted on a pair of rods such as are provided on the seat rails of a typical wheelchair or on any pair of rods adapted to be rigidly fixed to and aligned in a longitudinal direction relative to the frame of the wheelchair. A lateral array of spaced apart substantially inelastic straps is extended between and engaged on the rods. A longitudinal array of spaced apart substantially inelastic straps is engaged on the forwardmost and rearwardmost straps of the lateral array. The longitudinal array traverses the lateral array to define a horizontal matrix of ventilating interstices. The length of any or all of the straps of the lateral and horizontal arrays is independently adjustable to permit alteration of the pressure pattern imposed on the arrays by the patient occupying the seat.

Abstract: A cover for a wheelchair seat is made from a cloth having a first ply of wicking material for drawing moisture that contacts the first ply away from an occupant of the wheelchair and a second ply of absorbent material for drawing moisture out of the first ply and dispersing the drawn moisture in the second ply. The first and second plies are permanently secured in laminar relationship to each other, preferably by a hem along their perimeter. The cloth is detachably mounted on the wheelchair seat, preferably either by an elastic band positioned within the hem, the band having a length in its unstretched state which is less than the length of the hem, or by a plurality of hook-and-loop fasteners fixed in spaced apart relationship to the cloth and extending outwardly from the hem to a plurality of mating hook-and-loop fasteners fixed to the cloth proximate the hem. The elastic band mount is specially preferred for use with removable wheelchair seat cushions.
