ABSTRACT:
Custom-profiled seating for a wheel chair or other body support seating systems includes seat and backrest members having outer covers in which a liner bag is removably accommodated and into which expandable, curable foam-in-place material is introduced to conform to that portion of a person's body which is to engage seat or backrest to attain a custom fit. The seat and backrest members are provided with access openings sufficiently large to enable the liner and resultant foam cushion member within the liner to be removed from the cavity for reshaping or replacement.
