ABSTRACT:
A lumbar support cushion consists of a seat portion and a back portion, foldably joined along a crease positioned therebetween. An opening extends in a continuous manner upward into the back portion, and downward into the seat portion. The opening may have an oval shape. In one embodiment, a support member is provided, and is positioned across the front of the back portion. The position of the support member along the back portion may be made adjustable, for example by the use of mating hook and loop material on the support member and a rear portion of the back portion.
