The cushion is economical in its construction, simple to operate, and it requires little or no maintenance. Moreover, it is easy to store. It is self-contained and readily portable.
The cushion, in the embodiment to be described, is constructed of a fabric casing filled, for example, with polyurethane foam, a soft wire grid, or other appropriate resilient material.
The cushion is provided with a seat section and a back section hinged to one another. An inflatable bladder is mounted in the back section to be positioned adjacent to the lower lumbar region of the back of the user.
A hand-operated pump is provided for inflating the bladder to a size tailored to the individual using the cushion. The pump is preferably equipped with a quick release pushbutton for fast deflation of the bladder.
The cushion may be reversible. One side of the cushion may be covered with simulated sheepskin, if so desired.
