Abstract
A portable lumbar support cushion system providing support to the lower thoracic and lumbar spine, without exerting direct pressure on the same, as well as, providing a pressure release for the sacrum and coccyx. This is accomplished by a first and second cutout in the seat cushion and back cushion, respectively, and a vertically adjustable, interchangeable support of variable thickness that mounts on the rear of the back cushion. The support is mounted in a position that is between a chair back and the back cushion, where it exerts pressure on the back cushion that causes the back cushion to form a curved shape around the support. As such, the back cushion presents a corresponding curved shaped bulge that supports the spine curvature of the seated occupant along the sides of the back cushion flanking the second cutout along an area that overlays the lower thoracic and lumbar spine.
