ABSTRACT:
A back rest cushion, useable with automobile seats and chairs, has a centralized vertical channel for non-contactingly receiving a user's spine. Resilient step tapered members extend upwardly to provide firm support at the upper buttocks and in the lumbar region while conforming to normal curvature of the backbone. The back of the cushion is semi-rigid and curved about a vertical axis to encourage lateral support for the rib cage while the channel precludes lateral pressure upon the spine.
