摘要：
A folding backrest has a rigid rectangular frame supporting a resilient fabric planar panel stretched thereon. A wedge shaped support structure folds flat against the fabric for storage and transport and unfolds to support the frame tilted up on the sand with either end of the frame against the sand to provide selectable high or low inclination angle on the supporting sand. The panel fabric may extend beyond the frame ends to provide a covering on the sand for sitting thereon.
