Abstract: A plate-like support member of rectangular configuration has a surface, a first pair of parallel edges and a second pair of parallel edges perpendicular to and shorter than the first pair of edges bounding the surface. A mounting device is swivelly affixed to the support member at an upper of the first pair of edges and swivelly affixed to the headboard of a bed for adjustably selectively positioning the support member relative to the headboard. A ledge extends from the surface of the support member along a lower of the first pair of edges and has a first ledge surface parallel to and spaced from the surface of the support member and a second ledge surface perpendicular to the surface of the support member and extending from the surface to the first ledge surface for supporting a book resting on the support member in open position.
