Abstract: A sunshade apparatus for shading a chair has a pair of vertical support legs, a pair of attachment elements, a pair of horizontally extending arms, and a flexible canopy element for shading the chair. Each of the attachment elements is attached to a bottom end of one of the support legs and is adapted for mounting the sunshade apparatus on the chair. Each of the pair of horizontally extending arms is attached to one of the support legs with a hinge. A locking element functions to lock the pair of horizontally extending arms in the extended configuration with respect to the pair of vertical support legs. A folding element joins the horizontally extending arms and folds between a collapsed configuration wherein the arms are adjacent, and a spread configuration wherein the arms are laterally spaced.
