Abstract: A sunshade assembly removably mounts to outdoor furniture, such as a lounge chair, and includes a canopy structure having first and second pivotally movable frame members, and a foldable material canopy fitted to and extending between the frame members. A tensioning bar removably secures to the respective frame members at opposite ends to maintain the frame members separated so that the canopy is pulled taut, thereby blocking the sun's rays and creating an area of shade. A telescoping support arm attaches to the furniture at one end and to the first frame member at an opposite end and is adjustable in length to selectively position and maintain the expanded canopy throughout a range of adjusted positions relative to the furniture, thereby controlling the location of the created area of shade. The canopy structure collapses behind the furniture upon removing the tensioning bar and releasing the lower end of the support arm from attachment with the furniture.
