The nature of the invention enables the same tennis backboard to be used in any of the three standard backboard positions; vertical, sloped, or curved. Furthermore, the design allows for the angle of slope, and the curvature of the board, to be made at the location where the board is mounted. The material used is a paper/resin composite product that is durable, dense, flexible, and not affected by adverse weather conditions. The invention incorporates flex technology allowing the board to flex upon impact from a tennis ball. The same framework can be used to mount the backboard to an existing chain-link fence, concrete wall, brick wall, stud wall, portable platform, or other sturdy structure.
