A frame system that is adjustable in size and shape is provided with components that move in relation to each other. The frame system uses support rails, side rails, and a center rail to configure the different components to a desired shape and size. Each support rail includes a middle support piece and a pair of adjustable support pieces that move within the middle support piece. Each side rail includes a middle side piece and a pair of adjustable side pieces that move within the middle side piece. The center rail includes a middle center piece and connecting pieces that connect to a slot within each middle support piece. Legs mount the support rails and side rails while the center rail uses a leg piece.
