An indoor recreational system adapted for use with a door frame is disclosed. The indoor recreational system is provided in component parts and is foldable to reduce storage space when the system is not in use. The recreational system comprises two foldable upright members having a groove on one side adapted to be received about the inwardly facing rib of the door frame and two longitudinal members having slots at each end to be received about the frame rib to prevent lateral movement and a shoulder on each end of longitudinal member to engage and prevent inwardly movement of the upright members. A number of interchangeable recreational devices can be used with the indoor recreational system including a swing seat, an exercise bar, a slide, two exercise rings or a child's safety seat. A method of installation of the indoor recreational system is disclosed to achieve the greatest installed height for the upper longitudinal member.
