Abstract: There is disclosed a folding bed or diaper changing platform for an infant which has a pair of cross frame members pivotally interconnected to move between folded and unfolded positions. Each cross member and distally supports a longitudinal foot that extends to the corresponding, opposite frame member. The foot members are obtained at 45 degrees to the legs of the frame members, thereby forming a horizontal foot for enhanced stability of the furniture in its open or unfolded configuration and for assuming a spread stance in the folded position which, again, provides a stable configuration. The upper ends of the cross members distally support longitudinal upper rail members which, preferably, have a coextensive lip that is also oriented at 45 degrees to the plane of the longitudinal upper rail members. The conextensive lip members fixedly support snap receptacles for snap fasteners whereby a canopy can be removably attached to the furniture in its unfolded position.

Abstract: A rigid carrying case (20) having a handle and a hinge in the center, is combined with a removable flat top (22) that is attached when opened forming a portable table. Legs (52) are stored within housings (32) located inside of the case (20) and are released by depressing an actuator (64) protruding outside of the case perimeter. The legs (52) cross each other thereby holding them rigidly in place with assistance of a non-slipping resilient bumper (60) on the end of each leg. The housing (32) is attached inside the case (20) with a housing cap (36) on one end and restraining means on the other consisting of a locknut (44), spacer (46), locknut with a lip (48), and an "O" ring (50). A second embodiment adds a separable leg extension (80), and a third embodiment adds length to the legs (52) utilizing a second telescoping leg (82).
