Abstract: A folding stool including a top having a depending peripheral skirt and support leg members operatively mounted on the underside of the top, and inward of the peripheral skirt. Leg members are mounted at opposite ends of the stool. Each leg member includes two legs interconnected as a pair. The leg members are pivotally moveable to an extended stool support position, and to a retracted folded position within the confines of the skirt. Selectively engageable double leg locking means are provided, with portions thereof being on the stool top and portions thereof being on the legs of the leg members. The locking means are functionally operable for locking the leg members in the extended stool support position. Engagement and disengagement of the double locking means is manually effected by rectilinear movement of the leg members, toward the stool top when in the extended stool support position. Pivotal movement of the leg members is prevented with the locking means operatively engaged.
