Abstract: A locking device for a foldable collapsible seat is provided. The collapsible seat includes a plurality of legs. A pivoting mechanism pivotally connects together the plurality of legs. A limiter device extends between the plurality of legs for preventing the plurality of legs from spreading beyond a predetermined supporting position. A seat portion is mounted to an upper end of the plurality of legs. A locking device is removably positioned above the pivoting mechanism for wedging apart the plurality of legs and increasing a rigidity of the collapsible seat in an expanded, setup position.
