Abstract
A seat is attached to the top of a vertically disposed trunnion member mounted for rotation about a vertical axis relative to a vertically disposed tubular intermediate member. The trunnion member and intermediate member are vertically adjustable together relative to a vertically disposed tubular base member. All three members are secured together into an assembly by a plurality of securing elements. The seat and trunnion member cannot be removed from the assembly without removing or disengaging a securing element. None of the detachably engaged securing elements are accessible. The only accessible securing element cannot be removed from a securing disposition without destruction thereof. This provides an effective mechanical and psychological deterrent against theft of the seat.
