Abstract: A mobility aid for use in conjunction with a toilet bowl fixture includes first and second side frames, each side frame having front and rear legs and a rail connecting upper ends of the front and rear legs, and a transverse member having first and second opposite ends. When the lower ends of the legs rest on the floor of the water closet, the transverse member is substantially horizontal and is above the upper surface of the toilet bowl. The transverse member is pivotally attached at its first end to the rear leg of the first side frame and is pivotally attached at its second end to the rear leg of the second side frame, whereby the first and second side frames are pivotable relative to the transverse member between an unfolded disposition, in which the side frames are substantially parallel to each other and substantially perpendicular to the transverse member, and a folded disposition, in which the side frames are substantially parallel to each other and to the transverse member.
