ABSTRACT:
A rollator with a tubular frame assembly includes a pair of U-shaped side frames connected by a front brace. Each side frame has a cross bar that extends between front legs and back legs of the frame. The side frames are pivotably attached to the front brace so that the side frames can fold inwardly. The rollator has a molded rigid seat that is mounted on pivot brackets to allow it to pivot upwardly out of the way of the user. The pivot brackets have an offset axis of rotation so that the seat is arranged in a curved area of the front brace when pivoted upwardly.
