An apparatus for assisting people with walking wherein those apparatus are reconfigurable to provide seating in either the forward-facing, or the rear-facing direction, includes a foldable, wheeled frame assembly, a seat mounted to the frame, and a reversible cross-arm, or backrest, for reconfiguring the apparatus from a rear-facing seating arrangement to a forward-facing seating arrangement. In a further aspect, hinged arms, one on each side of the frame assembly, are operable to at least partially rotate in a plane adjacent to the plane of the frame to which it is attached, thereby offering alternative positions of the arms that are convenient to the forward-facing seating position and the rear-facing seating position.
