Abstract
A walker device for assisting an individual with mobility which is temporarily convertible to a wheeled transportation chair, includes a frame structure having two front legs and two rear legs, each of the legs having a leg extension adjustably attached thereto and supported on a rotatable wheel. A seat is attached to the frame structure. A backrest is selectively disposed in a front position for a rearward seating condition or in a rear position for a forward seating condition. A footrest assembly is optionally attached to the frame structure and is adapted to pivot about first and second pivoting axes parallel to each other, between a folded position and an unfolded position optionally with different height levels.
