A foldable wheelchair includes a frame having a seat bottom and a seat back movable relative to the seat bottom, wherein the seat back can be moved between a folded position such that the seat back extends generally parallel to a plane defined by the seat bottom and one or more unfolded positions to provide back support to a user. The foldable wheelchair can have a leg support movable relative to the seat bottom and can be moved between an unfolded position to support a user's legs and a folded position such that the leg support extends generally parallel to said plane defined by the seat bottom. In the folded position, the seat back, seat bottom and leg support define generally parallel planes.
