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.
