A lightweight, two piece wheelchair wherein both pieces are separable and optionally foldable. The wheelchair is driven manually by rotating a pair of opposed handwheels, one of which is contacted by each of the occupant\s hands. When a seat positioning crank is rotated by the wheelchair occupant, a seat raising mechanism is activated which moves the seat from a horizontal sitting position to an inclined but substantially vertical position toward the front of the wheelchair. As the seat is raised, the contour of the seat is altered to provide added comfort for the occupant in the standing position.
