ABSTRACT:
A wheelchair that is light in weight and collapsible has drive wheels that are readily removed to reduce its weight and enable a handicapped person or other user to fold it up while the user is in a sitting position. The user may readily change it from a conventional wheelchair to an invalid's caster chair and back. The wheelchair has a fabric seat, seat back, and leg support to reduce its weight, make it inexpensive to manufacture, and make it easy to collapse, and it has no arms to make it easier for a handicapped person to get into and out of the wheelchair.
