Abstract
A collapsible mobility device is comprised of a base with a vertical support and a seat, all supported on wheels. The base is capable of being folded in upon itself. The vertical support is capable of being extended and retracted. The seat can be pivoted in an upward position. The wheels can be locked in various positions so that the device is capable of serving as a stool, a swivel chair, a wheelchair, a luggage rack, a walker and a wheeled cane. Ultimately the entire device can be collapsed to a size such that it can be stored in an overhead bin or under the seat of a commercial aircraft or other common carrier.
