A lift wheelchair having a slide assembly seat support mechanism is disclosed. An extension element or cylinder is used to force a seat-supporting slide assembly upwardly and outward from the wheelchair frame. Stabilizing means are employed to accommodate the shifting center of gravity of the wheelchair-occupant system, and arms on the seat may be pivoted to create a transfer-assisting bed-board or slide. One or more lift arms may be used to transfer the force from the extension element to the slide assembly and to provide load bearing support and seat stabilization for the wheelchair assembly.
