    Abstract: A stand-assist chair has a base, front and back wheels on the base normally supporting it rollably on a floor, a seat having a front edge and a back edge, a back extending upward from the back edge of the seat, and a pair of lever systems engaged between the seat and the base operable to displace the seat between a normal sitting position with the seat front edge somewhat above the seat rear edge and a stand-assist position with the seat rear edge somewhat above the seat front edge and the entire seat elevated above the level it occupies relative to the base in the normal sitting position. A drive motor is engaged with the lever system for displacing the seat between its positions. A pair of respective feet are movable on the base between a retracted position above a plane defined by lowermost surfaces of the wheels and an extended position projecting downward past the plane and lifting at least one of the wheels off the floor.
