An apparatus to lift persons includes: a base wheels attached to the base a vertical assembly including a fixed subassembly and a traveling subassembly a mechanism such as an actuator that powers vertical movement of the traveling subassembly a fork system attached to the traveling subassembly and comprises a pair of forks and a substantially flat seat plate that is removably attached to the fork system and includes a pair of channels along opposite sides of the seat plate. The seat plate is removed from the fork system, placed onto the floor, and is then mounted by a person. The seat plate is reattached to the fork system by inserting the forks into the channels, and the actuator is activated to lift the person from the floor. The base and fork system may be pivotally attached to the fixed subassembly and traveling subassembly, respectively, so that the apparatus is collapsible.
