The present invention provides a standing mobility and/or transfer device for handicapped users including an articulating foot platform system effective to move a foot platform between a rearwardly tilted user-receiving condition located close to the floor and an elevated, forwardly tilted condition for user transport at a standing-prone angle. Bilateral lift arms move in concert with the raising and lowering function of the foot platform to elevate the person to a standing-prone position from a seated position. In a raised position, the lift arms are located alongside a user to provide additional posture control. Optional motors associated with one or more wheels of the device may be controlled by the user with a joystick for self-propelled standing mobility.
