A person load and unload transfer device including an adjustable wheeled base frame a support structure mounted on the base frame a person load and unload assembly mounted to the support structure and includes a person receiving portion adapted to change configuration between a load and unload operating condition an actuator mechanism to selectively control the assembly wherein in a load operating condition the assembly urges the person receiving portion to adopt an angled position relative to the wheeled base to stably receive a person and in an unloading operating condition the assembly alters the angle of the person receiving portion to allow transfer of the person from the transfer device. The geometry of the person support assembly is such that it helps to keep the person in the upright position as it moves from the load or unload position to its position in the center of the person transfer device.
