Abstract: A device includes a main frame; at least one wheel; and supports. The supports are arranged in a support frame movably connected to the main frame. The support frame comprises a seat sub frame and a leg sub frame. The seat sub frame or the leg sub frame is fixedly hinged to the main frame, and the other is displaceably hinged to the main frame. A transformation mechanism associated with the main frame can convert the device between a planar support state and an angled support state. Supports enclose an angle to define a seat and backing support. The leg sub frame is extended beyond its hinge relative to the main frame and comprises a set of wheels at the free end of the extended leg sub frame. The extended leg sub frame provides a sturdy wheel base in the angled support state to define a wheel chair mode.
