The support units are each of an elastic extendable/retractable arrangement. When the step board is treaded down, the operation bars provide a torque in a way similar to a seesaw and the support units provide an elastically-support upward-pushing effect to raise up the seat unit so as to allow a user, with or without the assistance of an attendant person, to rise and stand up easily.
