Abstract
According to the present invention, there is provided a retractable staircase for a recreational vehicle. The retractable staircase has a translational section, which includes at least one-step. The translational section moves between an extended and a retracted position relative to the recreational vehicle. In the extended position, a rotational section, which also includes at least one step, moves between a lowered position with the step below the step of the translational section and an upside down and inverted position above the step of the translational section to provide for movement of the translational section to the retracted position.
