Abstract: An inclinable stairway for providing a staircase in one orientation and a ramp in another orientation comprising a pair of spaced, opposed, and upwardly extended side walls, each side wall having opposed and upwardly extended front and rear edges with an inclined edge extended upwardly from the front edge to the rear edge in a stair-step fashion; a pair of spaced, opposed and articulated upper support members, each upper support member having a lower end and an upper end with the upper end pivotally coupled to the top edge of a side wall, each upper support member comprised of a linkage of elongated bracing elements pivotally coupled end-to-end with the bracing elements in the linkage aligned along the inclined edge of an adjacent side wall to define a staircase configuration, and the bracing elements in the linkage linearly extended above an adjacent side wall from the top edge thereof to a location adjacent to the base plate to define a ramp configuration; a plurality of step members coupled to alternating
