Abstract: A portable stair platform includes a planar member (i.e. a platform) having opposed sides and opposed ends. A first set of legs extends from a first end of the planar member and is movable between a first configuration generally perpendicular to the planar member (use configuration) and a second position generally parallel thereto (collapsed configuration). A second set of legs extends from an opposed end of the planar member. At least one set of legs is height adjustable. A wheel may be coupled to the planar member for easy transport of the device. The planar member includes a peripheral lip for holding items thereon. The stair platform may also include an extensible handle for operating the platform as a hand truck.
