An elevator system (2) includes a hoistway (4) extending between a plurality of landings (8) and an elevator car (6) that is movable in the hoistway (4) between the plurality of landings (8); landing doors (10) provided at the landings (8); and at least one storage cavity (30) provided at at least one of the landings (8) for accommodating a mobile working platform (50), that is configured to be set up in the elevator car (6). The at least one storage cavity (30) is formed in a wall (24) of the hoistway (4) and/or in a landing door frame (26) provided at the respective landing (8).

A platform assembly is provided with at least one foldable and deployable handle. The handle can be operated to a storage position lying between upper and lower surfaces of the upper platform of the assembly. When deployed, the handle can provide a handhold, top cap, and other features to users who are on the upper platform or who are climbing onto the upper platform. Leg assemblies of the platform can be operable between folded and deployed states, and feet of the leg assemblies can be deployed to widen the stance of the platform or folded to reduce the overall width and volumetric envelope within which the platform resides.

A hybrid sawhorse has a first pair of legs connected to a first bracket and a second pair of legs connected to a second bracket and a head connected to and extending between the first and second brackets. The head is reversible, having a top with a channel therein extending parallel to a length of the head and having a bottom having a groove extending perpendicular to its length, such as for accepting workpieces in different orientations. The legs are extendable, such as to defined locked positions. The sawhorse may include spaced hooks, such as for use as a cord wrap, and may include at least one bracket located at an end of the head, such as for accepting and supporting a piece of lumber.
