    Abstract: One of the inventor's concepts is a furniture system comprising first and second articles of furniture and a hoist. The hoist raises the first article of furniture. The second article of furniture fits the freed space underneath enhancing its utilization. Another of the inventor's concepts is a freestanding frame to support a hoist that can raise an article of furniture. The system can be installed without the aid of a contractor and without damaging ceilings or walls. The frame can be a cabinet. A cabinet allows the furniture to be stored against a wall or as a room partition while hiding the stored furniture from view. These concepts can be used to increase the utility of a room. Multiple articles of furniture having different uses can be stored in one or more cabinets and or closets and selectively removed to adapt the room to one or another function.
