Furniture is the mass noun for the movable objects which may support the human body (seating furniture and beds), provide storage, or hold objects on horizontal surfaces above the ground. Storage furniture (which often makes use of doors, drawers, and shelves) is used to hold or contain smaller objects such as clothes, tools, books, and household goods. Furniture can be a product of artistic design and is considered a form of decorative art. In addition to furniture's functional role, it can serve a symbolic or religious purpose. Domestic furniture works to create, in conjunction with furnishings such as clocks and lighting, comfortable and convenient interior spaces. Furniture can be made from many materials, including metal, plastic, and wood. Furniture can be made using a variety of woodworking joints which often reflect the local culture.
A range of unique stone furniture has been excavated in Skara Brae a Neolithic village, located in Orkney, Scotland. The site dates from 3100-2500BC and due to a shortage of wood in Orkney, the people of Skara Brae were forced to build with stone, a readily available material that could be worked easily and turned into items for use within the household. Each house shows a high degree of sophistication and was equipped with an extensive assortment of stone furniture, ranging from cupboards, dressers and beds to shelves, stone seats and limpet tanks. The stone dressers were regarded as the most important as it symbolically faces the entrance in each house and is therefore the first item seen when entering, perhaps displaying symbolic objects, including decorative artwork such as several Neolithic Carved Stone Balls also found at the site.
