Furniture (probably from the French 'fournir' — to provide) is the mass noun for the movable objects ('mobile' in Latin languages) intended to support various human activities such as seating and sleeping in beds, to hold objects at a convenient height for work using horizontal surfaces above the ground, or to store things. Storage furniture such as a nightstand often makes use of doors, drawers, shelves and locks to contain, organize or secure smaller objects such as clothes, tools, books, and household goods. (See List of furniture types.)

Furniture can be a product of 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.
