Antique furniture is the term for collectible interior furnishings of considerable age; often its age, rarity, condition, utility, or other unique features makes the furniture desirable.

Antique furniture may support the human body (such as seating or 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. Cabinetry and cabinet making are terms for the skill set used in the building of furniture.

The earliest furniture was understandably very primitive and only practical, but gradually the furniture also began to have more importance and it became decorated. At this point, furniture became an early status symbol. Wealthy homeowners became more refined and demanded that their furnishings reflect their status and lifestyles.
