Furniture refers to movable objects intended to support various human activities such as seating (e.g., chairs, stools, and sofas), eating (tables), and sleeping (e.g., beds). Furniture is also used to hold objects at a convenient height for work (as horizontal surfaces above the ground, such as tables and desks), or to store things (e.g., cupboards and shelves). 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. It 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.
All different types of woods have unique signature marks that can help in easy identification of the type. Both hardwoods and softwoods are used in furniture manufacturing, and each has their own specific uses. Most commonly, quality furniture is made out of hardwood which is made from oak, maple, mahogany, teak, walnut, cherry and birch. Highest quality wood will have been air dried to rid it of its moisture.
