Tables come in a wide variety of materials, shapes, and heights dependent upon their origin, style, and intended use. Many tables are made from wood or wood-based products, although glass tables are also used. Most tables are composed of a flat surface and a base with one or more supports (legs). A table with a single, central foot is a pedestal table. Long tables often have extra legs for support.
Table tops can be in virtually any shape, although rectangular, square, round (e.g. the round table), and oval tops are the most frequent. Others have higher surfaces for personal use while either standing or sitting on a tall stool.
