A chair is a type of seat, typically designed for one person and consisting of one or more legs, a flat or slightly angled seat, and a back-rest. It may be made of wood, metal, or synthetic materials, and may be padded or upholstered in various colors and fabrics.Chairs vary in design. An armchair has armrests fixed to the seat; a recliner is upholstered and features a mechanism that lowers the chair's back and raises into place a footrest;a rocking chair has legs fixed to two long curved slats; and a wheelchair has wheels fixed to an axis under the seat.The chair has been used since antiquity, although for many centuries it was a symbolic article of state and dignity rather than an article for ordinary use. The chair is still used as the emblem of authority in the House of Commons in the United Kingdom and Canada, and in many other settings.Chairs can be made from wood, metal, or other strong materials, like stone or acrylic. In some cases, multiple materials are used to construct a chair; for example, the legs and frame may be made from metal and the seat and back may be made from plastic. Chairs may have hard surfaces of wood, metal, plastic, or other materials, or some or all of these hard surfaces may be covered with upholstery or padding.This is made in zbrush and it is used for 3d printing only.
