Seat, usually with four legs and a back, intended for one person. It is one of the most ancient forms of furniture, dating to the 3rd Egyptian dynasty (c. 2650–2575 BC). Various styles were developed throughout Europe. In the 16th century, many chairs began to be covered with upholstery over padding and decorated with elaborate wood carving. U.S. chairs adapted versions of English styles from the late 17th century.
