The stool, a seat with no back and no armrests, is the earliest form of seat. It can be either three-legged or four legged, in plain wood or in silk covered giltwood. In the court of Louis XIV it was a status symbol to be brought a stool in the presence of the king. Many stools have specific purposes such as the spinning stool or the piano stool and can be of adjustable height. The 20th C Art Deco style stool and the vintage Tolix stool in metal are highly sought after for the modern home.
