A Windsor chair is a chair built with a solid wooden seat into which the chair-back and legs are round-tenoned, or pushed into drilled holes, in contrast to other styles of chairs whose back legs and back uprights are continuous. The seats of Windsor chairs are often carved into a shallow dish or saddle shape for comfort. Traditionally, the legs, stretchers, and uprights (or spindles) were usually turned on a pole lathe. Spindles may also be carved, using drawknives and spokeshaves. The back and sometimes the arm pieces (if present) are formed from steam bent pieces of wood. Traditional Windsors are typically painted, primarily to hide the different types of wood used in construction, based on their characteristics.
