Originating in France as the "fauteuil confortable", the "comfortable armchair", the club chair has mysterious origins. No one is quite sure of who first designed it or when, but it has since become an interior design staple. The Art Deco era produced armchairs with clean, flexible lines, in contrast to the Art Nouveau style of the 1910s. After World War II, dozens of different shapes appeared. Some have stood the test of time, such as the "moustache" and the "gendarme’s hat", named after the shape of the backrest. The round shape has become the club armchair’s most emblematic incarnation.
