he top rail and both arms are longer than the distance between posts, thus named “four protruding ends” (or “Sichutou” in Chinese Pinyin). This official’s hat armchair is one of a pair. Its top rail, arms, four posts and three horizontal supports below are all round sticks. The back is slightly bent backward while both rear legs are bent forward, forming two arc shapes opposite to each other, which is fairly ingenious. The arc-shaped apron under the seat is flat and straight. There is no side posts under arms. Overall the design is simple and plain, but quite graceful.
