A commode is any of many pieces of furniture. The Oxford English Dictionary has multiple meanings of "commode". The first relevant definition reads: "A piece of furniture with drawers and shelves; in the bedroom, a sort of elaborate chest of drawers ; in the drawing room, a large kind of chiffonier." The drawing room is itself a term for a formal reception room, and a chiffonier is, in this sense, a small sideboard dating from the early 19th century.
