A couch, also known as a sofa, settee, futon, or chesterfield (see history of the term below) is a piece of furniture for seating two or three people in the form of a bench, with armrests, which is partially or entirely upholstered, and often fitted with springs and tailored cushions. Although a couch is used primarily for seating, it may be used for sleeping. In homes, couches are normally found in the family room, living room, den, or the lounge. They are sometimes also found in non-residential settings such as hotels, lobbies of commercial offices, waiting rooms, and bars.
