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.[1][2] Although a couch is used primarily for seating, it may be used for sleeping.[3] 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.
