A living room piece is a type of furniture that is used to provide seating in a living room. The four most common types of living room pieces are the SETTEE, DIVAN, SOFA, and OTTOMAN. A SETTEE is a small couch with a back and two arms, usually upholstered. A DIVAN is a long, low couch without arms or a back, often used as a daybed. A SOFA is a large, upholstered couch with a back and two arms. An OTTOMAN is a low, upholstered seat with no arms or back, often used as a footrest.
