While couches take up a fixed amount of space, a pair of chairs adds almost as much seating and endless combinations. A pair of chairs can be used to complement a sofa (or pair of sofas) in a U shape, like what is seen here. To shake up the look, use one couch and a pair of chairs on the opposite side or, for a larger room, position the chairs in an L shape in relation to the couch. Whichever configuration you choose, a pair of chairs is a versatile addition to the decor.
