Decorating a room around a white sofa requires a contemporary design that exemplifies modern elegance. A white couch isn't practical for pets or young children, so it's best suited for a living space used primarily by adults. Incorporate soft, muted wall colors and contemporary accessories into the room, so your white sofa stands out as a focal point in the overall design. White is a neutral, clean color so you can choose warm or cool accent colors to complement your living space.
