One way to add visual interest to a room and make it appear larger is to place your furniture at an angle. This arrangement works best for rectangular dining room tables, beds in square bedrooms, sofas and desks. Placing furniture at an angle works because the longest straight line in any given room is its diagonal. When you place your furniture at an angle, it leads the eye along the longer distance, rather than the shorter wall, making the room seem larger. As an added bonus, you often get some additional storage or display space behind the angled piece.
