Two of the biggest mistakes you can make when placing your furniture are: 1) Placing all of your furniture against the walls, and 2) designing around electrical outlets. Allow your room to breathe by pulling your furniture away from the walls. In fact, floating furniture in the middle of the room creates a sensation of spaciousness. Meanwhile, surround sound, wireless electronics, docking stations and many other technological advances have liberated homeowners from having to work around outlets.
