Rearrange What You Already Have
Rearranging the furniture you already have is probably the least expensive way to give your living room a new look. Move your sofa from the far wall to the middle of the room. Bring in that red chair from the bedroom for a splash of color and some extra seating. Trade the area rug in the bedroom for the one in the living room. You'll be surprised how much these simple changes will refresh the look of your space.
