Back Up Your Furniture "Floating" furniture makes for a great floor plan, but it leaves a wide expanse of boring sofa-back in the open. Use that dead space to your advantage: -- Slip a slim glass-top console behind the sofa for a small home office area. -- Search thrift stores or flea markets for a chair that slides easily beneath the table. (Hint: Paint it a vibrant color.) -- When entertaining, stash the chair against the wall and use the desk as a food buffet.
