A sofa table can look nice and be useful in more than just the space behind a couch. If you don't have much floor space, a sofa table can be used as a buffet, an accent table, a desk, a vanity, a TV stand, and more. Not only are these tables useful in the living room, but they can also be used to decorate empty hallways and stairwells by giving paintings, photos, lamps, and other keepsakes a place to stand.
