Even if your living room is tiny, it's wise to fit in at least three places to sit. For the third seat, I would choose something hard (i.e., not upholstered) but with arms, so it still feels comfortable to sit in for longer periods. Rather than let it float in the room, pull your extra chair up to a cute little desk so that it can do double-duty. My pick is based on a classic Windsor chair, but it's updated with a fresh dip-dyed paint job. — Laura Gaskill
