Though I'm not a mathematician by trade, I still believe that the Royalton Sofa ($9,335) — designed by Philippe Starck in 1991 — can be expressed by the following formula: Settee + Headboard = Royalton. The ever-resourceful and always surprising Starck is responsible for many unique designs, including my fave, the Louis Ghost Chair.
Of course, I'm more likely to spend 10G on my garden than on this piece of furniture — let's face it, if your dog secretly jumps on your sofa, it's never a good idea to drop a lot of money on such a royal piece. However, a girl can still dream, right? The Royalton, a few Louis Ghost Chairs, a luxurious rug . . . my dream living room's out there somewhere, even if it's only in my imagination.
