Though I'm not a mathematician by trade, I still believe that the Royalton Sofa [1] ($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 [2].

Of course, I'm more likely to spend 10G on my garden [3] 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 [4] . . . my dream living room's out there somewhere, even if it's only in my imagination.
