The back, you know, is the most important part of your body. I’m never tired at the end of a day—never. It’s because of the way I sit. At the Metropolitan Museum I have the same kitchen chair I used to have at Vogue. They sent it to me because nobody else would ever use such a hideous-looking thing in their swell offices—but it supports me at the base of my back, and that’s what’s important. Then, I have a little rubber cushion which gets me right at the end of my spine and keeps me straight up, up, up. Everyone who comes into my office at the Metropolitan thinks the cushion looks a bit medical—well, it is; you buy it at a drugstore—but for me, it means that I sit straight and high, and it’s marvelous.
