What kind of person thinks up a chair that looks like a chunk of coconut? How about the person who came up with the Marshmallow sofa. The person who said, "Total design is nothing more or less than a process of relating everything to everything." Who brought modernism to American furniture. George Nelson. 1950s. Call it what you will—classic, icon, slice of hard-shelled tropical fruit. Half a century later, it's as wonderful to look at—and sit in—as ever.
