Deep enough to form a comfortable seat and shallow enough to balance a cup of coffee  Ethat’s how Ray Eames described the depressions on the ends of this sculptural stool that she and Charles designed. That ingenious versatility paired with its geometric good looks and outstanding craftsmanship have made it a go-to in lobbies and living rooms around the world. First introduced in walnut in 1960 as Eames Walnut Stool, its new name reflects the addition of ebonised ash and the process still used to manufacture the stool.
