Designers

Bill Stumpf Bill Stumpf once said that he liked to collaborate with other designers the way a jazz trio improvises, playing together with no fixed destination. The approach requires complete attention, and you have to trust your instincts. "Design should make room for spontaneity and discovery" said Stumpf.

Don Chadwick Chairs are for sitting on. It sounds obvious, but there are designers who seem to miss that point. Not Don Chadwick, however, who has developed some of the best chairs on the market – including the Aeron Chair with Bill Stumpf – by emphasising the body and the fact that bodies move.
