Design firm Herman Miller first launched its popular Aeron chair in 1994. Designers Bill Stumpf and Don Chadwick replaced the foam and fabric of traditional office chairs with high-tech materials and cutting-edge design. Over seven million Aeron chairs have been sold in 134 countries. Now, Chadwick has overseen a redesign of the chair. He told DnA why the redesign was needed and why it's important for designers to work with their hands.
