"Herman Miller wanted a completely new chair and thus turned to the two designers who had produced the groundbreaking Equa chair and asked them to start with a clean slate and no assumptions. A bold challenge! "It was a matter of deliberate design to create a 'new signature shape' for the Aeron chair," says designer Bill Stumpf. "Competitive ergonomic chairs became look-alikes." Differentiation was a huge part of the Aeron design strategy, and it remains one of, if not the most, critical aspects of Aeron's success. "The human form has no straight lines; it is biomorphic. We designed the chair to be, above all, biomorphic, or curvilinear, as a metaphor of human form in the visual as well as the tactile sense. There is not one straight line to be found on an Aeron chair."
