With the technological process for molding plywood resolved, Charles and Ray applied the method to the design of domestic furniture. After an exhaustive program of prototyping and testing, the first product was a simple plywood chair with both the seat and back supports gently curved so as to ergonomically and comfortably accommodate the human body. It was produced by the Herman Miller Company of Zeeland, Michigan, and marketed as an affordable, multifunctional chair suitable for all modern households. Known as the ECW (Eames Chair Wood) model, this chair is still in production today, and has exerted a profound and lasting impact on twentieth-century furniture design in America.
