Charles and Ray Eames believed that â€œdesign is a method of action,â€ and they continually updated their work as new materials became available. Their Molded Plastic chairs were originally designed in metal and entered as a prototype in MoMAâ€™s 1948 International Competition for Low-Cost Furniture Design. They then changed the material to fiberglass in 1950, and today the chairs are made of recyclable polypropylene. Charles was dissatisfied with the fiberglass, and it wasnâ€™t until after his death that the matte finish he desired was achieved, thanks to advances in materials. â€œThe chair that Charles and Ray were designing,â€ explains grandson Eames Demetrios, â€œis the chair thatâ€™s made tomorrow .â€ The deep seat pocket and waterfall seat edge keep you comfortable by reducing pressure on the backs of thighs. This is an authentic chair by Herman Miller, Inc. Eames is a licensed trademark of Herman Miller. Made in U.S.A. DSW stands for dining height, side chair with wood base.
