Charles and Ray Eames, American industrial designers, designed the DAR Chair in 1948. After World War II, the United States was looking for low-cost furniture. Charles and Ray looked at technologies developed during World War II, including fiberglass, a plastic reinforced by glass fibers, to understand how they could incorporate it into their designs. The DAR chair resulted from this investigation, and it consisted of a one-piece fiberglass seat attached to metal legs. It was one of the first plastic chairs to be put into mass-produced.
