Aluminum Group chairs began as a challenge among legendary designers. Eero Saarinen and Alexander Girard were designing the Columbus, Indiana, home of industrialist J. Irwin Miller. They wanted a high-quality seating product for outdoor use and asked Charles and Ray Eames to develop one.

Known for their honest use of materials, the Eameses constructed their chairs with cast aluminum and a seat frame meant to support a stretched synthetic mesh. The seat-back suspension was a major technical achievement and represented a departure from the concept of the chair as a solid shell.
