The design of Eero Saarinen's Executive Armchair (1957) began more than a decade earlier, when he and Charles Eames submitted several designs to the Organic Design in Home Furnishings competition at the MoMA. These fluid, sculptural shapes influenced the future work of both men; for Saarinen, most notably in his Womb, Tulip and Executive chairs. The Executive was originally made of fiberglass but was later updated in polyurethane. The molded shell flexes slightly with the sitter and the contoured plywood seat supported by metal or wood legs. Unlike Saarinen's furniture, which was consistently sculptural in form, these fluid lines didn't appear in his architecture until the 1950s.
