The design of Eero Saarinen's Executive Armchair with Casters (1957) began more than a decade earlier, when he and Charles Eames submitted several designs to the Organic Design in Home Furnishings competition at MoMA. The pair, who'd been friends and collaborators since meeting at Cranbrook Academy of Art, won first prize. These fluid, sculptural shapes influenced the future work of both men â€“ for Saarinen, most notably in his Wombâ„¢, Tulipâ„¢ and Executive Chairs. The Executive was originally made of fiberglass but was later updated in polyurethane. The feel of this classic seat, however, remains unchanged, with a molded shell that flexes slightly with the sitter and a contoured plywood seat. Unlike Saarinen's furniture, which was consistently sculptural in form, these fluid lines didn't appear in his architecture until the 1950s. When looking at the dome-shaped glass wall of the Kresge Auditorium at MIT, it's not a big leap to see the same shape in the back of his Executive Chair. This chair is Greenguard Indoor Air Quality Certified for its use of low-emitting products. Manufactured by Knoll according to the original and exacting specifications of the designer. Backed by a five-year manufacturerâ€™s warranty. Made in U.S.A. The Executive Armchair with Casters is supported by a five-point, pneumatic height-adjustable swiveling base with twin-wheel casters for use on carpet.
