Design by Eero Saarinen, 1957. By Knoll. In his groundbreaking collection of 1957, Eero Saarinen transformed executive seating into a fluid, sculptural form. Recognizing the importance of user comfort, Saarinen became the first to construct a chair shell from fiberglass, a pliable material that flexes in response to body weight. Saarinen's classical training in sculpture and architecture is evident in this visually striking open back chair. The Saarinen Executive Chair with Tubular Legs has seamless tubular steel legs with a Polished Chrome finish and glides. Features a molded reinforced polyurethane shell and contoured plywood seat form. The urethane foam cushion is upholstered with matching full surround welt detail. The Saarinen Executive Chair with Tubular Legs features seamless tubular steel legs in a Polished Chrome finish. The seat is offered in a range of KnollTextile fabrics and Spinneybeck leathers.
