Environmentally friendly, modern, and versatile. The Saarinen Executive Armchair with Swivel Base from Knoll was a big hit when it was first introduced in 1950, and it changed the way people looked at executive seating. Eero Saarinen was excited by the idea of creating chairs where the shape of the shell, rather than the thickness of the cushions, gave comfort. The molded, reinforced polyurethane back works with the contoured plywood seat to achieve this goal. The simple and smooth shape of this product gives it versatility, complementing a range of established decors.
