Eero Saarinen vowed to address the ugly, confusing, unrestful world he observed underneath chairs and tables -- the so-called "slum of legs." A five-year design investigation led him to the revolutionary Pedestal Collection, including the Tulip Stool, introduced in 1958. The Saarinen stool has an upholstered cushion on a swivel base. A nameplate with the KnollStudio logo and the signature of Eero Saarinen is located on the underside of the base. The base consists of cast aluminum with Rilsan coated finish for the white and black versions. The Platinum base has a polyurethane coat with a transparent finish. The base is available in black, white, or platinum colours.
