The listed price includes one chair, and we have several available. The design features red leather upholstery, and has a steel base with a black finish. This is one of Sapper's most iconic works, along with the Tizio lamp. Each chair measures 26.5 inches long, 25 inches wide, and 36.5 inches high. It offers a pneumatic 4" seat height adjustment from 17" to 22.5". The leather has some small stains and it has creasing from use. The corners show wear. There are some scratches on base.
