This SZ02 Armchair was designed in 1960 by Martin Visser. The pure material, the clear construction, and minimalist design are typical of Visser's work. The armchair has a slim tubular brushed steel frame, and a thick black leather cover. The leather is in good condition and has a beautiful patina. I have official proof of authenticity such as vintage catalogs, designer records, or other literature sources and take full responsibility for any authenticity issues arising from misattribution
