A model "Oase" chair, designed by Wim Rietveld for Ahrend de Cirkel in 1958. The chair is newly upholstered using blue rib fabric, on a grey metal frame and black bakelite armrests that are not damaged. In good condition. 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
