These two chairs come from a time in Austrian design where craftsmanship and design are combined with the best materials to make beautiful furniture. Cherrywood and walnut were used only in the bests designs. The seating uses coil springs and is upholstered with a high quality fabric. The shellac is in wonderful 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
