This "Swing" bar stool was designed in 1982 by Jutta and Herbert Ohl for Rosenthal. It is made of white powder-coated metal. Due to its construction, the seat feels like a cantilever chair. The bar stool is in very good vintage condition. This piece is attributed to the mentioned designer/maker. It has no attribution mark and no official proof of authenticity, however it is well documented in design history. I take full responsibility for any authenticity issues arising from misattribution
