These cantilever B20 chairs were designed 1980s and manufactured by Tecta, Germany. The chairs have a cantilever style base, constructed from polished chrome, with a high backed seat. Constructed from hand woven beige cane. 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
