Set of original SZ01 armchairs by Martin Visser, for Spectrum, 1965. These chairs have a brushed tubular steel frame and a natural saddle leather seat and armrest finish. Beautiful minimalist and timeless design. With use, the leather only gets more beautiful. On 1 chair the back and 1 armrest is dark discolored, probably due to moisture. Obviously only visible when chair is free standing. However, as a bonus, a free extra seat is included! (The leather can also be dyed very well (e.g. black - the other color in which these chairs were originally made by Martin Visser - if done by a specialist).With use, the leather only gets more beautiful.
