Vintage Dutch design arm chair

This chair was designed by gerrit rietveld in 1918, unfortunately not an original so made after his design, which is quit common. More commonly known as the red blue chair. This has never been painted from what I can see. All beech wood from what I can tell. Its very well made and sits remarkably comfortable. Condition is good, used but not abused. Measurements are ca: 65 cm wide X 87 cm high sku: 302124l.
