This original M-chair or Artifort model F598, also known as the Groovy Chair, was designed by Pierre Paulin for Artifort in 1972. The chair, padding and upholstery, the original vermillion red woollen Kvadrat fabric, is still in very good condition, alltho the fabric is slightly looser under the legs. It has a tubular steel frame and aluminium glides on the underside, marked with the Artifort label. Nice organic design and also very comfortable. This piece has an attribution mark, I am sure that it is completely authentic and take full responsibility for any authenticity issues arising from misattribution
