The "Model T60" studio or workshop chair is strongly reminiscent of the "Chaise d'Atelier" by the French architect, engineer, and designer Jean Prouvé (1901-1984). However, it is a design by the Swedish metalworking company Odelberg & Olson AB from the early 1940s. The chair has clearly seen decades of use and therefore exhibits a pronounced patina. It would be a shame to alter it. We have thoroughly cleaned the chair, oiled the plywood parts, and ensured the various functions are working correctly. Sharp-edged veneer chips have been smoothed and repaired. The seat height can be continuously adjusted from 53 cm to 66 cm. The backrest angle can also be individually adjusted. The backrest panel is movable and comfortably adapts to any back shape. I have official proof of authenticity such as vintage catalogs, designer records, or other literature sources and take full responsibility for any authenticity issues arising from misattribution
