Karl Dittert for Martin Stoll / Giroflex office chair, likely 1970s. This later version is distinguished by its larger, smoother-rolling casters, suitable for use on a wider range of floor surfaces. While remaining faithful to the original design — featuring a shaped wooden shell, black leather upholstery and an aluminium base — this example reflects a subtle technical evolution within the series. The chair is swivel-mounted and height-adjustable, offering practical comfort for everyday use. The wooden shell is in very well-preserved vintage condition and features a beautiful natural grain. The leather shows light signs of use and a warm patina consistent with its age. Comfortable, considered and timeless in character.
