The backrest and seat of the rollingframe 52 are made of extruded aluminium and give the office chair its harmonious structure. The armrests are also delicately curved, underlining the lightness of the construction. The seat width of the height-adjustable chair was increased by 10 per cent in the course of the development and offers an optimised seating comfort. The five-star base with castors provides stability. The covers are made of polyester mesh and are optionally available in fabric or leather.
