The Italian design chair can be stacked like standard seminar chairs (up to four chairs), but thanks to its seat shell you are better supported in your sitting position. The white basic model convinces with its excellent price/performance ratio, the robust seat shell made of heat-resistant polypropylene and its stable frame made of polished steel. Its extraordinary resilience is CATAS certified. The CATAS research institute tests the resilience, the load distribution on the seat backrest and the feet. A shock load test, the resilience of the front edge and signs of fatigue of the material are also tested, thereby guaranteeing a particularly durable piece of seating furniture.
