The Topstar executive chair RS1 combines sporty seating comfort with a high-quality appearance and is suitable for office workstations, meeting rooms and reception areas.

Thanks to the backrest and contoured seat with lateral shaping, the seat shell provides noticeable support during prolonged sitting periods.
