BRUNE Sitzmöbel GmbH is a German seating and office furniture company headquartered in Königswinter-Oberpleis (North Rhine-Westphalia), founded in 1945 by Heinrich Brune as a household goods trading business. Wolfgang Brune introduced in-house production of kitchen benches, chairs and tables — initially in a former cinema studio hall in the Siebengebirge hills, from 1961 in the company's first own production building in Königswinter-Oberpleis, which remains the company's headquarters to this day. In the 1990s BRUNE acquired the former East German company ROTTA in Saxony-Anhalt from the Treuhandanstalt following reunification. In 2014 Andreas Fertig acquired all shares from the founding family and became sole shareholder; his wife Christina Fertig serves as authorised signatory responsible for human resources and marketing. The company philosophy: "Quality made in Germany" — coupled with exclusive collaboration with German designers.
