Overview

Topstar GmbH is a German seating manufacturer based in Langenneufnach near Augsburg, Bavaria. The company produces roughly 2.5 million swivel chairs per year at its Langenneufnach site, which places it among the top three office chair manufacturers in Germany and among the top ten worldwide according to German Wikipedia. Its product range spans office chairs, ergonomic seating, gaming chairs, kids' furniture, living and outdoor seating, and hospitality seating, marketed under the umbrella brand Topstar and the sub-brands Sitness, Sitness Urban and Sitness RS. The company traces its roots to 1949, when Moritz Wagner, grandfather of the current management generation, began building a factory for wooden chairs at what is today the Topstar site in Langenneufnach. He supplied local joiners and later the first furniture retailers. His development of the cone plug connection for gas springs in swivel chairs laid the foundation for the company's later focus on swivel chairs. In 1976, Michael and Christine Wagner founded Topstar GmbH, which together with their three sons Rainer, Michael Jr. and Peter Wagner grew into one of the largest manufacturers of office swivel chairs. Today Topstar operates under its corporate brand name and, since 2006, also builds premium office chairs under the original Wagner brand. The company positions itself around the claim "Sit, Move, Improve" and the concept of "New Work – New Sitting", emphasizing ergonomic design, movement-promoting seating and German manufacturing. Its website highlights AGR-certified collections (Aktion Gesunder Rücken, the German campaign for healthier backs), a fabric collection, designer collaborations, and a factory outlet (Werksverkauf). Product highlights named on the official site include Airhop High, Airhop, Sitness RS X, AirWork Meeting 20, AirWork Meeting 10, AirWork Sitness, AirWork Soft, Sitness Art, Sitness 4D, Sitness 3D Stool, Sitness Life 40 and Sitness X Back Pro. Topstar remains a privately held, family-owned German company. Its brand architecture combines the corporate Topstar brand with the Sitness family of product brands, and it serves office, home, gaming, kids, hospitality and outdoor segments.

History

The history of Topstar begins in 1949, when Moritz Wagner, grandfather of the current management generation, started building a factory for the production of wooden chairs at the site in Langenneufnach near Augsburg that is still used by Topstar today. He supplied local joiners and later the first furniture retailers such as Möbel Krügel and Quelle. Moritz Wagner continually developed new production technologies to improve the durability of his products, and with the development of the cone plug connection for gas springs in swivel chairs he laid the foundation for the company's later production focus on the swivel chair for the next generation. In 1976, Michael and Christine Wagner founded Topstar GmbH. Together with their three sons Rainer, Michael Jr. and Peter Wagner, the company developed into one of the largest manufacturers of office swivel chairs. According to German Wikipedia, Topstar produces around 2.5 million swivel chairs per year at its Langenneufnach site, making it one of the top three office chair manufacturers in Germany and one of the top ten worldwide. Today Topstar GmbH operates under its corporate brand name and, since 2006, has also built premium products in the high-quality office chair segment under the original Wagner brand. The company's brand architecture now includes the umbrella Topstar brand alongside the Sitness, Sitness Urban and Sitness RS product brands, and its portfolio has expanded beyond classic office seating into gaming, kids, living and outdoor, and hospitality applications. The official website presents the company under the guiding idea "Sit, Move, Improve" and the "New Work – New Sitting" concept, and highlights AGR-certified collections, a fabric collection, designer collaborations, a factory outlet and a range of highlight models such as Airhop High, Airhop, Sitness RS X, AirWork Meeting 20, AirWork Meeting 10, AirWork Sitness, AirWork Soft, Sitness Art, Sitness 4D, Sitness 3D Stool, Sitness Life 40 and Sitness X Back Pro.
