An office swivel chair with a flexibly mounted backrest for better comfort.
Design: Burkhard Vogtherr
The Diagon swivel chair's hallmark is its aluminium backrest support. While it appears at first glance to be a decorative design feature, it does in fact serve different functional purposes. The support has two lateral pendulum joints with rubber cushions onto which the backrest of the Diagon is flexibly mounted. This construction offers the advantage of dynamic sitting: The pendulum joints ensure that the reclining movement is in perfect sync with the user's body and they widen the opening angle of the seat and back. Matching cantilever chairs complement the swivel chair as visitor or conference chairs.

Burkhard Vogtherr

Born in 1942, between 1972 and his death in 2019 Burkhard Vogtherr ran a product design agency. He worked for prestigious furniture manufacturers the world over, was one of the most famous German furniture designers, and won multiple awards during his career.
His expertise in areas such as sitting posture at work and movement sequences was incorporated in his designs for swivel chairs and conference furniture. However, Burkhard Vogtherr did not restrict himself just to form and design – he developed prototypes that stand in their own right. This often resulted in highly inventive furniture leading to patents across the globe.
