The aim behind the structural design of AC 4 was to discreetly integrate the functional elements required for optimal comfort. Up until now, the design of office chairs has emphasised either their aesthetic appearance or their functional features. By contrast, the integration of ergonomic features in AC 4 is so subtle that its sophisticated structural compo- nents remain concealed. It achieves a balance between the most advanced ergonomic functions and an unobtrusive appearance: the innovative technical features of AC 4 are neither put on display, nor are they hidden beneath foam padding. AC 4 is an emblematic object with an elegant appearance and uncompromising functionality, ideally suited for refined offices and conference spaces.

AC 4 is available as an office swivel chair and in the version AC 4 Conference for meeting venues.
