Jointly developed by Antonio Citterio and Vitra, the AC 5 Group is a family of task chairs designed to furnish modern, disparate office landscapes in a consistent aesthetic. Their trim shapes, sophisticated aluminium components and classic Hopsak cover fabric lend these chairs a dignified elegance. At the same time, the various models of the AC 5 Group cover a wide performance spectrum. These high-quality, versatile chairs are especially well suited for specific applications: from the ergonomically optimised task chair AC 5 Work and the reductive functionality of AC 5 Studio to the conference chair AC 5 Meet.

Contemporary office environments provide diverse settings in which employees can work alone or in groups as needed – whether at ergonomic single workstations or agile team hubs, in closed meeting rooms or informal interaction spaces. With its distinctive angled backrest, the AC 5 design becomes a unifying visual element in open-plan offices. It can either be used in a uniform version for an understated effect or with the wide range of Hopsak colours to create striking accents or form thematic groups.
