Overview

Design by Antonio Citterio, 2008.
By Vitra.

With innovative technology that is neither showy nor hidden, the AC 4 Task Chair creates a balance between advanced ergonomic functionality and subtle design. Three-zone comfort includes an integrated lumbar zone, a flexible zone for the upper back that reduces tension and pressure on the discs and straightens up the neck and head, and a supportive shoulder zone which keeps the neck muscles relaxed, making it easier for the user to maintain a horizontal view of the screen.

The AC 4 Task Chair features a synchronizing mechanism, with large opening angle and automatic weight adjustment of the backrest resistance, ensuring that the user's weight is supported in every sitting position. The polished die-cast aluminum base and fixed ring armrests add an element of elegance and sophistication. Available with casters or glides.

Vitra's AC 4 Task Chair has been awarded the Blue Angel eco-label and is also GREENGUARD Certified. AC 4 is made of up to 51% recycled materials and can be re-recycled up to 94%.

Vitra

Manufacturer: Vitra

Classic. Modern. Sustainable.

Vitra has manufactured furniture designs by Charles & Ray Eames and George Nelson since 1957. Building on this foundation, Vitra has developed a wide range of furnishings for the office, for the home and for public spaces in collaboration with progressive designers. Yet Vitra is more than just a design-oriented manufacturing company. The name also stands for the Vitra Design Museum, for a collection of modern furniture and its accompanying archive, for workshops and publications on topics of design, and for an architectural concept that unites buildings by Frank Gehry, Nicholas Grimshaw, Zaha Hadid, Tadao Ando, Alvaro Siza, Herzog & de Meuron and SANAA at the Vitra Headquarters in Birsfelden (Switzerland) and on the Vitra Campus in Weil am Rhein (Germany).

Product longevity is central to Vitra's contribution to sustainable development; short-lived styling is avoided at all costs. This can be seen most clearly in the classical pieces of furniture that have been used for decades, had several owners and have then even ended up as a part of a collection. For Vitra, the manufacture of sustainable products means intense pre-production development, where the highest-grade materials are selected and tests are carried out that simulate 15 years of use. In order to enforce and monitor sustainable development in all business activities of the company, a work group was formed in 1986 by the name of 'Vitra and the Environment'. Because of this, Vitra can proudly claim that it has been dedicated to sustainability for nearly a quarter of a century.
