Unix Chair
Antonio Citterio, 2010

The Unix Chair is the ultimate all-rounder for office environments. It can be used behind a desk as a task chair or in front of it as a visitor chair. Unix is available in different versions that are ideal for conferences and meetings. And it is suited for touchdown workstations as well as waiting areas. The chair's structural design and the innovative padded mesh cover ensure a high level of comfort. Thanks to a wide range of colour options, it works equally well in sleek, functional office settings and in more expressive and personal work environments.
