Antonio Citterio collaborated with Vitra to develop different versions of the ID Visitor chair, perfectly coordinated with the ID Chair Concept. Thanks to an understated design, they can be combined with almost any office chair and integrated in a wide variety of work environments.ID Visitor Air has a particularly light and graceful appearance thanks to its slender plastic backrest. The perforated back allows for flexible movement and good air circulation, while offering targeted support. The seat padding is optionally available in a more sustainable PU-free version, and the cantilever base is stackable.
