In addition to the classic chrome versions of the base and armrests, the metal parts of the ID Chairs are also available in the colours soft grey and basic dark. The soft grey hue gives the chair a decidedly non-technical appearance, and combined with light-coloured fabric or leathers has a friendly inviting look. In these light-coloured palettes, the ID Chair is also ideal for the home office. And if the metal parts are selected in black, in combination with dark fabrics or leathers, the dark monochrome chairs acquire a striking silhouette.

Human beings have a natural urge to move – even while seated. Ideally, an office swivel chair should not only offer freedom of movement but also encourage dynamic sitting habits. With this in mind, Vitra developed the FlowMotion mechanism. This patented mechanical unit supports the sitter across the full range of movement – not just in the backward tilt, but also when leaning forwards. Nearly all functions can be adjusted while sitting in the chair, and just a few quick turns of an adjustment screw enable precision tuning from minimum to maximum resistance. Even if the settings are not optimally adjusted on occasion, the chair still retains its ergonomic properties.



The functional features of the FlowMotion mechanism come in three different combinations:

• with forward tilt, without seat depth adjustment
• without forward tilt, with seat depth adjustment
• without forward tilt and without seat depth adjustment

Vitra Test Center
Vitra has its own Test Center where all office chairs undergo rigorous testing to simulate 15 years of use. Vitra's inspection catalogue includes the world's toughest tests (simulation of worst-case usage), with requirements that far exceed standard regulations. Over the years, Vitra has developed additional tests of its own that are not found in any official catalogue of standards.

Blue Angel
The ID Chair Concept bears the 'Blue Angel' environmental label for low-emission upholstered furniture, which certifies that the manufacturing methods and materials of the product comply with guidelines for environmental protection and consumer safety. The Blue Angel (1978) is one of the oldest environmental labels.

GREENGUARD
The GREENGUARD label for indoor air quality (2001) recognises products that contribute to the creation of healthier indoor environments.

GS
With the GS seal for tested safety, a state-authorised inspection institute certifies the suitability and safety of the construction and monitors production at regular intervals.

Ergonomics Approved
The LGA certificate 'Ergonomics Approved' confirms the fulfilment of ergonomic requirements and testing criteria that exceed the minimum legal regulations for office swivel chairs.

BIFMA
ID Chair fulfils the ANSI/BIFMA standard X5.1-2011, thus meeting the stringent safety requirements for the US market.
