The ACX support mechanism naturally adapts to the user's weight. The only manual adjustment required is the seat height. Ideally, the user's knees should be at a 90 degree angle. This position allows the synchronization mechanism to function optimally and also improves blood circulation in the legs.

How it works: Lever on the underside of the armrest When in the correct position, the armrest relieves pressure on your shoulders and prevents muscle strain. Adjust the height of the armrest to the approximate height of your desk surface so that your elbows are bent at approximately a 90° angle.

Vitra develops products and environments
Vitra elevates the quality of homes, offices and public spaces through the power of design. Founded in 1950 and since.

Product and environmental developmentRespect for the environment is expressed in every aspect of Vitra's activities: in the way we develop and manufacture our products, the way we source our raw materials and the way we organize our supply chains. New discoveries lead to further developments. Vitra believes that the environment "shapes" how we think and feel. With the power of design, we work every day to make the environment better.
In developing products that can be used for as long as possible , we avoid short-term trends and eliminate unnecessary elements. If the design, manufacturing method, and materials are not all in place, the product will not last.

Materials Vitra complies with official certification programs for sustainable and responsible sourcing and is committed to using materials that meet human rights and environmental standards. Products and materials are regularly analysed and assessed by external organisations. 46% of Vitra's suppliers are German and 96% are European. As a globally active company, we produce our products in the most resource-efficient way possible and deliver them to our customers all over the world.
Cultural Activities <br>Vitra is also active in the cultural sector beyond its business activities. It invests a large portion of its profits in preserving cultural heritage in design and architecture, and supports various institutions around the world, such as the Eames Foundation, which preserves the Eames House in Pacific Palisades, California, the Alvar Aalto Foundation in Finland, and the Barragan Foundation in Switzerland.
Furthermore, the Vitra Campus, located on a vast site in Weil am Rhein on the Swiss-German border, is a one-of-a-kind experimental space for architecture and design, and a place where architecture, design and art are open to everyone on an equal footing. The ongoing development of the Vitra Campus is also a sign of our mutual, long-term relationship with the region of Weil am Rhein.
