Responsible, innovative and beautiful, eva represents the most efficient and effective combination of materials and design thinking we’ve ever put into a task chair.
Workplace design can play a significant role in improving employee health, happiness and productivity, and can hold the key to attracting and retaining a talented workforce. The workplace is constantly changing, and with fewer dedicated workstations and more shared collaborative workspaces the way we work is evolving from sitting in one chair at a desk all day every day to working across multiple locations in shorter bursts. At the same time, the demographics of the office environment are broader than ever before.
Our latest task chair, eva, upholds our commitment to lead by example in environmentally responsible product design and manufacture, while placing a greater emphasis on user experience and comfort.
In fact, we let the chair make many of the adjustments itself: a self-weighing mechanism intelligently responds to the user’s weight, automatically providing the right amount of resistance as they recline in the chair. No adjustment necessary.
The optional travel limiter means the chair can be locked in the upright position, or, for a more personalised set up, be set at three different angles of recline. Refining the chair to just a few controls has allowed us to focus on maximising the range of adjustment it offers, and as a result, eva caters for a larger percentage of user demographic, reducing the need for specialist occupational health chairs.

Eva`s mechanism responds to the user’s weight, automatically providing the right amount of resistance.
Eva's optional air-cell lumbar offers adjustable support for a more personalised set-up.
100mm of button controlled height adjustability and our signature rotating soft-touch armpads make these the most functional armrests that we offer as standard.
