Evo, by Burkhard Vogtherr and Jonathan Prestwich, is a modern take on a Davis classic. Based on the concept of the Motion chair designed by Burkhard Vogtherr in 1987, Evo is a new evolution of the traditional executive chair built for the 21st-century workplace. The geometry of the chair is designed so that the user acts as a counterweight for the movement of the seating mechanism. Breaking down the components of Evo, the back, seat, and armrests were designed to be elegant and visually quiet but to come together with a perfect balance and flow. Evo features beautiful flowing lines and a simple elegance that speaks volumes.
