The fluent organic lines of the cast aluminum frame are only interrupted by the tapered teak armrests offering a warm design element. The seamless integrated curved backrest plate has two X-shaped openings. They not only serve as aesthetic features but also as fixation points for the backrest cushion. These are attached by means of X-shaped knobs that come standard in the color of the frame. Teak ones are also offered as an option to match the armrests. They make the Exes chair even more of an eye-catcher.
