The Collection E visitor and conference chairs are for universal application. When arranged formally, they can be integrated into the most diverse environments, permitting problem-free combinations with existing furnishings. The one-piece seat shell provides a pleasant sitting sensation, and is available in the fully-upholstered or exposed wood shell version. All chairs are equipped with armrests, offering a choice between leather and plastic armpads. The back-friendly cantilever typically shows the pronounced curvature of the forward edge of the seat. The practical reason: no pressure is exerted above the hollow of the knee, even during long periods of sitting. The formal reason: the convex radius provides a matching counter-part to the concave curvature of the seat shell.
