Thanks to the technological prowess and fine craftsmanship of Knoll – today’s Butterfly has sinuous, dynamic lines, which are also made possible by the quality of the materials involved: the structure is in chromium-plated or coated steel, in white or black, while the seat is made with thermoformed felt. This element, in particular, represents the true innovation of the project, because thanks to its workmanship it becomes a self-supporting structure with the dual role of seat and covering. Furthermore, the laser shaping of the fabric, without added stitching, permits the direct interlock of the seat and the steel framework, ensuring comfort and elegance.
