The Kartell Stone Stool designed by Marcel Wanders has a gem-like symmetrical linear shape, reminiscent of an hourglass. Its surface is simply extaordinary: an irregular myriad comprised of geometrical facets which reflect the light and create a striking unique play of colors, much like a diamond. The Stone Stool is made of window-clear polycarbonate, is strong and rigid, scratch and weather resistant, and suitable for indoor and outdoor use. Because of its jewel-like nature, Stone is offered in the colors of the precious stones.
