Elementi Rug 250 cm X 250 cm by Rolf Benz250 cm X 250 cm, 70% Pure New Wool 30% Tencel; with Grey Brown (346) by Rolf Benz RUG WITH THE BEST PROPERTIES OF NATURE. Pure fleece wool is always the new wool shorn from a living animal and is therefore a sustainable raw material. The especially resilient natural fibres also impress with properties that make for an excellent rug. Fleece wool is dirt repellent, elastic, sound insulating and, unlike synthetic fibres, barely absorbs any odours. Rolf
