Felt rug made of the finest merino wool. The wool is felted by machine and thus has an enormous hold and is absolutely robust. A carpet made of the renewable resource virgin wool is not only insulating and warming for the winter, it also provides a pleasant indoor climate. Virgin wool has a natural self-cleaning function. It positively regulates the indoor climate in a natural way and draws dirt out of the air due to its antistatic properties. The natural, renewable raw material virgin wool is naturally environmentally friendly, colorfast and flame retardant. Wool carpets have the property that they initially lose excess wool fibers from the production process (fluff). This is a natural process that quickly disappears with regular vacuuming and walking on the carpet.
