Not wool! Do not buy.Tried to return, but Wayfair refused to pay for return shipment despite false advertisement from the rug company. Wayfair required me to show them proof that it is not wool even though the carpet had no label to indicate what type of materials. Did some researched and took pieces of the carpet fiber and burned it.It melted and clump together like nylon. Shared the article and requested that Wayfair tested out themselves, but has not received any response. Do not buy from them.
