I ordered this rug because it described the material as a wool/polypropylene, which I interpreted to mean primarily wool.  It was priced comparably with other wool rugs I was considering, but more than I would have paid for a manufactured fiber rug.  When it arrived there was a card stapled to it that labeled the content at 80% polypropylene and 20% wool.  I called the manufacturer and confirmed the content.  Wayfair was very helpful and adjusted the cost somewhat to accommodate the discrepancy in the description.  I kept the rug because the color and style was what I wanted, but the material is not soft like wool.
