This sheepskin is gorgeous! The product specifications on the website are wrong in many instances. This product does not have any “Polyester, Latex, Other” backing material; the material type is not “Knotted”. It is just one plain old genuine sheepskin. Very generously sized and the pile is much thicker than the pile on other sheepskins I had. The skin itself is maybe on a stiffer side, but I can still use this sheepskin over a chair and it conforms to the shape of the chair easily. I am so glad I bought it!
