Definitely no wool in this rug. I did a fiber burn test     Wool does not melt into a ball. If it is wool it chars and smells like burning hair.   There are other mistakes in the product description.  This does not weigh 2 pounds as stated, more like 20.  As far as stating that it is machine washable I can’t even imagine how large a machine would be required to fit the rug.  It looks nice and it’s the right color so I’m keeping it but a very misleading product description
