I purchased this rug based on the description as a WOOL rug.  When I received the rug, the manufacturers product information shows the content as having 75% Polypropylene/25% Wool.  You should not advertise this as a WOOL RUG when the majority of the fiber content is Polypropylene.  I find that very misleading and very disappointing. I felt this rug was a bit more expensive but based on the fact that I thought I was purchasing a wool rug, I went ahead and bought it.  
Birch Lane should consider how they are advertising their products.  Call it what it is and not mislead your customers.
