To start off I must say that I do love this rug, and would have given it 5 stars, however, completely and utterly disgusted, there are stains (alot) on the backing, picture does not show it that clear.  I purchased in April, and have been in process of redoing/redesigning my main bedroom and have just opened this purchase.  My fault for not unwrapping it when received, so at this point in time, I am unable to return it.  Appears to be pet stains, however, there is not a pet odor.  My guess is that it was a return item.  This will be my last purchase from Wayfair.
