The problem with this product is only that an annoyingly significant amount of carpet fibers is released every time it is vacuumed. I have vacuumed this thing at least 10 times already. I don't know if all wool rugs do this, or just this particular material from this manufacture does? I read other buyers said the same thing about this rug & I was hoping it wouldn't be the case with me. Now I'm looking for another large rug for my other room, but I sure wouldn't buy this again.
