get ready for a tremendous amount of work when you get this rug. it is loaded with dirt and the smell is overwhelming.  we ordered a huge size and are still vacuuming and turning, vacuuming and turning just to get all the dirt out of it.  we covered it with baking soda and vacuumed all of that out of it to reduce the smell but it took days for that to go away.  I have never received a rug in this condition, ever.  it is not the "natural fibers" that are the issue.  it is dirt.  disgusting dirt.
