It took a few days for the roll marks to come out of the carpeting.  Wayfair did not have any rug pads to purchase that fit this size runner.  My cats think this runners, I bought two, are great new toys to push around the floor.  The pattern is very nice, but the feel and smell of the rungs are very synthetic smelling.  I have had the rugs for about two weeks, and the smell is disappearing more each day.
