This rug has worked out very well. It has a rubberized bag and is weighty enough that is did not require a pad or additional backing. It is also a great price for the size I needed. My only concern is that it still has not yet flattened out -- it arrived folded -- has still has creases that make it a little bumpy. I am hoping this eases over time. Other than that, terrific and it arrive on time and well-packaged.
