It does what it is supposed to do. Holds the rug from slipping and wrinkleing especially important when vacuming. Gives enough padding to let rug breath and feel a bit softer to walk on. All the things that incrrease the life of the rug. I have it under a rug that can be flipped over and I hope the pad will keep the underside nice by raising it off any dust or debris that doesn't get caught by the vacume.
