This is the best pad for the money! It may be the 'deluxe' model and not the 'superior' one, but I can't imagine why someone would pay more for the higher grade pad. This pad keeps my large rug (over hardwood floors) in place, with no shifting or sliding whatsoever. Unless someone has an extremely high pile with high density rug, I feel this mid-range pad will do the job just fine. This is the second pad of this type that I've purchased and I highly recommend it. I am having more hardwood installed (in place of carpeting) so will be ordering more of these pads for the other 8 or 9 wool area rugs that I own.
