We had decided to purchase a new, larger rug for our living room. We actually liked the look of the rug we had, so we ended up ordering the same rug, just in a larger size. The one complaint we had about our old rug was that it was not comfortable to lay on- mostly because of the thin pad we had and the fact that it is on hard wood (with concrete subflooring).
After doing some hunting around, we gave this rug pad a try. I'm glad we did! It shipped quickly, was easy to cut (they even offer to send you a custom size for free!) and has made the new rug so much more comfortable to lay on! It does leave a small bump around the perimeter of the rug, but that is to be expected with a pad of this thickness. I would gladly take the small bump for the extra comfort.
Definitely worth the price!
