I rated this 3 star only because I could not use it. We just put wood look vinyl plank flooring on our basement floor and wanted a pad for under our area rug. This pad was better quality than others we bought, so we were very disappointed to read on the bag that it could not be used on vinyl, lacquered wood floors, tile, etc. I had never noticed other pads saying that. I reread the description on the web site and it says for use on" hard floors." We thought our floor was a hard floor, but feared to use the pad because of the warning on the bag about vinyl. The return was easy and Customer Service promised to clarify that in the description on the product on the web site. Different floors require different kinds of padding.
