As written on this product review on the 2x12 runner, we are very happy that we spent the extra money on these rug pads. They are absolutely perfect for their versitility in being able to use on wood or hard surface floors, with the option to use either the 'grabber-side' or the padding side, depending on your floor style. And the depth or height of the pad, isn't so thick that you stub your toe entering the rug area. We are very pleased and highly recommend this product.
