Works well - this rug is so long that it does shimmy to the side down our long hall way - but I just readjust. This pad was longer than the 16' or the rug was short...didn't measure, but we did cut about 3" off the pad to make it fit under the rug. Doesn't change my life, but if you need a rug pad I'm sure this is a good one :) - it's the only one I own, so not a rug pad expert by any means.
