I have a very long runner rug in my kitchen. I bought the typical under pad (cushioned) for it. It has never held my rug in place and it really irritated me. I paid a lot of money for it. Now enter this firm grip dual surface non slip pad, and perfecto!! It holds my rug in place without issue and I’m beyond grateful!! It’s thin but very tacky and works exactly as it says. I’d definitely recommend this to anyone looking to hold a rug in place. Even large rugs!
