Non-Slip Underlay – RUGSA rug is woven to last generations. The least we can do is give it good ground to stand on. Our non slip underlay is the quiet layer between your rug and the floor the one nobody notices, doing all the work. It stops the slipping and the curled edges. It softens every step. And it protects the underside of your rug from the slow friction that wears fibres thin over time. Safe on timber, polished concrete, tile and stone. Pre cut to size, no tools
