Anti-slip rug underlay is recommended for rugs placed on polished floors to prevent slippage and movement with foot traffic. The underlay has the added benefit of affording protection for polished timber floors that can after some time show scuff marks from where rugs have continually moved.
Rug2u.com.au offers several sizes. Simply choose the size slightly smaller than the rug it will be placed under. The anti-slip underlay is also easily cut to size to fit runners and smaller rugs. Each box contains several sheets.
