I have a carpet and a hall-runner which both slip constantly on the carpet underneath. My sister has bought products which have not worked, so I am wondering if any of the answerbank readers can give me any sound advice on things they have used which do work, as rucked rugs/ carpets provide an elf and safety hazard.. .
Try the 'hook' part of sticky backed Velcro. Stick this to the underside of your runner and re-lay. Just try a small piece to start with. I found it far better and cheaper than expensive
anti-slip underlays.
