To prevent rugs from creeping on fitted carpets:
The Oriental Rug Merchant recommends Cybergold Rug Underlay.
Best for… on fitted carpets, can also be used on hard floors.
Cybergold Rug Underlay is an innovative dual purpose Rug Underlay that works not only on fitted carpets but also an be used to prevent slipping on hard floor surfaces. This material is thin and fleece-like and is slightly tacky to the touch, so sticks to the carpet/floor underneath and grips the rug on top.
This needs to be under the entirety of the rug to work effectively.
Price: £10 per metre – off the roll (roll width is 3′ 3″ or 1.00m).
