Rug pads are ideal partners for your area rugs. They not only prevent your area rug from sliding and slipping on hard surfaces but they also extend the life of your rug by providing a smooth, supportive base. They also look after your hardwood floor, prevent them from being scratched and abrasion. They allow your rugs to breathe and moisture to evaporate, preventing mildew and making vacuuming easy. This layer is usually very thin and does not add too much to the overall thickness. Some wonderful products come from Mega Lock, Rug Lock, Stay Put, Tiger Grip, Persian Dream, and Super-Loc.
