When a rug is walked on, there is pressure to push through the rug and hit the floor. A quality rug pad will act as a barrier between the carpet and the floor to prevent any scratching from the back of the rug to the floor. Therefore, the carpet pad should be solid as opposed to one with holes in it. The more solid and dense the pad, the better the protection to the hardwood floor.
The next pad is one that has a non slip feature for rugs that tend to move around, mostly rugs size 6'x9' and under. This pad is a dense needle punched recycled jute surface with a natural layer of solid rubber backing. This is the pad that is textured on the surface to grab your rug and the rubber holds everything to the floor. It is 1/4 of an inch thick and extremely dense. Use this safely on all floors as long as you get one with a solid rubber and not a sprayed on latex that can harm floors.
Another important function of a rug pad is to find one that will work on top of carpet flooring. Putting a rug on top of carpet is very common. But rugs tend to move and buckle a lot when over carpet. We looked at all of the rug pad types and found the best rug pad for using over carpet is the rubber backed felt rug pads. The installation needs to be the reversed from when using with hard surface flooring. To properly install over carpet, put the felt side to the carpet and rubber side of the pad against the rug. It is amazing how effective this product is for using over carpet.
