The problem with putting a rug on carpet is that the natural nap in the rug and the nap in the carpet work against each other. Makes bumps like you wouldn't believe (even if no one walks on it). Furniture on top of the rug makes it worse.Does anyone else have this problem and if so have you been able to fix it, or at least minimize the bumps on the rug?
Dawn is right.. The special rug to carpet under layment ( its not really a pad).Its thin and feels tacky but leaves no residue. These underlayments are real thin and will pick up dirt naturally and loose their tackiness but you can toss them in the washer and they come back to work again. Some one will tell you to get the shelf liner material, this is not the same stuff and can leave marks.
You need to purchase a pad specifically for rugs on top of carpets. They are sold anywhere rugs are sold which includes Home Depot, Lowes, Bed, Bath Beyond and more. There are also pads for non carpeted floors so be careful to ask for the right pad. The pads come in defined sizes but can be cut to fit even the smallest rugs. They will keep your top rug from bunching and rolling and they are quite cheap.
