Your choice of rug padding should always reflect the utility you need added to your carpet most, and not personal desire or what sounds nicest. The choice of the carpet can often be a long and complicated process for many, and the choice of the rug pad is often similarly complex. This is not only due to the large variety of materials used for making rug pads, each with its own set of pros and cons, but also the use that the rug pad will be seeing. The material more often than not directly determines the quality of the rug pad as well as what the rug pad can be used for.When looking into buying carpets, calculate exactly how many carpets you will get and what their size will be. The rug pads need to match the carpet's exact size, so if you are getting an 8 x10 carpet, know that you will also need an 8 x10 rug pad. Once the size and quantity have been determined, consider the price of all the rug pads combined. Try not to have it exceed your budget while also ensuring the quality is up to a certain standard. The larger the rug pad and the better the material, the steeper the price. Rug pad thickness is also another factor potentially increasing the price.There are rug pads that do more harm than good, and those are often rug pads with which saving money is the primary concern. The worst of this bunch is the free rug pad offered by the rug vendor, as these are infamous for causing the carpet to sustain more damage than it would even without a rug pad. While it can be tempting to forgo the cost of a larger rug pad, like the 8 x10 rug pad, try not to think of it in such a way. If you use a free rug pad to save money and it damages your carpet, you accomplished the opposite effect you actually lost money because you will have to replace the carpet much sooner. This means you are much better off paying a little extra up front for a quality rug pad than paying several times its price in the not too distant future. Urethane foam rug pads are another type of rug pad that can often be detrimental instead of providing the carpet with benefits. Because of the very cheap materials used to manufacture these, as well as the manufacturing process being focused on reducing the cost and mass-production, these pads lack in quality and have a good chance of staining your carpet beyond repair. If you are getting a rug pad for your home, it's likely it will be under a carpet that you intend to use for years, if not decades. This only becomes possible if the correct rug pad was chosen, as carpets, especially those under a lot of traffic, can be very vulnerable to wear and tear. It's not just about the quality of the material, but also its compatibility with the specific carpet you will be using it for. Check with the rug manufacturer to ensure there isn't a mismatch between the carpet and the rug pad you are getting.
