If you're going to put a lot of money into carpeting your home, you want it to last. That's why you should choose a carpet that's durable enough to handle a room's intended use and possible foot traffic. Like comfort, durability is dependent on the style of carpet and the fiber with which it is manufactured. Loop pile carpets are the most durable because there are no open ends, making it less likely to pull or shed. Nylon, Olefin (polypropylene), and wool resist wear and tear much better than other fibers, like acrylic and polyester.
Although it's an afterthought for many buyers, padding is actually an important part of your carpet's durability. In addition to cushioning your feet and insulating your house from cold and noise, this sub-layer can increase the life of your carpet, if installed properly. Different carpets call for different padding thicknesses, so be sure to check the manufacturer's recommendation before tacking anything to the floor.
