The fiber used in a carpet will determine its wearability. The more you know about fiber, the easier it will be to choose the right carpet for your home.

Nylon: Nylon particularly type 6 is the strongest, most durable and most widely used fiber. The soft texture holds its color well, resists most food and beverage stains and many oil-based stains, and is easy to clean.

Wool: Wool carpets are warm and durable, but can be damaged by alkaline cleaning detergents. They're also available in fewer shades because they don't take bright color dyes well.

Polyester: These carpets are reasonably durable, but some are more susceptible to oil-based stains.

Polypropylene: Polypropylene carpets are moisture resistant and are available in a limited selection of colors. They also lack bounce and resiliency in all but the most dense constructions.

Padding
While you're shopping, don't overlook the value of carpet padding. A good pad will increase the lifespan of any carpet. The cushion will soften your walking surface, as well as insulate for heat and noise, and prevent the carpet from sliding.

Padding is available in several different materials, including foam rubber and urethane. In terms of pad density, choose cushioning based on how the room is used. Rooms subject to heavy wear and traffic will require a dense pad, while rooms with lighter use can get by with something softer.

Be sure to verify that the pad is water resistant or its color may bleed up through the carpet if it gets wet.
