Wall-to-Wall Carpet Buying Guide

Previously called olefin, polypropylene is a solution-dyed synthetic that is both water- and stain-resistant, making it a good choice for indoor/outdoor carpeting. Because it is solution-dyed, it will not fade, making it good for rooms that get a lot of light or traffic from the outside or from a cholorinated pool. Because it is less resilient than nylon, it is best used in low-pile carpets such as berbers (low, loop-pile carpeting with flecks of different colors).
