Save a sheep a haircut and buy P.E.T. Polyester. This inexpensive wool alternative is environmentally friendly, has built-in moisture and stain resistance, is colorfast and feels incredibly soft. Made from recycled P.E.T. products, like plastic soda bottles, polyester carpets are stronger than Olefin and can perform as well as nylon at a much lower cost. Polyester offers a way to enjoy a soft, plush carpet at a very affordable price.
