When seeking the best performing carpet, never sacrifice the type of fiber/yarn used. As a rule of thumb, carpets labeled “BEST” are thicker, tighter weave, and made from highly twisted EnVisionSD™ PetSolutions Nylon & EnVision™ Nylon fibers. These carpets stay beautiful and last the longest. Remember when you buy any of these carpets at Premier Flooring Center, ALL stains are covered in all parts of your home.
