We just got in the "third generation" of SmartStrand Ultra with DuPont Sorona. You will love these new styles and colorations, as well as the denser and softer hand of these beautiful carpets. Did you know with SmartStrand Ultra you have 69 fashion forward colors to choose from, plus the strongest warranties in the industry? SmartStrand Ultra with DuPont Sorona carpets feature lifetime stain and soil resistance, 25 year texture retention and full pet warranties, plus are transferable to the next homeowner. We did not think it was possible, but the best just got better!
