We are replacing the upstairs carpet in our new house. The upstairs requires 1,086 sq ft of carpet. The actual stairway has 14 stairs (11 small, 3 large) and the master bedroom is also 12.5' wide (most rolls are 12'). Both of us prefer a nylon-based, dense (and soft) textured carpet. Durability is critical because I want this to last at least 10 years, but I recognize that soft and durable tend to work against each other. Keep in mind that we do not plan to have pets and shoes are not worn in the carpeted areas. We looked at Fabrica, but the s/o felt the material was a bit too rough. Currently, we are considering: 1) Karastan Live Artfully - $7.29/sq-ft installed, including taxes and fees. Uses a Karastan BCF Nylon with Scotchgard. Uses a hard backing. 2) Shaw/Anderson Tuftex - $7.69/sq-ft installed, including te es and fees. Uses a Stainmaster Luxerell BCF Nylon, presumably a 6.6? Also uses a soft backing. Note: both quotes were with an 8lb waterproof pad with a memory foam. The Shaw/Anderson feels a bit rougher than the Karastan but I am willing to consider this option if there is a significant durability advantage. I am also open to all other options, price is not really the concern is - value/durability are. Any help would be greatly appreciated. Thank you.
