I am replacing carpet on my stairs and after looking at a few places I am totally confused. Since stairs are high traffic what is a good brand and kind to get. I was thinking a nylon berber with a tight loop. What is good face weight and density? Need inspiration pics. Thanks!
Contrary to popular opinion, berber is not a good option for stairs. True berber does not have a tight twist to the yarn, in fact sometimes it has almost no twist at all. A short plush or textured plush will wear better. If it's a loop carpet you're after, look at a commercial weave.
Nylon is the work horse of carpet fibers, so on that point you have been given some good advice. Shop at a carpet store vs. a box store. You will get far better information, a better price and a quality installation.
