We will be replacing our carpet in our house and SmartStrand by Mohawk has caught our eye. I have a sample in my home so I am quoting from the back of the carpet. The style is 1168 Kinetic Contrast which I believe is a Frieze style. Pile is 100% SmartStrand BCF Triexta Made with Dupont Sorona. Color is 168 Natural Grain. We are dealing with a carept store not a Box Store (i.e. Home Depot or Lowes). The salesman has been very helpful but then again he is a "salesman" so sometimes I fear they tell you what you want to hear. We are looking at the shorter nap Frieze style. Does anyone have any experience with this carpet? We will be carpeting stairs so I am wondering how the Frieze performs on stairs. Thank You!
