Smartstrand carpet (aka Triexta) is a fairly new addition to the carpet world. This type of carpet has built-in stain and soil protection thereby creating a more durable, family friendly carpet. It is luxuriously soft, yet very sturdy. One thing to note about this fiber type is that while it is resistant to natural spots and stains, it can attract oily soils so regular maintenance and proper fabric protection are key to getting the most life from your investment.
