Find carpet retailers in your area that offer nylon carpet. Most general retailers should have a large selection of samples, because nylon is a popular carpet option.
Feel the various nylon carpet options. Nylon is known for being soft. But the softest option might not be the right one for you. For example, you may be using the carpet in a basement, where durability is important. The tighter the carpet fibers are woven, the stiffer the carpet will feel.
Check to see if the nylon carpet you want to buy is solution-dyed. Solution-dyeing differs from other processes, because the dye is added during the production of the fibers. This means that the fibers are colorfast and will not fade over time.
Find out if the nylon carpet you're considering is branded or unbranded. Branded nylon carpet is usually stain resistant, while unbranded may not have this feature, according to "Consumer Reports." Although carpet made by little-known companies may be cheaper, you might want to stick with better-known manufacturers that can provide stain-resistance guarantees.
Factor in the price for the various types of nylon carpet. Although price should not be your main consideration, you do need to think about it. Generally, you can buy nylon carpet for about $14 to $30 per square yard.
