Textured carpet is a more polished-looking carpet, with a sheen you don't see with frieze due to textured carpeting having more even-length yarn pieces in its cut pile. Frieze, on the other hand, is more nubby and casual looking. You should choose frieze for settings that are more laid back, like a den, for example, or a kids' play room. Textured carpet will dress up any room in the home, visually, making it ideal if you're more concerned with appearance.
Frieze trumps textured carpeting in regards to durability due to its heavier yarn twists. The tighter and thicker the yarn twists, the more durable the carpet. Textured carpet can be durable too, but its cut pile has fewer yarn twists, so it doesn't compete as well with frieze on this level. Frieze carpeting can withstand rougher and heavier traffic, so consider the amount of foot traffic you expect in the home when choosing between the styles of frieze and textured carpet.
Textured carpet will keep looking fresh in spite of your busy household, as it is made to hide the appearance of footprints with its two-tone color pattern. This two-color look helps with minimizing the walk patterns you and your guests will see, so you can use it throughout your home. In addition, this carpet type will help hide those vacuum marks you might typically see on your carpet after cleaning. Frieze carpet, on the other hand, merely minimizes footprint patterns; it doesn't hide them like textured carpet does.
Run your hand over a textured carpet and it will feel much like a man's buzz haircut -- short, even and firm. Run your hand over frieze carpet and a shaggy dog might come to mind. Textured carpet can hold plates and drinking glasses more firmly if they are placed on this carpet flooring type. Expect spills if you do the same thing on frieze carpet due to the varying yarn twists and lengths.
