Why is there such a big difference in price between the cheapest and most expensive carpets?
The price difference arises because of differences in quality, including such factors as: the fiber material of which the pile is made; the density of the pile; the length of the pile above the backing; the finished weight of the pile; the number of colors woven in, the nature of the pattern, and the degree of colorfastness; treatments applied to the fiber, to the backing or to the finished carpet to improve attributes such as fire resistance, staining resistance, and freedom from static electricity. As when buying any other product, you only get what you pay for!
