Which of the following best describes tufted floor coverings?

Tufted floor coverings are characterized by their construction method, which involves the use of a backing material onto which yarns are pushed through to create a pile. This method allows for multiple layers, often including a backing layer, a cushion, and a face yarn that creates the surface texture. The presence of a face yarn is essential, as it defines the pile's appearance and feel. This layering system not only contributes to the aesthetic qualities of tufted floor coverings but also affects their durability and comfort.

The other descriptions do not accurately capture the full essence of tufted floor coverings. While some tufted carpets can be decorative, describing them as woven is misleading because tufting is not a weaving process. The notion that they are made with only one type of fiber is also limiting, as tufted carpets can incorporate various fibers such as wool, nylon, or polyester, depending on the desired characteristics. Lastly, tufted floor coverings are not primarily used in upholstery; they are mainly utilized as area rugs or wall-to-wall carpeting.
