carpet

A carpet or rug is a textile floor covering that typically consists of an upper layer of pile attached to a backing. In Europe, the pile was traditionally made of wool, but since the 20th century, synthetic fibres such as polypropylene, nylon, and polyester have been used as cheaper alternatives. The pile often consists of twisted tufts that are heat-treated to maintain their structure. The terms carpet and rug are used interchangeably, although rugs are generally loose-laid and smaller. Since the 19th century, there have been trends to produce fitted carpets, wall-to-wall carpeting for rooms that are fixed in place. Read more on Wikipedia
