mat

A mat is a piece of material, often made of woven, plaited, or felted fabric, used as a floor covering or support. Historically, early mats were likely made from interlaced fibers like grass or hair, with evidence suggesting weaving practices dating back to 6000 BC. Mats can also serve decorative purposes, such as a mat placed under a dish for protection. In sports, thick pads or cushions used for wrestling or gymnastics are also referred to as mats. Additionally, the term can describe a dense tangle of filaments, like an algal mat or a mat of hair. Some mats are even constructed from reinforced concrete to serve as building foundations. A specific type, a grass mat, is a woven material designed to simulate trimmed grass for displays or scenery.123
