A "mat" is a flat piece of material, often made from fabric, rubber, or plastic, used for various purposes. Mats can serve as protective surfaces, provide comfort, or enhance safety in different environments. Common types include doormats, which help keep dirt out of homes, and yoga mats, designed to provide grip and cushioning during exercise. Mats are also used in sports, such as gymnastics and wrestling, where they provide a safe landing surface. In addition, car mats protect vehicle floors from dirt and wear. Overall, mats are versatile items found in many settings, contributing to cleanliness and safety.
