mat (noun)- A piece of wrestling equipment where the match itself takes place. Regulation High School and collegiate mats range from a 32'x32' square up to 42'x42' square and are either 1" or 1.25" thick. Inside all square mats are two concentric circles one 24' and one 10' in diameter these serve as the boundaries for the match. The mat is made from a foam material, which, on a personal note, appears soft but is actually rigid when you get tossed on it. =)
