Grappling Puzzle Mat, part of inter-locking mat system, is a quick, easy, and affordable way to mat your entire floor. It is made of a 6lb density EVA foam in a 40" x 40" interlocking tile dimension, and is completely waterproof. Each mat is double-sided (double color) and truly reversible, and every order comes complete with border strips. This mat is designed specifically for MMA and grappling arts such as Judo, Jiu-Jitsu, Aikido and Hapkido. The 1 5/8" foam protection provides a safe and comfortable surface for throws and takedowns. The mat also features a tatami-textured top surface simulating the surface of the high quality Zebra Tatami-style Grappling Mat. The interlocking seams are very tight and will virtually disappear once installed.
