Greatmats Home MMA and BJJ mats are designed for the grappling arts at home. They provide cushioning for takedowns and throws and feature a double sided, double color no-burn tatami surface. The tiles are reversible. The interlocking tiles are easy to install by simply pushing them together. Cut them to fit for wall-to-wall installation, using a sharp utility knife. The tiles are 2x2 feet in size and 1 58 inch thick. Each tile comes with two border strips, allowing you to create a finished perimeter edge. They are made of polyethylene and EVA materials that will not absorb moisture. Clean with a damp mop using mild floor cleaner.
