These large 1m (40mm thick) interlocking safety mats are extremely popular to protect against hard floor areas in halls and gyms. Made from high-quality, closed-cell EVA foam, they are reversible and combine a smooth, soft touch surface (green) on one side, with a tatami weave effect (red) on the other. They are quick to lay as needed and can be stored away easily. Supplied with two removable straight edges per tile for a perfect finish!
