This interlocking exercise mat set includes four tiles made from high-quality EVA foam, each measuring approximately 24 inches square and 0.47 inches thick. The durable foam provides cushioning for your spine, hips, knees, and elbows during workouts, yoga, stretching, or floor exercises. The textured surface offers slip resistance to help prevent injuries during physical activity or play. The water-resistant and noise-reducing properties make these mats ideal for home gyms, garages, fitness rooms, or children's play areas. Cleanup is simple with a damp cloth. The lightweight interlocking design allows you to quickly connect the tiles to create a custom coverage area, and they disassemble just as easily for compact storage when not in use. This product contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.
