This 45x53-inch chair mat features a rectangular shape with a lip extension, designed specifically for low-pile carpets up to 1/4 inch thick. Made from durable PVC, it resists curling, cracking, and fading while protecting your carpet from chair wheels, scratches, and wear. The 0.1-inch thickness provides reliable floor protection. The mat includes 5mm anti-slip studs that dig into carpet for superior grip, preventing shifting during use. The textured surface allows chair wheels to glide smoothly while reducing noise. It's free from BPA, phthalates, and volatile toxins for healthy indoor air. The transparent design lets your carpet show through while maintaining a clean professional look.
