Mats and liners are essential interior accessories that protect your vehicle's carpets from wear, tear, and spills. They come in various materials, including carpet, rubber, and thermoplastic olefin (TPO), each offering distinct advantages. Carpet mats provide a luxurious feel and can trap dirt, while rubber and TPO liners are more durable and easier to clean, perfect for handling wet and muddy conditions. Consider factors like your climate, driving habits, and desired level of style when choosing between these options.
