Hi Kerri, Thank you for your enquiry. The Kick Mats fasten to the back of your seat with two attachment points at the top and bottom for a secure fit. Measuring 44.45cm by 57.15 (H x W), the large mats offer full coverage for most vehicle seats. The mats are made with water-resistant fabric protecting against muddy footprints on your vehicle seats. Plus, they are easy to wipe clean and are machine washable in cold water with mild detergent. They are a tightly woven fabric which seems very durable, such as the type of material that would be in a raincoat. We hope this has helped with your query.
