Do you often find yourself putting your back seats down to make room for pets, gear, groceries and more? WeatherTech's SeatBack Cargo Liner HP safeguards the base and up the back seats of your vehicle's cargo area, even when the seats are down! This cargo liner is made from the same heavy-duty, rubber-like material as our bestselling FloorLiner HP, offering a durable one-piece mat that defends against spills and messes. Its patent pending expandable accordion hinge allows you to put your back seats in the full-down position and maintain uninterrupted coverage - no more spills or pet hair adhering to the back of your seats or cargo area! There's even a specially designed water retention ribbing system that helps trap water. SeatBack Cargo Liner HP defends against the dirt, grass, mud, and debris that come from workout gear, dogs, sports equipment, groceries, or anything else you put in your cargo area. Non-slip nibs on the underside - and hook fasteners - keep this trunk liner in place - both on the floor and up the backs of your seats. Plus, because it's a one-piece mat, installation and removal for cleaning is easy. Have young kids? No problem! SeatBack Cargo Liner HP features a trimmable outline to accommodate attachments for child car seats - known as ISOFIX - while the cargo mat stays in place. Made from a thermoplastic elastomer, this cargo mat offers the flexibility and durability needed for maximum protection. It won't break down in extreme weather, and is 100% recyclable with no latex, PVCs, cadmium or lead. Enjoy high-performance, full coverage and protection for the bottom and seat backs of your cargo area with the American-made SeatBack Cargo Liner HP.
