A car trunk tray with extended matting, also known as a cargo liner, is a protective mat that covers the entire floor area of your car's trunk or cargo area. It is made from a durable and waterproof material, such as rubber, thermoplastic elastomer (TPE), and is designed to protect your trunk from dirt, spills, and scratches.
Extended matting refers to a cargo liner that goes beyond the standard trunk floor and extends up the back of the rear seats. This provides additional protection for your car's interior, especially if you fold down the rear seats to haul cargo.
