Designed for CLS 257 2019, 2020, 2021, 2022, and 2023 CLS C257, this custom-fit trunk liner delivers complete rear cargo protection with an exact shape that aligns perfectly with the original trunk floor. Crafted from durable, odorless PE rubber, it offers a waterproof, anti-slip surface that guards against spills, dirt, wet gear, and wear from daily use. The raised edge perimeter contains messes and prevents liquid or debris from seeping into the carpet, while the textured surface helps reduce cargo movement while driving. Built for year-round function, this mat stays flexible in freezing conditions and resists warping under heat. It installs instantly with no trimming and cleans easily with a damp cloth or hose, providing dependable all-weather defense for drivers who want clean, protected storage space with minimal effort.
