The 3D MAXpider cargo liner is a custom-fit, single-piece behind–third-row seatback protector for 2020–2021 Mercedes GLB-Class seven-seat models. Its digitized three-layer design conforms to cabin contours to contain spills and debris, while raised edges and a waterproof top layer protect cargo areas. Patented MAXpider backing secures the liner without harming original carpet; materials are non-toxic, foldable for access, and easy to clean.
