Ruff Liners Standard Back Seat Extender for Dogs – Gray | 400 lb Support, Waterproof, Hard Bottom Platform

Overview

Ruff Liners Standard Back Seat Extender for Dogs in Gray transforms a cluttered back seat into a roomy, stable platform for canine companions. With a solid hard bottom and generous dimensions (52.4" L × 24.8" W × 21.7" H), it bridges the seat gap to create a flat, accommodating space for lounging or multiple dogs on longer trips. The design supports up to 400 lbs and includes firm inserts to help keep the base steady, even with active pets. The 2025 update adds an expansive storage pouch behind the driver’s seat for quick access to toys, waste bags, and essentials within reach.

Why it works for road trips

Beyond space, the extender emphasizes durability and ease. The triple-layer surface resists water, mud, and fur, making spills easier to manage. When pets settle in, the cabin tends to stay cleaner, and the flat surface simplifies cleanup after a drive. A patented door panel protection feature helps shield interior panels from scratches, drool, and paw prints mile after mile.
