Hard Bottom Dog Car Seat Cover for Trucks – Back Seat Extender
Long drives are more comfortable for your dog when the back seat feels like a floor, not a gap. This hard bottom seat cover bridges the space between your truck’s back seat and the front seats, creating a flat, stable platform where your dog can stand, sit or lie down – while your upholstery stays protected from fur, mud and claws.

A flat, stable platform
A thick poplar plywood board inside the base keeps the surface flat with no sagging, even when your dog shifts around. It is rated to support up to 400 lbs.
- Hard bottom back seat extender with a thick plywood board.
- 7-layer build: 600D cationic fabric, PVC waterproof coating, padded cotton layers, 210D Oxford cloth and a non-slip rubber mesh bottom.
- Waterproof and scratch-resistant surface against fur, mud, drool and claws.
- Mesh viewing window so you can see your dog and air can move between front and back.
- Storage pockets for leashes, treats and toys.
- Easy to clean: wipe or vacuum the surface; the cover is machine washable.
