ROUWINNE Back Seat Extender for Dogs – Large Space, 420 lb Load, Waterproof Truck Hammock

Give your dog a safer, more comfortable ride with the ROUWINNE Back Seat Extender for Dogs. Designed for full-size crew cab trucks, this sturdy shield creates a generous space in the rear that can help keep anxious pets settled during trips and make cleanups easier for you.

Expanded space and secure footing

When deployed, it expands to 59 inches in width and 28.74 inches in depth, covering the entire back area. The extra room allows dogs to explore and lie down with less confinement, which can ease nerves during travel.

• Wide coverage reduces edge slipping and keeps dogs centered on the seat
• Suitable for large breeds and multi-dog households

Sturdy construction you can feel

Our design pairs a hard bottom board (3.7 lbs) with a robust multi-layer build that stays stable under shifting weight. It is tested to support up to 420 pounds, offering a reliable base for bigger dogs or active play.

• 7-layer material with 4x4-density Oxford fabric for durability
• Hard bottom board that folds to accommodate seating or safety seating if needed

Protection for your interior

Full back-seat coverage shields upholstery from hair, drool, scratches, and spills. Water resistance helps you wipe away messes, and the non-slip underside helps keep the cover in place while you drive.

• 100% waterproof layers protect seats and doors
• Non-slip base reduces shifting during driving

Smart details that make travel easier

A breathable mesh window helps your dog see you and stay calm, while reinforced webbing is designed for long-lasting use. Two large pockets keep toys and treats organized for the road.

• Mesh window improves airflow and interaction with your pet
• Two storage pockets for accessories and snacks

Fit and use

Designed for full-size crew cabs such as RAM 1500/2500/3500, Ford F-Series, GMC Sierra, Toyota Tundra, and Chevrolet Silverado. Easy to install and remove for quick cleanup between trips.
