ROUWINNE Back Seat Extender for Dogs – 59 Inches Wide, 400 lb Capacity, Waterproof Dog Hammock for Crew Cab Trucks

Maximize Your Back Seat, Elevate Pet Comfort

The ROUWINNE back seat extender for dogs is designed to transform the rear cabin into a spacious, secure zone for your pet. When extended to 59 inches in width and 28.74 inches in depth, it delivers full coverage of the rear area, so dogs can stretch out without crowding the front seats. This setup is ideal for daily errands and longer trips alike, helping dogs settle in with a defined, comfortable space. It’s built with versatility in mind for full-size crew cabs, including RAM 1500, RAM 2500/3500, Ford F-150/F-250/F-350, GMC Sierra 1500/2500/3500, Toyota Tundra, and Chevrolet Silverado models.

Sturdy, Safe, and Ready for Big Pups

A hard bottom distinguishes this extender from softer options. It can support up to 400 pounds, offering stable footing for large dogs, senior pets, or a multi-dog household. The 3.7-pound board folds neatly to leave room for a passenger seat or child safety seat when needed, providing flexible use for families on the go.

• 59 inches wide and 28.74 inches deep for full rear coverage
• Rigid bottom supports up to 400 pounds
• 3.7 lb board folds to accommodate a seat or a child seat

Protection, Cleanliness, and Easy Care

Seven-layer materials—including a PU coating and a TPU waterproof layer—provide robust protection against moisture, hair, slobber, and claws. The back seat remains tidier, and it’s easier to place items in the original foot space area. A non-slip bottom keeps the extender in place, so you can focus on the road rather than adjusting the setup.

• 100% waterproof, shielding back seats and doors
• Locks in place with a non-slip rubber bottom for security
• Simple to wipe clean for quick maintenance
• Protects upholstery from scratches and everyday messes

Comfort, Interaction, and Convenience on the Road

A breathable mesh window improves airflow and lets dogs see you, which can help reduce anxiety during drives. The mesh window features non-slip zippers on both sides for easy interaction. Encrypted, wider webbing latches add extra sturdiness, while two large pockets hold toys and snacks—keeping essentials within arm’s reach for a calmer journey.

• Mesh window enhances airflow and dog interaction
• Non-slip zippers and sturdy webbing latch for added security
• Two large pockets for toys, treats, and leashes
• Easy setup and cleanup for busy households

Designed for drivers who want practical, real-world benefits without promising guarantees. If your vehicle is a typical full-size crew cab, this extender aims to offer a larger, cleaner, and more comfortable space for your canine companions.
