Hard Bottom Back Seat Extender for Dogs

Transform your car's back seat into a spacious, comfortable platform for your dog. The hard bottom design provides real stability and support — no sagging, no sliding — making long car trips much more comfortable for large dogs, older dogs, or multi-dog families.

• Expands to 52" wide x 26" deep — full rear area coverage with room to walk and stretch
• Hard bottom supports up to 400 lbs — 3 built-in load-bearing plates, far sturdier than soft-bottom alternatives
• 7-layer waterproof construction — faux leather, quilted cotton, and 35D sponge; tested to not leak through to car seats
• Non-slip rubber bottom + adjustable straps — stays securely in place during the ride
• Foldable design — fold it up to seat a passenger or fit a child safety seat alongside
• Mesh window — improves airflow and lets you interact with your dog during the trip
• 2 large storage pockets — keep toys, treats, and travel essentials within reach
