HNCPSY Hard-Bottom Dog Car Seat Cover with Back Seat Extender, 68 x 52 in, Waterproof

HNCPSY is a hard-bottom dog car seat cover and back-seat extender designed to give dogs a more supportive travel area, with a three-panel honeycomb board that supports over 400 lb.

• Three honeycomb panels and a hard bottom — create a firm platform for dogs riding in the back seat.
• Provides an extra 50% of space — gives dogs more room to settle during car trips.
• Double waterproof fabric layers — help shield vehicle upholstery from water and stains.
• Full-door protectors — help keep doors clear of fur, dirt, stains and drool.
• 600D heavy-duty fabric, soft cotton and non-slip fabric — combine a cushioned surface with a grip-focused underside.

Dogs can bring fur, muddy paws and moisture into a vehicle, while a standard back seat may leave limited room to rest. This cover is made for car journeys with dogs, including trips when a dog leans toward an open window or rests its paws against the door. It also creates an extended back-seat area rather than covering only the seat surface.

How does the hard-bottom extender help dogs ride?

The board’s three honeycomb panels form a firm, extended platform across the back-seat area. Its stated support capacity is over 400 lb, and the added space is designed to accommodate one large dog or multiple smaller dogs. The non-slip dot rubber on the bottom helps keep the cover from shifting and reduces slipping for a dog on the surface.

• Hard-bottom construction extends the usable resting area.
• Non-slip dot rubber underside helps limit movement.

Will this cover fit my vehicle’s back seat?

The cover measures 68 x 52 in (173 x 132 cm) and is suitable for most cars, SUVs, and small- to medium-sized trucks. Compare those dimensions with your back-seat area when choosing a cover. The door protectors are designed to cover the entire door, adding coverage beyond the seating surface.

• Made for back seats in most cars, SUVs, and small- or medium-sized trucks.
• Includes coverage for the vehicle’s door area.

What materials help protect the seats and doors?

The cover combines 600D heavy-duty fabric, soft cotton, a stable board, and non-slip fabric. Its double waterproof layer helps prevent water and stains from penetrating the car seat, while the scratch-resistant design helps guard upholstery from pet claws. The cover also helps contain hair, dirt, stains, and urine during everyday travel.

• Waterproof fabric helps protect against moisture and spills.
• Scratch-resistant construction helps shield upholstery from scratches.
• Door coverage helps protect against paws, fur, and drool.

HNCPSY suits dog owners who want an extended, firm travel surface and coverage for both the back seat and doors. Its dimensions are intended for most cars, SUVs, and small- to medium-sized trucks, making it a practical fit for shared road trips with pets.
