Tuzwa Dog Back Seat Extender – Hard Bottom Waterproof Car Seat Cover for Large Dogs

Give your dog more usable space in the back seat while helping protect your vehicle interior with the Tuzwa Dog Back Seat Extender, designed with a hard fiberboard bottom, up to 400 lb stated support, waterproof multilayer construction, scratch-resistant PU leather surface, breathable mesh window, foldable side design, and built-in storage pockets.

Measuring approximately 25 × 52 inches, this large dog car seat cover with hard bottom extends across the rear seating area and helps bridge the footwell, creating a broader, flatter platform for compatible dogs during road trips and everyday vehicle travel.

Hard Bottom Fiberboard Support

The Tuzwa hard bottom dog car seat cover uses a supportive fiberboard base designed to help prevent the platform from sagging into the rear footwell.

The supplied product information states support for up to 400 lb, providing a strong platform for compatible large dogs and multi-dog travel setups.

Waterproof Multilayer Construction

Protect your rear seating area from compatible spills, muddy paws, wet fur, and everyday pet messes.

The Tuzwa waterproof dog car seat cover uses multilayer construction with a TPU waterproof coating designed to help prevent liquids from passing through to the seat underneath during normal use.

Breathable Mesh Window

The integrated mesh viewing panel helps promote airflow between the front and rear portions of the vehicle.

It can also give your dog a clearer line of sight toward the front seating area during compatible travel.

This can make the Tuzwa dog car hammock feel less enclosed while maintaining separation between seating areas.

Foldable Side Design

Need room for both your dog and a passenger?

The foldable side configuration allows part of the cover to collapse or adjust so a compatible passenger can use part of the rear seat.

Suitable for Large Dogs

The supportive hard-bottom design and generous dimensions make this extender particularly suitable for compatible large dogs.

It can also be used in suitable multi-pet households when the combined load remains within the stated capacity and the dogs have adequate space.
