Turn the back seat into a proper travel bed. This heavy-duty dog car seat cover uses a rigid hard-bottom platform to bridge the footwells, creating one flat, level surface so your dog can lie down and settle instead of bracing on every corner. Built from scratch-resistant 600D waterproof fabric with quilted padding and a non-slip backing, it shields upholstery from mud, claws, drool and hair, then folds away when you need the seats back. Rated to hold large breeds, and fits the majority of cars, estates and SUVs. Free UK delivery.

One flat bed, no gaps

Your seats, untouched

Quilted waterproof 600D fabric catches hair, mud and the odd wet dog, then wipes or shakes clean. The seats underneath stay showroom fresh.

Frequently Asked Questions

Will it fit my car?

It fits the back seats of almost all hatchbacks, saloons and SUVs. The straps loop around the headrests and adjust to size, and the platform sits across standard seat widths.

What makes the hard bottom better than a normal hammock?

A fabric hammock sags and swings with every corner. The rigid platform gives dogs a stable, flat floor, which visibly reduces travel anxiety and sliding.

Is it really waterproof?

Yes, the 600D layered fabric stops water, mud and hair reaching the seats. Rain-soaked dogs and beach trips are exactly what it is made for.

How do I clean it after a muddy walk?

Shake it out, wipe it down with a damp cloth, and it is ready to go again. For a deeper clean the fabric can be hosed off and air dried.

Can I still use a seat belt with it?

Yes, the design keeps the belt buckles accessible, so you can clip a dog harness restraint through as normal for safe, legal travel.
