Do I still need a harness with this?

Yes. This protects the car and helps your dog settle, but a dog should also be restrained with a crash-tested harness and tether, or a crate/dog guard, per Highway Code Rule 57.

How does it fit - will it mark my car?

It anchors to the head-rest posts and/or the seat-belt buckle with straps and clips. No adhesive, screws or permanent fixings, and nothing that marks the trim.

See the spec table - covers and hammocks machine-wash at 30°C, liners wipe or hose off. Don't tumble-dry waterproof backing.
