Is it sturdy enough for a large dog?

Yes. Internal hard boards keep the surface flat across the footwell instead of sagging like a fabric hammock. It is designed with medium and large dogs in mind. It is a comfort product, not a crash-safety device, so always use a crash-tested harness.

Will it fit my car, SUV or truck?

The extender measures 54 inches wide by 25.6 inches deep and attaches to adjustable headrests. It fits most sedans, SUVs, crossovers and pickup trucks. Please measure your back seat before ordering.

How hard is it to install?

No tools needed. Buckle the straps around the front and rear headrests, tuck in the seat anchors and zip up the side flaps. It takes just a few minutes.

How do I clean dog hair and mud?

The waterproof quilted top wipes clean with a damp cloth, and pet hair vacuums right off. Spot clean the cover when needed.

What if it doesn't work for me?

You can return it within 30 days of delivery. If it arrives damaged or incorrect, contact us within 7 days with photos and we will make it right at no cost.
