Protection for everyday mess

Seat covers and floor hammocks use 4Knines’ K9-SHIELD® waterproof protective layer. Seams and zippers are not watertight, so check the exact model’s coverage.

A layout that works for you

Choose standard hammock coverage, a fitted bench cover or a split design. Rear fold-down and truck fold-up layouts use different products.

Clean it. Use it again.

Wipe-down or hose-down cleaning helps with everyday mess. Follow the care instructions for your exact cover, including drying directions in the guide below.

Measure first. Order with confidence.

Find the right 4Knines fit

Regular rear covers

54 inches wide

A starting point for many cars, midsize trucks and SUVs. Compare your actual bench measurements and headrest layout with the product diagram.

XL rear covers

60 inches wide

For wider rear benches, including many full-size trucks and SUVs. Measure the seat; a vehicle name alone does not guarantee fit.

Truck and door covers

Check your layout

Confirm fold-up seats and split direction for truck covers. Door guards require a separate door-panel measurement and window compatibility check.

Not sure which one to order? Send us your vehicle year, make and model, seat width, and whether the rear seats fold up or down. We’ll help you compare the options.

Good questions. Clear answers.

Do I need a standard hammock or a split hammock?

A standard rear hammock provides bench coverage with a hammock option. A split rear hammock adds access to all three seat belts and fold-down seats. Compare the exact product’s measurements and access points with your vehicle.

For standard hammock options, view the Regular rear hammock or XL rear hammock.

Which cover works with my truck’s rear seats folded up?

Choose a floor hammock for the floor area when crew-cab rear seats are folded up. Match the driver-side or passenger-side split to your truck. Floor hammocks do not protect the seating surface or door panels, and they are not compatible with the Ram Mega Cab.

Are these covers completely waterproof or chew-proof?

The seat covers and floor hammocks feature a waterproof protective bottom layer. Seams and zippers on rear-seat covers are not watertight. The covers are not chew-proof and are not recommended for aggressively destructive dogs.

Can I use heated or cooled seats, or tinted windows?

The rear-cover guides say not to use heated or cooled seat functions while the cover is installed. These 4Knines door guards are not recommended for tinted windows. Check the instructions for your exact product.

Where can I find the fit and installation guides?

Start with our fit help and manufacturer fit guide, then open the installation PDFs for your exact model. The PDF links let you view the manual or save a copy. Contact us if your model’s instructions are not listed.

Is a dog hammock a vehicle safety restraint?

No. A hammock or cover protects the interior; it is not a crash-tested dog restraint. Use an appropriate restraint or secured carrier according to its instructions. Never leave your dog unattended in a vehicle.

Who helps me if I have a question or need a return?
