Frequently asked questions

01 Which Size Is Best For My Vehicle?

We highly recommend measuring your cargo area to determine the best fit for your vehicle. Consider how you plan to use the liner. For example, if you plan to fold down two rows of seating and attach the headrest straps to driver and passenger seats, you may need the XL size to ensure adequate coverage.

Small Cargo Liner: 42” wide (including 6” side flaps) by 78” long (including 20” bumper flap). Best for compact SUVs (Honda HRV, Nissan Juke, Mini Clubman, Chevy Trax, Buick Encore). See dimensions diagram.

Large Cargo Liner: 52” wide (including 6” side flaps) by 82” long (including 20” bumper flap). Best for standard/mid-sized SUVs (Audi Q7*, BMW X5, Dodge Durango, Jeep Cherokee, Volkswagen Touareg, Porsche Cayenne, Ford Escape). See dimensions diagram.

XL Cargo Liner: 55” wide (including 6” side flaps) by 106” long (including 20” bumper flap). Best for large/oversized SUVs (Chevrolet Suburban/Tahoe, Ford Expedition, GMC Yukon, Land Rover Range Rover). See dimensions diagram.

For more information see our Fit Guide here.

02 Do I Need Adjustable Headrests To Secure The Cargo Liner?

Yes, the headrest straps were designed to be used with adjustable headrests. Some customers have used a carabiner clip or bungee cord to attach the straps, but this method is not recommended.

03 Are Cargo Liners Machine Washable? How Do I Clean The Cargo Liner?

For general everyday cleaning, we recommend vacuuming or using a moist cloth to clean the surface. For a more thorough cleaning, remove cargo liner from vehicle and hang over fence or clothesline, spray with a high pressure hose, and allow to air dry.

About machine washing: Cargo liners are machine washable on gentle cycle using cold water only and air dried. We recommend machine washing as little as possible to preserve the waterproof coating. Our cargo liners are very large and do not fit well in a home washing machine, so this is not the preferred method. Please avoid machines that have an agitator as this can damage the cover.

04 What Does The Lifetime Warranty Cover?

The 4Knines® Lifetime Warranty covers the product for the reasonable lifetime of the cargo cover as long as it has not been discontinued and was purchased directly from the owner of the 4Knines® brand. Proof of purchase or order number is required. The warranty covers manufacturing defects, defective hardware or materials (i.e. broken clips, headrest straps), irregular wear, or breakdown of the material. 4Knines® strives to provide superior customer service. If you have any problems with your product, please contact us and we will do whatever we can to make it right. (subject to change)

05 Is The Cargo Liner Available In A Variety Of Colors?

The Cargo Liner comes in Black, Grey, and Tan.

06 Is The Cargo Liner Waterproof?

Yes. Our liners are made with waterproof material. Small spills, snow, rain, and mud should be contained on the cover. However, the seams are not waterproof and liquid may seep through these areas.

07 Please Explain Your 100% Satisfaction Guarantee.

We stand behind our products 100%. If your 4Knines® product does not work for your vehicle for any reason, you may return it for a full refund within 30 days of purchase. No hassle. No explanation needed.

Awesome product!

Very easy to install. Only used once so far, but very high quality and seems like it will be great at protecting my seat!

Kinsey R. Verified buyer


I was weary about the products at first (I bought a backseat cover as well), but when they arrived they were fantastic quality. Looks classy, super easy to install, and my dog loves it. We live in the Sunshine State. The material is breathable, and doesn't get too heated. Definitely the best product out there. Luckily, Pinterest came through for me in discovering these amazing covers.

Split rear seat cover

Super easy to install. Hammock still allows us to see our dog easily. Drinking water and dribbles no problem. Just puddles up and does not penetrate. Website and communication top notch!!

Russell P. Verified buyer

Bed liner

My older dog put them to good use and the bedding stayed dry and just to wash covers. Great product and the dog line sleeping on the beds again. Plastic protected the bedding but but dog did not like the feeling.

Great Product

It stays pretty much in place and I have 2 German Shepherds that jump into the back of my SUV! It looks well made and I am very happy so far.

Kristen W. Verified buyer

Great Product

Everything fit perfectly, wish the sides can up further and could Velcro onto the side of the truck or suction onto the windows.
