  • SAFETY & COMFORT FEATURES - 4Knines Crew Cab Cover provides access to all three seatbelts, child safety LATCH systems, and armrests. Unlike many other covers, 4Knines covers are FREE of AZO dyes and heavy metals like lead, arsenic, and mercury.
  • WATERPROOF & COLORFAST - Our new non-slip layer is a full continuous sheet of material to provide complete waterproofing of the seat bottom (seams, stitching, and zippers are not watertight). The non-slip backing and deep seat pockets ensure the cover stays in place. Our colorfast, high-temp rated materials will not damage your seat.
  • EASY TO INSTALL - Cover installs quickly with UV-protected adjustable headrest straps and quick-release clips. Check out Jim's installation video!

    Exclusive to 4Knines

    This is the only seat cover that allows you access to the middle seat belt, fold down seats or armrest without removing the cover. No other company has it (US Patent # 9,610,877 & 9,845,033 & 9,878,646).

    Frequently asked questions

    01 Will This Cover Fit My Crew Cab Truck?

    Fits Ford F-Series, Chevy Silverado, GMC Sierra, and Toyota Tundra crew cab trucks. This innovative cover allows you to use all the features of your crew cab's rear seat while keeping the cover in place.

    *This cover does NOT fit Nissan or Dodge Trucks, but we are working on a design that will be compatible. Stay Tuned!

    02 Are My Seat Belts Accessible?

    Yes! 4Knines® Rear Seat Covers have Velcro openings to allow access to all three seat belts.

    03 Will 4Knines® Crew Cab Cover Accommodate My Latch-Equipped Infant Car Seat?

    Yes! All 4Knines rear seat covers are LATCH compatible with Velcro openings for LATCH-equipped car seats.

    04 Do I Need Adjustable Headrests To Secure The Cover?

    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.

    05 Are 4Knines® Crew Cab Covers Machine Washable? How Do I Clean My Cover?

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

    About machine washing: 4Knines® Crew Cab Covers 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 seat covers 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.

    06 Is My 4Knines® Crew Cab Cover Colorfast? Will The Fabric Color Or Rubber Backing Transfer Onto My Leather Seats?

    Our covers are made with colorfast fabric and should not damage your leather. As a precaution, if the cover gets wet, consider removing it from the vehicle and allow to air dry. The non-slip backing was designed to withstand summer temperatures in Arizona and has a working temperature up to 140 degrees Fahrenheit. We do not recommend leaving the cover in your vehicle on extremely hot days as the temperature can easily rise above that in an enclosed car.

    07 Is 4Knines® Crew Cab Cover Available In A Variety Of Colors?

    The Crew Cab Cover is available in black, tan, and grey.

    08 Are 4Knines® Rear Seat Covers Waterproof?

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

    09 What Is Covered By The Lifetime Warranty?

    The 4Knines® Lifetime Warranty covers the product for life against manufacturing defects (materials and workmanship) when purchased through an authorized 4Knines dealer. Please refer to the 4Knines Warranty Page for complete details about our warranty.

    Proof of purchase or order number is required. 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)

    10 Please Explain The 4Knines® 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.

    Marcia C. Verified buyer

    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.
