We put together this sizing guide to help answer some frequently asked questions. We hope it helps! – Jim and Maggie


We love traveling with our dogs. After all, they are part of the family. But much like our twin daughters, our two Dobermans are rambunctious and sometimes manage to get themselves into some nasty messes. Like you, we don’t want our dogs to destroy our vehicle's interior, so we developed a collection of luxurious “Life-Proof” products to protect our cars from muddy paw prints, claw marks, dog fur, drooling, and the dreaded “accident.”

Your vehicle’s cargo area likely takes a lot of abuse! Especially, if your furry passengers jump in to accompany you on errands and adventures. Protect your interior with a durable 4Knines cargo liner. We think you will prefer it to the old blanket or the “disposable” cargo liner you have been using! In fact, we guarantee it!


  • Sizing - Deciding on the best size cargo liner can be a little tricky. We are here to help!
    First, consider how you plan to use the cover. Will you attach to the front headrests or to the back headrests? Do you plan to lower one or both rear seats?
    Next, measure the length and width of area you want to cover - be sure to measure from the headrest, down the back of the seat, all the way past the bumper.
    Then, make the best decision you can based on the following information and place your order.
    Finally...if it ends up being the wrong size, don’t worry! We will be happy to help you with an exchange.
    Small (42” x 78” including 20” bumper guard) - small/compact SUVs
    Large (52” x 82” including 20” bumper guard) - standard SUVs
    Extra Large (55” x 106” including 20” bumper guard) - full-size SUVs
    Check out our sizing guide for additional guidance and recommendations

Front Bucket Seat Covers

Love, love love our front seat covers. Now Miss Maxie can ride in either of our vehicles. It’s a win win for all 3 of us ????????

Sharon Tieman

Puppy misadventure

My 8 month old lab puppy ate something and it required a trip to the vet. They administered peroxide to induce vomiting. He seemed unaffected by the entire experience and after waiting 45 minutes with no results, we were sent home. Naturally, he threw up in the car on the way home. I had recently bought the split rear seat cover. It saved the back seat of my car and cleaned up beautifully. I can only imagine how the cloth seat would have absorbed the odor and stain without the protection of the seat cover. Buying your seat cover was the smartest decision I've made. Love the hammock option.

Christine Cooley

XL rear seat hammock cover

I own a 2015 Toyota Tundra CrewMax. I was concerned that the XL seat cover wouldn't be big enough for our pups. However, after installing it easily, our pups took to it immediately! Ellie loved the hammock part that comes off the seat a little and slept in it on one of our most recent road trips.

JP Nelson

Perfect Fit!

We had fallen back to just putting a sheet over our seats as our Bernese Mountain Dog and our cars never found a perfect match with any of the seat covers we tried until this front seat cover. We immediately put in an order for the backseat cover from 4Knines to give our BMD more room.

Erin Allen

Service dog approved

Dave Clark

Perfect seat cover- just what I was looking for

I ordered the Split Rear Back Seat Cover - Grey Regular Fitted - Non Hammock option for my 1999 Ford F-150 pickup truck. It fits perfectly in the front seat. Easy to take off and on and looks beautiful.
