Why the hard bottom matters

A hammock sags into the footwell. Your dog spends the drive bracing against it.

Hard bottom

A flat platform instead of a sagging sling.

Room to settle

Space to lie down and stay down.

Seat protection

Fur, mud and wet dog stay off the upholstery.

Quick install

Straps on and comes off in a minute.

Yes — the K9 Cruiser fits 95% of vehicles on the road, including trucks, SUVs, sedans, Jeeps, and minivans. From F-150s and Tacomas to Tellurides, 4Runners, Wranglers, and everything in between.

Pick Your Size

  • Check our quick Sizing Guide to choose between Regular and XL.
  • Regular fits most cars and mid-size SUVs. XL is built for full-size trucks and large SUVs. Both sizes comfortably support multiple dogs — the difference is the back seat dimensions of your vehicle.
  • Yes, it works with captain's chairs and bucket seats. The hard bottom spans the gap between seats so your dog has a flat, stable surface across the entire back row.

Still Not Sure?

Send us your make, model, and year — we'll tell you exactly which size fits best.

Free Exchanges & Returns

  • Got the wrong size? We'll exchange it for the right one — free.
  • Doesn't fit your vehicle at all? Send it back for a full refund, no questions asked.

A Quick Note On Side Panels

The side panels attach to your vehicle's rear grab handles for full door protection. No grab handles? No problem — we offer add-on Door Protection Panels that attach directly to your doors.

1. Quick Clean (After Every Trip)

  • Wipe down with a damp cloth to remove dirt, fur, and debris.
  • Muddy or wet? Hose it off outside — it rinses clean in seconds.

2. Deep Clean (When Needed)

  • Remove the hard-bottom inserts.
  • Machine wash the cover on gentle, cold water, mild detergent.
  • Skip bleach and fabric softener — both damage the waterproof coating.
  • Hang to air dry out of direct sunlight. Reinsert boards once dry.

3. Safety Check

  • Regularly check the straps, clips, and non-slip backing to ensure everything is secure for safe travel.

Take care of it, and it'll take care of your dog for years. If anything rips or tears, your warranty has you covered.

30-Day Risk-Free Guarantee

Take it on a road trip. Get it muddy. Let your dog test it out. If you or your pup don't love it for any reason, send it back within 30 days for a full refund — even if it's been used.

  • Wrong size? Free exchanges, no questions asked.
  • Doesn't fit your vehicle? Send it back for a full refund.
  • Just not what you expected? Same deal — money back, no hassle.

Rip & Tear Warranty

If your K9 Cruiser ever rips or tears under normal use with dogs under 300 lbs, we'll replace it free. Just contact us with your order number to confirm your warranty and we'll ship a new one out.

What's Covered:

  • Rips, tears, or seam failures from normal use

What's Not Covered:

  • Damage from chewing or biting
  • Wear from dogs over 300 lbs
  • Damage from non-dog use (hauling tools, freight, cargo, etc.)

Frequently Asked Questions

Got questions? We've got answers.

  • Yes — the K9 Cruiser is designed to fit virtually any car, truck, or SUV, including vehicles with captain chairs in the second row (Telluride, Palisade, Tahoe, Traverse, and more). Adjustable headrest and seat anchor straps lock it in place for a secure fit in any standard back seat.
  • Absolutely. The reinforced hard-bottom is built to support dogs of every size — from small terriers to 150-lb Ridgebacks, Cane Corsos, Bloodhounds, and Mastiffs. The rigid base prevents sagging, sliding, and the dreaded footwell drop that ruins soft hammock-style covers.
  • Most dog parents notice a calmer, more settled pup within the first ride or two. The flat, stable surface gives anxious and senior dogs something soft hammocks can't: a real, solid platform to lie down on. No more sliding on every turn, no more panicked panting — just a dog who actually wants to come along.
  • Very. The waterproof surface wipes clean in seconds with a damp cloth — mud, hair, drool, and accidents come right off without soaking through to your seats. For a deeper clean, the inserts pop out and the cover is machine-washable.
  • About 3 minutes the first time. Unfold the cover, click in the support boards, zip up the side panels, and hook the headrest and seat anchor straps. Once it's installed, you can leave it in permanently or fold it down in seconds whenever you need the back seat for passengers.
  • We offer a 30-day money-back guarantee on every K9 Cruiser. If it isn't perfect for you and your dog, send it back within 30 days for a full refund. No fine print, no restocking fees, no hassle.

I was very impressed with the design of the k9 cruiser. It was a perfect fit for my Genesis G80. The straps for securing the k9 cruiser were well thought out, and provided enough adjustment to make it just right.

Christopher M.

One trip, 2.5 hours each way and the dogs slept most of the trip. Even the younger dog that has always gone to the floor from the old hammock was relaxed and content.

Denise S.
Verified buyer

I love this seat cover. I feel better knowing that my dogs cannot seat surf, LOL. We just took a trip to KY and the dogs were comfortable and had plenty of room to move. Very well made and I love the shade of grey. I highly recommend this product!

John A.
Verified buyer

It was easy to install and very sturdy. A good product for the price. The dog seems much more comfortable having the extended floor space.

Ricky B.
Verified buyer

Our bandit loves it! He doesn't fall into the floor any more. And we love that he is safer now.

Jean S.
Verified buyer

My dogs loved all the extra room in the car. The seat cover kept my car clean of mud and fur. My husband now wants my car seat cover! Looks like we will be ordering one for his car also!

I found this on a social media network and thought I’d try the back seat carrier, and the steps. My German Shepherd is aging and getting in and out of my truck was hard for her. I ordered from your website and both products are amazing for her. She rides much better and is able to use the steps to get in, and out of the truck with NO issues. Great idea if your pet is aging and still loves to ride!!!

My fur baby loves this! I can tell she feels more comfortable, safe and secure when riding in the car. Great purchase.
