This is a great product for protecting your backseat

Joseph SegarNovember 16, 2025

This comes in a nice carry bag, which is great if you want to put it away for occasional use! I love the larger padded panels for the bottom that give more support than most of them do. It fits my Jeep Trailhawk really well. I love that it has covers for the headrests, vented middle so the AC and still reach the back seat, and the door cover that attaches in the window gap so you dont have to hook it to the handles above the door and take it down every time. Muddy paws and fur are no match for this thing. Easy to clean, and the side flaps are a smart touch. Built for real use, not just looks. This does a great job protecting the leather with thick material. Highly recommended Read more

My backseat stays clean now - FINALLY

Kindle readerJanuary 13, 2026

I have a 70 lb lab mix who loves car rides but DESTROYS my interior. This cover solved that problem. The hard bottom is rigid and stable so my dog isnt sliding around on turns like he did with the soft hammock style covers I tried before. Door protectors slide into the window seal and stay put even when I crack the windows. Headrest covers catch the drool and mud that used to get all over my seats. Waterproof layer actually works because my dog jumped in soaking wet after a lake trip and nothing soaked through. Installation takes maybe 5 minutes and the straps hold it tight. Included leash attachment keeps him secure in the back. Best car accessory I've bought as a dog owner. Read more

25-lb Doberman + GMC Sierra = Perfect Fit!

JenjenNovember 5, 2025

This seat extender and hammock combo is an absolute game changer for anyone traveling with large dogs. It spans the entire backseat, giving my Doberman tons of secure space — no more slipping into the footwell during rides! The hard bottom supports up to 400 lbs and feels incredibly sturdy and stable under her paws. The waterproof fabric and door protectors are a lifesaver — muddy paws, rain, and spills don’t stand a chance. Installation was quick and easy, and it stays firmly in place even when my dog jumps in and out. Cleanup is just as simple: a quick hose-off and it’s good as new. If you’ve got a big truck or a big dog, this seat extender-hammock setup is a must-have for safe, comfortable, and mess-free road trips. Read more

So far, so good...

MCDecember 8, 2025

Seems of good quality...material and stitching feel pretty sturdy. It was easy enough to figure out the installation, however those metal tabs to hold the door panels in place didn't fit into my car's window openings. Not really sure how it can fit without interfering with the window operation. I'm going to cut that portion off both sides and secure everything with velcro. Also, decided to cut some extra copies of the boards they provide out of sturdy cardboard and slipped them into the pockets under the boards to reinforce the floor. I'd seen some complaints about these floors not being strong enough for heavy dogs. I added about a 1/4 inch of extra thickness using three cardboard sheets in each pocket, crisscrossing the corrugation. Strongly suggest this. Feels much more sturdy. May even pull the whole thing out and glue the cardboard sheets together into sandwiches for even more rigidity. I had a version w/o the hard floor previously. The only area my dogs could lay on was the seats. This version turns the entire area behind the front seats into usable space for them to lay down. They said they like it. If this thing lasts for 4 or 5 years, then it should get 5 stars. Read more

Can’t handle weight.

Jonathan PetersonNovember 24, 2025

I just received this item and set it up. Install was easy and it looks great but as soon as I put my 72lbs German Shepherd in the back the from left panel snapped. It lasted all of 10 minutes of him standing there. So much for the 420lbs weight limit. Read more

totally worth it for any pet owner!

Bryam c.November 5, 2025

I love this car seat cover! It fits perfectly in the back seat and completely protects my car from hair, dirt, and scratches. The waterproof material is strong and easy to clean; just wipe it down or shake it out. My dog feels super comfortable and safe while riding. It’s also easy to install and stays in place, even on long trips. Great quality and design. Read more

No heavy animals

Jenn BrownJanuary 2, 2026

Fit wise in my 2500 ram was fine. However the extender doesn’t hold the weight of my two dogs. Very unhappy Read more
