  • Durable and sturdy
Color: black Size: L
Great product, fits perfectly in my SUV. Easy installation and scratch resistant. I have a Belgian malinois who chews on the straps, scratches it, and easily cleanable material.

  • Good value, easy to use
Color: black Size: L
Fits well, and very adjustable for different vehicles. Seems well made and waterproof, but have only used a couple of times. Easy to set up and folds up out of the way. My only issue is that the buckles that go around the back headrests clip towards the inside, which is hard to reach for me (5'3") to reach in my CR-V. A taller person should have no trouble. ... show more

  • Great product.
Color: black Size: L
I’ve used one time. I unfortunately had my dog pass away before I was able to use it more. But for that one time this item was great! It helped him have balance (he was a senior dog) and didn’t wobble all over the place. Cleanup was easy. Just used a wet wipe. Protection level was 10/10. Easily folds up against the back of the front seats or folds flat in a square. It even has a little screen window behind the arm rest so your pup can see you better! Quality was great! Even came with a seatbelt! Comparing to other namebrand back seat extenders this is the best value. Would recommend over name brand products. ... show more

  • Good Overall, but My Puppy Chewed the Strap on Day One
Color: black Size: L
The PETICON back seat extender works really well and makes car rides much safer for my dog. The hard bottom is sturdy, fits perfectly across the back seat, and keeps my puppy from falling into the footwell. It’s comfortable and easy to clean, and installation was simple. The only issue I had is that my 5-month-old puppy managed to chew one of the straps on the very first day. The material of the extender itself is strong, but the strap wasn’t tough enough for a teething puppy. I still think the product is great, just make sure to keep the straps out of reach if you have a heavy chewer. Overall, it’s very useful and makes traveling with a dog much easier. ... show more

  • LOVE THIS!
Color: black Size: L
Very easy to put together and up. I bought different safety belts for it as I wanted something better. It came with 1 but I knew already what I wanted so I ordered different ones so what is pictured is not what it comes with (safety belts) however my dogs are able to lay out without falling off, it’s easier on their joints and bones! They absolutely love it and fall asleep so much better than without it as we drive ALOT and I take them whenever I am leaving for long drives. It has places to lock in through the seat and around headrests. It truly adds length to the seat, the quality is great. Worth the small investment! My dogs are comfy and secure and I’m a happy dog momma ! ... show more

  • Fits in my little car perfectly.
Color: black Size: L
Not only does it fit in my car, but my dog loves it. Easy to clean, excellent quality, easy to put in and it actually gives him more room because it has boards that go all the way to the back of the seats, giving him that space where he'd usually fall down behind the seats lol

  • Sturdy construction.
Color: gray Size: L
This works great for keeping my small dogs in the backseat while traveling or just going to the groomer. Very sturdy and doesn't give as the dogs walk on it. I would highly recommend even for large dogs.

  • WARNING: This Almost Lasted as Long as My Patience
Color: black Size: L
The media could not be loaded. I bought this backseat “extender” barrier and tether specifically for our 9-month-old, 50-pound, three-legged rescue puppy. She's sweet, not aggressive, she's just... determined and this product was no match. For the first couple of hours it seemed okay. She rested her face in the center gap, looking like the cutest thing ever. I relaxed, thinking we'd cracked the code for safe car travel, but then she decided she needed to join us up front for some quality time. The seat belt tether was the only thing holding her back, so she just chewed right through it in under a minute, clean snap, no hesitation, shoved the barrier down like it was tissue paper, stepping right over and voila! (did I mention she also was wearing TWO giant donuts around her neck! 😳) We were on a highway in the middle of nowhere with about 14 hours of driving left and this adorable tri-pawd puppy is now in the front seat, sprawled across the console, tail wagging like "Oh hey, this is my spot now." She's only 50 pounds, missing a front leg and wearing not one but TWO donuts around her neck.. I’m no expert, but this should not have been possible. The barrier itself is very flimsy and the tether/seat belt? Even worse! (apparently made of material tasting like freedom and snuggles to a determined puppy.) If your dog is a calm, perfect angel who never questions the rules, and doesn’t move, maybe? If your dog is even the slightest bit of anything else, do not waste your money, not worth the stress, safety risk or using your arm as a barrier for the remainder of a commute. Mia says 1 star for being boring. I say 1 star for almost giving us a heart attack.🐾🚗💨 ... show more
