Features

  • Expanded Backseat Space: Expanded to 52 x 24.5 inches, providing more space for dogs to play and preventing them from falling or sliding off the seat during sudden braking or parking. Suitable for large dogs, elderly dogs or multi-dog families.
  • Protect Backseat Space: Covers the entire backseat area, and the seats, bottoms, and sides of the doors are all protected. Keep the backseat clean and tidy, prevent scratches on the seats and door panels, and you don't have to worry about dog hair and claws.
  • Hard Bottom Provide Strong Support: Hard bottom car dog hammock is stronger and more stable than soft bottom dog hammock, and can hold up 400 pounds. The hard bottom uses a sturdy honeycomb board.
  • High-Quality Materials: Made of 7 layers of high-quality materials, outdoor-grade Oxford cloth with waterproof coating and anti-slip rubber on the bottom. So the product has good waterproof and anti-slip properties.
  • Mesh Window & Storage Pocket: The mesh window gives the dog a better view, better air circulation, and the dog can see you at any time to release the dog's anxiety. It is also convenient for you to check the dog's status.
  • Suitable for Most Vehicle & Easy to Clean: Perfect for cars, SUVs, and small trucks. No matter how dirty it is, it is very simple to clean. You can wipe it with a damp cloth, clean it with a vacuum cleaner, or rinse it with water. This is a perfect gift for dog lovers.

  • Great Back Seat Extender for Dogs
"This backseat extender for my dog is amazing! It gave my pup more space and kept him safe and comfortable during the ride. Great quality and super easy to install—highly recommend!"

  • Made multi-state travel easier
I used this to transport my two rabbits from Idaho to California. (Two days of travel.) It fit my 2019 Toyota Corolla perfectly. It was easy to assemble and disassemble. It is water resistant, so it kept my car safe from spills and food. Easy to clean. I forgot to take a picture of the whole set up, so enjoy this picture of a drugged up sleepy bunny. ... show more

  • Adjust the straps on the headrests to reduce the load put on the floor of the product
Perfect fit in the backseat of my Jeep. I have 4 dogs and the product supports the weight of all of them. Very happy with the quality. It wipes clean with a damp cloth.

  • Durable car seat cover
This has been the best addition to my mini van. Stays in place better than any other car cover I’ve used. Protects my seats better & is very durable.

  • Leather protector from dog nails
The quality of this cover was a surprise to me, it is the exact same product sold on other websites for over $169. So easy to install (if your car has headrests). The bottom is secure and I would by again for my other car if it had a backseat. Great value for the money. Add a dog seatbelt or stretch leash for safety. Easy to clean up, protects well from dog hair and scratched on leather interior. ... show more

  • Back seat extender for dogs
Nice, but can get annoying to put on and off.

  • Wish I had gotten this one earlier.
So far it works better and looks nicer than the one I spent $130 on! That one ripped apart at the seams. Easy to put together and install. I would recommend a padding or blanket on top when using. It is large enough for my three dogs which equal about 100 pounds altogether. Has saved my seats and helps keep the dogs from falling into the foot area and from coming upfront. ... show more

  • Waste of time/money! Looks nice but does not work.
FIRST the hard pieces are so small theres no point in having them. The straps need to be as tight as possible on the seats but dont function properly and they don't hold AT ALL. Pushed on it to test it and it ended up on the floor of my backseat so it doesn’t even work in the least and as far as it being a hard bottom seat extender it is NOT THAT. WILL be returning for a different kind as I feel it was misleading and a waste of my time and money on this. ... show more
