Wow, this product is awesome!! I'm so glad I found it and took a chance ordering it. I have a 2026 Escalade with captain's seats and a 95lb dog, the XL size is perfect. It was super easy to install the first time, and now is very easy to use when needed. I love that the door flaps open with the doors, unlike other versions where the sides must be zipped. The floor of this is very sturdy and doesn't buckle at all under the weight of my large dog without anything under it to support it between the two chairs. It is super spacious so my dog loves it. And I love that there is a zippered mesh flap in the middle front so we can keep it up or down. It comes with a carrying case and is very easy to fold up and store it in there. Really great product!!

After much research, I decided to go with the wisdom of "You get what you pay for." True, the Ruff Liners Standard Back Seat Extender costs more. AND IT'S WORTH EVERY PENNY. Everything about this Ruff Liners is well-made and sturdy. It's easy to install. The window guards stay in place! The standard size fits just about perfectly in my 2024 Subaru Crosstrek. If you can spend the extra for Ruff Liners, do it. Your pup and your vehicle are worth it!

I put this in the back seat of a 2025 Tundra. It fits great. I have confidence that I'll remain happy, despite only one use so far. I love the fact that my doors are now protected and I can open the door and let the dog out without unzipping a panel. The door panels attach via little pieces that fit into the gap by the windows and was concerned the window tint might get scratched up from the window going up & down: no negative results yet. Packs up eask and i keep it in the bed of my truck under the tonneau. Highly recommend. It's the reason to pay the extra money.
