This back seat extender is a fantastic upgrade for anyone with a full-size truck and dogs. It fits perfectly in my 2013 Ford F150, and the metal insert that slides into the window seal is a clever feature—my door panel stays completely protected no matter what. The hard bottom design feels super sturdy and supports my big dog comfortably. It’s also waterproof and has great grip, so no slipping even during bumpy rides. Installation was easy, and cleaning is a breeze with just a quick wipe down. I started using it on the 9th day after buying, and after a couple of trips, it’s become an essential part of our travels. On our last ride, which was about 23 miles, my dog was calm and secure thanks to the included leash and mesh window design. If you’re a pet lover with a truck, this seat extender is an excellent investment for safe and comfortable travel. Highly recommend!

I’m really impressed with this back seat dog extender. It fits perfectly in my truck, the material feels premium and it’s truly waterproof. My dogs have more space, feel secure, and the mesh window is a great touch to reduce anxiety during rides. The hard base holds up well and it doesn’t slip, even with two big dogs. Installation took just minutes and cleaning it is a breeze. Totally worth the price!

I have a 90 lb German Shepherd who loves car rides, but trying to keep him comfortable (and safe) in the back seat of my Silverado was always a struggle...until now. This back seat extender is exactly what I needed. Installation was easy, it fits my truck perfectly, and I’m genuinely impressed with how sturdy the hard bottom is! It doesn’t sag at all, even when my dog shifts around. He now has a flat, stable surface to lay across the entire backseat, and I feel so much better knowing he’s not at risk of falling into the footwell anymore. The waterproof fabric and door protection flaps are the features I needed, no more muddy paw prints on the doors or seats after hikes. It’s held up great on several long drives already. If you travel with a big dog in a full-size truck, don’t hesitate. This is worth every penny.

This seat extender-hammock combo is a *game changer* for traveling with large dogs. It spans the backseat and gives my pup so much secure space (no more falling into the footwell during rides!) The hard bottom holds up to 400 lbs and feels sturdy and stable under my dog’s paws. I live for the waterproof fabric and door protection; muddy paws, rain, and spilled water don’t stand a chance. Installation was a breeze! It works perfectly with my F‑150,and it stays in place even when my dog jumps in and out. Cleanup’s super easy too; just hose it off and it’s good as new. Whether you’ve got a big truck or a big dog, this extender-hammock is a must-have for safe, comfortable, and mess-free road trips.

4 stars b/c we have to return, it doesn’t fit a 2025 F150 super crew if the back seats are pulled up so dogs can rom in open back seat area. Only fits if seats are in sitting position. Otherwise it’s made really well good quality material & only takes 20 seconds to set up. Wish they had one sized to fit with back seats flipped up.

This truck back seat extender has been amazing for my American Pit Terrier and Boston Terrier. It gives them plenty of space to stretch out and keeps them safe during rides. The hard bottom feels super sturdy—no sagging—and it easily holds their combined weight. I also love that it’s waterproof and has door protection, which helps keep my truck clean. Great quality and totally worth it!

I’ve used this back seat extender for 29 road trips with my Labrador so far, and it’s been a total game changer. I drive a 2020 Ford F-150 and the fit is absolutely spot on—way better than the universal ones I tried before. What really sets it apart is the solid hard bottom. It easily supports my 85-lb dog and feels super secure. The door protection feature is clever and actually stayed in place even when I rolled down the windows. The non-slip surface kept him steady during turns, and the mesh window calmed him down since he could still see me. It took me only 10 minutes to install the first time, and it’s been through 52 days of heavy use without any wear and tear. Cleaning it is simple—just a quick vacuum and wipe down. If you own a full-size truck and love traveling with your dog, this is a must-have. Solid build, smart design, and peace of mind all in one.
