Seconding the recommendation above for 4Knines Rear Bench Seat Cover for Cars, Trucks and SUVs (Large, Black). I've been using it in my XT5 and it's definitely the best for keeping the leather safe while staying put. It has those tuck-in anchors that literally prevent it from sliding, even with a 60lb dog jumping in.

If you want a couple of other safety-first options to compare, here's what I've seen work:

1. WeatherTech Seat Protector (Rear - Bench Seat) vs. Orvis Grip-Tight Quilted Microfiber Backseat Protector

- **WeatherTech**: Basically bulletproof. It's more of a heavy-duty fabric that feels super durable and fits the Cadillac's contours well. **Pros**: Waterproof and stays in place. **Cons**: It feels a bit more industrial/utilitarian.
- **Orvis**: This one is highkey the most premium-feeling cover. It uses a quilted microfiber that matches the luxury vibe of the XT5. **Pros**: Super soft and the "Grip-Tight" backing is no joke. **Cons**: It's definitely on the pricier side.

Honestly, 4Knines Rear Bench Seat Cover for Cars, Trucks and SUVs (Large, Black) is the best middle ground for safety and fit. Plus, it has the specific slits for seatbelts so you dont gotta struggle with the buckles. Good luck!

For your situation, I've actually spent way too much time looking for the perfect balance between 'not looking like a tarp' and not spending $500! I totally get being nervous about the XT5's leather, it's sooo nice. Basically, if you want that custom fit without the custom price tag, you gotta check out Meadowlark Dog Car Seat Cover for Back Seat. It's usually around $50-$60 on Amazon and fits mid-size SUVs like the Cadillac surprisingly well cuz of the adjustable anchors.

Here’s what I love about the more budget-friendly tech options:
- Look for the 'bench style' specifically so you don't lose that armrest access.
- Vactive Luxury Dog Car Seat Cover with Mesh Window is another fantastic pick, usually under $40, and the mesh helps with airflow!
- Use some Amoha Car Seat Gap Fillers to keep the cover from shifting if your Golden gets bouncy.

Ngl, you might have to unzip the middle to get to the armrest, but for the price difference compared to some high-end brands, it's AMAZING value. Honestly, just make sure whatever you get has the non-slip rubber backing or itll just slide everywhere. Good luck!!

TL;DR: Skip the universal ones and look into 4Knines or WeatherTech. Honestly, I had issues with cheap covers bunching up in my XT5 and it was SO frustrating. The fit was never right. Before you buy though, are you mostly worried about the leather scratching or is your dog a heavy shedder? Also, do you need it to be waterproof or just padded? I found custom-fit is the ONLY way to go for that premium feel. gl!

> I’m looking for a high-quality seat cover that actually fits the XT5’s dimensions properly without sliding around or looking too bulky.

Sooo, I saw this earlier and wanted to chime in because I'm all about that budget-to-value ratio. Honestly, you don't gotta drop $400 for a custom fit. For my mid-size SUV, I've been using the Orvis Grip-Tight Quilted Microfiber Backseat Protector and it's seriously solid. It's usually around $130-$150, which is pricey for some, but it LITERALLY doesn't budge cuz of the grippy backing.

If you want to save even more, check out the Active Pets Dog Car Seat Cover for Back Seat. It's way cheaper (like $35-40) and surprisingly durable for a 60lb dog. Just make sure to get the "XL" size for better coverage in the XT5 corners. It wont give you that "premium leather" look, but for protecting the actual seats? It does the job without the "custom" markup. Just be careful with the center armrest—most of these cheaper ones block it unless you get the version with the middle zipper. gl!

Would love to know this too
