Recently bought a 2014 GTI.
Excellent condition, with only the very slightest, barely visible wear to the drivers side bolster.
Want to keep it this way, so searched high and low for a bolster protector/cover, with no joy. Seems there's really nothing out there for us, and I'm sure you all feel the same way I do, not wanting a full seat cover, which would ruin the look of those lovely tartan plaid seats.
Thought some may be interest to see the solution I managed to come up with. Could obviously be improved if you had them professionally stitched. My wife stitched these, and as a home made solution I reckon it's perfectly acceptable, and will certainly do the job of preventing the ugly bolster wear.
Costs peanuts to make, and if you use a material with a foam backing, it grips our cloth seats well and stays in place. At worst you could add a small piece of sticky backed velcro to each side.
Hope this helps some of you.
I see the camera flash has made it look a lot lighter than it is. It's actually a much closer match to the seat than the photo makes out.
