Take a good look at the wear on the driver’s armrest and the outboard driver’s seat; those are the most common wear spots for my M&M covers. On that note, I wore a hole completely in the drivers butt spot over the years; I don’t remember when I put these on but they have thousands of miles and many years of almost daily wear; if you were to rate them against your favorite denim jeans, I’d say they meet the mark all around. Keep in mind, I jump in with greasy arms and such which is not safe for any fabric and will break it down much faster.
I patched the driver’s seat with 3M adhesive and thick 1000 Cordura Canvas; I’m sure M&M would have repaired them but honestly a set of covers this old and so much use, patching was the best option. I’d save the repair cost from M&M and put them toward a brand new set of fronts; the cost, customer support, and life of the covers is beyond my expectations and wouldn’t look anywhere else for LR covers.
Notice the passenger seat, almost zero wear and likely 1/3 the use over the last few years.
No back seats so no covers.
Hope this helps.
