I have contacted the mfg regarding these flaws. As I can see in your photo, there is a area on the side of each seat that is not covered. I have two big dogs, a medium dog and a sometimes granddad. There is no reason for this uncovered area except design. Also, the seat covers slide around on the leather seats. On the side of each seat designed into my Honda CRA, there is a loop on each side. If the mfg had provide a strap to go thru this loop, the seat covers would not slide around.
Can't think of a better fix for rotting seat covers
My ride is nearly 13 years old and 200000 miles. Of course some things are not show room new...like the drivers seat covers. As everything else on it reflects my love for the Hokies, this seat cover was a no brainer. Just wish there were fasteners to reduce the lateral shifts.
