I believe, if I’m not mistaken, I’ve seen some posts by
@Jerry Bransford. Regarding some aftermarket seats he has been very happy with. Hopefully he will chime in and let you know the details of his set up.
I know a lot folks are very happy with bartract seat covers. They are expensive, but worth it according to countless reviews I’ve seen on them.
I personally find the stock seats in my 99 to be, probably the most comfortable seats of any vehicle I’ve ever owned. I’m thinking about some custom leather seat skins when it comes time. I’ve seen a website for some pretty affordable skins on here, but I can’t recall what it was.
