Sharing as this may resonate with someone at some point. I seem to have two options. An aftermarket replacement seat or a custom shop replacement of the seat with softer foam. When speaking to my local pickup outfitters, they say they do the foam change quite often for the Tradesman-level trucks. I was quoted $700, but no way of testing for comfort. The second option is aftermarket. Scheel-Mann makes a Vario F Klima that is very adjustable and has good reviews. The manufacturer gave me two contacts in Texas where I could go and sit in one. The downside is that these cost many times that of the foam replacement. We use our pickup mainly to tow an RV, several thousand miles a year, so comfort is a real issue.
