I have a mixture of seats in my rigs. My flatty has some aftermarket quadratech seats, and they kinda suck. They are new, and not worn in yet, so thats most of it.
My comp rig has suspension PRP's and I can wheel it all day, and they are super comfortable.
My crawler has the stock Toyota seats, and after a day of wheeling, I'm worn out. My DC Tacoma currently has stock seats (one of the ones I want to upgrade seats in). We put 1K+ miles on it in a weekend, almost every weekend during the summer, and I have started getting cramps in my knees due to the way I sit in the seats. I am looking at the reclining low bolster endurotrail PRP's. I don't really need the heat/cooled version, but I am getting old and fragile, so it has been a consideration.
I have 2 sets of their comp seats sitting in the garage, but the side bolsters for a small cab, DD rig don't work too well together.
:EDIT: was thinking Daily Drivers, but actually their reclining Enduro Trail. A slight bolster on the seat to keep you from sliding around, and same on the back. Just a little shape to keep you in place, but not so much that you can't get in and out of them.
