Dunno, The Jeep has a nice form fit seat and I can tell you I got a few good kidney punches from being jostled around. If I got the seat in just the right spot so that I could brace my legs in the foot well, pushing my lower back into the lumbar with out too much reach to the dash mounted hand grab rail, and leaning forward a little so that the hits staid away from my upper back and head, I did okay.
The Unimogs are actually kind of funny. The tires and wheels are so big and the portal axles push everything up, so what looks like a big cab is really kind of short sitting above the frame. The seats are maybe only 8 inches above the floors, and the foot wells are straight forward and pushed out narrowly to the sides of the engine house. Seats didn't look, too bad though.
The Pinzguaers were a whole other story. They all had very military looking flat bottom and backed seats with very little cushion apparent. In the rear the benches faced each other, which didn't seem good for hardcore wheeling, BUT, no one looked to be flopping around, or complained of being uncomfortable. At least not that I heard. They had so much more ground clearance, bigger tires and big coil springs that they just seemed to pussy foot over the obstacles. A large boulder becomes a much smaller stone.
