Solus, It is form fitting. The higher back side helps carry some of the pressure. For me with the reg seat I ended up with all my weight sitting on my butt bones. But it's probably not a big deal tripping cause I enjoy getting out to explore ever hour or so. I did get one for my pro boat when I was training for a race were the 1st portage was over 6 hours away and it was just right (for me). Half the prep for a race like that is getting super comfy.
