I have a bad back and have had 3 ruptured discs over the years.
I find the Morgan very comfortable but I have changed the mount so that the seat can go further back and have raised it a little at the front for thigh support.
The 4 seater gives a better seating position as you are sitting higher with your legs lower.
The worst position for me is driving on a twist where pedals wheel and seat are at angles. BMW's are a nightmare with offset pedals.
