Car seats are all a problem as they need to raise the front of the squab to prevent you sliding under the belt in an accident, whereas the human body is most balanced when the knees are lower than the hips. So we sit in chairs designed for something other than health mostly. Like children at school who mostly sit on chairs which were designed with stackability as first priority!
I remember my MGB seats were so basic to look at but actually very comfortable as they were flat.
Having said all that I find the mog seats pretty good for my back....I put it down to the lack of suspension forcing the body core muscles to work properly
