This project is very simple. I'm 1,84 mt tall and all the time I'm travelling around the word I have to stay a lot of hours seated so, for me, many time this is a big problem and I think it's also a problem for a lot of people. So the simple solution is: a slanted seat like the competition car seat in order to have the center of gravity of the weight on the bottom and not on the legs. Just some degrees (from 10 to 15), to be correctly evaluated, and we could stay seat in a manner super comfortable!! Just remember that is not the padding the solution of confortability but the slanting!! In this way it is possible to make a seat a lot more lighter with a big savings of money for the fuel.
