I would want to try sitting in one sometime. Airlines might have a better time trying to push the idea if they can get mockups built that can be installed in terminals at major airlines. If it's actually not that bad, let people test it out. It looks terrible but so is sitting in a cramped airline chair with your knees jammed into the seatback. If the vertical seat at least gave the illusion of more room in the sense that you aren't physically pressed up against anything, it might feel more comfortable. Another issue with the vertical seats is that everyone is a different height and therefore a different inseam length, how do you accommodate shorter people and children while also fitting tall people in? Having the saddle/seat being able to move up and down like an office chair would help.
