I had plenty of experience with air seats when I drove fire trucks for a living, because of horrible city streets here they were a great help, but you are correct it was a lot of bouncing. Thank goodness our runs were usually short drives!
When I get back from my upcoming New England trip I may try to get a Flexsteel model number off the seat and see if they (Flexsteel) possibly offer a stiffer lower cushion. For me anyway, that would be a good start.
