There are "massager" seats available.... How they work is to vary the air pressure in multiple bags by turning on one switch, the seat I had had 5 or 6 different bags in it from lower lumbar all the way up the seat back.... It also had 2 or 3 adjustments, not automatic, on the seat pad as well... I wasn't a fan of that particular function of that seat, but I found comfort in my normal adjustments so it wasn't needed for me.
