Just did my seat last weekend before a 1000 mile trip. It was sagged out on the left side and the lumbar brace (3 inch curved piece) was broken on both sides. The previous owner also was a 'bigger' individual. I used self tapping screws to re-secure the lumbar brace and then added a soft piece of foam between it and the air bladders.
I then took a piece of panelling from the back of my old entertainment center and cut it to fit between the foam and spring wires. I then shimmed up the left side with pieces of carpet.
Re-installed and it is way firmer and much taller. A little to tall. I probably could have stopped at one piece of carpet in stead of three.
It was very comfortable to drive but did impair my vision a bit as I had to look 'under' the top of the window to see traffic lights.
Over all though I took a 200 K seat and made it feel like a new one.
As well, a friend of mine who is vertically challenged did raise his seat using spacers.
