Perfect seating position for me is right on the hump.

[yak]

I have long legs. I have read the forum suggestions 1) buy a replacement seat 2) remove the hump and cover the 2 holes. Is there a 3rd possibility. Could i "build up" the seat around the hump and sit on that? I bought a 5 inch thick foam (similar to a mattress-topper; it was made to cover with fabric and use as a chair bottom cushion). Could i cut out a hole the size of the hump and place the foam over the hump? I would have to cover it with some vinyl material and tuck it under the edges of the current seat. I am not worried about rain hitting the foam; i could cheaply replace it and it never rains here in Phoenix.
If i am successful, i will probably make $Millions£€. Of course, i would be willing to split the money with any forum members who are amateur inventors. Can you help me think of a better idea for building up the seat.
I was wondering if i would need to buy a Forza to get extra room but that seat only has 1 more inch (thanks to forum-member "kcpcx" for checking).

Buy an Air Hawk - they are made for that and would match black perfectly.
