what about special order ibisafatso size for wastes 38-40, you could quite possible corner the market for big seats for fat people... I'm sure theres lots of fatsos like me that would LOVE a bucket seat that is just a little bit wider
I doubt you need more than +2 inches. You think your bones are more than 2 inches wider than mine, I dont think so, maybe the the 4 inches is 50% bone and the rest is jelly which will conform when seated.
