Ray, the driver's portion of the Corbin dual touring seat is 15" wide where you sit, 11" wide at the tank, 21" from the front of the seat up the butt curve to where the passenger seat starts and 15" from the front to where the seat starts to curve upwards behind your butt. It is scooped out somewhat for the driver and doesn't force me into the tank. Big improvement over the stock seat for both driver and passenger. My pillion hated the stock and gel passenger seats too, but loves the Corbin.
