[Merv and Sharon]

Just try different pieces of wood under the front of the seat, with her in the seat. When her eyes are in the middle of the screen that s/could be it! She might like lower, however? You could make two brackets that were higher at one end than the other for each side to bolt on to the rails (length-wise). That would produce a slope from front to rear - u could re-bolt the seat at different points, as she preferred. This would probably be the same extra height as a slider tho'.
