Extending Office Chair?

I want to raise the height of my office chair, about 4" or so, but I don't know how to do it. The piston is already maxed and its still too short. Does anyone have any ideas on how I could accomplish this?

how does the base of the chair attach to the seat (and the back if they're connected differently)? could be as simple as simply removing the seat from the base and putting a piece of wood between them, then putting it all back together (with longer screws/bolts of course)
Hmmm, yes shimming it up like that would probably work with most chairs too
