I bought a spare rider seat from cheap cycle parts. It was $38 iirc. I pulled the staples, carved out the hard foam and replaced it with some squishy eggcrate foam that came in a shipping box. It had the desired effect of lowering the seat but it expands back to make the seat look normal. The added benefit is the softer foam is more comfortable. I still have the stock seat if I need to return.
Corbin makes a high quality part but the foam they use is somewhere between concrete and pine for stiffness. They are known to break in at around 100,000 miles. And you could buy ten stock seats for the price.
