Stevie:
Here's a photo of a seat that I installed on my boat:

It's very comfortable and has a lot of storage underneath. I installed a third tank (18 gals) there, and it still has room for spare oil, life preservers, rod holders, etc.
I bought the seat from West Marine:

I cut down the aluminum supports somewhat so that the back would sit flush with the base.
V20s are great all-around boats. Hope you enjoy yours.
