I'm about 1-2 inches too short on the seat, and I think they said the seat was already one of the longer ones. I am not certain about that, I looked into getting a longer seat over 20 years ago in college and I could be remembering wrong. I know it's not the original seat, the original seat was a hard PITA, and I bought a softer padded and longer one as a teenager in high school that was more comfortable.
Sorry, I haven't used this bike in several years and I haven't looked into upgrading it in even longer. I was just wondering if it was a bad idea to use a bike too small just to go a mile each way to the train station so I don't put more wear & tear on the good bike if say we get unexpected rain (which happens frequently enough in the NW suburbs of Chicago to be an uncommon but not unheard of issue. Rain comes when there was no rain in the forecast in the morning paper.).
