Replacement Helm Seat

[pk]

Greetings All! I am new to this site and looking for some advice. I bought a nice 1988 V20 about 2 years ago from a good guy in Ohio. The boat has a 205 Mercruiser and was set up for fishing/trolling. I have been pretty happy with the boat so far.
At this point I am trying to find a replacement helm seat. I can not figure out why they put such a tight seat in this boat. Any suggestions as for a good quality, reasonable $$ seat would be appreciated.
Thanks.
