Like m48strat, I took out my back to back seats and replaced them with pedestals. I also had foam under the bases. What I did was take a saw and cut the foam out level with the frame that the seat bases were attatched to. Once they were out, I attached a 3/4 piece of plywood to the frame and then attatched the pedestal to it.<br /><br />Now to my problem. I bought a couple of pedestal seats from ebay that looked to be comfortable. However, when fishing for anytime at all, my bottom starts to ache as does my fishing partners. <br /><br />Since The boat is a beater but runs well and is perfect for fishing, I don't want to invest anymore than I have to. We're both pretty good sized guys so before I spend more for a piece of foam that may or may not help, I'd like to solicit ideas from the group. What kind of cushion would you use to put on top of the pedestal seat while your fishing or riding for a long time to make the seat more comfortable?
