The reason I'm asking is that, all of a sudden, I seem to have recumbutt all the time. I refoamed the seat at a local foam shop, ($12.00) and it hasn't improved the situation much. I bought a replacement stock seat base, and it's not that great either. My fear is that I may have to give it up altogether. But I love this bike and it really keeps the weight under control. So dropping the moolah may be in the picture. Online, it looks like $299-375.00, depending on which pad you get. If you have a cheaper source, I'd sure like to know. bk
