So far my only approach to buying a seat is "That looks like a good one, I'll buy it and hope it works for me."
That isn't very cost effective... I don't think the bike store will let me return it after I ride around on it for a few hours. Which means if I don't like a seat that I bought, I'd have to buy yet another one just to try it out.
What are some good guidelines for selecting a new bike seat that doesn't feel like I've been sitting on a block of wood? How do you select one that "fits" when trial-and-error isn't an option?
I own a mountain bike and enjoy trail riding, but these days I ride on pavement most of the time.
