I had a wide seat to begin with but it just wasn't thick or wide enough.. you guys know. I got this here Schwinn no-pressure super wide seat for this ebay seller for $23.00 and change including shipping- here's the link:

I would say it's a great seat, little to no vibration under 20MPH. My butt doesn't get numb or sore (shifting around alot on those long rides). It's kinda like I'm "perched" up on it (it's still super low on the frame). The only neg is that it's not really meant for serious peddling but ..I'm not doing alot of that.
What kind of seat or saddle do you have?
