Have you gone into an LBS & had one "fitted"? That's always seemed a little embarrassing to me, but they have ways of measuring your sit bones. If you have that, then it's easier to get the right saddle. Also, many LBSs have programs that allow you to continue "trading in" the saddle that you just bought from them until you get the right one. Believe me, I'm all about saving a buck, but this is a case where supporting your LBS (if they're good) is totally worth it IMO.
I second getting your SIT bones measured. This measurement will give you an idea of how wide of a saddle you should be on. The guideline is to add 10-20 mm to center to center measurement and that would be your saddle width. Set up of the bike also makes a huge difference in how a saddle will feel. A saddle too high will have you reaching on every pedal stroke and your hips will rock back and forth, cause uncomfortable pressure on soft tissues. The tilt of the saddle and you pelvic mobility also plays a role. Start with the saddle level and make small adjustments. Hope that helps. Find a good shop that has a saddle demo program.
had my sitting bone measured as well but you can do it at home, just sit on neoprene or similar and measure the distance between the most prominent indents.
However, I have a specialised womens ariel as well as it is incredible comfy and has lasted me two years give or take and its only just now starting to go on the stitches, Im considering replacing it now but am tore between the comfort of the specialised or the cheapness and less obvious looking saddle..
There's a seat for every behind. Erm, or something like that. A good saddle fitting or demo program is a good bet, as others suggested.
My wife has a curvy behind, too. I took the shotgun approach for her. I borrowed or bought a few saddles and let her choose after putting some miles on each. She settled on the Charge Ladle (Ladies version of the uber-awesome Charge Spoon).
Finding the right seat is tough and expensive. I went through a lot of trial and errors. I use Terry's Butterfly. Love it! I have three now. One is pretty much dead from heavy use. I commute as well as mountain bike year round. I have a big arse and it fits great.
