It would be good to know what model of saddle. Some, like the prix de nations (I still have two of them that I still love) are VERY close contact and will do little to help you ride. That is what I like about them, but they are harder to ride in than some of the newer "puffier" saddles that have all kinds of knee/thigh blocks to hold you still and secure.
^^ I agree very much with Allison and tiny here. They are not the top saddles, but they are very decent (and usually run on cheap side used). But as Allison mentioned some models are quite hard under the butt and don't offer much of padding. But for $150 it's a very good deal.
