I too found it comfortable right out of the box. In fact, if I have a gripe with the saddle, it's that it softens up. But, I crank the bolt under the saddle a quarter of a turn and it's stiff again.
I read on the Internet that the sides can be stitched together to make it stiffer. I might give that a try.
Over all, I like that it's stiff and not padded, yet has the right amount of flex for absorbing the bumps. I can ride on it for hours, and have.
