if you are feeling like you are tipping forward you just need to remove a relatively small area of foam at the rear of the standard curve where you sit, use a pen to draw even marks on both sides and then use an electric carving knife if you have one (I bought a cheap one from argos a while ago and it works great), but my seat was done many years ago and I used a very sharp samurai sword to cut it, after shaping by cutting you can use a drum sander in a drill to smooth down the foam and do any fine adjustments to the shape, 'tip' don't use anything too aggressive to sand down the foam as it can grip and bite more out of the surface than you want (bad experiences), time gives better results,

I took the square edges off of mine as they gave me a burning sensation on long rides
