Query: Adjustment issues

Seat comfort is as individual as the cheeks that ride it, but I bought this seat with really high hopes, and when it was installed on my trek, I eaither felt like I was sliding off the front of it, or riding across the front "ridge". I tried raising or lowering it, and different tilt adjustments to no avail. To be fair, this may be more an issue of overall bike geometry, but I couldn't get it right.
