I too wanted to replace our thin plastic seat and I needed more room as well. I didn't think the elongated seat would do well on a round bowl. I bought one of the "slow close" seats, got out the old jig saw, file and sandpaper and "elongated" the frontal area to achieve the issue of more room. Works like a charm. One Problem, well actually two. I often go to a friends house to visit and have been used to just dropping the lid. WHAM! down comes the standard toilet seat & lid. Our friend is now wondering "what was that?". Problem two! Your average home toilet has no pedal. How many times have ya'll went for the pedal and it isn't there???
