In looking at the front of the foam, I use my electric carving knife and cut the top and bottom edge off the front of the foam. Depending on the amount of curve, I cut anywhere from 1/4" to 1". There is no 'roundness' to the front face of the foam. It just has the top and bottom edges cut off.
I then add a layer of poly batting that wraps around the front curve. The cushion cover then creates a very smooth curve once the foam is inside the cushion cover.
Note: I do furniture upholstery, not boats. I would think the same technique would apply to boats, but others who know their fore from their aft may want to verify this.
