A decent upholsterer could construct a foam cushion that could be made up totally to your liking. Harder on the edges, softer in the middle. Even progressive densities could be made. Initial softness with a firmer base. Or whatever combo that suits you.
Pretty typical project for custom Hot Rod seating.
If just the seat was brought to my shop, (No truck!) I'd do a job like that for the same price as a generic cushion.
