Looking for short bed mattress suggestions

Hello all! I built a platform and am trying to find a rollup or folding type mattress to fit the short bed. I plan to sleep diagonally and keep tailgate closed. Full mattresses are too long and I am not a fan of air mattresses. One idea I had was to cut memory foam to size (58" x 60"), but laid on a 3in and not enough support. Doubling to 6in would be a lot of damn memory foam and be unruly as far as accessing the doors I put in the back half.

Any suggestions? Thanks!!

Hi! Was wondering if you ever found a solution for this, I am trying to do the same thing

 

I built a real simple platform with 8" boards and cheap plywood. It does the trick, but leaves minimal room for headspace. Works for now, but may modify next year.
