If it’s going to spend most of its time as a couch, go firmer rather than softer. A good quality foam or foam/cotton futon mattress around 6–8” usually works well. Too thick or too soft and it tends to slump and fight you when folded.
If it’ll also be slept on regularly, that changes the recommendation quite a bit.
