I'd suggest 8 cm, though it depends on how much strectch is in the fabric, also on the tension of the stitching, some covers can give a little more than others though thats something you should avoid testing.
If you wanted a better looking job use the 6 cm block with dacron wadding over the top, they will look less blocky that way.
You could of course use feathers or just dacron, my sofa has feather cushions and though it doesn't look neat its defintely comfortable, fritz Hansen uses a similar type of insert on the PK sofa, its looks great.
Best of luck.

different thickness
Hi BJ,
I am no specialist but you obtain a nice result if indeed you use a dense foam of lets say 7cm and then 1 or 2 layers of softer foam.Each time getting softer/lighter This gives a nice luxurious touch when sitting down. And indeed looks less 'blocky'.
ALso I think it is best you cover your foam layers with an extra layer of cotton to protect the from light (and therefor lasting longer)

batting
Batting also keeps the fabric from sticking to the foam and creating unsightly wrinkles when you get up. Be sure to get upholstery batting. Quilt batting is too soft and will pull apart eventually and end up getting all bunched.
I use a spray adhesive made for foam to stick the batting to the foam. It's messy but it works well.
