Electric carving knife is a popular weapon of choice.

Thin bladed sharp carving knife. Get a helper to gentley pull the cut pieces apart to stop the blade binding. Take it slowly.

Electric carving knife.... but dont force it .. allow it to cut at its own pace

Another vote for the electric carving knife. Can't imagine why anyone would want such a thing for catering purposes, but they're great for foam. I bought one specially.

Luckily I never throw anything away, so I was able to find our electric knife in the loft where it had sat for 20 years. A straight edge below the foam makes it a simple job.

20 years before I bought mine, I was 9 and not very interested carving knives whether electric or manual

Not if all your edges are curved

Good point. An MDF template below the foam in that case, lined up with markings on the top.

And thanks for making me feel old, the knife was a wedding present.

I recently used my B&D scorpion saw with the metal cutting blade,6' memory foam was raised of the floor on 4' wood battens and had someone gently separating the foam as a cut, as someone said don't rush the cut, i found a pendulum action the same way a jigsaw cuts worked best, pushing the top of the balde into the foam then letting the bottom of the blade catch up and ended up with a perfect edge :encouragement:

A bandsaw with a fine blade is great for trimming to size and shape with easy accuracy

+1 for electric carving knife.

Spray the blade with silicon so that it slides smoothly but not if you intend glueing cut edges together.

Another good tip that I had forgotten.
