Foam packaging from a computer box. The foam is dense enough for structures, yet soft enough to easily cut with a razor knife.

At 4 feet long it runs the length of the table.

The openings are just big enough for a Ork Battle Wagon to fit, though not a Bane Blade. I wonder if that was intentional?
