Reading LoveToCamp's reply gave me idea.

If the piece from the factory is really just too big, and that's the only problem, then I bet your carpenter friend could easily trim it down to the required size on a table saw. Like LTC said, it's foam in the center of it, which makes it lightweight, so it would be nice to be able to retain that feature. A solid piece of plywood will be much heavier.

One he trims it down, like LTC said, the foam will be exposed. Your friend could then simply cut a piece of veneer on his table saw, from some piece of wood that roughly resembles the grain pattern of the table. We're talking a piece of wood maybe 1/16-1/32" thick. Then simply glue that veneer onto the edge of the just-trimmed table with the exposed foam.

Either way would work fine.....
