Cut foam with an electric knife. Foam cushions are available at most home decor stores and large department stores, but often these are expensive and not always the size or design style that you need.
Serrated blades are great for cutting thick foam. If you are cutting 3 inches thick or less try an Olfa L-2 utility knife. (Get the heavy duty blades for more dense material) These work great on spray foam, board type insulation, soft foam (for tool/pelican cases) etc. Good clean accurate cuts.
