If you would like to cut the foam to size yourself, there are various possibilities to cut the edges straight and clean.
Foam can be cut mechanically with a band saw with a fine-toothed or toothless blade.
Foam with a thickness of 20 mm - 30 mm can still be cut very well with sharp scissors. However, if you want to cut thicker foam, you will get very good results with an electric meat knife. Due to the two counter-rotating blades, the material is cut very precisely and cleanly. If you do not have an electric knife at hand, you can also use a conventional bread knife. The bread knife should have a serrated edge. Cutters or meat knives with a smooth blade are not recommended, because the knife becomes dull very quickly and you get frayed edges. a little vegetable oil on the recommended knife blade helps to simplify the cut.
Another possibility:
So that a "clean" cut is possible, it is advisable to treat the foam with some pressure (using a ruler) and compressit as much as possible to "0" and in this condition use a sharp
Cutter to cut through in one go.
