You mentioned you got one right around the time I did. I used mine for craft foam for boat bumpers. A marine grade craft foam has antifungal properties. Not sure who needs anti microbial properties more. A foam to sleep on or a foam exposed to a marine environment. I opted for no antimicrobial properties to sacrifice superior build for cost, But found it interesting they where pulling the non antimicrobial mattress toppers to replace them with antimicrobial copper doped.

Since the antimicrobial properties of silicon nitride is a relatively new scientific discovery I ponder it's various potential applications.

flexible polyurethane foams have been used as kitchen cleaners, body sponges, puffs, filter elements, and mattresses. (The '273 patent at col. 1, lines 11-13.) The background section also describes that these articles have been known to be impregnated with antibacterial agents. (The '273 patent at col. 1, lines 13-19.) According to the '273 patent, a problem with this existing approach is that the antibacterial foam does not retain its antibacterial action for an extended period of time, because the antibacterial agent soon escapes from the open cells.

You`d need to go through Crest's patent always. Unless using Silicon Nitride since there is no patent in place utilizing SiNi in foam. If a Navy ship has a mess hall. There's probably a kitchen sponge somewhere. That got there through a gov. contract btw.
