Yes and no...the shell even on your couch and other furniture does make ignition and spread on the shell a little more difficult but once the underlying foam gets involved it's all over. When I was a FF and we did training burns a knife to the surface fabric made the day go a lot quicker. The old non-resistant stuff was rather fire resistant.
I don't think NFPA 13 A.5.6.3 classification changes. Are you calling it mattresses - foam (in finished form)? Seems to not apply because the finished form is not foam. There has, for a long time, been foam within mattresses so changes to CPSC wouldn't have changed anything. They were class III before the change and would still be today. Now at some point the foam is so thick but covered it's closer to furniture with foam cushioning and the jump to plastic design. So nothing has changed in sprinkler design and it's still a judgment call, good luck. Chris Cahill, P.E.

Is anyone familiar with this to be able to tell if this reduces the hazardous classification of the foam when stored in a retail store stockroom to 12' high? Stored on floor, flat, as if prepared for a princess and a pea. Owner would prefer not to take .2/1500 to .6 for obvious reasons, one being tenant fitout of a portion of an existing retail center.
