looking at a theropedic pure touch natural rest , latex mattress. 6" of dunlap hd foam core , with smf (24 ild) , and quilt flex cover.
is smf another way to call another type of foam?
Hi rpwjeep,
It probably means “surface modified foam” which can be done to any type of foam. One example of surface modifications are convoluted or “eggcrate” foam, and a few other examples are here and here and here.
