Hi zkimmer,
It’s uncommon to find 100% natural molded Dunlop in softer versions than @ 20 ILD or @ 70 kg/m3 (both ILD and density are never exact). Most of the latex that is softer than this would usually be either softer Talalay (either blended or 100% natural) or continuous pour Dunlop latex. There is more about the different types and blends of latex in post #6 here.
I’m looking forward to seeing how things are progressing in another week or two and of course what you end up deciding after that.
Where did you buy your mattress?
