Hi heysan,
Based on the description it uses 100% natural latex (most likely Dunlop) which is a very high quality and durable material and there would certainly be no “weak links” in the mattress. Pirelli used to use Sapsa as their latex supplier (continuous pour Dunlop) but I believe that for the last few years they have been using molded Dunlop but I don’t know who currently supplies their latex.
I’m not familiar with the European market so I don’t know how it compares in terms of “value” to other similar mattresses but post #13 here has more about the most important parts of the “value” of a mattress purchase that can help you make more meaningful comparisons between mattresses.
