Hi JacqCud,
All latex is “processed” to some degree (you couldn’t sleep on the liquid field latex that comes from a tree or liquid synthetic latex) and is manufactured with either the Dunlop process (or a variant such as continuous pour Dunlop) or the Talalay process using either natural rubber, synthetic rubber, or a blend of both.
There is more about the different types and blends of latex in post #6 here.
The latex in the mattress you are considering could be made from 100 % natural rubber 9which means that there is no synthetic rubber in the compounding formula) but even if it’s 100% natural there will still be other substances in the formula that are used to manufacturer the latex (see post #7 here).
[quote]For just the mattress it is 3699 or 3899 for the set (mattress and box spring).
We are hoping to get to TO tomorrow to check out Dormio.[/quote]
I would want to know the type and blend of the latex so you can make more “apples to apples” comparisons with other mattresses but any type of latex will be a durable material. The latex that is used in mattresses also won’t have fire retardant chemicals in the formula or sprayed on the latex.
As I mentioned I would make some careful “value” comparisons because the mattress you are looking at is in a fairly high budget range compared to other mattresses that would also be using 9" of the same type and blend of latex with a similar design.
