Hi railit,
Welcome to the rabbit hole of chemical testing and “mattress safety issues” :dry:
To make matters even more confusing than the different standards (NIOSH, OSHA, EPA etc) … there are also different testing methods used for bedding materials that will make a big difference in the results (such as testing in a small chamber with 72 hour pre-conditioning vs testing the air quality in a room).
There’s a little more in post #2 here (which also has further links to other posts and resources) which may be of interest.
The majority of mattresses sold in the country don’t have any memory foam although if they don’t they will usually contain other types of foam such as polyfoam or latex and of course polyfoam also has some “issues” for many people depending on how each person answers the question “how safe is safe enough for me?”.
I would also be very careful with “organic” mattress claims because in many cases a mattress that is marketed as being organic only has an organic cover and “organic” is used in a marketing sense rather than indicating organic certification.
There are currently only three mattress manufacturers in the US that make any organic mattresses (GOTS certified not USDA certified) which are OMI, Naturepedic, and Savvy Rest and none of their organic mattresses contain any foam of any kind at all (they all make latex mattresses that aren’t certified organic).
Having said that there there are many manufacturers that use organic materials or latex in various layers of their mattress even though the mattress itself has no organic certification. Even latex needs other chemicals to make the foam so the GOLS organic certification for latex is only 95% organic and the other 5% is the other ingredients used to manufacture the foam.
In most cases … “organic” is more about mattress marketing than mattress fact. You can read a little more here about organic latex for example in post #6 here.
