Hi ShopperGirl,
There are a few memory foams that are Oeko-Tex certified but you will generally only find them in a "finished mattress (see here for example) and not as individual layers that can be purchased individually.
I’m not certain where you read this but it certainly wasn’t on this forum (and this is the only place that I post).
They do use high quality materials in their mattresses … but I generally suggest that anyone that is considering them make some very careful value comparisons with other similar mattresses that are in lower budget ranges.
While I do recommend the members here “as a group” (and Savvy Rest isn’t one of the members here) because I believe that they compete well with the best in the industry in terms of their quality, value, service, knowledge, and transparency … I don’t make specific suggestions or recommendations for either a mattress, manufacturers/retailers, or combinations of materials or components because the first “rule” of mattress shopping is to always remember that you are the only one that can feel what you feel on a mattress and there are too many unknowns, variables, and personal preferences involved that are unique to each person to use a formula or for anyone to be able to predict or make a specific suggestion or recommendation about which mattress or combination of materials and components or which type of mattress would be the best “match” for you in terms of “comfort” or PPP or how a mattress will “feel” to you or compare to another mattress based on specs (either yours or a mattress) or “theory at a distance” that can possibly be more accurate than your own careful testing (hopefully using the testing guidelines in step 4 of the tutorial) or your own personal sleeping experience (see mattress firmness/comfort levels in post #2 here).
I also don’t believe that most mattress materials are “toxic” and I think that much if not most of the information about “toxic” materials on the internet is very misleading and in many cases is more about marketing than anything else.
For example … one of the most common replies in the forum for those that are getting overly “caught up” in these types of issues is this one …
I believe that the Marriott (Jamison) mattresses use 1.8 lb polyfoam which as you can see in the quality/durability guidelines here (and unlike the materials used in many other hotel mattresses) is a good quality material.
