Hi L-overwhelmed,
[quote]When you say:
It would certainly be suitable for a child both in terms of firmness and durability and any type or blend of latex would also be “safe enough” for children as well.
…what part of the bed would make the rating safe enough and not safe?[/quote]
From my previous reply …
If a mattress included a layer or component that didn’t have a reliable safety certification then its safety would be much more difficult to assess and more uncertain.
While it may be more information than you are looking for or really want or need to know … there is also a lot more information in post #2 here and the more detailed posts and information it links to about safe, natural, organic, “chemical free”, and “green” mattresses and mattress materials that can help you sort through some of the marketing information and terminology that you will encounter in the industry and can help you differentiate between them and answer “how safe is safe enough for me” and that can help you decide on the type of materials and components you are most comfortable having in your mattress or on the certifications that may be important to you. These types of issues are complex and are generally specific to each person and their individual sensitivities, circumstances, criteria, beliefs, and lifestyle choices.
I would use the firmness guidelines in post #2 here that I linked in my last reply… I would avoid soft mattresses for children (although I would consider 28 ILD to be medium)
My comments in post #2 here should be helpful. 28 ILD is in a medium firmness range although it would be considered to be relatively “soft” when it’s used as a support core.
