Hi Jmccar4919,
I can answer some of your questions in very general terms but you will need to contact Paramount for some of the more specific answers you may need.
Talalay latex is one of two methods used to make latex foam. It can use synthetic rubber or 100% natural rubber or a blend of both (which is the most common version of Talalay). There is more about the different types and blends of latex in post #6 here. The gel that is added to some types of latex is a phase change gel that can absorb and release heat within a certain temperature range to help regulate temperature. All the latex you are likely to encounter (either Dunlop or Talalay made with natural or synthetic rubber or a blend of both) will have been tested by Oeko-Tex or Eco-Institut for harmful substances and VOC’s (see post #2 here). The description says that they use 100% natural Talalay which would mean that there wasn’t any synthetic rubber in the blend although there would still be other substances used to make the latex in the compounding formula (see post #7 here). If the latex has gel added to it then it’s probably blended Talalay latex not 100% natural since I don’t believe that they make 100% natural Talalay with gel.
The description of the cover says that it uses 64% natural cotton but they don’t mention the other fibers in the blend although it would probably be polyester.
All they say about the wool is that it is New Zealand natural wool.
So called “soy based foam” is just polyfoam that has replaced a small percentage of one of the two main chemicals used to make the polyfoam (the polyol) with a polyol that is derived from soy oil (see post #2 here). It would be closely comparable in terms of durability to other types of polyfoam that are the same density range. I would want to know the density of any polyfoam in a mattress.
You would need to ask Paramount for information about the type of fire barrier they use and also for the specifics of all the layers and components in the mattress (see this article).
“Pure” is a very ambiguous term that doesn’t have any specific meaning when it comes to mattress materials (anything can be pure including synthetic chemicals if they aren’t mixed with other chemicals) but I’m guessing what you are really asking about is how “safe” are the materials.
If this is the case then these types of “safety” questions are a very complex subject with a lack of clear and definitive answers but there is 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 help answer “how safe is safe enough for me” that can help you decide on the types of materials you (or your son) are most comfortable having in your mattress. These types of issues are complex and are generally specific to each person and their individual sensitivities, circumstances, criteria, beliefs, and lifestyle choices.
