Hi gellibelly,
Unfortunately I don’t. I have tried to talk with them on many occasions to talk about there mattresses (and others have as well) but they have never returned my calls. while I like some of the things they are doing and they have better than average value (depending on the retail outlet that sells them) … they are not very responsive to consumer phone calls when the retailers don’t have answers to questions. They could do a lot better in this area.
The Peace comes in 3 firmness levels as you know and each has a comfort layer made up of 2" of latex along with various layers of softer polyfoam (they change these layers in each model to change the feel) and then they have a firmer polyfoam base layer (for support) as well. The middle polyfoam layers are partly for pressure relief (they work with the latex) and partly as a transition between the softer comfort layers and the firmer support layer. Eco-Flex is just polyfoam that has replaced a small percentage of the petrochemical polyols (one of the two main chemicals used to make polyfoam and memory foam) with a plant oil based substitute. It is basically another name for polyfoam but most manufacturers exaggerate how “green” this is to attract those who want more natural materials in their mattress and don’t realize that it is still primarily a petrochemical based foam. It’s called “greenwashing” :).
Because the specs aren’t available … perhaps the two most important things that you can use from this is that you like the feel of having some latex on top of your mattress and that an “in the middle” feel works well for you. Their “rating system” goes from one to ten and so does Dreamfoam so while they won’t be the same and the layering is different in each mattress … it can at least give you a rough guideline as to the firmness level you prefer.
4 way stretch cotton is a very good quality and breathable (temperature regulating) cover. It also puts you right on top of the latex so the latex feel comes through more. The quilting in the Dreamfoam would slightly reduce the feeling of the latex and make a slightly softer and less resilient surface feel (which some people actually prefer while some prefer the feel of being right on top of the latex).
Temperature regulation and ventilation in a mattress comes from a combination of several different components and layers including the breathability of the foam in the upper layers, the breathability of the quilting and ticking in the mattress (natural fibers are best here), the mattress protector, and the sheets and bedding. All of these work together to either enhance or reduce temperature regulation and allow for ventilation and humidity control. there is more about temperature regulation in post #2 here.
