Hi Connie,
Thanks for your kind words. I am glad that you found the information on our site helpful and assistive 
In fact we get many “Thank-yous” (on and off the site) and I appreciate your suggestions regarding having a topic of TMU Testimonials … .when we hit some rough patches with back end technicalities it is good to read a stream of “Thank You-s” to be reminded of the difference TMU can make … sometimes testimonials can be a bit of a “recipe” often played as a marketing tool and in mind with the educational nature of our site I’ve always trusted that those who have eyes to will see, but I’ll be toying with your idea of creating a “Thank-you” thread for a while.
I heartily agree with you that some “studies” like the one you mentioned capitalize on certain strengths of specific components or even the mattress as a whole but fail to mention any of the week links within a mattress which can be just as important (or even more) in one’s purchase decision. Choosing an appropriate mattress is as much a science as art as all layers, components, and features work together and each person’s body type and sleeping position are an important part of how each person interacts with a mattress. As you noticed there are many other interrelated variables as well and this is why I like to recommend that after doing a bit of research to understand your own needs and preferences getting in touch with a retailer/manufacturer that knows about mattress construction can save much time, energy, and frustration.
You can find the thoughts of many of our experts on temperature regulation such as the second paragraph in Post #2 here recently answered by Arizona Premium (Ken Hightower). There are also many aspects to sleeping cool and temperature regulation in a mattress and once again this will depend on how many different factors interact. There is more about this in post #2 here.
I look forward to learning about your progress finding a suitable mattress and to answering any questions you may have.
Phoenix
