Hi jaicovt,
I never mind doing some searching for the members here because I’m usually familiar with the search terms that will bring up the best options … and it also gives me a chance to add to any posts with any new outlets or further research I’ve done in the area.
Pure Latex Bliss are high quality all talalay latex mattresses with better than average value and their Natural line has known specs (which you can see in post #1 here). They can be helpful in providing some “latex guidance”. Gold Bond also tends to be more open about their specs and can be good value as well (depending on the outlet).
Even without local testing … most of the manufacturers that are members here and sell online … including Ken … do a very good job in helping their customers choose the layering that has the best odds of success but local testing can still be a helpful guideline that can help them help you more effectively. This depends on knowing the layering of any mattresses you are testing though and also realizing that they are usually only rough guidelines or “pointers” rather than mattresses that can be duplicated exactly because of differences in construction. They are all informative, helpful, and easy to work with on the phone.
