Hi traceym43,
There is a thread with some thoughts about the ironman mattresses here.
The Ironman site used to have more complete descriptions of their mattresses but the pages for each model have disappeared. If memory serves me correctly their top layers did include Celsion latex (a cooler version of Talalay) and other latex layers as well over different types of support systems.
While they certainly have an interesting construction … if you do go to Kelowna … the PLB and the Snugsleep would be much more typical of the feel of the two different types of latex.
the Ironman would be closer in its construction style (combination of memory foam and latex) to the Novotech.
