Hi Morning Person,
Yes … it’s molded Dunlop but also has surface modifications.
They would work in a similar way to convoluted latex but with a slightly lesser effect (convoluted foam usually has more and deeper peaks and valleys). There is less material in the top part of the layer (making it softer) and then it would get firmer faster as you started sinking into the more solid part of the layer. There is more about how convoluted or surface modified layers work in post #2 here and post #2 here (in reply to question 4).
