Hi Lisa_Mocha,
I would treat Dunlop and Talalay as being roughly equivalent in terms of motion isolation. Latex is very “point elastic” which means that it compresses in a local area under compression without affecting the area around it. Both are “good” although of course memory foam is the leader in this category because it not only compresses locally but also absorbs energy while latex is much more resilient and “returns” the energy which is why it’s more “springy”.
There is more about motion isolation and vibration “damping” in post #4 here.
