Which is better?
Dunlop is denser, which makes it a bit firmer overall than Talalay. Talalay is a good choice if you'd like a pillowy-soft surface "feel". What matters is which type, or which combination, will create the right comfort and support for your needs. Both make a fine mattress and are extremely pure in comparison to conventional mattress materials.
Although Talalay has a wider range of ILDs, or firmness grades, Dunlop is generally heavier. If you like a very soft surface, you will want Soft Talalay for the top layer of your mattress or as a pillowtop. If you have children who mistake their beds for trampolines, we'd advise choosing a Dunlop latex mattress for them.
