No. Manufacturers can have variations in their Dunlop and Talalay processes that can cause their final products to feel different, meaning all Dunlop foam doesn’t feel exactly the same, nor does all Talalay foam. For example, two Talalay mattresses of the same firmness level made by two different manufacturers might have slightly different responsiveness, textures, or densities. Keep in mind both kinds of latex come in the full range of firmnesses, meaning a soft Dunlop mattress is not going to feel the same as a medium or firm Dunlop mattress made by the same company, and the same holds true for Talalay as well.
