Dunlop Latex vs Talalay Latex
If you're confused about the difference between Dunlop and Talalay, here's how they differ.
Dunlop
Dunlop is the traditional manufacturing process that’s been in use since 1929. The latex serum is whipped in a centrifuge, poured into a mold, covered and baked. The natural sediments in the mixture settle to the bottom of the mold. This makes Dunlop layers slightly firmer on the bottom side.
Talalay
The Talalay process is more high tech. To make natural Talalay, after the latex is poured, the mold is sealed and the process continues in a vacuum. Then the mold is flash-frozen to stabilize the material. Because of the added steps, Talalay latex has a more consistent cell structure top to bottom and edge to edge, and it is more expensive than Dunlop. All Talalay pieces wider than 40" are seamed with Simalfa - a safe, water-based glue.
Which is better?
We can say with confidence that neither is superior to the other. What matters more is how the latex is handled out of the mold, how it is packaged, shipped, and ultimately, what is in the end product. What matters most of all is which type will feel better to you.
While it's true that Talalay has a wider range of ILD’s, or firmness grades, in our experience Dunlop is heavier and more durable. If you like a very soft mattress, you may want Talalay - at least for the top layer. (A layer of Soft Talalay is softer than a layer of Soft Dunlop.) If you have children who mistake their mattress for a trampoline, you will want Dunlop.
