What is the difference between Dunlop and Talalay Latex Foam?

The Dunlop and the Talalay are the two main processes used to create latex foam. There is a lot of information on the differences between these two processes, but in most cases, they are exaggerated, as they are retailers’ and manufacturers’ selling points.

No Big Differences

The number one difference between the two types of latex is that the Talaly process has two extra steps, which make it more expensive and less energy efficient.

In both cases they foam the liquid latex and pour it into the the mold. While in the Dunlop process they fill the mold up, in the Talalay process it is only partially filled, so that after sealing the lid of the mold, the latex can be expanded by vacuum to fill the mold. Once the latex has fully expanded, the mold is frozen. By pushing carbon dioxide through the latex, the latex will gel. After that, the temperature is raised to 110ºC as it is with the Dunlop process to vulcanize the latex. Finally, the foam is removed from the mold and gets thoroughly washed.

The average person would not notice much of a difference at all between the two types of foam. The two extra steps however make the Talalay latex more expensive.

Furthermore not all Talalay and not all Dunlop foam feel the same. Each of them can be made with or without synthetic latex and with or without added fillers.

 

Is Talalay foam softer than Dunlop?

They say that Talalay mattresses are always softer than Dunlop mattresses. That’s not true. Both Talalay and Dunlop latex foam can be produced in a wide variety of firmness.  The Dunlop process does create heavier, denser foam but this does not necessarily mean that the foam is firmer. Being firm and dense are two different things.

The 3 Main Differences

  • The production of Dunlop foam is more energy efficient
  • While Dunlop foams are springy, Talalay foams are bouncy
  • Dunlop foam is denser and heavier than Talalay foam

 

The Milam mattress is made of Dunlop latex foam as we believe that Dunlop foam works better for more people and not least it is better for the environment as the production is more energy efficient. Nevertheless, this is a personal choice.
