Latex mattresses are very popular right now and their rise to prominence has resulted in the battle of the Talalay vs. Dunlop latex. It’s a silly argument, since it’s like comparing apples to oranges.
The terms Talalay and Dunlop are simply the methods by which latex is manufactured and has little to do with the quality of the end product.
It’s more important to find out what ingredients are put into the latex foam before, during and after either process is used to make the latex core. Ingredients to watch out for are harmful chemicals, toxic flame retardants, dyes, and substances that can break the latex down over time.
Still want the details?
In the Talalay process air is extracted from the latex foam and the latex is flash frozen, resulting in an "airier" latex. If you like a softer mattress, buy one made with Talalay latex.
In the Dunlop process, air is not extracted, and there is no freeze stage. The latex cell structure is less "airy". If you prefer a firm mattress, this is the latex core for you.
