Dunlop latex rubber is a high-quality, durable foam like material made from either natural latex rubber (NR), synthetic latex (SBR), or a blend of the two. Dunlop blends (NR/SBR) use various percentages of both natural and synthetic foams in their formulations.

The original Dunlop process for producing Latex rubber was developed in 1929. Dunlop process of latex fabrication has two main variations: one uses a mold and the other (more recent one) is done with a continuous pour method on a moving belt. The mold method is simpler and results in a denser foam. Continuous pour Dunlop can be made softer, but still dense and durable, varying little in terms of firmness throughout the material.

Dunlop is historically less expensive than Talalay and yields a denser/heavier, less airy, less consistent foam rubber, tending to be denser toward the bottom of the mold.

Synthetic or blended Dunlop is the least expensive (higher % of natural rubber increases the cost of the blend).

Dunlop is popular for its supportive characteristics as it does not compress as deeply with greater weight as opposed to its latex counterpart: Talalay. Mattress manufacturers tend to use it in the support layer of an all latex mattress. Regardless of the type, latex in general is the most temperature-neutral of all the foam materials.
