About Natural Latex Mattresses
What is Natural Latex?
Natural Latex is a milky substance harvested from rubber tree plants. Harvesting the liquid latex is similar to tapping trees for maple syrup. The extraction process does not harm the trees, which provide a sustainable resource for production. Natural Latex is bio-degradable and naturally resistant to mold, mildew and bacteria.
There are two types of Natural Latex, Dunlop and Talalay; each is named after the manufacturing process used to produce it.
What are the benefits of Natural Latex Mattresses?
Natural Latex conforms to your body shape relieving pressure points. It is chemical-free and produces no harmful off-gassing. It is also “breathable” and stays cool unlike synthetic foams which hold heat. A natural latex mattress provides excellent support and reduces motion transfer so you are less likely to disturb your sleep partner (or they you). It has excellent shape retention and maintains its resiliency for many years. Learn more about our chemical-free Natural Latex Mattresses.
What is the difference between Dunlop and Talalay Latex?
Latex manufacturing has used the traditional Dunlop method since the late 1920’s and, although updated, the basic process is essentially the same. A thick rubber sap, or serum, is whipped into a froth in a centrifuge, poured into a mold, covered, and steam baked. Natural sediments in the mixture sink to the bottom of the mold which make every Dunlop layer slightly firmer on the bottom than the top. In a cross section of Dunlop latex foam you will see variation in the open cells that run throughout the foam due to the settling of suspended particles. Mattresses made with Dunlop latex will gently yield to your body’s shape while providing firm support.
The Talalay process adds two additional steps to the manufacture of latex. After the mixture is poured, the mold is vacuum sealed and the latex flash-frozen before baking. Talalay latex has a more consistent cell structure from top to bottom and edge to edge as the flash freezing prevents natural particles from settling. A cross section of Talalay latex will have smaller, more consistent cells throughout the foam. Due to the extra steps and equipment involved in making Talalay latex, it is more expensive to produce than Dunlop. A mattress made with Talalay latex will be softer and more buoyant than its Dunlop counterpart.
