Even though latex mattresses have been around for quite some time, natural latex mattresses have recently become the next big thing in the mattress industry. In general, natural latex mattresses share many of the same characteristics as the popular synthetic memory foam mattresses except natural latex is 100% natural and biodegradable. Natural Latex or Natural Rubber comes from the Rubber Tree (Hevea Brasiliensis) and it's acquired by collecting a latex serum from the latex ducts of the Rubber Tree and then used to make Natural Latex. Unlike synthetic latex, natural latex is naturally hypo-allergenic, dust mite resistant and anti-microbial. It's breathable qualities allow it to keep cool in the summer and warm in the winter and it is the most naturally durable and cushioning material available in nature in addition to being biodegradable. The basic construction of a latex mattress is as follows:
Organic Natural Latex Mattress Materials
Natural latex mattress are made of a natural latex core, usually comprised of 1-4 layers of natural latex which provide the main support for the body. The latex core is then covered in multiple layers of organic cotton for additional comfort and natural wool which acts as a natural fire barrier and naturally wicks away moisture from the body for a more comfortable night sleep. Natural latex mattresses are great for people who sleep on their side as the natural latex conforms to the shape of the body for proper spinal alignment while sleeping.
LATEX PRODUCTION TECHNIQUES
There are two different production processes used to make latex mattresses and are described below:
The oldest and most established process of processing latex mattresses (dating back over 75 years) is called Dunlop. The Dunlop process involves whipping the wet latex with air until it becomes a latex foam. It is then poured into a mold and hardened into the elastic latex or rubber that we are familiar with. Dunlop latex tends to be firmer and a bit heavier than Talalay processed rubber. The following manufacturers offer Dunlop processed latex mattresses- Pure Rest
The newer, more involved and more expensive processes is called Talalay. In the Talalay process the liquid rubber is also poured into a mold, but extra room is left at the top of the mold. The air is then vacuumed out of the mold which causes the natural latex foam to expand and fill the mold. The result of the newer Talalay process is a softer and less dense material. The following manufacturers offer Talalay processed latex - Royal Pedic
Which Is Better, Dunlop Or Talalay?
We can confidently say that neither process is better than another. What matters more is how the purity of the latex and how it is handled out of the mold, how it is packaged, shipped, and ultimately, what is in the end product. The most important factor is which type fells better to you. Both materials make a great mattress, have a great lifespan and are extremely pure relative to materials used in conventional mattresses.
