Latex mattress is used as a top layer in traditional innerspring mattresses. They are preferred by people who are into the green movement” because natural latex is made from the sap of a rubber tree. As such, it has unparalleled buoyant and elastic properties compared to other “green” mattress materials like cotton and wool.
Latex is also hypo-allergenic, anti-bacterial and has anti-dust mite qualities, meaning, that these little pests will not thrive in latex, and so you are able to enjoy your mattress for a long, long time without any discomfort. It does not feel hot on the skin; it resists packing down and has body formation qualities. And because it is “green”, it is perfect for those who have allergy concerns and other chemical sensitivities.
Botanically derived Natural Latex is very responsive and resilient, provides a buoyant sensation when sleeping which keeps you on top of your bed, rather than feeling you are sinking, collapsing or caving in, found with so many conventional and regular mattresses. Because it so extremely elastic, natural latex mattress makes you to turn easily, while distributing your weight to the entire bed, and reducing pressure points to avoid back and neck pains, therefore improving your sleep hygiene.
However, there is a latex mattress that comes in synthetic form. Its production started during World War II. They are formed using two methods: the original Dunlop method, considered as the longstanding and traditional method that is essentially employed for making natural latex and the newer Talalay method, the one used for making the synthetic kind.
Two Processes in Manufacturing Latex
In making the natural kind of latex mattress, natural latex is collected by hand, poured into vats, filtered then poured into large moulds, emulsified with air and water bubbles, slowly heated, and vulcanized where the liquid latex rubber is then turned into a solid state. During the vulcanization process, the Dunlop or Talalay method are either employed.
The Dunlop method yields more support and results to a slightly firmer natural latex while the new method adds the flash freeze process which is responsible for the suspension of the smaller air bubbles into the mold before it is quickly heated for the solidification process, which results to a slightly softer and less supportive feel.
Latex formed from the Dunlop process is less expensive, gives better support for sleeping, and is more eco friendly.
