What's the difference between natural and synthetic latex

Latex is a natural material that is derived from the sap of rubber trees. It is used in a variety of products, including mattresses, pillows, and other bedding materials.

There are two main types of latex: synthetic latex and natural latex. Synthetic latex is mostly made from a petrochemicals base and does not come from a natural source. It is generally less expensive than organic latex, but may not have the same properties or durability.

Natural latex, on the other hand, is derived from the sap of rubber trees and is considered to be a more sustainable and environmentally friendly option. 

It's important to note that latex can be labelled as "natural" and contain synthetic materials. Only organic Dunlop latex and all natural Talalay are made without synthetic latex. You can verify the integrity of the organic Dunlop by viewing the GOLS Organic certification. As for the Talalay, it must originate either from Latex International or Radium.

Natural latex can be processed in two different ways: the Dunlop process and the Talalay process.

The Dunlop process involves pouring the raw latex into a mold and allowing it to cure and solidify. The resulting latex is denser and more durable, but may not be as bouncy as Talalay latex.

The Talalay process involves adding air to the raw latex and freezing it before curing and solidifying it. This process results in a latex that is more bouncy and has a softer feel, but may not be as durable as Dunlop latex.

GOLS certified "Organic" latex is natural latex that has been grown and processed using methods that are environmentally friendly and sustainable. It is typically more expensive than non-organic natural latex, but some people feel that the additional cost is worth it for the environmental benefits and potential health benefits of using organic materials.

Under the GOLS content standard the latex must:

• contain at least 95% organic latex content
• not contain any synthetic latex

In addition to the purity and performance standards GOLS standards also includes many other important health and social guidelines.

Some of the other important parameters included in the certification include:

• VOC and harmful substance testing
• forest stewardship practises
• waste and pollution management
• water management regulations
• renewable energy requirements
• living wage guidelines for workers
• child labour is prohibited 

It's important to do your research and consider your personal needs and preferences when shopping for a mattress made with latex.
