Synthetic latex is a material used for mattress manufacturing that is produced from synthetic chemicals, rather than being extracted from the sap of the Hevea tree, the natural rubber tree. Synthetic latex is also known as artificial latex or synthetic latex.

The process of making synthetic latex involves the polymerization of styrene-butadiene monomers, a type of synthetic polymer, in a latex solution. Synthetic latex can also be produced from other types of monomers, such as acrylonitrile-butadiene-styrene (ABS) or polychloroprene, which are all synthetic polymers.

Synthetic latex has similar physical properties to natural latex, but may be inferior in terms of feel and elasticity. It is, however, cheaper to produce than natural latex, making it a more affordable option for mattress manufacturers.

Synthetic latex is generally produced in two forms: Dunlop synthetic latex and Talalay synthetic latex. Dunlop synthetic latex is produced by mixing base chemicals into a solution and then whipping them to create a foam. This foam is then molded and baked to create blocks of latex. Talalay synthetic latex, on the other hand, uses a more complex process that involves freezing the foam, followed by a decompression step to create a lighter, airier foam.

Synthetic latex mattresses offer many benefits, including good durability and high resilience. They also provide excellent support for the body, as the synthetic latex adapts to the shape of the body to reduce pressure points and promote proper spinal alignment.
