What Is a Latex Mattress?
Latex is a rubber particle suspended in liquid. Latex can be natural or synthetic. Natural latex comes from the sap-like extract of rubber trees. Synthetic latex is made by polymerizing a monomer that has been emulsified with surfactants. Synthetic latex has, however, the same basic properties of natural latex. All latex is either a natural / synthetic blend or 100% natural latex.
In addition there are two types of latex processing, Dunlop and Talalay.
Latex cores are the piece of latex used to make a mattress. They tend to be 5-6 inches thick and typically have a density of 4 lb/cubic foot or higher. They are made with pincore construction, meaning that the cores have hundreds of small holes in them. These holes help to circulate air within the latex core and soften the core by making it less dense.
It is not uncommon for latex beds to have at least one layer of another material, such as memory foam, on top of the latex core to provide a softer and more compliant feel.
Latex mattresses have been around for decades, but have not sold particularly well. Our research, however, has shown a significant increase in interest for latex mattresses by the public over the past several years. In addition, mattress manufacturers have been adding latex mattresses, or at least mattresses with a layer of latex, to their offerings. This increase in latex mattress popularity is likely due to various and fairly recent improvements to latex processing which have helped to make mattresses made with latex highly competitive with other mattress types.
