2 inch thick natural latex; Flame retardant free; Free of harsh chemicals and odors; All natural and completely non-toxic; Wrapped in a thin layer of wool; Available in custom sizes! Our Natural Latex provides a soft and bouncy feel without the sharpness or gradual loss of elasticity of springs. And while all latex is a man-made material, our natural latex is derived from rubber tree sap and not synthetic elastic. This limits off-gassing and unnecessary addition of untested chemicals. Additionally, all our latex is made via a variation of the Dunlop Process called the Continuous Pour Process, which we believe makes for the most consistent and even latex product on the market. Our natural Dunlop latex is a "Medium" firmness. In Dunlop terms, it's considered a C3 class, which is a rough equivalent of a 32-ILD in Talalay. While initially quite soft and giving, the natural latex offers excellent support and weight redistribution, cradling the body.
