Naturally derived from the milk of the tropical rubber tree, Talalay foam provides the ultimate in natural pressure relief and instantaneous, conforming support. It gently pushes back against the weight of the body to provide progressive support while alleviating pressure better than any other material on earth. And all latex foam is not created equal. The Talalay process allows for more density variations so that layers of material can be combined to further enhance dynamic contouring and pressure relief. Our latex is also made in the USA at an environmentally friendly facility.
