The latex raw material we use in our mattresses is imported from the Belgian company Latexco. Latex is produced by collecting the sap of the rubber tree and baking it in special molds. No raw material other than latex is used in block latex mattresses. Our Doa block latex mattress is designed with 7 zones to provide the right support to every part of the body with the joint work of Latexco and Munich Ergonomics Institute.
