The core of our Latex Mattress includes 9 inches of GOLS-certified organic latex. From top to bottom, that consists of a 2-inch layer of GOLS-certified organic Dunlop contoured latex (D65), 3 inches of GOLS-certified organic latex (D75), and another 4-inch layer of GOLS-certified organic latex (D75), plus a thin layer of GOTS-certified organic cotton.
We craft the top panel with organic cotton over a generous layer of organic wool with thin non-woven backing as a natural fire barrier, per Global Organic Textile Standard (GOTS) accessory requirements (required to keep the organic materials from shifting during production and to ensure the natural fibers do not clump or "work" through the cotton layers over time). We construct the side panels similarly, adding a GOTS-certified organic needle-punch wool layer as a natural fire barrier. The bottom panel is the same as the side panel but uses GOTS-certified organic cotton canvas in a herringbone pattern instead of organic cotton.
