The OrganicPedic Earth™ Pinnacle™ is an extra-plush 13” sculpted-surface pillow-top organic mattress made with GOLS-certified organic natural rubber latex. It starts with a 4” core of medium, supportive latex. The core is joined with 3” of firm sculpted-surface latex on the top and 2” of firm latex on the bottom. The organic mattress is then covered in our signature certified organic cotton and wool quilting. A removable, two-sided pillow top (3 1/2” deep) – also made of 100%-natural rubber latex – is then placed on the organic mattress. The pillow top is made with two surface options: our exclusive sculpted surface on one side, and a flat surface on the other. This provides sleepers with maximum comfort and flexibility. The pillow top is fully covered with our signature GOTS-certified organic cotton-and-wool quilting, and is attached to the organic mattress using our exclusive “button-down” process.
