All of our mattresses and sleep products are made exclusively from natural organic certified latex foam. It is made from an all-natural sap that is gently tapped from organically managed Heveay trees. We use pure organic cotton for all of our mattresses, pillows and toppers. It is naturally breathable, does not require any synthetic additives and does not make you uncomfortably hot while you sleep. Organic cotton is made without chemical fertilizers, insecticides, pesticides or herbicides and uses 91% less water than regular cotton. Much better for you and your health and, like our organic latex foam, a renewable raw material.
