As we mentioned earlier for mattress to be labeled Organic all its components and layers must be organic and meet the standards of either USDA NOP or GOTS.
Organic cotton, wool, bamboo or silk cover will usually make the top layer. Most of the time manufacturers use organic wool as a natural fire retardant material. Comfort layers are made from lower density organic latex, organic cotton or organic wool padding. The support layer is made from high-density organic latex core.
