Comfort	Proprietary foam features exceptional pressure relief combined with enhanced airflow properties. Precision-contoured 3D geometric surface provides targeted, self-adjusting support for different parts of the body.	Our materials come from nature - whether it be wool sustainably sheared from New Zealand sheep or latex tapped from trees. These premium materials are comfortable on your body and conscience. 100% all natural & organic Birch Wool provides unparalleled comfort and temperature regulation. Birch Wool is designed to retain shape with a natural elasticity of each fiber. Talalay latex is up to 7 times more breathable than other types of latex. Natural latex is also hypoallergenic and anti-microbial.
Support	The foundation of the MOLECULE mattress. An ample 7” of firm support fosters healthy spine alignment. Breathable materials promote even more airflow and heat transfer.	We spent countless hours finding the right density of latex, quantity of wool, and type of steel springs to provide unprecedented comfort and pressure relief. Each mattress features a reinforced perimeter for best in class edge support. The coils that run along the outside of your mattress are actually firmer, so no more feeling of falling off the bed when lying down or sitting on the edge. Natural Talalay latex provides response to cushion your pressure points while giving support. Our latex is carefully managed to ensure consistency. Hundreds of individual steel coils help to cradle your body and provide support, while also limiting motion transfer. Additionally, the reinforced perimeter coils provide best in class edge support.
