Eco-Friendly Manufacturing

Rest easy knowing that the foam used in our mattress toppers are manufactured in the USA to the strictest environmental standards. We leverage a patented technology called Variable Pressure Foaming that uses an air-sealed chamber and carbon beds to scrub emissions - reducing emissions by 97% vs standard manufacturing. This process also helps to remove off-gassing and the need to "air-out" our mattresses before use.

Every MOLECULE mattress topper contains CertiPUR-US® foam.
