Construction & materials

	MOLECULE 1	Zotto
Layers	Restoreflo™, Recoveryflo™, Contourflo™	Thermaphase comfort layer, CoolFlow Support Layer, Transition Layer, Base Layer
Cover	Our advanced cover features a unique combination of heat and moisture wicking technologies to regulate the microclimate between your body and the sleep surface. Microban® treatment helps prevent the growth of odor and stain-causing bacteria for a cleaner sleep.	Our proprietary Poly+Rayon cover is not only soft as silk-wrapped marshmallows, its tough enough to withstand anything life can throw its way. The cover is also removable and machine washable.
Machine-washable cover	No	No
Ergonomic handles	No	No
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 top layer, the ThermaPhase comfort layer, is the culmination of years of development. Our comfort layer combines two different phase-change materials that target temperatures on both ends of the optimal sleep zone. Upon reaching an ideal sleeping temperature, the phase change material undergoes a molecular transformation that works to maintain the temperature at the optimal level. This results in a mattress that will keep you cool when its warm, and will help keep you warm when its cold. There is not a more technologically advanced, or more comfortable mattress available, period. Our ThermaPhase comfort layer, is the culmination of years of development. We combined two different phase-change materials that react to temperature fluctuation. The result is a "Smart" mattress that will react to heat and actively cool the sleeping surface. OR if sleeping conditions become too cold, the Thermaphase molecules will redistribute absorbed heat to help keep you warm.
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.	Each layer was engineered with varying levels of density and weight capacity to provide dynamic support. Our top 3 layers are a patent pending hybrid-foam package that we call Z3. The Z3 package utilizes various pressure ratings that only engage when necessary, providing the right amount of support and comfort for any size user, and optimal pressure point relief for back and joint pain.
