From cover to core, every inch of the MOLECULE Reflex Hybrid X Mattress is engineered for ultimate sleep recovery. It features six layers of our most advanced foams and technology, and an ultra thick, 14-inch design for our most luxurious medium feel. The plush cover combines foam and pillowy fiber for instant pressure relief from the moment you lie down. Dual layers of high-airflow foams ventilate for maximum cooling comfort. A zoned support layer and ultra-targeted LiftCOR™ technology gently lift your back and core. This encourages natural spinal alignment for more time spent in deep sleep. At the base, a robust zoned innerspring system with precision-placed, low-gauge, pocketed coils adapt to your body in any position. It's a superior sleep experience that delivers the deep, nourishing rest you need to unlock your body's full performance potential.
