Only available from Hammacher Schlemmer, this is the pillow that harnesses infrared energy to help reduce muscle stiffness in the neck. Each side of the pillow contains 110 1/4" diameter pads made with a thermo-reactive material that converts released body heat into therapeutic infrared light that is reabsorbed back into the skin. The invisible infrared energy penetrates deep into muscles to promote circulation and help counteract the chronic aches and inflammation that can impact a night’s rest. The pillow ensures comfort and correct posture for side, back, and stomach sleepers by eliminating pressure points with slightly raised edges. With a hypoallergenic down alternative polyester fill. White cotton cover. 27 1/2" L x 16" W x 5" D. (2 1/2 lbs.)
