No other pillow can compare - because no other pillow features the same level of sophisticated engineering and innovation. Using the same cushioning technology developed for Purple mattresses, the Purple Harmony Pillow features a layer of honeycomb-patterned Purple Grid(R) Hex surrounding a supportive inner core of hypoallergenic ventilated latex. Wrapped in moisture-wicking, breathable mesh material, the no-pressure, supportive combo offers cool comfort all night long and never falls flat.
