The Zoned Gel Dough® king-size pillow provides optimal comfort for restful sleep by combining the cooling benefits of Gel Dough® with the comfort and breathability of Zones Technology™. The Gel Dough® formula creates a cooler, softer memory foam that maintains form for better support than traditional memory foam. Zoned Technology™ cradles the head while supporting the neck, providing impressive airflow that makes this one of the coolest, most breathable pillows around. A beautiful and soft Tencel™ mesh removable cover adds the temperature- and moisture-regulating comfort of eco-friendly fabric.
