Discover superior cooling and maximum comfort combined with supportive memory foam found in the SensorPEDIC Epic Chill Cooling Memory Foam Pillow Powered by REACTEX. This pillow is tested to be 20x cooler than standard non-REACTEX pillows to help you sleep comfortably throughout the night. Products with REACTEX technology feature pressure-activated cooling in approximately 8 seconds as heat is pulled away from the sleeping surface and stored away from the body to help skin temperature reach and maintain the optimal range for sleep. While not in use, the REACTEX technology releases stored heat energy to prepare for the next night's use. This pillow features double sided cooling technology combined with a breathable polyester fabric cover to offer cool relief for hot sleepers. The high profile memory foam provides head-cradling, pressure-relieving support ideal for side and back sleepers. The foam in this pillow is CertiPUR-US certified to meet rigorous standards for content, emissions and durability, and is analyzed by independent, accredited testing laboratories.
