About This [Individualized Support]: Each coil is individually wrapped and operates independently, providing tailored support and pressure relief based on the sleeper's body weight and movements. [Enhanced Comfort]: The hybrid design combines the adaptive comfort of foam with the responsive support of pocket coils, creating a perfect balance of pressure relief and spinal alignment for all sleeping positions. [Motion Isolation]: Pocket coils minimize motion transfer, ensuring an undisturbed night's sleep even if your partner moves during the night. [Breathability and Temperature Regulation]: The edge-to-edge pocket coil system allows for better airflow compared to traditional closed coil systems or dense foam mattresses. This increased ventilation helps dissipate heat and maintain a comfortable temperature throughout the night. [Better Edge Support]: The edge-to-edge coil structure offers consistent support, preventing sagging or roll-off along the edges.
