Features
- CoolNest System for a Cooler Night - The CoolNest 12-inch king mattress features our innovative CoolNest System, combining PCM high-resilience foam with gel-infused memory foam for layered cooling comfort. This advanced system helps dissipate heat and maintain a cooler surface throughout the night, creating a cooler and more comfortable sleep environment for hot sleepers.
- 5-Zone Support for Pressure Relief - Engineered with a 5-zone design, this king size foam mattress integrates support foam and comfort foam to help cushion pressure areas from head to toe. It helps redistribute pressure while maintaining stability and balanced support for enhanced comfort. Recognized by the American Chiropractic Association (ACA), it's designed to promote a more restful sleep experience.
- Motion Isolation for Undisturbed Sleep - Constructed with multiple layers of memory foam, the CoolNest 12-inch king foam mattress helps absorb motion and reduce vibrations. Additionally, these layers work synergistically to minimize motion transfer, so you're less likely to be disturbed whether your partner shifts positions or gets up during the night. Wake up feeling more refreshed.
- Enhanced Breathability for Cooler Comfort - The CoolNest cover incorporates 3D-woven technology, featuring a ventilation pore design that improves breathability by 35% compared to standard fabrics. Also, the PCM high-resilience foam with a hollow structure promotes 3X airflow. Together, these features help to wick away moisture and adapt to body temperature for a cooler, drier sleep surface.
- Restful Sleep & King Mattress in a Box - The Sweetnight CoolNest gel-infused memory foam mattress features CertiPUR-US certified foams and certified cover, which provides a comfortable sleep environment. The 12-inch memory foam king mattress is compressed in a box for easy setup. Additionally, it comes with a 10-year protection. Please allow the Sweetnight mattress to fully expand for 72 hours.
