The Sweetnight CoolNest 14-inch King mattress is designed for hot sleepers and couples who need a cooler, more comfortable night's rest. This memory foam mattress features the innovative CoolNest System that combines PCM high-resilience foam with gel-infused memory foam to actively dissipate heat and maintain a cooler surface throughout the night.

Engineered with a 5-zone support system, the CoolNest mattress helps cushion pressure areas from head to toe while maintaining stability.

Build quality is solid with CertiPUR-US certified foams, ensuring durability and safety. The mattress comes compressed in a box for easy setup, though it requires up to 72 hours to fully expand. The 10-year warranty provides long-term assurance.
