JERFIT 12 Inch California King Mattress, Firm Hybrid Bed in a Box with Copper Cooling Gel Memory Foam, Motion Isolation, Edge Support, CertiPUR-US Greenguard Gold Certified, Made in USA

JERFIT Cool-Touch Fabric with conductive yarns actively pulls heat away from the body for a consistently cool and comfortable sleep all night long. Copper-Infused Cooling Gel Memory Foam regulates temperature by drawing excess heat away from your body while contouring to alleviate pressure points. 740 Individually Wrapped Pocketed Coils provide targeted support, reduce motion transfer, and enhance overall durability. Dynamic Edge Support System features a reinforced perimeter that prevents sagging and provides a larger, more stable sleep surface. High-Definition Transition Foam Layer enhances the buoyant, weightless feel and creates a seamless transition from the responsive coils to the comfort layers. Firm Feel offers supportive, pressure-relieving comfort that is ideal for back and stomach sleepers or those who prefer a more solid sleep surface. CertiPUR-US Certified foams ensure the mattress is made without harmful chemicals and is low in VOC emissions for indoor air quality. GREENGUARD Gold Certified verifies that the mattress meets strict standards for low chemical emissions, contributing to a healthier indoor environment. Hybrid Design in a Box combines the contouring benefits of memory foam with the responsive support of an innerspring system for the ideal sleep experience.
