Serta Mattress iSeries NXG 1500 Firm Hybrid King Mattress

The Serta iSeries NXG 1500 Firm Hybrid King Mattress delivers a balanced combination of support and comfort designed for a restful night’s sleep. This firm mattress features high-density NXG Memory Foam in a smooth, cool-to-the-touch fabric cover with carbon fiber-infused foam that draws heat away from the body for all-night cooling. Its hybrid construction includes a 5-zone coil system with alternating firm and plush areas to provide targeted support for the curves of your back and body, while BestEdge® technology ensures edge-to-edge stability. Motion is minimized, making it ideal for back or stomach sleepers, and the CertiPUR-US® certified foam guarantees a safe, chemical-free sleep surface. Designed for durability and compatibility with most bed frames, this mattress combines pressure relief, cooling, and support in a practical, long-lasting design.
