With a unique balance of support, cooling comfort and state-of-the-art hybrid technology, the Serta iSeries Hybrid 3000 mattress is the best of both worlds (and then some). It boasts a 13.5-inch profile and 4 inches of advanced memory foam, combined with individually wrapped coils for universal comfort and rejuvenating support. Plus, its medium feel is great for all sleepers—side, back and even stomach. On top, its high-performance Max Cold™ cover is cool to the touch. Underneath, a 1” layer of high-density Carbon Fiber Memory Foam and Serta’s exclusive UltraCold System™ work to absorb excess heat, channeling it away from your body for supremely cool sleep.
