Serta iSeries Hybrid 3000 Medium - Mattress Reviews (2024)

‹ ›

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" profile and 4" 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. Next, its Hybrid Support System is precisely engineered with individually wrapped, 1025-density coils that provide curve-hugging support from head to toe. Plus, Serta’s BestEdge Foam Encasem*nt offers extra reinforcement around the edges of the mattress, extending your sleep surface.

Comfort Foam Layers

• 1.5" of EverCool Supreme Plush Memory Foam.
• 1.5" of Deep Reaction Memory Foam.
• 0.5" of EverCool Fuze Gel Foam give you a weightless, cradling feeling all over your body for immense pressure point relief and support.

Max Cold Cover & UltraCold System

• One touch of the Max Cold Cover and you’ll discover what upgraded cooling technology in a mattress is. It’s exactly what the name says—maximum cold-to-the-touch softness that keeps even the hottest sleepers comfortable night after night. Serta’s exclusive UltraCold System is a phase change material that draws excess heat away as you sleep, stores it, and then slowly releases it as you move or your temperature drops. This keeps your body temperature from spiking or plummeting—and all the fussiness that comes with it—for a more satisfying sleep.

1025 iSeries Hybrid Support System

• In this advanced, 1025-coil-density innerspring system, individually wrapped coils work independently to conform to every curve and provide durable, firm support, and it provides motion isolation for less disruption as you or your partner shift and move. Plus, each 8" coil is individually wrapped for a quieter, more peaceful sleep.
