Why Our Sleep Experts™ Love It

Plus, exclusive BestEdge® Foam Encasement offers extra reinforcement around the sides of the mattress, helping to maximize the sleep surface of your bed—so go ahead, stretch out as far as you can. If you want enhanced support and supreme cooling technology, all wrapped up in a luxuriously plush mattress, the Serta iSeries Hybrid 4000 is the bed for you. Don’t forget to complete your sleep with the Malouf® Supreme Sleep bedding collection and Serta Motion iSeries Adjustable Base.
Elevating the top and/or bottom of your mattress provides targeted support to help reduce snoring, provide pain relief and make reading and watching TV more comfortable.
Adjustable Base Friendly
Using pressure relief can alleviate aches, stiffness, pain, and sleep apnea by keep pressure on the mattress consistent across the entire bed.
Temperature-regulating components and materials draw heat away from the body to create a cool and comfortable sleep surface.
By working with manufacturers to reduce carbon emissions, utilize recycled materials and create biodegradable products, we're caring for you and the planet.
The goal of motion separation is to isolate movement, helping to reduce what you feel (like your partner tossing and turning) and offer pressure relief to your shoulders, hips, and back.
Proper support from your mattress can alleviate common sleep problems from snoring to soreness to sleep apnea as it distributes your weight evenly across the mattress and maintains proper joint and spine alignment.

Let's Look Under The Covers
Max Cold™ Cover
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.
Carbon Fiber High-Density Memory Foam with UltraCold System™
The 1” layer of pressure-relieving, high-density carbon fiber memory foam, combined with the UltraCold System™, channels heat away from your body to create a cooler sleep experience.
Comfort Foam Layers
2” of high-density EverCool® Fuze Gel Memory Foam, 1.5” of EverCool® Supreme Memory Foam, and 1” of EverCool® Fuze Gel Foam combine to provide a weightless, cradling feeling and extraordinary pressure relief for your curves.
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.
