GoodBed Expert Review
Our Take on Serta iSeries Hybrid 4000 Plush (2021-2024)
Founder of GoodBed, Leading Mattress Expert
BEST if you
- Want a soft mattress
- Are mainly a side sleeper
- Are easily disturbed by other movements in the bed (motion isolation is excellent)
- Have a clear preference for being hugged or cradled by your mattress
- Prefer an above average amount of 'memory feel'
- Would like a mattress that performs very well when used with an adjustable base
- Like a little bounce in your mattress, but not much
NOT IDEAL if you
- Are a stomach sleeper, especially if you weigh more than 250 lb
- Often sleep close to the edge of your bed (edge support is just OK)
- Have a strong tendency to sleep hot (temperature regulation is OK, but not the best)
- Tend to have difficulty changing positions during the night (though ease of repositioning is still OK)
- Want a natural or organic mattress

General Description
Its plush top features a cool-to-the-touch Max Cold Cover, a layer of high-density Carbon Fiber Memory Foam and Serta’s exclusive UltraCold System. This cooling technology works hard while you sleep to absorb excess body heat and channel it away, keeping you cool and comfy. Next, a Hybrid Support System is engineered with individually wrapped, 1025-density coils that provide curve-hugging comfort and exceptional support from your head to your toes. Plus, exclusive BestEdge Foam Encasement offers extra reinforcement around the sides of the mattress, helping to maximize the sleep surface of your bed.
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.
UltraCold System
- 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.
