iComfort CF 4000 Firm



The iComfort CF4000 Firm mattress is where luxury meets technology in the iComfort line.  Designed with technologies to maximize cooling on the sleep surface plus pressure relief and back support, the CF4000 mattresses are built to enhance comfort and sleep performance.

Top Layers of Comfort
Starting at the sleep surface, this model of mattress utilizes its coolest technology feature with a Max Cold Cover to achieve a balanced sleep temperature.  Directly beneath the cover find 1.5″ of high density Max Memory Foam for comfort followed by 1″ of Serta Support Foam to supply firmness on the surface.  Beneath these layers find 3″ of the exclusive Serta Air Support Foam to accomplish incredible loft and weight displacement for the sleeper.  The combination of these comfort layers helps to enhance pressure point relief while optimizing back support.

Core Layers of Support
The 8” Serta Ultimate Edge Foam Core is the foundation for the advanced iComfort CF mattress comfort layers. It provides a firm and long-lasting support system.

Our Recommendation
We recommend the Serta iComfort CF4000 Firm mattress specifically for a back or stomach sleeper.  Enhanced cooling features also make this a desirable option for those that sleep hot at night.
