Product Description

The New Serta iComfort CF4000 Firm Mattress features Serta’s most advanced materials focusing on keeping you cool. Layers of Carbon Fiber Memory Foam and the Ultracold System™ work together to pull heat away from your body, keeping your body at an ideal sleeping temperature. Multiple contouring layers conform, support, and relieve aches and pains caused by pressure points. This superior mattress is one of the coolest and most supportive iComfort models yet.

Key Features of the Serta iComfort CF4000 Firm Mattress:

Max Cool Cover- This cover is made from super cool high-performance fibers that are designed to provide an instant cool-to-the-touch feel to prevent you from overheating at night. A cool sleeping environment helps you fall asleep faster and stay asleep longer without interruptions.

UltraCold System™- An extra cool Carbon Fiber Memory Foam layer mixed with Phase Change Material works to absorb excess heat from your body, then dissipates that heat away so, you can sleep comfortably all night long.

Carbon Fiber Memory Foam- Made specifically for the New Serta iComfort foam mattresses, this exclusive foam features carbon fiber memory foam mixed with Phase Change Material (PCM). This foam is designed to draw heat away from your body and provide incredible support and pressure relief for your entire body.

Deep Reaction™ Max Memory Foam- Is a firm deep cushioning foam that conforms to the curves of your body, providing substantial pressure relief.

Serta® Support Foam- Is an extra firm foam that gives this mattress a firm yet comfortable supportive feeling.

Air Support™ Foam- This unique support layer features air-cushion technology that contours the curvatures of your body and moves with it to mitigate aches and pains caused by pressure points.

Serta® Foam Core- The foam core is incredibly durable and provides excellent support throughout the entire mattress while providing exceptional body contouring.
