Serta iComfort Quilted Hybrid CF4000 Extra Firm Mattress

The Serta iComfort Quilted Hybrid CF4000 Extra Firm Mattress is the top-of-the-line mattress in this new innovative line. Serta has revamped the iComfort Quilted Hybrid mattress collection to be more supportive and cooling. The Max Cold™ Cover and UltraCold System™ work together to draw heat away from your body while contouring memory foams and innerspring coil system support and relieve pressure points. If you are a stomach or back sleeper who likes a very firm mattress then the CF4000 Extra Firm Mattress is for you.

The Serta iComfort Quilted Hybrid CF4000 Extra Firm Mattress features Serta’s most advanced materials focusing on keeping you cool. Layers of Carbon Fiber Memory Foam and gel memory foam work together to pull heat away from your body, keeping your body at an ideal sleeping temperature. An advanced coil system provides conforming, pressure-relieving comfort, support, and motion separation. This superior quilted hybrid mattress is one of the coolest and most supportive iComfort models yet.

Key Features of the Serta iComfort Quilted Hybrid CF4000 Extra Firm Mattress:

Max Cold Cover- This cover is made from a smooth, stretchy, super cool high-performance material giving you an instant cool-to-the-touch sensation. Because of this cover’s thin stretchy design, there is no barrier between you and the cooling, contouring layers of the mattress. A cool sleeping environment helps you fall asleep faster and stay asleep longer without interruptions.

UltraCold System – Premium cooling technology just below the cover of the mattress is designed to absorb excess heat from your body while you sleep cool and comfortable throughout the night.

Carbon Fiber Memory Foam – Made specifically for the New Serta iComfort 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.

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.

1025 iComfort Hybrid Support System – Serta’s newest and most advanced innerspring coil system features individually wrapped coils that work independently to contour to every curve of your body and provide durable support and motion separation so, you can sleep soundly without interruption when you or your partner change positions during the night.

BestEdge Foam Encasement – Surrounding the entire mattress is a high-density foam providing additional strength and support around the edge of the mattress.
