Key Features of the Serta iComfort Hybrid CF4000 Plush 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 covers’ 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 you 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.

EverCool® Fuze Gel Memory Foam- This breathable foam works with the other foams to help with temperature control and is infused with gel to provide conforming support and pressure relief.

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.
