The Cal King-Sized Serta iComfort CF4000 Plush Mattress offers a comfort rating of seven and is perfect for stomach sleepers. I wouldn't recommend it for side or back sleepers, who typically require a firmer sleeping surface.Fantastic Comfort
In the Cal King-Sized Serta iComfort CF4000 Plush Mattress, you'll find Carbon Fiber Memory Foam, Ultra Cool PCM, and Air Support Foam for support.

Finally, Air Support Foam contours to your body and works to alleviate aches and pains. Together, these foams provide an exemplary sleeping experience.Versatile Foundation
