The King-Sized Serta iComfort CF3000 Medium Mattress is value-oriented and promises a restful sleep for back and side sleepers alike — boasting a comfort rating of four. However, I wouldn't recommend this mattress for stomach sleepers, who typically require a much softer sleeping experience.

The King-Sized Serta iComfort CF3000 Medium Mattress includes a number of unique foams for support, including Carbon Fiber Memory Foam and Ultra Cool PCM. Carbon Fiber Memory Foam channels heat away from your body and provides much-needed support to your back and neck. Ultra Cool PCM is a phase change material that provides a cooler sleeping surface, making it possible to fall asleep faster with less tossing and turning throughout the night. These foams, together, will contour to the curves of your body and keep you sound asleep.

In addition to comfortable foams and an ideal comfort rating, the King-Sized Serta iComfort CF3000 Medium Mattress includes a StabL Base Foundation. This optional foundation utilizes a V-shaped construction that isolates the impact of movement, making it that much easier to share your mattress with a sleeping partner.

As if this mattress didn't have enough to offer, the King-Sized Serta iComfort CF3000 Medium Mattress has a Max Cool Cover. This cover is made from high-performance fibers that deliver an instant burst of cool-to-the-touch sensation.

Finally, the King-Sized Serta iComfort CF3000 Medium Mattress has a CertiPUR-US Certification. This certification simply proves the mattress has been through a rigorous, independent testing process and met or exceeded expectations.

Put simply, the King-Sized Serta iComfort CF3000 Medium Mattress is a wonderful choice for back and side sleepers alike. For a well-rounded mattress that guarantees lasting success, consider adding the King-Sized Serta iComfort CF3000 Medium Mattress to your master bedroom, guest room, or living space today.
