My Take On The King-Sized Serta iComfort CF4000 Firm Mattress

by Jed Harrington

Are you living in a home that lacks a moderate sleeping solution? You're covered with the King-Sized Serta iComfort CF4000 Firm Mattress. This luxurious mattress offers impressive value to all buyers.

The Right Support

The King-Sized Serta iComfort CF4000 Firm Mattress is perfectly designed for back and side sleepers alike — boasting a comfort rating of five. However, I wouldn't recommend this mattress to stomach sleepers, who typically require a softer sleeping experience.

Many Forms of Comfort

The King-Sized Serta iComfort CF4000 Firm Mattress uses multiple foams for support, including Carbon Fiber Memory Foam, Ultra Cool PCM, and Air Support Foam. Carbon Fiber Memory Foam channels heat away from your body while you sleep, in addition to providing much-needed back and neck support. Ultra Cool PCM furthers this goal by creating a layer of extra-cool support that aids you in falling asleep faster, while Air Support Foam uses exclusive air-cushion technology to contour around the curves of your body. These foams are each exceptional in their own right, but create an unbeatable sleeping experience when put together.

Dependable Foundation

While foam and density are important factors in any mattress, the King-Sized Serta iComfort CF4000 Firm Mattress exceeds expectations with a dependable StabL Base Foundation. This optional foundation uses a V-shaped construction to isolate the impact of movement. This is particularly useful if you plan to share the mattress with a sleeping partner.

Great Coverage

In addition to the multitude of other features included in this mattress, the King-Sized Serta iComfort CF4000 Firm Mattress has a Max Cool Cover. This cover, made from high-performance fibers, delivers an impressive burst of instant cool-to-the-touch sensation, working to prevent tossing and turning while you sleep.

Fully Certified

Finally, the King-Sized Serta iComfort CF4000 Firm Mattress has a CertiPUR-US Certification. This certification proves the mattress has undergone rigorous, independent testing and met or exceeded quality expectations.

A Valuable Option

In conclusion, the King-Sized Serta iComfort CF4000 Firm Mattress is guaranteed to impress back and side sleepers alike. For a sleeping solution that will put your current mattress to shame, consider adding the King-Sized Serta iComfort CF4000 Firm Mattress to your home furniture collection today.
