Expert Review

My Take on the iComfort Hybrid CF4000 Plush

by Jed Harrington

The iComfort Hybrid CF4000 Plush is the best of the best, and perfect if you're looking for a mattres with leading technology and a not too firm, not too soft level of comfort.

Top of the line Cooling

The CF4000 Plush is all about promoting a cooler sleep environment for deep REM sleep. The Max Cold Cover, Ultra Cold System, and Carbon Fiber Memory Foam all provide cooling so powerful, you can feel it working through jeans. This is great because cooler sleep environments do a great job promoting better sleep.

Amazing new Comfort Technlogy

Carbon Fiber Memory Foam and Air Support Foam combine to produce a feel that's both comfortable and supportive. Exclusive to Serta, these components help reduce pressure points for less tossing and turning, and create a cooler sleep environment. Air Support Foam uniquely contours to your every curve and pushes back against the body for a more supportive feel.

Top of the Line Coil System

The 1025 iComfort Hybrid Support System with Best Edge Foam Encasement provides solid support while contouring to the curves of your body. This system helps isolate motion transfer when movement occurs for undisturbed sleep, and is adjustable base friendly. The Best Edge Foam Encasement keeps comfort consistent, even when sleeping to the edge.

A Great All Around Comfort

The Comfort Scale Rating of 5 on the CF4000 Plush is right in the middle (10 is the softest), and creates a not too firm not too soft feel that does a great job contouring to the curves of your body, without feeling overly soft. The exclusive Air Support system provides a really substantial and high end underlying feel.

Undisturbed Sleep

The CF4000 Plush produces a nearly motionless sleep environment, which means if movement takes place on one side, you'll feel less on your side.

The Best Firm Mattress in The Line

If you're looking for the best plush mattress in the iComfort Collection, this is the way to go. The CF4000 Plush is packed full of great components that promote cool, comfortable, and supportive sleep. The unique Air Support Foam system really does a good job working with the coil system to great a high end, top of the line feel. If you want the best, this is the way to go.
