Serta's Best Plush Mattress

by Jed Harrington

Envelop yourself in comfort with the Serta iComfort CF4000 Quilted Plush California king mattress. The pinnacle of plush comfort, this mattress has a comfort rating of 5, which means it provides the right amount of softness while still affording support. If that sounds like the right level of softness to you, you’ll also love the other features that this mattress offers.

Sleep Cool With the Max Cold Cover

High-performance fibers are integrated into the surface of the plush mattress so that it always feels cool to the touch. Every time you get into bed, you’ll be surrounded by a cool, refreshing sensation that makes it easy to fall asleep.

UltraCold System Removes Excess Heat

The premium UltraCold cooling technology doesn’t just make the mattress feel cool, but it also helps you stay cool throughout the night. The system absorbs excess heat as you sleep so that you aren’t sweltering.

Foam Enhanced With Carbon Fibers

Woven into the foam is a network of carbon fibers that further helps cool and also provides support. The carbon fibers will cradle your back and neck while simultaneously further ushering away extra heat.

Exclusive Air-Cushion Layer

An exclusive air cushion feature makes it feel like you’re sleeping on air. The open-air cells contour around your body to eliminate pressure points.

Support That Fits

Supporting the plush mattress top is a foundation of individually wrapped springs that are able to act independent of each other. This allows each spring to adjust to your body for strong and pressure-free support.
