Serta iComfort CF4000 Quilted Hybrid Extra Firm Mattress Review
Updated January 26, 2022
The iComfort CF4000 Quilted Hybrid Firm mattress is the top-of-the-line firm model in the newest iComfort collection from Serta. For a model that's called a 'firm', this mattress actually feels more in the middle of our 10-point comfort scale at a 4 rating. It exhibited excellent pressure relief and body contouring during our pressure testing. For more information about this bed please read on:
Comfort Scale Rating
The CF4000 Quilted Hybrid Firm mattress is expected to be a very firm comfort that we'll probably rate a 2 on our 10 point Comfort Scale (a 1 is hard, 10 is softest.) A mattress with this comfort will work nicely for people who like a firmer feel, or something in the middle between soft and firm.

The iComfort CF4000 Extra Firm
Pressure Test Results
We've pressure tested the iComfort CF4000 Quilted Hybrid Firm mattress with small, average, and large body size people on their sides and on their back sleeping positions to see what kind of support and pressure relief you can expect. (Learn how we test.)
The mattress performed extremely well for back sleepers and fairly well for side sleepers. Despite being called a 'firm' mattress, the CF4000 is actually more towards the middle of our comfort scale. It's for this reason that the pressure relief shown in the images below is so good for four out of the six body size/sleep position combinations. This bed earned four 'recommended' scores for its ability to relieve pressure on the hips and shoulders while providing contouring support for proper spinal alignment.
As you consider the CF4000 Firm for your next new mattress please feel free to consider our pressure mapping technology in your considerations:

Conclusion
The CF4000 Quilted Hybrid Extra Firm is one of three CF4000's at the top-end of the iComfort Quilted Hybrid collection. While it's the firmest of the three CF4000's in the Quilted Hybrid collection, it's nowhere near what we'd call a true 'firm' feeling. The three snowflakes stitched into the cover at the foot of the bed show you that this mattress has many layers of cooling materials.
A layer of Carbon Fiber Memory Foam paired with the UltraCold System™ channels heat away from your body. More comfort is derived from the Deep Reaction™ Max Memory Foam. Serta's exclusive Air Support™ Foam contours to your body and helps relieve aches and pain caused by pressure points. This premium plush mattress is one of the coolest sleeping iComfort models ever.
I don't make ridiculous money writing mattress reviews, I live paycheck to paycheck just like nearly everyone. I think that this bed, priced at $2,699 for a Queen size, is a pretty expensive buy. That said, for anyone who wants a medium-firm comfort bed with all the trimmings, then this is one of the best mattresses you could get. If you still want one of these iComfort Hybrid models but can't afford the steep tab, check into one of the other models, the price swing is as large as $1,000!
