GoodBed Expert Review
Our Take on Serta iComfort CF4000 Firm
Michael Magnuson
Founder of GoodBed, Leading Mattress Expert
BEST if you
- Want a firm mattress
- Are mainly a side sleeper (though this mattress can also be very good for back sleepers)
- Are easily disturbed by other movements in the bed (motion isolation is excellent)
- Prefer an above average amount of 'memory feel'
- Enjoy sleeping just a bit more 'in' your mattress than 'on' it
- Prefer products that have been more extensively tested by GoodBed
NOT IDEAL if you
- Are a stomach sleeper, especially if you weigh more than 250 lb
- Like your mattress to have some bounce
- Frequently sit or sleep along the edge of your bed (edge support isn't the best, but is still pretty good)
- Tend to have difficulty changing positions during the night (though ease of repositioning is still pretty good)
- Want a natural or organic mattress

Yes, the Serta iComfort CF4000 Firm mattress is adjustable base compatible. This means it is designed to be used on an adjustable base without incurring damage or voiding the warranty. In our review of this mattress, we tested it on an adjustable base to look for any adverse effects as the head and foot are elevated, and to see how well it conforms to the contours of the base both with and without the weight of a sleeper. Overall, we found the CF4000 Firm to have good adjustable base compatibility.
