GoodBed Expert Review
Our Take on Serta iComfort Hybrid CF4000 Firm
Michael Magnuson
Founder of GoodBed, Leading Mattress Expert
BEST if you
- Want a firm mattress
- Are mainly a back sleeper (though this mattress can also be very good for stomach sleepers) (though this mattress can also be good for side sleepers who prioritize firm support over extra pressure relief)
- Enjoy being hugged or cradled by your mattress
- Prefer a slightly above average amount of 'memory feel'
- Would like a mattress that performs very well when used with an adjustable base
- Like a little bounce in your mattress, but not much
NOT IDEAL if you
- Have a strong tendency to sleep hot (temperature regulation is pretty good, but not the best)
- Regularly sit or sleep along the edge of your bed (edge support is good, but not the best)
- Tend to have difficulty changing positions during the night (though ease of repositioning is still OK)
- Prefer products that have been more extensively tested by GoodBed
- Want a natural or organic mattress

Yes, the Serta iComfort Hybrid 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 Hybrid Firm to have very good adjustable base compatibility.
