Our Take on Serta iComfort CF4000 Ultra Soft
Michael Magnuson
Founder of GoodBed, Leading Mattress Expert
BEST if you
- Want a very soft mattress
- Are mainly a side sleeper
- Are very easily disturbed by other movements in the bed (motion isolation is exceptional)
- Have a clear preference for being hugged or cradled by your mattress
- Prefer an above average amount of 'memory feel'
- Would like a mattress that performs very well when used with an adjustable base
- 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
- Sleep close to the edge of your bed sometimes
- Have a natural tendency to sleep hot
- Like a fair bit of bounce in your mattress
- Tend to have difficulty changing positions during the night (though ease of repositioning is still OK)
- Want a natural or organic mattress

Yes, the Serta iComfort CF4000 Ultra Soft 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 Ultra Soft to have very good adjustable base compatibility.
