GoodBed Expert Review
Our Take on Serta iComfort CF4000 Soft

Founder of GoodBed
Michael Magnuson

Founder of GoodBed, Leading Mattress Expert

Bottom Line - Here was our assessment of this product.
Bottom line best icon BEST if you
  • Want a medium-soft mattress (i.e., just a little softer than average)
  • Are mainly a side sleeper
  • Are easily disturbed by other movements in the bed (motion isolation is excellent)
  • Prefer a mattress with lots of 'memory feel'
  • Enjoy being hugged or cradled by your mattress
  • Would like a mattress that performs very well when used with an adjustable base
  • Prefer products that have been more extensively tested by GoodBed
Bottom line not ideal icon 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)
  • Have a strong tendency to sleep hot (temperature regulation is pretty good, but not the best)
  • Tend to have difficulty changing positions during the night (though ease of repositioning is still pretty good)
  • Want a natural or organic mattress
