GoodBed Expert Review
Our Take on Serta iComfortECO Smooth Hybrid S30LTX Medium

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 mattress with a medium amount of softness
  • Are either a back or side sleeper, especially if you weigh 200 lb or less
  • Can sometimes be disturbed by other movements in the bed (motion isolation is very good)
  • Prefer a slightly above average amount of 'memory feel'
  • Would like a mattress that performs very well when used with an adjustable base
  • Enjoy sleeping just a bit more 'in' your mattress than 'on' it
Bottom line not ideal icon NOT IDEAL if you
  • Are a stomach sleeper, especially if you weigh more than 250 lb
  • Don't like much bounce in your mattress
  • 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)
  • Are allergic to latex
