GoodBed Expert Review
Our Take on Serta iComfortECO Smooth Hybrid S50UHD Medium

Founder of GoodBed, Leading Mattress Expert
- Want a mattress with a medium amount of softness
- Are either a back or side sleeper, especially if you weigh 200 lb or less
- Prefer an 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
- Like a little bounce in your mattress, but not much
- Are a stomach sleeper, especially if you weigh more than 250 lb
- 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
- Want a natural or organic mattress (though this mattress is still pretty good in terms of avoiding harmful chemicals)
