Our Take on Serta iComfort Hybrid Blue Fusion 4000 Plush Pillowtop

Founder of GoodBed, Leading Mattress Expert
- Want a soft mattress
- Are mainly a side sleeper
- Have a clear preference for being hugged or cradled by your mattress
- Are easily disturbed by other movements in the bed (motion isolation is excellent)
- Prefer an above average amount of 'memory feel'
- Like a little bounce in your mattress, but not much
- Are a stomach sleeper, especially if you weigh more than 250 lb
- 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 OK, but not the best)
- Tend to have difficulty changing positions during the night (though ease of repositioning is still OK)
- Want a natural or organic mattress
