Our Take on Serta iComfortECO Quilted Hybrid Q40HD Ultra Plush Pillow Top

Founder of GoodBed, Leading Mattress Expert
- Want a medium-soft mattress (i.e., just a little softer than average)
- Are mainly a side sleeper (though this mattress can also be very good for back sleepers)
- Have a clear preference for being hugged or cradled by your mattress
- Can sometimes be disturbed by other movements in the bed (motion isolation is very good)
- Prefer a slightly 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
- 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
- Tend to have difficulty changing positions during the night (though ease of repositioning is still pretty good)
