Our Take on IntelliQube Signature IQ
Michael Magnuson
Founder of GoodBed, Leading Mattress Expert
BEST if you
- Want a medium-soft mattress (i.e., just a little softer than average)
- Are either a side or back sleeper
- Are seeking a mattress with excellent materials and construction
- Often sit or sleep along the edge of your bed (edge support is very good)
- Are easily disturbed by other movements in the bed (motion isolation is excellent)
- Want a mattress that helps you stay cool while you sleep
- Prefer an above average amount of 'memory feel'
- Enjoy sleeping just a bit more 'in' your mattress than 'on' it
NOT IDEAL if you
- Are a stomach sleeper, especially if you weigh more than 250 lb
- Tend to have difficulty changing positions during the night (though ease of repositioning is still pretty good)
- Want a natural or organic mattress
