GoodBed Expert Review
Our Take on Qube CoreQube
Michael Magnuson
Founder of GoodBed, Leading Mattress Expert
BEST if you
- Want a mattress with a medium amount of softness
- Are either a side or back sleeper, especially if you weigh 200 lb or less
- Are easily disturbed by other movements in the bed (motion isolation is excellent)
- Prefer an above average amount of 'memory feel'
- Enjoy being hugged or cradled by your mattress
- Would like a mattress that performs very well when used with an adjustable base
NOT IDEAL if you
- Are a stomach sleeper, especially if you weigh more than 250 lb
- Like your mattress to have some bounce
- Have a strong tendency to sleep hot (temperature regulation is OK, but not the best)
- Regularly sit or sleep along the edge of your bed (edge support is good, but not the best)
- Tend to have difficulty changing positions during the night (though ease of repositioning is still pretty good)

Yes, the Qube CoreQube mattress is adjustable base compatible. This means it is designed to be used on an adjustable base without incurring damage or voiding the warranty. In our review of this mattress, we tested it on an adjustable base to look for any adverse effects as the head and foot are elevated, and to see how well it conforms to the contours of the base both with and without the weight of a sleeper. Overall, we found the CoreQube to have very good adjustable base compatibility.
