SweetNight CoolNest Hybrid 16"

GoodBed Expert Review
Our Take on SweetNight CoolNest Hybrid 16"

Founder of GoodBed
Michael Magnuson

Founder of GoodBed, Leading Mattress Expert

Bottom Line - Is the SweetNight CoolNest Hybrid 16" the right mattress for you?
Bottom line best icon BEST if you
  • Want a medium-firm mattress (i.e., just a little firmer than average)
  • Are either a back or side sleeper, especially if you weigh 200 lb or less
  • 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)
  • Enjoy sleeping just a bit more 'in' your mattress than 'on' it
  • Prefer an average amount of 'memory feel'
  • Like a little bounce in your mattress, but not much
Bottom line not ideal icon NOT IDEAL if you
  • Are a stomach sleeper, especially if you weigh more than 250 lb
  • Would like a mattress that performs well on an adjustable base
  • Have a strong tendency to sleep hot (temperature regulation is pretty good, but not the best)
  • Tend to have difficulty changing positions during the night (though ease of repositioning is still pretty good)
  • Want a natural or organic mattress (though this mattress is still OK in terms of avoiding harmful chemicals)
