GoodBed Expert Review
Our Take on Beautyrest Harmony Lux Diamond Plush

Founder of GoodBed
Michael Magnuson

Founder of GoodBed, Leading Mattress Expert

Bottom Line - Here was our assessment of this product.
Bottom line best icon BEST if you
  • Want a mattress with a medium amount of softness
  • Are mainly a back sleeper (though this mattress can also be very good for stomach sleepers)
  • 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)
  • Prefer a slightly above average amount of 'memory feel'
  • Enjoy sleeping just a bit more 'in' your mattress than 'on' it
Bottom line not ideal icon NOT IDEAL if you
  • Weigh 225 lb or more, especially if you sleep on your stomach
  • Have a strong tendency to sleep hot (temperature regulation is pretty good, but not the best)
  • Don't like any bounce in your mattress
  • Want a natural or organic mattress
