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 either a back or stomach sleeper (though this mattress can also be good for side sleepers who prioritize firm support over extra pressure relief)
  • Often sit or sleep along the edge of your bed (edge support is very good)
  • Want a mattress that helps you stay cool while you sleep
  • Enjoy being hugged or cradled by your mattress
  • Prefer an above average amount of 'memory feel'
  • Would like a mattress that performs very well when used with an adjustable base
  • Prefer products that have been more extensively tested by GoodBed
Bottom line not ideal icon NOT IDEAL if you
  • Weigh 175 lb or less, especially if you sleep on your side
  • Don't like much bounce in your mattress
  • Want a natural or organic mattress
