Hi yenemy,
That saves me including a link 
The options were just updated a few days ago as well.
Your own testing will give you the best information about a mattress that “feels” similar to you (this is subjective) … and of course you certainly wouldn’t want to duplicate the quality of the layers in the iComfort which tend to use some lower quality foams and components. The same or a similar “feel” (and more importantly what I call PPP or Pressure relief, Posture and alignment, and Personal preferences) using higher quality materials (that will “keep” the feel and performance for much longer) would be the goal.
The adjustable bed thread here also includes more information and some good value sources for adjustable beds as well.
