had to switch to side
had to switch to side sleeping and my very firm foam mattress was causing severe pressure points on my shoulders. I put a pillow under my torso to relieve the shoulder but then the pressure point expanded to the hip too. I wanted a "soft" mattress but didn't know which one. The DLX Premier has a zip off top which enables you8 to change out the high density foam if it needs adjustments or eventually wears out. This is why I bought it, flexibility to modify it. I got a medium density, and it is very plush but supportive. I am 5'11" and 225. The medium is plenty soft enough. I am very happy with the mattress. Chronic pressure points are gone. Years of suffering at night are fading. The 14" works fine on an adjustable bed, even zero gravity setting.
