Questions on Hybrid 360 Pillowtop

  1. What is the weight of a king-sized Hybrid 360 pillowtop?
  2. Is it shipped in one piece, or is the comfort layer shipped in a separate box?
  3. Do you recommend ordering the comfort layer split even if both sides are the same firmness?
  4. If needed, can an additional 1" latex comfort layer be added inside the cover to the 3" one that comes with the mattress?
    Thanks, and all the best.
