So we had a icomfort mattress (4.5) years old  before selecting this luxurious king mattress.  It comes in one box easy to handle.  We literally FELL into Heaven with this mattress. We can’t get our two year old out of the bed.  It’s amazing how there’s no sleep interruption when moving from side to side and the most AMAZING thing is my husband finally didn’t snore last night.  For that alone the mattress is worth it’s weight in gold, platinum and silver.
