Hi Gazel,
Congratulations on your new mattress … and thanks for the update 
As you know there will certainly be a break in and adjustment period for any new mattress as the foams lose any of their “false firmness” and the cover loses any of its initial stiffness and your body gets used to a new sleeping surface that is different from what you were sleeping on (see post #3 here). There are also some suggestions in post #2 here that may be helpful as well.
I’m looking forward to any updates you have the chance to share once you have had the chance to sleep on it for a few weeks.
