Hi Bsmitty,
There are some comments about sizing variances in post #2 here.
It’s not unusual that a compressed mattress can take up to 72 hours to regain it’s full size so I would wait a little longer but if you have followed the suggestions in the post I linked and if for some reason your mattress is still out of spec then I would call Mario at Brooklyn Bedding (either at their main number 888.210.8751 or his number 480.323.8831) to let him know and he will be happy to help you.
