Hi Silas0220,
Welcome to the Mattress Forum! 
Congratulations on your new mattress purchase! :cheer:
Unfortunately, two nights is not nearly enough time for you to evaluate any new mattress. There will be a break in and adjustment period for any new mattress or sleeping system as the mattress loses any of its “false firmness” and the cover stretches and loosens a little and your body gets used to a sleeping surface that is different from what it is used to (see post #3 here). This would typically be a few weeks but it can be shorter or longer depending on the specifics of the person and the mattress.
I would definitely tell you to take more time adjusting to the new mattress, and hopefully as time moves on you’ll lose more of your previous “learned alignment” and the mattress will also lose more of its “false firmness”. If you unfortunately find that this product doesn’t meet your comfort needs, you did make a good choice of selecting a product that does have an available return policy.
