Hi worknman,
Thanks for the update.
Based on your comments about how you are sleeping and how your “symptoms” have improved it certainly sounds like you made the most suitable choice in terms of firmness and PPP (Posture and alignment, Pressure relief, and your own Personal preferences). I would keep in mind that posture and alignment is the most important factor in how well and how deeply you will sleep followed by pressure relief followed by any other more subjective preferences you may have.
As you also mentioned there will be a break in and adjustment period for any new mattress or sleeping system as the mattress loses any of it’s initial “false firmness” and the cover stretches and loosens a little and the materials settle 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 (higher density materials like latex can take longer) and it can be surprising to many people how much their sleeping experience can change over the course of the first month or so.
I’m looking forward to any additional updates you have the chance to share.
