Hi drugolf,
Congratulations on your new mattress first of all … you certainly made a good quality choice 
[quote]Mike at Leisure will change out the bed to anything that works for us, but I want to make sure to try and go with the best option based on results. He has a similar model to our that uses coils in the support layer that might be a good way to add a little give to the support where needed? We also still have our old memory foam topper that we could throw on for a couple nights to see what happens to gather more data so to speak.
Thanks for all the advice and things to think about. [/quote]
IMO it’s much too soon to even begin thinking about making any changes to your mattress. A new mattress will break in over the first few weeks and you will also go through a period of adjustment to any new sleeping surface so I would tend to wait a month or so (or a minimum of 2 weeks) before thinking about any changes.
Post #2 here and post #2 here also have more information about the break in and adjustment period for a new mattress and also have some “non mattress” suggestions that may be helpful as well.
If you begin to think about making changes too quickly it can become overwhelming because your experience will change as well so you will have a moving target and the best suggestion (outside of the non mattress suggestions) in the first few weeks is normally to do nothing at all.

How would this bed compare with the one we purchased?[/quote]
There is more about the different ways to compare one mattress to another in post #9 here but there are too many differences between them in terms of their design and materials (and not enough specific information about the second mattress) to be able to predict or even guess at how they would compare in terms of PPP or “feel” for any specific person outside of your own personal testing or experience (or of course any insights from the manufacturer who would have personal experience with both mattresses and would know much more than anyone else about how they compare).
