Hi llvss7,
Thanks for the heads up. I’ve added them to the Portsmouth, NH list here 
I would give things a few weeks to give the mattress time to break in and for you to adjust to a new sleeping surface as well. When you have a new mattress it’s usually a good idea to “do nothing” for the first few weeks but post #2 here also has some suggestions that may be helpful.
None of these have any obvious weak links except 2" of 3 lb memory foam may be on the “risky” side in terms of durability. It’s not so thick that it would be way “over the line” but I would be very cautious before choosing a mattress with 3 lb memory foam where the thickness of the memory foam layer in combination with any other polyfoam comfort layers that were less than 1.8 lbs were 2" or more.
In terms of quality it would be well worth considering because there are no weak links in the design but only you can feel what you feel on a mattress so I can’t speak to whether it would be a good match for you in terms of PPP (see mattress firmness/comfort levels in post #2 here).
This is typically done to have two different spring rates in the mattress so that one can “help” the softness and pressure relief of the comfort layers and one can be more for support/alignment and to “stop” the heavier parts of the body from sinking down too far once the softer coils are compressed. Coil systems like this can also be different heights where the softer coils are taller than the firmer coils (you can see an example here) so that there is some initial softer compression and then the firmer coils “kick in”. It wouldn’t tend to feel lumpy because the layers above it will even out any of the feel of the coils themselves but again your own personal testing will be the best way to assess how it feels with the specific layers that are used above the coils.
