Hi timberghost,
Not much different from most other weeks … long hours, lots of research, and many interesting posts on the forum to reply to … except the week included my birthday so of course I also had a few “happy birthday” phone calls from people or family I don’t talk with as often
Most of their mattresses use 3 lb memory foam so I would confirm this if you did go in this direction (see here).
This clearly sounds to me like your mattress is too firm (which probably means it has a fairly thin layer of lower density memory foam over a firmer polyfoam support core). Since you need some extra softness and pressure relief … the topper guidelines here and the posts it links to may help you choose the most suitable thickness. In general … it’s usually best to choose 'just enough" extra softness so that you don’t end up with comfort layers that are too thick and soft and replace a pressure relief issue with an alignment issue.
