Hi rsvoir,
This is a great list to use to build your “personal value equation”. The only remaining step would be a more in depth conversation so that they they can help you “rate” the mattresses you are considering based on your criteria so you can make the best decision for you. They would know how each of their mattresses “rated” for each of your criteria better than anyone.
The only one I would add (but this probably goes without saying) is suitability for your body type and sleeping positions in terms of PPP.
