Hi jdeck66,
Just in case you haven’t read it yet … I would make sure you’ve read the tutorial post here which has all the basic information, steps, and guidelines you will need to help you make the best possible choices.
I think highly of Christeli and they use good quality materials and would certainly be well worth considering. A forum search on Christeli (you can just click this) will also bring up more information and feedback about them. The tutorial post also includes a list of some of the better online memory foam manufacturers and retailers I’m aware of that would also be well worth considering (it’s in post #12 here).
Once you are down to a few finalists that are all choices between “good and good”, then you can make a final choice about which mattress purchase would be best for you based on all the parts of your personal value equation that are most important to you.
