Hi zab,
I would make sure that you find out the complete specifications of this mattress, as there is 3" of a “transition foam” and 3" of a base foam where the information is incomplete on their web site. Also, I usually recommend a maximum of around 4" of memory foam layers, and this one uses almost 5", so it is a little over what I would normally advise.
$1099 is the current price for the queen – it’s possible they made a mistake in the size they quoted you.
Your own personal testing is your best guidance. You’ve sated all the items have different feels, so only you can determine which “feel” you prefer best.
These are all important things to consider as part of your personal value equation. Make a Pro/Con list for each item on a legal pad for each item to make it simple.
Yes, in the mattress shopping tutorial steps I’ve linked to previously, and this article here.
I’m glad you were able to try this personally, as that is a better way to determine versus any descriptors or specifications.
