Hi GenericMattressShopper,
The mattress shopping tutorial includes this link to a list of the members here that sell mattresses online and 4 of them make 3 x 3" latex mattresses that have the option for two 3" layers of 100% natural Dunlop (or organic Dunlop) in the bottom two layers, 100% natural or blended Talalay in the top layer, and that have a cotton cover quilted with wool that are all under $2000 in queen (less any members discount you may be entitled to) and would be well worth talking to.
There are several others that would make “similar” latex mattresses but that don’t have three individual 3" layers that would also be worth considering.
Spindle also has a 3 x 3" latex mattress with a wool quilted cover (as you know) but they use 100% natural Continuous pour pour Dunlop (which comes in similar firmness levels to Talalay latex) and even though they are zoned … the zoning is relatively mild and they may also be well worth talking to about whether the zoning would affect you adversely (which I would doubt).
Testing a mattress in person or sleeping on it is the only way to know for certain whether a mattress is a good match for you in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences) but when you can’t test a mattress in person then the most reliable source of guidance is always a more detailed conversation with a knowledgeable and experienced retailer or manufacturer who can help “talk you through” the specific options they have available based on the information you provide them, any local testing you have done (assuming you know the firmness of all the layers in the mattresses you have tested which may not always be possible to find out), and the “averages” of other customers that are similar to you (see mattress firmness/comfort levels in post #2 here). They will know more about “matching” their specific mattress designs to different body types, sleeping positions, and preferences than anyone else.
There is also more about the different ways to choose a mattress (either locally or online) and how to identify and minimize the risks involved with each of them in post #2 here.
