Hi Chrissy500,
The Simplified Choice Thread is by no means a complete compendium for what you’re trying to find. Did you look through the post I linked to in my earlier reply about online companies for Canadians?
Unfortunately, I can’t predict your husband’s reaction to the microclimate of a new mattress beyond the general information I’ve already provided or to which I’ve linked. If yo like, you can go back and reference my comments in this thread about temperature regulation in post #2.
As I think you already discovered in the comments section of the Simplified Choice Thread about the Bear mattress:
Slight caution for higher weight ranges…There are no lower quality materials or weak links in the mattress but with the foam density of the base layer [1.8 lb] I would also add a “slight” caution for those that are in higher weight ranges.
As an addition to the guidelines in the mattress shopping tutorial I linked to earlier, post #3 here has more information and suggestions about heavier weights that is worth reading.
