Hi mboychuck,
I would suggest “resetting” how you look for a mattress and start with the tutorial post here which has all the basic information, steps, and guidelines that can help you make the best possible choices … and learn how and why to avoid the worst ones (including major brands like Sealy or any other manufacturers that don’t disclose the quality of the materials in their mattresses).
Once you get to step 3 … then some of the better options or possibilities I’m aware of in the Greater Toronto area are listed in post #1 here.
