Hi Symtrous,
The better options or possibilities I’m aware of in the Miami area (subject to the guidelines here) are listed in post #2 here.
While the smell of a mattress can vary from batch to batch, every new Tempurpedic (and most new mattresses) will have some initial smell. This is considered to be “normal” and not a warranty issue or a “defect” so it’s very unlikely that you would qualify for a warranty exchange. Some people are more sensitive and are affected more by certain types of materials. You can reduce the chances that you would be sensitive to a particular type of material by making sure that it has a certification for harmful substances and VOC’s but even here you will sometimes find that some people are more sensitive to certain materials even if they are certified. This would be more common with memory foam which has the most chemicals, less common with polyoam, and least common of all with latex (see here and here and here). Tempurpedic is not CertiPUR certified and anecdotally they have the most complaints about their smell and sensitivities but they are also the most widely sold memory foam mattress as well so some of the frequency of complaints would be the result of the number of mattresses they sell.
I would avoid brand shopping completely (see the links at the end of my last reply) and focus on the steps in the tutorial post and the materials in a mattress rather than the name of the manufacturer on the label which has very little to do with the quality or value of a mattress.
There is more about organic certifications in post #3 here. Most people that are looking for and “organic” mattress are really looking for “safe” materials and there are many options that are “safe” that aren’t organic but if an organic certification is important to you then you would be looking for mattresses that either use organic fibers (such as wool or cotton), organic latex, or innersprings.
If you are looking for a mattress that is certified organic as a complete mattress (and doesn’t just contain organic materials and components) then the only two manufacturers that make these are Organicpedic (OMI) and Naturepedic.
