Hi Walden710,
There is more about the 3 most important parts of the “value” of a mattress purchase in post #13 here which can help you make more meaningful quality/value comparisons between mattresses in terms of suitability (how well you will sleep), durability (how long you will sleep well), and the overall value of a mattress compared to your other finalists based on suitability, durability, and all the other parts of your personal value equation that are most important to you (including the price of course and the options you have available after a purchase if your choice doesn’t turn out as well as you hoped for).
The 5" of foam around the pocket coils would be polyfoam not latex and the specs they gave you would be for the latex comfort layer.
They don’t mention the density of the polyfoam encasement around the pocket coils and if you sit on the edge of your mattress or sleep with most of your weight concentrated on the outside edge of the mattress on a regular basis it would be a good idea to make sure that the foam density was at least 1.8 lbs.
Other than that … there are no lower quality materials or weak links in the mattress that would be a cause for concern in terms of durability.
The better option or possibilities I’m aware of in and around the Milwaukee area (subject to making sure that any mattress you are considering meets the quality/value guidelines I linked earlier in this reply) are listed in post #2 here.
If you are visiting Chicago then the Chicago list is in posts #2 and #4 here.
