Hi jqwer1,
Unfortunately the description doesn’t provide any information about the quality or durability of the foam materials inside the mattress and without knowing the quality/density of the polyfoam and memory foam in the comfort layers it’s not possible to make any meaningful comments about the durability or useful life of a mattress or identify any weak links in the design.
There is more information 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 to “fine tune” a mattress or the exchange/return options that are available to you).
While I can’t speak to how a mattress will feel or how different mattresses will compare in terms of comfort and PPP for someone else … outside of “comfort” and PPP (Posture and alignment, Pressure relief, and your Personal preferences) the most important part of the value of a mattress purchase is durability which is all about how long you will sleep well on a mattress. This is the part of your research that you can’t “feel” and assessing the durability and useful life of a mattress depends on knowing all the specifics of its design and construction and the type and quality of the materials inside it regardless of the name of the manufacturer on the label (or how a mattress feels in a showroom or when it is relatively new) so I would always make sure that you find out the information listed here so you can compare the materials and components to the quality/durability guidelines here to confirm that there are no lower quality materials or weak links in a mattress that would be a cause for concern relative to the durability and useful life of a mattress before making any purchase.
All the major brands (such as Sealy/Stearns & Foster, Simmons, and Serta) tend to use lower quality materials in their mattresses than most of their smaller competitors that will tend to soften or break down prematurely relative to the price you pay and I would avoid all of them completely along with any mattress where you aren’t able to find out the type and quality/durability of the materials inside it (see the guidelines here along with post #3 here and post #12 here and post #404 here).
The Surface Cool Plus Fiber and the 1 1/4" AirFeel Foam and the 3/4" GelTouch Foam and the 1 1/2" AirCool Gel Memory Foam in the mattress you linked are all lower quality/density materials than I would suggest considering (again no matter how a mattress feels) that would be subject to premature softening and breakdown and this would certainly be a very risky purchase at any price in terms of the durability and the useful life of the mattress.
