Hi kryton619,
While other people’s comments about the knowledge and service of a particular business can certainly be very helpful … I would also keep in mind that you are the only one that can feel what you feel on a mattress and I would be cautious about about using other people’s experiences or reviews on a mattress (either positive or negative) or review sites in general as a reliable source of information or guidance about how you will feel on the same mattress or how suitable or how durable a mattress may be for you and in many if not most cases they can be more misleading than helpful. A mattress that would be a perfect choice for one person or even a larger group of people may be completely unsuitable for someone else to sleep on (even if they are in a similar weight range). In other words … reviews in general won’t tell you much if anything about the suitability, quality, durability, or “value” of a mattress for any particular person (see post #13 here).
When you are making an online purchase the only way to know whether any mattress will be a good “match” for you in terms of “comfort”, firmness, and PPP (Posture and alignment, Pressure relief, and your own personal preferences) will be based on your own personal experience when you sleep on it.
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).
While I can’t speak to how any specific mattress will “feel” for someone else because this is too subjective and relative to different body types, sleeping positions, and individual preferences, sensitivities, and circumstances and you are the only one that can feel what you feel on a mattress … outside of PPP 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 see or “feel” and assessing the durability and useful life of a mattress depends on knowing the specifics of its 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 information listed here so you can compare the materials and components to the quality/durability guidelines here to make sure 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.
The Costco listing doesn’t provide all the information I would need to make any meaningful comments about the quality and durability of the materials in the mattress or the mattress “as a whole” but Springwall has told me that they would be happy to provide the specs of the materials and components in their mattresses to consumers that ask (see post #4 here). If you are comfortable with some additional legwork (Costco probably won’t know) then you can call them and find out the information you would need to know and if you post it on the forum I’d be happy to let you know if there are any lower quality materials or weak links in the mattress that would be a cause for concern.
Costco does provide some information but the additional information I would need to know that you can ask them about each of the layers includes …
5.08 cm (2 in.) NgLatex®: I would want to know the type and blend of latex in this layer (it would be either Talalay or Dunlop and would be either 100% natural or a blend of synthetic and natural rubber). This would be a good quality material.
5.08 cm (2 in.) Convergence® latex foam: It’s not clear to me whether this is a latex layer or if it’s a polyfoam layer that is designed to have some of the properties or either latex or memory foam so I would want to know the type of material in this layer (latex or polyfoam). If it’s latex then then could be a slow response latex (which has a very low resilience and a slow response like memory foam … unlike most other latex which is a high resilience and “springy” material). If it’s latex but not a slow response latex then I would want to know the type and blend of the latex. If it’s any type or blend of latex then it would be a good quality material. If it’s a high performance polyfoam that is designed to have some of the properties of memory foam or latex then I would want to know the density of the polyfoam.
17.8 cm (7 in.) firm bio foam zoned core: This is a polyfoam support core and I would want to know the density of the foam.
