Hi Nuclearmomb,
While price is certainly one part of the value of a mattress purchase … I would tend to choose a mattresses based on it’s “value” rather than on the price alone. 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).
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 “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.
The Restonic mattresses you are looking at may contain at least some polyfoam (you can check the law tag to confirm this) which could be a weak link in the mattress. If you can find out all the information listed in this article and post it on the forum then I’d be happy to make some comments about the quality and durability of the materials and the mattress “as a whole” and let you know if there are any obvious weak links in the design in terms of durability.
There isn’t a “formula” that can be used to assess or “calculate” value because there are so many different variables and criteria involved that are more or less important to different people that may be very different from someone else and because the “value” of a mattress purchase is always relative to the other finalists you are considering or to the other mattresses that are available to you in the area or online.
If you let me know your city or zip code I’d be happy to let you know about the better options or possibilities I’m aware of in your area.
The mattress shopping tutorial also includes a link to a list of the members here that sell mattresses online (in the optional online step) that compete well with the best in the industry in terms of their quality, value, service, and transparency and many of them also make latex and latex hybrid mattresses that use different types and blends of latex that have a range of different designs, options, features, return and exchange policies, and prices that that may also be well worth considering or that you can use as a reference point for “value”.
