Hi fixmenow,
Most memory foam mattresses use the same basic types of materials with one or several layers of memory foam on top of a firmer polyfoam support core. Having said that ā¦ there is a huge range of different designs that have different firmness levels and that use either lower quality and less durable materials or higher quality and more durable materials that are in a wide range of prices (lower quality and less durable materials are less costly than higher quality and more durable materials).
There are a lot of ācheapā memory foam mattress that use low quality materials that wouldnāt be worth considering and there are also many higher quality memory foam mattresses that would make a suitable and durable choice.
There is more about the 3 most important parts of the āvalueā 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 doesnāt turn out as well as you hoped for).
While nobody can speak to how any specific mattress will āfeelā 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 ā¦ outside of PPP (which is the most important part of the āvalueā of a mattress purchase), the next 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 canāt see or āfeelā 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).
While I canāt speak to how it will feel to you ā¦ the mattress in the picture you linked uses 5 cm of 50 kg/m3 (3.1 lb/ft3) memory foam which is a lower quality and less durable material than I would consider.
There are many different formulations of memory foam that have different firmness ranges and different properties (such as slower or faster response, more or less breathable, more or less temperature sensitive etc) depending on the chemical formulation of the memory foam. There is more about the different properties that can be formulated into of different types of memory foam in post #9 here and in post #8 here. There are also hundreds if not thousands of different memory foam mattresses that have very different designs and memory foam layer thicknesses and some of them may be a good āmatchā for you in terms of PPP and some of them may be completely unsuitable for you to sleep on.
The only reliable way to know whether any mattress is a good āmatchā for you in terms of comfort, firmness, and PPP willl be based on your own careful testing (hopefully using the testing guidelines in the tutorial) or your own personal sleeping experience.
If for any reason you arenāt confident that a mattress you are considering would be a suitable choice in terms of firmness, āfeelā, or PPP then any trial period and the options you have after a purchase including the exchange/return policy (and any costs involved) would also be a more important part of the āvalueā of an online purchase just in case (and in spite of the ābest judgementā of everyone involved) the choice you make doesnāt turn out to be as suitable as you hoped for.
In its simplest form choosing the ābest possibleā mattress for any particular person really comes down to FIRST finding a few knowledgeable and transparent retailers and/or manufacturers (either locally or online) that sell the types of mattresses that you are most interested in that are in a budget range you are comfortable with and that you have confirmed will provide you with the all the information you need about the materials and components inside the mattresses they sell so you will be able to make informed choices and meaningful comparisons between mattresses and then ā¦
-
Careful testing (hopefully using the testing guidelines in the tutorial) to make sure that a mattress is a good match for you in terms of ācomfortā, firmness, and PPP ā¦ and/or that you are comfortable with the options you have available to return, exchange, or āfine tuneā the mattress and any costs involved if you canāt test a mattress in person or arenāt confident that your mattress is a suitable choice.
-
Checking to make sure that there are no lower quality materials or weak links in a mattress you are considering relative to your weight range that could compromise the durability and useful life of the mattress.
-
Comparing your finalists for āvalueā based on #1 and #2 and all the other parts of your personal value equation that are most important to you.
