Hi Amity,
I’m not familiar with the type or quality of the materials inside the Elements of Rest mattress and there hasn’t been any feedback on the forum about it but hopefully any of the forum members that have purchased it and see your post will share their comments and feedback about it.
I would also keep in mind that while other people’s comments about the knowledge and service of a particular business can certainly be helpful … I always suggest being very cautious about about using other people’s experiences or reviews on a mattress (either positive or negative) 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 because 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 (see post #13 here).
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 to fine tune the mattress or the exchange return options that are available to you).
Component mattresses certainly have some advantages because they allow you to “fine tune” the comfort or support of a mattress both before a purchase and after a purchase (either by rearranging layers or exchanging layers or components) and if one of the layers softens or breaks down before the others (usually one of the softer upper layers) or if your needs or preferences change over time you can just replace a single layer or component instead of replacing the whole mattress. There is also more about “finished mattresses” that have glued layers vs component mattresses with unglued layers and zip covers in post #15 here and post #2 here.
While I can’t speak to how any 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 … outside of 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 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 Elements of Rest site doesn’t list the type or quality of the materials and components in their mattresses so if you can find out the specifics of the type and quality of all the materials and foam layers in their mattress that are mentioned in the article I linked and post it on the forum I’d certainly be happy to make some comments about the quality and durability of the materials and the mattress “as a whole”.
