Hi Brian123,
As you can read in the links in my previous reply … “unknown brands” (or at least brands that are "unknown to most people) or “off brands” are most often a better source of better quality/value mattresses than the major brands than they compete with.
As you can also read in the links in my previous reply … the most important questions to ask are about the type, quality, and durability of the materials and components in their mattresses (see this article) along with all the other criteria that are the most important parts of your personal value equation (such as their exchange/return policy).
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 the most important part of the value of a mattress purchase is durability and assuming that the materials in a mattress you are considering are durable enough for your body type and meet the guidelines here … the choice between different types and combinations of materials and components or different types of mattresses (see this article) are more of a preference and a budget choice than a “better/worse” choice.
In other words … in terms of its durability a mattress is only as good as its construction and the quality and durability of the materials inside it (which is all about how long you will sleep well) regardless of the name of the manufacturer on the label or how long the mattress has been available on the market.
