Hi Redhummingbird,
You could also try sleeping on your mattress on the floor because this would rule out whether your support system was an issue. A suitable support system would be similar to the floor in terms of flatness and firmness.
I’m not sure of the specifics of all the latex layers in your mattress but it’s unlikely that all of the layers are defective so you may be able to reuse any layers that are in good condition and only replace the layer that is causing your issues but of course the key is to first identify the reason for your experience.
Both Berkeley Ergonomics and European Sleepworks make some good quality/value mattresses in a range of prices.
While price is certainly one of the more important parts of “value” … the “value” of a mattress purchase is what is most important and price is just one of many factors that can affect the “value” of a mattress purchase. There isn’t a “formula” that can be used to assess or “calculate” the value of a mattress because there are so many different variables and criteria involved that can affect the price of a mattress that can each be more or less important to some people and not to others who may have completely different criteria or definitions of “value”. The “value” of a mattress purchase is also relative to how a mattress compares to the other finalists you are considering or to other mattresses that are available to you in your area (or online if you are also considering online options). There are many reasons that a mattress that may be “good value” for one person or in one area of the country may not be good value for someone else that has very different needs and preferences or that lives in a different area.
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).
Yes … that’s normal.
I’m looking forward to finding out what you end up decidiing to do.
