Hi 8grands,
The “value” of a mattress purchase depends on the size of the mattress, what is included in the purchase (foundation, any other “bonuses” etc), and most of all how it compares to the other “finalists” you are considering or other mattresses that are available in your area (or online of you are including online options in your research) based on all the parts of your personal value equation that are most important you.
In other words there isn’t a “formula” that can tell you whether the price of a mattress is “reasonable” or not based only on the materials inside the mattress without taking all the other factors that are part of the “value” of a mattress purchase into account as well. There is more about the three most important parts of the “value” of a mattress purchase in post #13 here that can help you make more meaningful comparisons between mattresses and help you decide whether a mattress is a “reasonable value” for you (regardless of whether the same mattress would be reasonable for someone else that had different criteria or was in a different area and had a different range of mattresses available to them)…
Having said that … Golden mattresses do tend to sell in more reasonable budget ranges and are often better “value” than many other manufacturers that use similar materials.
