Hi Crock,
DahliaM’s question is exactly what I would ask as well. The first step in making meaningful comparisons is to know the specifics of a mattresses you are considering and that you like so you can look at other mattresses with a similar design, construction, and materials and make meaningful quality and value comparisons based on your own personal value equation.
Making comparisons based on brand is not nearly as effective as making comparisons based on the specifics of a mattress.
