Hi levipainter,
Denver Mattress would normally be one of the better quality/value options available to people where they have an outlet yes … at least if you are focusing on the line of mattresses they make and not the major brands they also carry.
Which of the specific mattresses they make however that may be a good choice for you would depend entirely on which one best matches your needs and preferences and the results of your own specific testing for PPP (Pressure relief, Posture and alignment, and Personal preferences) and your own “personal value equation”.
