Hi mistifa,
The first place I would start your research is the tutorial post here which has all the basic information, steps, and guidelines you will need to make the best possible choices … and avoid the worst ones.
You’ve probably seen this but the better options or possibilities I’m aware of in the Grand Junction area are listed in post #2 here although there aren’t a lot of options in the area.
While there is no way to speed up the process of good research (and a sense of urgency is perhaps one of the most common reasons for buyers remorse after a purchase) … if you are comfortable with an online purchase then the optional step of buying online may speed up the process. There is a link in the tutorial post to a list of the members here that includes many that sell latex or latex hybrid mattresses with a wide range of designs, options, customization choices, and return or exchange policies and it would be well worth browsing their sites and talking to the ones that interest you the most on the phone.
