Hi 1fasttvx,
That really depends on which type of latex you are looking at and your preferences and on the criteria that are most important to you for performance, “feel”, budget, or personal reasons. Post #6 here has more about the different types of latex which along with your own personal testing and experience may be helpful in deciding which type of latex you prefer.
The better options and possibilities I’m aware of in the Raleigh/Durham area are listed in post #6 here. There are certainly some good options to test and become familiar with different types of latex mattresses but where you end up buying from will depend on which of your options (either local or online) you are most comfortable with and are the best match for the parts of your personal value equation that are most important to you.
