I think support is the most important thing. I sold mattresses along with furniture for almost 6 years so I understand the benefits of mattress features and it's important to take note that how you initially feel after laying on a new mattress does not equate to the actual support you might need. I'm a believer that you should get the best mattress that you can afford based on whatever the price of a mattress is divided by the number of days you plan on sleeping on that thing and do you feel that number is worth quality sleep. For us $2 per night is definitely worth great quality sleep.
