I need advice on a new mattress......

Hi thehause81,

The first place I would start (and probably the most important single post on the forum) is post #1 here and the information it links to. This will give you the basic information and guidelines you need to make the best possible decisions.

Once you have gathered some basic information (and I would read but not study it so that you can use it to help you identify the people who have the knowledge and experience you want to deal with) you have some very good options available in Austin. They are listed in post #2 here.
