Hi minmin001,
As you can see in post #1 here … I don’t provide advice on specific mattresses to buy … only how to make the best possible choices that fit your personal criteria. This post is the most important post on the forum and will provide you with the information, steps, and guidelines that can help you make the best possible choices.
The knowledge, experience, and guidance of who you deal with can be as big a part of the value of a mattress purchase as the mattress you buy.
You have much higher odds of being able to tell the suitability of a mattress with careful and objective personal testing. You can tell the quality and value of a mattress by comparing the materials and design to other similar mattresses. The “missing link” is the retailer and manufacturer you are dealing with and their willingness to provide you with the information you need about their mattresses and designs along the lines of this article and of course their knowledge and experience that can provide you with the help and guidance and education that can help you make better and more informed choices.
Some of the better options and possibilities in the Austin area I’m aware of are listed in post #2 here.
