Hi Slav007,
The first suggestion I would have is to make sure you have read post #1 here and the information it links to. This will give you all the basic information you will need to make some great choices. Perhaps even more importantly it will help you exclude most of the worst choices and help you know how to identify the better retailers and manufacturers who have the knowledge and experience to help you make good choices and will put your own interests above their own. Since a mattress is only as good as the construction and materials in it … the first and one of the most reliable sign of these is when they are willing and able to tell you and educate you about the details of every layer in a mattress they sell. if you ask this about the Sealy Optimum you will quickly find out that they have little idea of the quality or value of what they are selling.
The list of some of the better options and possibilities that is closest to you is centered in the Atlanta area and is in post #2 here. When I have the chance later tonight or perhaps tomorrow I’ll take a look in the Athens, GA area and see if anything shows up as a reasonable option or at least a possibility that is closer to you.
