Hi Nightraptor,
My reply would be the same as my reply in post #2 here.
If you are interested in local options either to do some local testing as a reference point to find out which types of materials or mattresses you tend to prefer or for an actual purchase then if you let me know your city or zip code I’d be happy to let you know about the better options or possibilities I’m aware of in your area.
If you are also considering online options then the mattress shopping tutorial includes several links to lists of many of the better online options I’m aware of (in the optional online step) that include many different types and categories of mattresses that use different materials and components in a wide range of designs, budgets, firmness levels, and with different return/exchange policies that may be well worth considering as well (assuming that the materials and components in any mattress you are considering are durable enough for your body weight).
