Hi CodeWzrd,
The mattress shopping tutorial includes this link to a list of the members here that sell mattresses online (in the optional online step) and many of them sell latex and latex hybrid mattresses that use different types and blends of latex that have a wide range of different designs (including component latex mattress kits), options, features, return and exchange policies, and prices that would be well worth considering.
Post #3 here also includes a list of many of the online manufacturers that sell component latex mattress kits as well (with some overlap with the members list).
