Hi Cesar,
Thanks for activating this thread and pointing out to the changed lineups. I 've updated the memory foam listings in post #12 here and removed a few links in previous posts pointing to discontinued or modified lines. I did not check up on the non-members entries yet but will have another sweep through sometime soon as time permits.
It is quite difficult to maintain and keep up to date records and listings of retailer/manufacturers in across the country in an ever-changing landscape of the mattress industry but as we come across new information we revisit and edit the old listings to add/remove any relevant information. 
but feel free to point out if there is something that escaped my attention in this thread.
