Hello my mattress buying friend!
I searched and found the best place for advice is on:
http://www.philly.com/mld/philly/liv...=list&pageNo=9
You can search the posted questions to see if your mattress has been asked about. You can ask questions and the "host" will answer you quickly (if he has not recently addressed the same question).
I learned more reading this site than anything else. The guy who gives advice also sells mattresses, but I found exactly what I wanted at a local store. Depending upon where you live, shipping is free (from that guy).
Good luck! Mattress buying was a lot more complicated than I had imagined. The bastard mattress making companies change the names all the time so it becomes very difficult to compare apples to apples. Ask the expert and he will answer your questions! And, he is good!
