Has anyone tried the Ortho tempered memory foam mattress? I was at Ortho mattress today and the store is selling 9" foams for $999 and 12" for $1499, compare to Tempur pedic's rhapsody 12" at $2699. I tried looking for the review but there just isn't much info I can find on the web. I just can't tell the difference by lying on it for 5 mins with the saleperson breathing down my neck. Quite frustrated buying a mattress... please help!
