I've been doing research in person and on this site into various types of mattresses. Based on my brief, real-world tests, I really like the feeling and promise of foam mattresses. I spent a few nights on a very cheap one in a rental condo this summer and even liked the way that one felt. Now i'm looking into various options and have found the 13" Ara from Costco at around $1400 (king), which seems to represent a great value. Of the Tempurpedic models, the one I liked best is the Rhapsody which costs $3300 (mattress only, king).

I'm really struggling with the price premium for a Tempurpedic. Is it any better? If so, is *that* much better than the Costco mode, and howl? Yes, I know some of this is subjective, but there must be objective reasons to justify the price premium, or at least for me to be willing to pay it ;).

I realize this is somewhat of a recurring question, but I haven't found a direct comparison made in another thread. Thanks in advance for your help.
