T&N 5 inch didn't work out, think I'd like this better?

Thanks, Phoenix, for the helpful response and the links you passed along. I just spoke to a salesman on the phone who seemed extremely impressed with the detail of the questions I was asking, and was very thorough with me in answering them (a good sign). Based on what I read in the links, I believe the materials would count as good quality, but would love your opinion on them anyway. From the top down:

3/4" Quilt with 1.2 lb density high resilient foam (fabric is 80% cotton and 20% polyester, quilt is made from dupont fiber)
1" Gel memory foam at 4 lb density
6" of 14 gauge coil, approximately 725 coils in a queen-sized, with 3" of polyfoam edge support at 2.5 lb density
3" of polyfoam at 2.1 lb density

The guy I spoke to confirmed that all of the foam was American-made and CertiPur certified.

Also, the mattress has a 60-day trial period, but unlike T&N, it is an exchange program, not a refund (but no restocking fee).

What are your thoughts, Phoenix? Going to lie down on it tomorrow to test the PPP side of things.
