I purchased a queen "Vilamoura" mattress Mattress Warehouse several months ago. I'm not sure what it is labeled ass at other stores (maybe lukasa/lusaka?), but it is visco firm, has a very small pillow-ish looking top and has 900-something springs. I think it "listed" at $1,500-$1,600, but I got a slightly better deal b/c I don't need a box spring (platform bed). Anyway, it felt great in the store esp. and it didn't bother my problematic back (lumbar disk issue). However, now that I'm sleeping on it, I wake and toss and turn througout the night. I'm a side sleeper and my shoulder doesn't sink in. Thus, my upper body becomes contorted. Moreover, my hip is sore from contact all night. Unfortunately, it is too late to return and I think I need to revert to a softer mattress. Lesson learned...I hope. So here's my question (and I apologize for all of the quotes!):

Does anyone have experience with the Sealy Posturepedic "Natural Origins Series?" I tested few of the series' models at Mattress Discounters. I liked it's "Cascade Creek Plush" model which has a softer top and is $1099 on sale from $1499. It's "Running Stream" model has a "luxury" plush pillow top (seemed close to its "paradise valley pillow top" model which is part of it's "reserve collection." It is $1299 on sale from $1699. Apparently the Natural Origins Series is the higher end.

Help!
