hi all,

my wife and i have been arduously searching for a new bed, so i've been poring over this forum for the last few days and have founds loads of great info - thanks to all for their contributions.

initially we were interested in the Simmons Black stuff - the Florence with the 2" memory foam topper - but it seemed awfully overpriced, and reading accounts of poor Simmons quality and the failings of pillowtop beds has pretty much ruled that out. there is a similar bed in the World Class line for much less (the Depere or Belmont depending on where you shop) but we are wary of pillow tops now.

we thought we liked firm beds (my wife often likes to sleep on the floor to mix things up), but we're realizing we need a little more compliance and support as we get older. so a foam top with a firm underpinning seems ideal.

this lead us to the Comfor-Pedic Natural. we really like it, and are ready to pull the trigger on it. (yes, i know i could "roll my own" foam bed for much less but that is not an option for various reasons.) my only question is about how the foam will hold up over the course of several years. i have heard Tempur-pedics hold up very well, and after a few years of typical use feel almost like new. my wife and i are both relatively small and light (under 150lbs). the composition of the Comfor-Pedic is:

3 1/2" 5.5 LB NXG Advanced Memory Foam (their supposedly proprietary "vacuum-sealed chamber" stuff)
2" 24 ILD Latex Foam
5 1/2" 30 ILD Base Foam 

do you guys think this is quality foam that should stay resilient for some time? i guess the NXG stuff is a bit of an unknown, but given the cost, we're optimistically hoping to get about 8-10 years of quality use out of it. thoughts/opinions much appreciated.

thanks,
marc
