Good point thanks you!

One reason why I was looking at foam and in particular
late was that I am supposed to tilt my bed so that my
head is 6 inches higher than my feet. I do this cause
I have gastric reflux or GERD at night.

With a conventional mattress.... since it has more mass
and is heavier... there is a tendency for everything to
"slide south" at night. G



I have a tempur-pedic adjustable bed. You can tilt the head up or the
knees up, or both. It is 9 years old and just exactly like the day I got
it. No sags, no signs of age at all. A conventional mattress will sag
over time, also they harbor mites etc. The Tempur pedic is not friendly to
mites, therefore it is less allergenic.
