2.5 vs 3.5"

Comparing the two thicknesses, I found the 3.5" mattress considerably more comfortable and worth the additional weight. Of course, it's not "really" 3.5" thick. But I could feel my hip bones on the ground with the 2.5" but not with the 3.5".
25" is a good width. 20" is too narrow to support your arms and shoulders. 30" may be overkill, so 25" is a happy medium.
