My wife is 5 5 and 140. She finds the mattress med firm and sleeps on both her sides and back. She would prefer a little softer feel. 
I'm 5 11 and 190 and find the mattress med soft, sleeping on one side primarily and occasionally back. I would prefer a little more hip support.
We are both hot sleepers and find the mattress temp very comfortable. We notice very little motion transfer and getting in and out of bed is easy.
We get a good 8 hours sleep and wake up refreshed.
We would recommend this bed to a friend or relative.
