I woke up without a sore back and hips for the first time in several months after the first night on this bed. I had tried a different adjustable bed but the number that was firm enough for my back when laying on my back was too hard for my hips when laying on my sides. I put the ReST into automatic mode and because it constantly adjusts I got the support I needed regardless how I was laying. I thought I was going to need to use the position mode, which detects and changes depending on whether you are on your back or side, but automatic is working great for me.
One thing we found was that the bed looked a little rough when made because there were depressions in it. We solved this problem by using one of the manual memory settings to inflate all cells 100% and we set the bed to that when we get up in the morning. Makes the bed all nice and flat.
