I given up with the Sleep Number Bed. It goes tomorrow. I have a Craftmatic bed coming tomorrow. I used to have a C bed, but it was only a twin and when I moved I gave it to my friend and now I use a full size bed. But one thing that I assume is new with Craftmatic, is that each side of the mattress is a different density/firmness. I am not sure which side to start out with. But leaning in my thinking to the firmer side. Any suggestions.? Also the SN bed mattress is bolted to the frame and therefore making the bed was essentially impossible for me to make the bed and I needed help ( I live alone.) When I talked with the person from Craftmatic, he reminded me that a C bed is easier to make because when you raise both ends, you don't have to bend to put on the sheets and when you lower it, it straightens out and "makes" the bed. gailfaith
