I have had two side-by-side frigs. The first one was too narrow buy I really like the second one because it is wider. As far as the mattress goes, about three years ago I purchased a Sealy and just love it. I believe the one I purchased was a semi-hard, was not so sure that I had made the right decision after I got it, but after a couple of months I was happy with it. Guess I had broken it in.
