I have been looking at mattresses at the home shows for years. I was happy with my prior mattress which was 15 years old and didn't believe I needed a new one. Every home show, I would try out the REM mattress and not want to get up. I finally broke down and got the REM, Cal King split mattress and have been in heaven ever since. I love that two people can adjust their own side of the bed to what is most comfortable for each individual.
