Sleep number!! My husbnd and I are average sized. He wiggles and snores and gets hot. I just die but have neck and back pain and migraines. Since we got our sleep number 4 years ago it has been HEAVEN! He has his side firm, mine is softer. I don't feel him twitching and wiggling and neither one of us snores as much. It has helped my problems tremendously. And they are cheaper than temperpedic from what I've heard.
