Sleep on the floor, I never had any huge back issues, but when I was younger had lower back soreness due to heavy bent over rows, anyway one night went out got wasted, and when I got home passed out on the ground, when I woke up I felt like a million bucks, no back issues at all. From that day on I sleep on the ground unless, I have a girl over, but even the matress I bought is very thin and hard Also, buy a reverse hyper machine made by Lou Simmons of Westside barbell or find a chiropractor that has machine at their practice.
