Thanks for the input, everyone. I appreciate it.
Do you prefer any other brands?
I'm a big guy, and I detest sleep number beds. I need a firm bed and it doesn't even come close. I know people that have them that love them. Like any other bed, lay in one and try it out.
I've heard people rave about "The Heavenly Bed". It's made by Simmons and the Westin Hotels have them in their rooms. Every person I know that's slept in one loved it.
What BEG said about Tempurpedic, my wife experienced the same issue with hers and has to rotate the mattress every now and then. She really liked the Comfortpedic we got her before that one but it got uncomfortable to sleep in as fast as the Tempurpedic.
Best night's sleep I've ever gotten was on a (real) Japanese futon.
