Thanks for the information. I'm a 6'2 guy, so I'm pretty much stick with the bigger sizes and am thinking a long twin size at 25 lbs should be about right. My wife and I sleep in a California King bed and she has zero interest in partaking, so my half is about a long twin.

Actually my wife is pushing me in the idea, as I'm having sleep issues (what's new?) and she thinks it might help.

I'm anticipating spending in the ballpark of $200, at least from some brief searching I've done online.
