On a related note, I've been thinking about getting some help for my frequent back pain. I have scoliosis (I have the charts somewhere around here, taken when I was around 16 or 17, showing the odd curve of my back), but the doctor said it wouldn't need to be corrected - I would just struggle with some pain as I got older. Well, either "older" is here, or my mattress stinks, or my books are too heavy, because this pain is getting really annoying.
Which brings me to our search for a new (bigger!!) mattress! What do you sleep on? Has your mattress been passed down your family, or did you buy it yourself? If you got it yourself, what did you look for? I've seen everything from Memory Foam to Sleep Number to Posturepedic... we want to keep the costs down, but we also don't want to end up buying another mattress in a few years because we cheaped out.
Ideas?
On a side note, I am in love with this bed frame (ignore the heinous bedding!):
