Beds puzzle me. There are loads of different widths of bed available, but they are all the same length. I was even in a hotel recently where they gave me a triple bed (I don't know what they were expecting me to do there...) But actually, I don't mind how wide the bed is - I just want to be able to stretch out without my feet going off the end of the bed.
So why don't beds come long enough so that a reasonably tall person (and I'm only 6ft!) can stretch out? Or if they do exist, why aren't they much more common?
As far as I can tell, either there isn't the demand for longer beds, or it's a conspiracy by evil dwarves. Personally, I think the latter seems more probable.
