Check out http://www.freeww.com/beds.html . There is a child's platform
bed, but you could always size it for King size. If you are going to paint
it, get poplar, soft maple or alder. If you are going to stain it, get
whatever looks good to you and you can afford.
Go to your library and pick up "Beds" by Jeff Miller. It has a queen size
platform bed in it with the math you need to make it into a king. If the
library doesn't have it, it is a Tauton press book so you can probably order
it from their website.
