How can I build a platform bed?

Answer 1

You can be as elementary as cinderblocks with 3/4 inch plywood over the top. But I suspect you'll want something nicer, look at this web site:

Along with stone, mud and animal parts, wood was one of the first materials worked by early humans. Microwear analysis of the Mousterian stone tools used by the Neanderthals show that many were used to work wood. The development of civilization was closely tied to the development of increasingly greater degrees of skill in working these materials.
