All wood workers got a question

[Ozme52]

I plan to tackle my next big wood working task some time in the next year or so. What I plan to build is a canopy style bed out of red oak boards. The post will be made from 1X4X8 boards, edges cut at a 45 angle to make a box which will be the post. I plan to glue and nail them together and possilbly make blocks big enough to fit inside and nail them to sturdy the post from twisting. I don't plan on doing any heavy suspenion with the bed just tying and some ruff sex. What do you think, will it hold up or should I just build one out of steel?

You say that now... but you know you'll be tempted at some point...

Why not use actual posts and then sheathe it with the red oak boards.
