Really like the design! My girlfriend and I are sailors, and moving in together in san francisco - thinking of making something of this nature, and like the modular, easily moveable design.

I want to make a platform for a full mattress with the possibility of adding a canopy. Seeing as we are students and have the finances (or lack thereof) to prove it, we want to save money (thinking 200-300 dollar range) and we were going to construct the bed out of old sailboat masts (usually extruded aluminum, but not always circular)

To hold up the mattress, I was thinking of using webbing/rope to create a sort of net for the mattress (no box spring) to rest on. I want to be able to take it apart and put it in the back of a car easily, and welding seems like it will be out of the question - wondering if lashing some of the joints would be possible...
