We make a seriously heavy duty bed.
Suitable for years of 'service' ;)

Materials:

For the legs 6x4 inch fence posts. The length depends on how high you want the bed off the ground.
Side supports and the middle bracing are 4x2 inch, once again length depends on mattress sizes and I think US mattresses are differently sized to UK ones.
The top is just MDF sheet.

You will also need wood screws, we used decking screws as that's what we had. Oh and some wood glue.

Tools:

Circular Saw (really dangerous, you could cut all you fingers off)
Router (also really dangerous, 300000rpm spinning blade of death)
Chisel (sharp, could slice face off)
Drill/driver (you could fall and it stab you in the eye)
Electric Plane (will quickly remove skin to the bone)

We are not professionals. We do not know how to work any of the tools in videos. According to the comments, we should have actually died making that bed.
