Unless you have access to pipe threading for the pipe for the cast iron fittings, I would expect square section steel tube, or aluminium section would be better. Plenty of fittings for furniture construction.  Aluminium is considerably easier to work with, lighter weight, needs no surface finishing, can be cut with normal woodworking tools, etc., but pipes and cast iron fittings can give you a steam punk effect, if that is your thing.

Lots of plans for PVC on the Internet. I have a library of PVC fittings in OpenSCAD.
