Love the hairpin legs. Great Legs for Your DIY Table. Sources for hairpin (industrial or modern), unfinished wood (wegner danish modern), stainless steel column (contemporary), tapered (mid century modern), and tapered slim brass.
cheat sheet: Love the History behind the Detail of each style/if I ever eventually make a chair I'd love to know where each style of leg came from, what time period etc. It would make the chair all the more meaningful.
