This diminutive Odoru Table Circle is designed for camping. It folds flat and is easy to assemble, relying on tensegrity.

The material is (obviously) OSB, and the legs are (surprisingly) stainless steel. I’d have guessed aluminum.

The table diameter is 240mm (9.4″).

These are in production by Japanese camping gear manufacturer Fukasaku Base, and run ¥6,750 (USD $43).
