Jahof Adjustable Table Legs 22-36 inch (55-90cm), Metal Desk Legs Ø42/38 mm with Screws, Telescopic Legs for Tabletops, DIY Desk, RV, Home and Office (4pcs, Black)

Not cheap, but impeccable construction. And bolt-on construction means that you can adapt to your needs over time. I build a small table for a very specific application and these legs are a bit much. However, I plan to build a table top and swap these legs over to that.

Exactly as described, came quick and packaged nicely without damage. We’ll built and strong but simple and functional. Highly recommend.
