Visually we love these, but they were difficult to get together and don't operate exactly as they should. We bought three and only one swivels well. The threaded column on the others just doesn't operate freely even without the locking piece tightened. Also, the bolts/holes did not line up, so it wasn't easy to put together. A few of the bolts can't tighten, so just hoping that the adjacent bolts stay tight. But yes they look very nice.
