If you want something a little more versatile than a standard pedestal that will lower for a bed, you may have to look farther away. The top in the photos was temporary to test the locking mechanism.
I purchased a pedestal from Europe. The only dealer I found willing to ship was in France. They are a rv parts company. It not only will lower, but will also slide to the side, forward/back, and rotate. The base is oval is shape.
Locked in cener positiion (handle locks the table top from sliding)
Top will slide to either side.
It will also slide forward and back. The handle on the top is the release for raising/lowering. You attach it to the bottom of your table top. I would recommend removing the cable retainer from the base and let the cable come straight out of the pedestal. The cable works easier if 'gentle' curves are used to keep it in place. The factory retainer puts a curve on the cable too close to the end of the cable.
They currently have the round pedestal on sale. If you query them, they will quote shipping costs. For me it was 38 Euros. They ship through TNT Freight, which is owned by FedEx. I received mine in about 3 weeks.
This one from Italy is similar, the lock for height is the button on the base of the pedestal. Couldn't find a European dealer to ship to the US. It is available in Australia, but they won't ship to the US.
Here's a video of the Italian pedestal.
