I use one attached to a proper adjustable desk. It just looks like an iMac floating in the air, and you can push and pull it whereever you want it to go.

Of course, look at it from behind and it's obvious it's not Apple, but it's pretty minimal.

They sent an installer. I'm sure it's possible to do it DIY, but it's not quite as simple as normal flatpack.

The cost of using a computer too much is fancy furniture and slightly less beautiful equipment. :-(
