ErgotronLX Wall Mount System with CPU Holder

I had been looking for a standing desk for a while and came across this on some internet searches. It allowed me to fit my somewhat narrow space while also enabling both a standing and sitting configuration. It's really a simple design made with quality materials. The only small downside is adjusting the fixed height requires loosening four screws vs just a quick snap and adjust. Once you have the setting you like, though, the arms quickly swing from standing to sitting height so it's not a big deal.

It works well for our needs
