Ergodox[0] provides split keyboard kits. There are some boom-style mounted monitor workstations vaguely in the vein of the NovelQuest Emperor[1] but I have yet to see one at a remotely sane price point.

I also haven't seen the monitor mounts discrete from built-in seating, though it doesn't seem outside of the realm of possibility. One could realistically place a large A-frame styled wooden structure over a La-Z-Boy chair and mount generic monitor arms onto it via clip or screw.

So, the main challenges are just carpentry and cable management.

If you don't mind going low tech you don't need the split keyboard. Just use two usb keyboards, one for each hand. You can actually get quite productive that way. I did this for a while before discovering kinesis keyboards.

The downside is that it takes up more space, but it can be quite comfortable.

Yes, I have just discovered this recently, but the right hand mouse is still too far away.

Love me my ergodox with about a for of separation between the halves. I call it Star Trek position.
