A split keyboard is one keyboard in two halves, each with its own cable or wireless link, so you place them where your hands already are instead of putting your hands where the keyboard is. We build two of them to order in Perth, Western Australia.
Those are the mechanics, not a medical claim. Whether a different posture helps you is between you and someone qualified to say.

42 keys, no number row
You want the smallest board you can still work on, and you are happy to reach numbers and symbols through a layer. Every key stays under a finger without moving your hand.
from $250

58 keys, full number row
You want the split geometry without relearning where numbers live. The number row stays where your hands already expect it, which makes the first week much easier.
from $290

> built to order in Perth
Nobody drop-ships these. The case is 3D printed here; the board is flashed, assembled and tested here, and it is packed here. The PCB comes machine-assembled — the Corne's partly, with the rest soldered here.
> your colours, not a colourway
Case, accent and keycaps are chosen per order in the configurator and printed to match, rather than picked from three stocked combinations.
> open source, all the way down
Corne and Lily58 are upstream open-hardware designs, running QMK firmware with Vial. You can remap any key in a browser, and you are not locked to our software to do it.
> hot-swap sockets
Switches pull out and push in with no soldering, so the feel of the board is a decision you can change later.
