From the Logitech website:
Introducing ERGO K860, a split ergonomic keyboard designed for better posture, less strain, and more support.
You’ll type more naturally with a curved, split keyframe that improves typing posture. The sloping form reduces muscle strain on your wrists and forearms – keeping your hands and shoulders relaxed.
