Ergo

Seated

Build the setup from the chair up. Set the seat so your thighs are level, then the keyboard to your seated elbow height, then the monitor so its top meets your seated eye line.

1. Monitor top = eye level

   At seated eye height · glance slightly down

2. Elbows 90–100°

   Keyboard at seated elbow height · shoulders relaxed

3. Knees ≈ 90°, feet flat

   Thighs level · feet flat on floor or a footrest
