Key Facts
Back pain from desk work is usually a setup problem, not a body problem. Five specific adjustments — none expensive — address the mechanics that cause it.
Monitor height comes first because it drives neck posture. The top of the screen should sit at eye level, letting your gaze drop slightly to the center. Too low — the laptop default — flexes your neck forward for hours; every inch of forward head tilt adds load on the cervical spine. A laptop stand plus external keyboard, or a monitor arm, fixes this in minutes.
Chair height follows: feet flat on the floor, knees at roughly 90 degrees, thighs parallel to the ground. If your feet dangle, a foot rest closes the gap. Seat height wrong by even a couple inches shifts pressure to the backs of the thighs and the lower spine. Adjust seat depth too — two to three fingers of space between the seat edge and the back of your knees.
Keyboard and mouse position determines wrist posture: wrists straight, elbows at 90 degrees, forearms parallel to the floor. Keyboard trays or a lower desk position beat raised surfaces. If your wrists bend upward while typing, that angle is compressing the carpal tunnel with every keystroke.
A foot rest improves circulation even with correct chair height — slight elevation reduces pressure behind the knees during long sessions.
Finally, movement beats any static position. No posture survives four hours unchanged; standing up every 30 minutes — even briefly — restores circulation and resets posture. Timer apps and standing desk presets make the habit stick. The combination of correct geometry and regular movement prevents the cumulative strain that no chair, however expensive, can offset alone.
