A desk setup that actually helps

Most desk advice is a diagram with angles on it. Ninety degrees here, ninety there, screen at eye level. It is not wrong exactly, but it puts the emphasis in the wrong place, and it sells a lot of chairs.

The single biggest factor is how long you stay still

The best posture is the next one. A position that is fine for twenty minutes becomes uncomfortable at ninety, and no amount of lumbar support changes that. Bodies are built to change position, and a desk job is mostly an exercise in not changing position.

So before you buy anything, change the thing that is free: get up. Every half hour or so, for a minute. Take calls standing. Fill the glass one glass at a time rather than bringing the jug.

If you do nothing else on this page, do that one.

Then get these three right

Screen height. The top of the screen roughly at eye level, so you are not looking down for eight hours. A laptop on a desk is always too low, and the fix is a stand plus a separate keyboard, or a stack of books plus a separate keyboard.

Elbow height. Your forearms should be about level with the desk so your shoulders are not held up. If the desk is too high and you cannot lower it, raise the chair and put something under your feet.

Mouse distance. Keep it close, next to the keyboard rather than out past a number pad. Working with your arm held away from your body all day is a common cause of shoulder and neck complaints and one of the easiest things to fix.

What matters less than the internet suggests

The exact chair, past a certain point. An adjustable chair that fits you is worth having. A very expensive chair is not obviously better than a decent one you have set up properly.

Standing desks. Useful because they let you change position, not because standing is virtuous. Standing still all day produces its own set of complaints. The value is in the switching.

Posture correctors and braces. They hold you in one position, which is the actual problem.

If your neck already hurts

Setup changes help, but they are slow. If you have had neck or shoulder pain for more than a few weeks, the setup is usually only part of it, and strength and mobility work does the rest.

Most of what we give office workers is short: a few minutes of thoracic and shoulder work, and something to build capacity in the neck so it tolerates a long day. It is not glamorous and it works better than a new chair.

If you want someone to look at how you actually sit and what actually hurts, that is a fifty minute session and you will leave with three things to do rather than twelve.
