Setting up a desk that does not hurt after four hours
People arrive at our showroom looking for a chair to solve a back or a neck problem, and often the chair is not the problem. A workstation is a system — chair, desk, screen, keyboard — and getting the order of adjustment wrong means fighting one part with another.
There is a correct order, and it starts at the floor.
1. The chair, from the ground up
Set the seat height so your feet are flat on the floor and your thighs are roughly parallel to it, with a slight downward slope at the knee if the chair allows.
Set the seat depth so there is a two- to three-finger gap between the front edge of the seat and the back of your knee.
Set the lumbar support so it meets the inward curve of your lower back, and sit back into it. A chair adjusted correctly and then perched on the front edge of is doing nothing.
2. The desk, relative to the chair
With the chair correct, your elbows should be at roughly the desk height, forearms level or sloping very slightly down.
If the desk is too high — which it usually is, since most fixed desks are built at around 29 inches for a tall user — raise the chair and add a footrest. Do not lower the chair to reach the floor; that lifts your shoulders for the whole day and is the most common cause of neck and upper-back pain in home offices.
A footrest is the cheapest genuinely effective ergonomic purchase most people can make, and it is the one nobody buys.
If the desk is too low, raise it on risers. Working with your wrists angled up is the fast route to forearm trouble.
3. The screen
Top of the screen at or slightly below eye level, about an arm’s length away, and directly in front of you rather than off to one side.
A laptop cannot satisfy this. The screen and the keyboard are attached, so either the screen is too low or the keyboard is too high. The solution is a laptop stand plus a separate keyboard and mouse, and it costs very little compared to a chair.
For dual screens: if you use both equally, straddle the centre line between them. If one is primary, put it directly in front and the second to the side.
4. Keyboard and mouse
Close enough that your upper arms hang at your sides rather than reaching forward. The mouse beside the keyboard at the same height — reaching over a number pad all day is a shoulder problem waiting to happen.
Keep wrists straight and floating, not resting while typing. A wrist rest is for pauses, not for use.
5. The armrests, last
Set so your shoulders are relaxed and your forearms rest lightly. Armrests set too high push shoulders up; set too low they encourage leaning. If they stop the chair going under the desk, lower them or use flip-up arms.
The things that matter more than the chair
Movement
No posture is good for eight hours. The best chair in the world held in one position all day will still cause problems. Stand up every half hour, even briefly. Change your recline angle through the day. A chair with a free-float tilt encourages this; a locked-upright chair prevents it.
Lighting
Screen glare makes people lean forward and tilt their head, and they blame the chair. Put the screen perpendicular to a window rather than facing or backing onto it, and add a task light for paperwork.
Small rooms and shared spaces
If the desk is in a bedroom or a living room, the chair is furniture for most of the day. Armless or flip-arm chairs tuck fully under a desk; a compact base takes less floor. Neither costs support if the seat height range and the lumbar adjustment are right.
A five-minute check
- Feet flat, thighs level.
- Gap behind the knees.
- Lower back supported and in contact with the backrest.
- Elbows at desk height, forearms level.
- Top of screen at eye level, an arm’s length away.
- Shoulders relaxed, wrists straight.
If all six hold, the chair is doing its job. If any fail, fix the one nearest the floor first — the others usually follow.
What we publish
Our chair listings carry the seat height range, seat depth, back height and armrest adjustment so that you can check a chair against this sequence before buying rather than after. If you want to talk it through, the South Michigan Avenue showroom is on the phone during opening hours.
Common questions
What should I adjust first?
The chair height, from the floor up — feet flat, thighs level. Then seat depth, then lumbar, then the desk relationship, then the screen, then the armrests. Adjusting out of order means fighting one setting with another.
Can I make a laptop ergonomic?
Not on its own — the screen and keyboard are attached, so one of them is always in the wrong place. A laptop stand with a separate keyboard and mouse fixes it, and costs a fraction of a chair.
Is a footrest really necessary?
If your desk is fixed at a standard height and you are not tall, almost certainly. It is the cheapest genuinely effective ergonomic purchase most people can make, and the one nobody buys.
