When the working-from-home boom started, most people set up at the kitchen table, hunched over a laptop, with no real expectation it would last. Five years later, plenty of us are still working from that same kitchen table, and our backs, necks, and shoulders are paying the price.
Home office ergonomics isn't about buying expensive gear. The most impactful changes you can make cost between $0 and $200 total, and they'll save you thousands in physio bills and time off work over the next decade.
The 5 things that matter most
- Get your monitor at eye level.
- Use an external keyboard and mouse if you're on a laptop.
- Sit on a chair with adjustable height and lower back support.
- Set up your lighting properly.
- Take a 30-second standing break every 30 minutes.
That's the whole game.
Fix 1: Monitor height
The single most important ergonomic principle: the top of your monitor should be at or just below eye level when you're sitting upright in your chair.
Why this matters: every centimetre your monitor is below eye level pulls your head forward and down. A head tilted forward 30 degrees places about 18kg of effective load on the muscles at the back of your neck.
If you use a laptop: the screen and the keyboard cannot be at the right height at the same time. The only way to fix this is a laptop stand or external monitor. A $30 laptop stand combined with a $40 external keyboard and $30 mouse gives you a fully ergonomic laptop setup for under $100.
Fix 2: Keyboard and mouse
Your forearms should be roughly parallel to the floor when you type. Your wrists should be in a neutral position, not bent up, not bent down, not bent sideways.
Quick fixes:
- Pull the keyboard close to you. Most people put the keyboard too far forward.
- Lower your chair if your forearms angle up to the keys.
- A separate ergonomic mouse is significantly better for the wrist than the trackpad on a laptop.
- Vertical mice are excellent for people who already have wrist or forearm pain.
Fix 3: Chair
You don't need a $1,500 Herman Miller. You need a chair that ticks five boxes:
- Height adjustable
- Has a proper backrest with lower-back support
- Armrests that adjust (or no armrests at all)
- Seat depth that fits your legs
- Casters and stable base
A decent chair is available in Australia for $200 to $400. If you can't afford that, the cheapest meaningful upgrade is a lumbar support cushion plus a seat cushion.
If you're already in pain, a lower back support brace worn for the first half of the day can give you the lumbar support you'd otherwise be relying on the chair for.
Fix 4: Lighting
Lighting is the most underrated ergonomic factor in home offices.
- Natural light is best. Position your desk perpendicular to a window.
- Avoid direct overhead lighting behind the monitor.
- Add a desk lamp that lights your work surface, not your screen.
- 20-20-20 rule for eye strain: every 20 minutes, look at something 20 feet away for 20 seconds.
Fix 5: The 30-30 rule
Sitting damages your spine in proportion to how unbroken the sitting is. The fix is interrupting the sitting.
The rule: every 30 minutes of sitting, stand up for 30 seconds.
Set a recurring timer on your phone or use a free app. Most people can't do this consistently without a reminder for the first month, that's normal.
What about standing desks?
Standing desks are useful but oversold. Standing for 8 hours a day causes back, hip, knee, and foot pain. The right approach is alternating, 30 minutes sitting, 15 minutes standing.
Common home office mistakes
- Working from the sofa. Worst posture position you can choose.
- Working from bed. Second worst.
- No defined work area.
- No water bottle on the desk.
