Office ergonomics is about setting up your workstation so it fits you — reducing strain on the neck, shoulders, back, arms and wrists, and easing eye strain. But the single most important message is that no “perfect” posture protects you if you hold it all day: move and change position regularly, because “the best posture is the next posture.” A good chair, desk, keyboard and monitor setup plus regular movement together do far more than any one ideal position. This matters for Singapore’s many desk-based and work-from-home staff.

In a medical emergency, or for severe or sudden symptoms such as breathing difficulty, chest pain, fainting or stroke signs, call 995 immediately.
Persistent pain despite a good setup, or pain that worsens or limits work, sleep or daily life, needs a doctor or physiotherapist. With back pain, saddle-area numbness, bladder or bowel changes, or leg weakness are red flags — call 995 or go to A&E. Persistent hand numbness or weakness should be assessed.
Set up your chair
Adjust the seat height so your feet are flat on the floor, or on a footrest if the desk forces a higher seat, with your hips slightly higher than your knees and thighs roughly parallel to the floor. Support the lower back using the chair’s lumbar support or a small cushion or rolled towel in the small of your back, and sit back into the chair with your shoulders relaxed rather than hunched.
Desk, keyboard and mouse
Keep your elbows at about a right angle and close to the body, with forearms roughly level with the desk. Your wrists should stay neutral and straight — not bent up, down or sideways — and avoid resting them on hard edges while typing. Keep the mouse close to the keyboard so you are not reaching out to the side, and move it with the whole arm rather than just the wrist. Keep frequently used items within easy reach to avoid repeated stretching.
Position your monitor
Set the top of the screen at or just below eye level so your neck stays neutral, place it about an arm’s length away, and put it directly in front of you to avoid a sustained neck twist. Reduce glare by positioning the screen side-on to windows rather than facing or backing them, and adjust brightness and contrast to match the room lighting. These small changes prevent much of the neck and eye strain of long screen days.
Fix a laptop setup
Laptops force a compromise — the screen ends up too low or the keyboard too high — so the key fix is to raise the laptop screen to eye level on a stand or a stack of books and add an external keyboard and mouse. This lets you keep the screen at the right height while your elbows stay at a right angle and your wrists neutral. Avoid working off the bare laptop for long stretches, which is one of the commonest causes of neck and wrist strain in home setups.
Lighting and screen breaks
Use good, even lighting and minimise glare and reflections, and remember that screen use reduces how often you blink, so blink consciously. For eye strain, the widely recommended 20-20-20 rule helps: about every 20 minutes, look at something roughly 20 feet (6 metres) away for about 20 seconds. Take regular micro-breaks and change posture — standing, stretching or a short walk every 30 to 60 minutes — because movement matters more than any single position.
Standing desks and working from home
A standing desk can help by breaking up prolonged sitting, but standing all day brings its own strain on the legs and lower back, so the benefit comes from alternating sitting and standing and moving through the day; an anti-fatigue mat and supportive footwear help. Working from home need not be expensive: raise the laptop on books to eye level, add a cheap external keyboard and mouse, use a cushion or rolled towel for lumbar support and a firm dining chair rather than a sofa or bed, and use a box as a footrest if your feet do not reach the floor.
When to see a doctor
See a doctor or physiotherapist if pain persists beyond a few weeks despite a good setup, worsens, or limits your work, sleep or daily activities. With back pain, treat saddle-area numbness, loss of bladder or bowel control, or leg weakness or numbness as red flags needing 995 or A&E (possible cauda equina), and get persistent hand numbness or weakness assessed — see our carpal tunnel syndrome and work-related musculoskeletal disorders guides. Above all, remember that a good workstation is only half the answer: the other half is building movement into your day, so set a reminder to stand, stretch and change position regularly, and treat any persistent ache as a cue to review both your setup and your habits rather than something to endure. Small, consistent adjustments — raising a screen, adding a footrest, taking a two-minute walk each hour — add up to far more comfort over a working day than any single expensive piece of equipment.
