What desk height suits an average UK adult?

73 to 75cm from floor to desk surface fits adults 170 to 185cm tall with feet flat on the floor and elbows at 90 degrees. Below 1.65m height, drop to 70cm. Standing desk users want a separate 105 to 115cm height for the standing phase.

Standing or sitting desk: which is better for back pain?

Neither pose is best held all day; alternating every 30 to 60 minutes beats either extreme. A height-adjustable desk that drops in 30 seconds gets used. A chunky manual one with a hand-crank typically gets fixed at one height and forgotten.

How often should I replace an office chair?

A quality ergonomic chair (Herman Miller Aeron, Steelcase Leap, Humanscale Freedom) lasts 12 to 15 years of full-time use, often longer. Mid-range chairs (£200 to £500) give 5 to 8 years before the mechanism starts sagging. Budget chairs below £150 start failing on the lumbar adjuster at 18 to 24 months of daily use.

What size monitor for a home office?

24-inch at full HD or 27-inch at 1440p covers most office work. 32-inch and above runs into eyestrain at a normal desk distance of 50 to 70cm unless you sit further back. Two 24-inch monitors side by side outperform one 32-inch for spreadsheet and code work.

How do I set up an ergonomic home desk?

Top of the monitor at eye level, screen 50 to 70cm from your face, keyboard at elbow height with shoulders relaxed, feet flat on the floor (or a footrest). Lift the laptop on a stand if you only have a laptop; type on a separate keyboard underneath. Most lunchtime back-and-neck pain comes from the screen sitting too low.

What is the difference between a task chair and an executive chair?

Task chairs (mesh back, no headrest, focused on adjustability) suit 6 to 8 hours of computer work. Executive chairs (high back, padded, often leather) read more boardroom but adjust less and run hotter. For working-from-home, task chairs win on long-day comfort.
