What is the correct desk height for a home office?

Your work surface should put the keyboard at elbow height — forearms parallel to the floor, shoulders relaxed. For most people that's 27-29 inches, while most dining tables are 29-31 inches. If your table is too tall, raise your chair and add a footrest rather than hunching your shoulders up.

What's the cheapest way to make a home office ergonomic?

Three free fixes cover most of the benefit: raise your screen to eye level on a stack of books, put a rolled towel behind your lower back at belt height, and put a box under your feet so your knees sit near 90 degrees. The single best cheap purchase is an external keyboard and mouse ($30-50) if you work on a laptop.

Is working from the couch sometimes OK?

In 25-30 minute stretches with a lap desk and your back supported, yes. The problem is duration: soft furniture offers no positioning reference points, so your spine gradually curls around the screen. Treat the couch as a break-of-scenery zone, not a workstation.

How often should I take breaks when working from home?

Posture data shows deterioration after about 30 minutes in one position, so a stand-up or position change every 30-60 minutes is the evidence-based target. Remote workers actually have an advantage here — no meeting-room decorum stopping you from standing on every call.

Do I need an expensive ergonomic chair to work from home?

No. You need height adjustability, lumbar support (a towel roll counts), and correct adjustment — in that order. A correctly adjusted $150 chair with a towel roll beats a $1,200 chair set up badly. Spend on a chair only after the free geometry fixes are done.

Is a laptop-only home office setup workable?

Not for full-time work without modification — the attached screen and keyboard guarantee either a dropped head or raised wrists. Add a $30-50 external keyboard and mouse and raise the laptop to eye level on books or a stand, and a laptop-only setup becomes ergonomically equivalent to a desktop one.

The 12-Point Checklist (Ranked by Impact)

Each item states the target and the cheapest way to hit it. The first five fix the geometry; the rest fix the habits and environment.

01
1. Screen at eye level
Top of the screen at or slightly below eye level, 20-28 inches away. This single fix addresses the most common posture failure (forward head). DIY: a stack of books under the monitor or laptop. Laptop users: see the external keyboard item — they're a package deal.
02
2. Elbow-height work surface
Your keyboard should sit where your forearms are parallel to the floor with shoulders relaxed. Most dining tables are 1-3 inches too tall. DIY: raise the chair and add a footrest (a box works) rather than lowering the table you can't lower.
03
3. External keyboard and mouse (laptop users)
A laptop can't have both its screen and keyboard in the right place. An external keyboard and mouse ($30-50) plus a raised laptop converts the worst common setup into one of the best. This is the highest-value purchase in home ergonomics.
04
4. Lower back supported
Sit back until your lower spine contacts the chair, with its natural inward curve preserved. DIY: a rolled towel or small cushion at belt height does what a $60 lumbar pillow does.
05
5. Feet flat, knees at ~90 degrees
Dangling feet pull you toward the seat edge and into a slump. DIY footrest: a ream of paper, a sturdy box, or a low stool. If your knees ride above your hips, raise the chair.
06
6. Screen directly in front of you
No sustained neck rotation. If you use two monitors, put the primary one dead center and the secondary angled beside it — not split evenly so your neck lives at 15 degrees of rotation.
07
7. Light from the side, not behind or in front
A window behind the monitor makes you squint and lean in; behind you it creates glare. Side-on natural light is ideal. Leaning toward the screen to read it is a lighting and font-size problem disguised as a posture problem — fix those first.
08
8. Frequently-used items within forearm reach
Phone, notepad, coffee: within a forearm's sweep of your keyboard. Repeated reaching to the same far spot builds one-sided shoulder strain surprisingly fast.
09
9. A real chair, adjusted — not the dining chair default
You don't need a $1,200 chair, but you need height adjustment at minimum. If the dining chair is what you have, prioritize items 4 and 5 to compensate, and treat a height-adjustable chair as your first upgrade.
10
10. Movement breaks every 30-60 minutes
The data is blunt: posture degrades measurably after 30 minutes regardless of setup quality. Stand on phone calls, refill water every hour, or use break reminders. The best posture is the next posture.
11
11. A standing option (even an improvised one)
Sit-stand alternation reduced lower back discomfort by 31.8% in workplace studies. No standing desk needed to start: a kitchen counter plus laptop stand works for calls and email blocks.
12
12. A feedback loop
Everything above decays without feedback — you adjust the chair once, but slumping returns silently. A webcam posture tracker like SitSense closes the loop by flagging drift in real time, which is how setup changes become lasting habits.

The 5-Minute Weekly Audit

Setups drift — chairs get bumped, monitors get pushed back, books get borrowed from under the laptop. Once a week, check:

Sit normally and look straight ahead: is your sightline hitting the top third of the screen?
Type a sentence: are your shoulders relaxed, not shrugged?
Glance down: are your feet flat and knees near 90 degrees?
Reach for your mouse: does your elbow stay near your side?
Check yesterday's posture data: did your scores dip at a consistent time of day? That's your break-timing problem, not your furniture problem.

The Bottom Line

Home office ergonomics isn't a shopping list — it's a geometry problem (items 1-9) plus a behavior problem (items 10-12). The geometry is fixable this afternoon with books, towels, and boxes; the behavior needs reminders and feedback because slumping is silent and gradual.

Run the checklist top to bottom once, do the 5-minute audit weekly, and let a posture tracker catch the drift between audits. That combination is what office ergonomic assessments try to approximate — and you can do it for free.

After the setup

A perfect desk still lets you slump in it.

Your setup decides what good posture is possible. It does not decide whether you hold it.
