A good home office is not a shopping list. It is a workstation fitted to your body, tasks, computer, lighting, and available space. Start by adjusting what you already own: center the screen, create enough viewing distance, bring the keyboard and mouse close, support your back and feet, and remove glare. Buy equipment only when an existing item cannot be positioned comfortably.
The guidance below follows the U.S. Occupational Safety and Health Administration (OSHA) Computer Workstations eTool. OSHA stresses that there is no single correct posture or component arrangement for every person; its eTool provides recommendations and does not create new OSHA requirements.
What do I need for a home office?
Most people need a stable work surface, a display, a keyboard and pointing device, a chair that supports the back and legs, suitable lighting, and enough room to change position. The exact equipment depends on your work. A writer who uses a laptop for short sessions may need no more than a better screen position. Someone typing for hours may need a separate monitor and full-size keyboard so the display and input devices can be placed independently.
Use this order when deciding what to buy:
- Adjust the existing workstation. Move the monitor, chair, keyboard, mouse, and light before spending money.
- Identify the failed fit. Is the screen too low, the desk too shallow, the chair unable to support your feet, or the laptop forcing your wrists into an awkward position?
- Buy the smallest category that fixes that problem. A riser may solve a low screen; a monitor and external keyboard may solve a laptop arrangement; a footrest may solve a height mismatch.
- Recheck the whole setup. Raising one item changes viewing angle, reach, glare, and leg clearance.
OSHA’s purchasing guidance covers chairs, monitors, desks, input devices, document holders, task lights, foot support, keyboard trays, and sit-stand surfaces. A sit-stand desk is optional, not a requirement for an ergonomic office.

How do I set up a home office ergonomically?
Use your body as the fit check. Aim for a balanced head and neck, relaxed shoulders, elbows close to your sides, a supported lower back, straight wrists, enough room for both input devices, and feet supported on the floor or a footrest. These are practical targets rather than a rigid pose to hold all day; changing position is preferable to forcing yourself into one arrangement.
1. Clear the desk and establish reach
Leave enough depth for the monitor to sit directly in front of you and for the keyboard and mouse to remain close to your body. OSHA’s purchasing guide says the surface should provide at least 20 inches between your eyes and the monitor, plus sufficient room for the monitor, keyboard, and pointing device. Check leg clearance as well: a deep desktop is not useful if a pedestal, cable bundle, or drawer prevents you from sitting close enough.
2. Adjust the chair before fine-tuning the screen
Set the chair so your back is supported, your thighs and legs are comfortable, and your feet rest on the floor. Adjust the back or lumbar support until your lower back is supported without pushing you too far forward. Chair height must work with desk height and display position, so expect to revisit it after the other adjustments.

Pick the symptom - the matching free tool is one click away.
If the seat cannot be lowered enough for your feet to rest comfortably, use a stable footrest. If raising the chair is the only way to reach the desk while keeping your shoulders relaxed, a footrest can preserve foot support. A keyboard tray may help when the desktop is too high, provided it leaves enough room for both keyboard and mouse and does not remove needed leg clearance.
3. Position the monitor
Place the monitor directly in front of you rather than off to one side. Begin with at least 20 inches between your eyes and the screen; OSHA’s monitor guidance gives a preferred viewing distance of 20–40 inches. The practical distance depends on screen size, text size, vision, and comfort.
Set the top line of the display at or below eye level. If you must lean forward to read, increase text size or move the screen rather than bringing your head toward it. A monitor stand or riser is useful when the screen is too low, but check that the new height does not create neck strain or place the display in a brighter reflection.

4. Place the keyboard and mouse together
Put the keyboard directly in front of you, with shoulders relaxed and elbows near the body. Keep wrists in line with the forearms instead of bending them upward or sideways. The mouse should be close to the keyboard in your primary reach area; placing it far away encourages repeated shoulder and arm reaching.
Keep clear space in front of the keyboard for the hands and avoid using a desk edge that presses into the wrists. If the keyboard is on a tray, the tray must be wide and stable enough for the mouse as well. Alternative keyboard shapes and pointing devices can be appropriate, but suitability depends on the task and the user’s hand fit.
5. Control glare and task lighting
Before buying a screen filter or brighter lamp, inspect the room. Position the display at right angles to windows and other bright light sources where possible. Close blinds, diffuse daylight, or reorient the desk when reflections make text hard to see. Use an adjustable task light for paper reading or writing, directing it at the document rather than into the screen.
Overhead lighting can create veiling reflections even when the screen itself is bright. A useful test is to display a dark page and look for window or lamp shapes on it. Move the screen or shade the light first; add a lamp only when it improves the paper task without producing a new reflection.
Do I need a separate keyboard and monitor for my laptop?
Not always. You need separate equipment when the laptop’s built-in screen and keyboard cannot both be placed comfortably for the work you do. Raising the laptop screen to a suitable height usually raises its keyboard too high for neutral wrists. Keeping the keyboard at a comfortable height usually leaves the screen too low.

- High-Resilience Molded Foam Seat – Won’t Flatten After 1 Year – Instead of budget foam that hardens and sags within months, the seat is built with high-density, high-resilience molded foam that bounces back day after day. It maintains its shape and cushioning far longer, preventing the “bottoming out” discomfort common at this price point
- Adjustable Lumbar, Not a Fixed Afterthought – Unlike flimsy plastic supports that crack or lose tension, this chair features a durable lumbar mechanism that adjusts depth to match your spine’s natural curve. Genuinely relieves lower back pressure during long sitting sessions
- Breathable Mesh Backrest – No Peeling, No Heat Buildup – Say goodbye to flaking faux leather. The high-tension mesh back promotes continuous airflow, keeping you cool in warm environments and eliminating the mess of peeling upholstery. Mesh holds up significantly better over time and looks professional years later
- Anti-Sink BIFMA Certified Gas Cylinder – A common failure in budget chairs: the pneumatic cylinder loses pressure and slowly sinks during use. Our Class 3 BIFMA-certified gas lift is built to hold its height reliably, so your chair stays exactly where you set it—year after year. No more sudden drops or mid-work adjustments
- Heavy-Duty Metal Core Base (330 lbs Capacity) – Thin plastic bases can crack under stress, especially near the cylinder hub. We use a reinforced nylon base with a metal core, providing the durability and peace of mind you need. Smooth-rolling, 360° silent casters glide across hardwood, tile, or carpet without scratching or catching
Laptop arrangement checklist
- Use a separate monitor when the built-in screen is too small, too low, or impossible to center at a comfortable distance.
- Use an external keyboard and mouse when raising the laptop would lift the keyboard above a relaxed elbow and wrist position.
- Keep the laptop stable and leave ventilation openings unobstructed.
- Place the external keyboard and mouse together in the primary reach area, not at opposite sides of the desk.
Which home-office tools earn a place?
Choose a category only when it solves a specific positioning or task problem. The comparison below uses the criteria in OSHA’s purchasing guide and workstation eTool.
| Item | When it earns a place | Compare on |
|---|---|---|
| Adjustable office chair | Your current chair cannot support your back and feet while you reach the keyboard comfortably. | Height range, seat depth, back and lumbar adjustment, armrest fit, stability, floor-appropriate casters, return or trial option, and fit for your body dimensions. |
| Monitor | The laptop screen is too small or cannot be positioned at a comfortable height and distance for the task. | Readability, height and tilt adjustment, available desk depth, centered placement, and glare control. |
| Monitor stand or riser | The display is too low and needs elevation. | Stable fit, height, screen angle, and whether the new elevation causes neck strain or glare. |
| External keyboard and mouse | Intensive laptop use makes the built-in screen and keyboard impossible to position independently. | Keyboard size and layout, hand fit, placement flexibility, mouse reach, and personal preference. |
| Desk or height-adjustable surface | The existing surface lacks monitor depth, input-device space, leg clearance, or useful height adjustment. | Surface depth and width, leg clearance, keyboard height, stability, matte finish, and adjustment range. |
| Task light | Paper work is hard to see or room lighting creates contrast problems. | Adjustable position and intensity, useful coverage, diffusion or shading, and freedom from screen reflections. |
| Footrest or keyboard tray | Chair and desk heights cannot support both your feet and neutral input-device posture. | Stable support, adjustability, leg clearance, and enough tray room for keyboard and mouse. |
Try a chair for fit where possible. Generic dimensions do not suit every body type, and a chair that looks adjustable may still lack the seat depth, back support, or armrest position you need. No item in this list is automatically the best choice for every worker.
What is the best desk setup for working from home?
The best setup is the one that lets your equipment and body share the same working geometry. Keep the display centered, the keyboard and mouse close, the back supported, the feet supported, and the light controlled. A large desk is not automatically better if it encourages the monitor to sit too far away or leaves the mouse outside a relaxed reach.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Repair Windows errors before they cause bigger problems3Fix the driver behind crashes, sound loss and screen glitchesSmall desk or shared table
Prioritize depth for the monitor and a clear area for keyboard and mouse. Remove decorative items from the primary reach zone. If the table is too high, a keyboard tray or footrest may correct the mismatch; if it is too shallow, a larger display can make the viewing-distance problem worse, so solve the surface limitation first.
Corner or side-positioned workstation
Turn your chair and display so the screen is directly in front of you during the main task. Avoid spending hours with your neck rotated toward a side monitor. Secondary screens can sit beside the primary display, but the screen used most should receive the centered position.
Shared household workstation
Mark adjustable settings or take a quick photo of the preferred chair, monitor, and keyboard positions. Each user should reset the workstation for their own body rather than accepting another person’s height or reach.

How to maintain the workstation after setup
Ergonomic fit changes when you change software, work hours, furniture, or vision needs. Reassess after moving the desk, adding a monitor, switching from a laptop to a desktop, or noticing that you lean toward the screen.

- Is the primary display still centered and at least 20 inches away?
- Is the top line at or below eye level, and can you read without leaning?
- Are shoulders relaxed, elbows near the body, and wrists aligned with the forearms?
- Are the mouse and keyboard still close enough to avoid reaching?
- Are feet supported and the lower back in contact with the chair’s support?
- Are windows, lamps, or overhead fixtures producing new reflections?
When discomfort appears
Stop treating discomfort as proof that you need a new product. First change one variable: chair height, back support, monitor distance, text size, keyboard position, mouse reach, or lighting. Work out which change helps, then recheck the rest of the arrangement. Persistent or worsening symptoms warrant advice from an appropriately qualified health professional; a general workstation guide is not an individualized medical or ergonomic assessment.
Keep cables and accessories from undoing the fit
Route cables so they do not force the keyboard or mouse into a narrow area. Keep frequently used items within the primary reach zone and move rarely used equipment elsewhere. A clear work surface makes it easier to preserve neutral positioning after cleaning or rearranging the room.
Common setup mistakes and fixes
Monitor too low
Symptom: You bend your neck or hunch toward the screen. Fix: Raise the display with a stable stand or riser, then verify distance, top-edge height, and glare again.
Monitor too far away
Symptom: You lean forward or squint. Fix: Move it within the preferred 20–40-inch range when desk depth permits, and enlarge text rather than narrowing your posture.
Chair raised without foot support
Symptom: Feet dangle or pressure builds under the thighs. Fix: Lower the chair if possible; otherwise add a stable footrest and confirm that the keyboard remains at a comfortable height.

What OSHA’s guidance does—and does not—say
OSHA’s Computer Workstations eTool describes design goals, adjustment methods, and a purchasing checklist. It explicitly says that no single “correct” posture or component arrangement fits everyone. Its pages provide recommendations rather than creating new OSHA requirements, and they are not a substitute for an individualized assessment.
Use the guidance as a decision framework: fit the person, coordinate the chair, desk, display, and input devices, control glare, and reassess after changes. That approach is more reliable than buying a fixed package of accessories and hoping it suits every task or body.
