Neck feeling stiff after a few hours at your desk? Are you constantly leaning forward to see your screen or reaching across the desk for your mouse?
The problem may not simply be how long you work. Your workstation may not fit the way your body needs to work.
According to the International Ergonomics Association (IEA), ergonomics, or human factors, focuses on understanding how people interact with other elements of a system and applying that knowledge to design for human well-being and system performance.
In practical terms, workplace ergonomics follows a simple idea: Fit the work to the person instead of forcing the person to fit the work.
Here are ten principles you can use to evaluate your own workspace.
What Are Ergonomic Principles?
Ergonomic principles are guidelines for designing tasks, tools, furniture, and work environments around human capabilities and limitations.
Ergonomics is broader than posture alone. The IEA recognizes physical, cognitive, and organizational ergonomics. For a desk-based workstation, however, physical factors such as posture, reach, repetition, force, movement, and workstation layout are among the most visible areas you can improve.
These ten principles provide a practical starting point.
10 Ergonomic Principles and Workplace Examples
1. Work in a Neutral Posture
A neutral posture keeps your joints and muscles in relatively comfortable positions without forcing your body to bend, twist, reach, or hold unnecessary tension.
For computer work, OSHA recommends keeping the head and neck aligned with the torso, shoulders relaxed, elbows close to the body, lower back supported, and wrists aligned with the forearms.
At your desk: adjust the chair and work surface so you can type without raising your shoulders or bending your wrists. Position the monitor so you do not continually tilt your head up or down.
For a more detailed setup guide, see PEXIO's article on correct sitting posture.
2. Reduce Excessive Force
Tasks requiring greater force generally place more demand on muscles and joints.
The ergonomic solution is not simply to “try harder.” Instead, look for ways to redesign the task so it requires less effort.
Examples: use a cart instead of carrying a heavy load by hand, improve handles and grips, or move frequently used objects to easier locations.
OSHA identifies heavy lifting, pushing, pulling, bending, awkward postures, and repetitive tasks among common work-related musculoskeletal risk factors.
3. Keep Frequently Used Items Within Easy Reach
If you repeatedly stretch across your desk for a mouse, phone, notebook, or other tool, the workspace is making your body do unnecessary work.
Keep frequently used items inside your comfortable reach zone.
At your desk: place the keyboard and mouse close to your body. Keep everyday items nearby and move less frequently used objects farther away.
The goal is not to eliminate movement, but to eliminate unnecessary reaching and twisting.
4. Work at the Right Height
There is no single perfect desk or chair height for everyone.
Your work surface should match both your body dimensions and the task you are doing. For computer work, the elbows should remain close to the body while the keyboard and mouse can be used without lifting the shoulders.
This is why adjustability matters in ergonomic furniture. A workstation that can adapt to different users is generally more useful than one fixed around a single body size.
If workstation height is one of your main concerns, explore PEXIO's ergonomic desk collection.
5. Reduce Unnecessary Repetition
Typing, clicking, handling objects, or performing the same movement over and over can increase exposure to repetitive motion.
Reducing repetition may involve changing the equipment, workstation layout, working method, or sequence of tasks.
NIOSH includes repetition, duration, force, awkward posture, and static posture among important factors when identifying ergonomic risks.
At your desk: use keyboard shortcuts where practical, position the mouse comfortably, alternate tasks when possible, and avoid unnecessary movements caused by poor workspace organization.
6. Minimize Prolonged Static Postures
A posture can look “correct” and still become uncomfortable when you hold it for hours.
This is an important point that is often missed in office ergonomics: there is no single perfect posture that you should freeze yourself into all day.
A better workstation allows you to change positions comfortably.
NIOSH recommends avoiding sitting or standing for excessively long periods and highlights the value of varying posture in office environments.
Examples: change your sitting position, stand for part of the day, walk briefly between tasks, or use an adjustable desk to create more working positions.
7. Minimize Contact Stress
Contact stress occurs when a hard edge or surface places concentrated pressure on part of your body.
At a workstation, this may happen when the edge of a desk presses into your forearms or when the front edge of a seat places excessive pressure behind the knees.
NIOSH recommends avoiding prolonged contact between the forearms or wrists and hard, unpadded work-surface edges.
At your desk: check seat depth, desk edges, armrest positions, and wrist placement. Comfort should come from appropriate support, not from pressing your body against a hard surface.
8. Provide Enough Clearance
Your body needs enough space to move.
Check underneath your desk. If boxes, cables, drawers, or computer equipment force your legs into a narrow position, your posture may be compromised even if you have an ergonomic chair.
At your desk: maintain enough clearance for your knees and feet, and make sure your chair can move close enough to the work surface without obstruction.
An ergonomic workspace should accommodate the user, not force the user around the furniture.
9. Move and Change Positions Regularly
Furniture is only one part of ergonomics.
Movement is equally important. Standing up, walking briefly, stretching, and switching between tasks can break up long periods of static or repetitive work.
NIOSH notes that short breaks can help reduce discomfort among people who work on computers.
Instead of trying to maintain the same “ideal” sitting position for an entire workday, build opportunities for movement into the way you work.
10. Create a Comfortable Work Environment
Ergonomics extends beyond the chair and desk.
Lighting, glare, noise, temperature, available space, and equipment placement can all influence how comfortably you work.
For example, screen glare may encourage you to lean forward or change your head position just to see the display clearly.
NIOSH recommends positioning displays and managing surrounding light to reduce glare and improve viewing comfort.
A well-designed workstation therefore considers both your body and the environment around it.
A 5-Minute Ergonomic Workstation Check
You do not need specialist equipment to identify some of the most obvious workstation problems.
Start by checking whether:
- Your feet have stable support.
- Your lower back is supported.
- Your shoulders remain relaxed while typing.
- Your keyboard and mouse are within easy reach.
- Your wrists stay relatively straight and aligned with your forearms.
- The top of your monitor is around eye level or slightly below.
- There is enough space underneath the desk for your legs.
- Frequently used items are close to your body.
- Glare does not interfere with your screen.
- Your workstation allows you to change positions.
Many of these points are also included in OSHA's computer workstation guidance.
If several answers are “no,” you may not need to replace everything immediately. Start with simple adjustments to chair height, monitor position, keyboard and mouse placement, and desk organization.
Does Ergonomic Furniture Automatically Create an Ergonomic Workspace?
No.
An “ergonomic” chair does not automatically create a good workstation if its seat, backrest, armrests, seat depth, and other adjustments do not fit the person using it.
Instead of only asking:
“Is this chair ergonomic?”
A better question is:
“Can this chair be adjusted to fit my body and the way I work?”
For example, the PEXIO x HBADA Evolve 3 Ergonomic Office Chair includes adjustable seat height, a sliding seat, lumbar support, headrest, and armrests, giving users several ways to configure their sitting position.
If you are still deciding what features matter, start with PEXIO's guide to ergonomic work chairs, their benefits, and key criteria.
Build a Workspace That Adapts to You
Ergonomic principles are not about forcing yourself to maintain a “perfect” posture all day.
They are about creating a workspace that makes comfortable positions, efficient movement, and regular posture changes easier.
Start small. Adjust your chair. Bring your mouse closer. Reposition your monitor. Clear the space underneath your desk. Then look at whether your furniture provides enough adjustability for your body and the way you work.
A truly ergonomic workspace should adapt to you, not the other way around.
