The ultimate guide to office ergonomics in health and safety in 2026

Office ergonomics is one of the most cost-effective investments a business can make in employee health and safety. Poorly set-up workstations are a leading cause of the aches, strains and lost days that quietly drain productivity, yet most of the fixes are simple and inexpensive.

This office ergonomics guide walks health and safety managers through what ergonomics actually is, why it matters, and the practical adjustments, from desk and chair setup to lighting, movement and home working, that make a real difference for office workers. If your workplace has not reviewed its setup recently, it is a quick win worth prioritising.

Why is office ergonomics important?

Creating a comfortable and safe working environment is essential for employee well-being and productivity. Poor office ergonomics can lead to a range of health issues, including musculoskeletal disorders (MSDs), repetitive strain injuries (RSI), and chronic fatigue. By optimising office ergonomics, businesses can enhance efficiency, reduce absenteeism, and improve overall workplace satisfaction.

The Health and Safety Executive (HSE) reports that work-related musculoskeletal problems affect approximately 469,000 workers across Britain, leading to 6.6 million lost working days and costing the economy £15 billion annually. With this in mind, investing in ergonomics is not just beneficial but necessary.

What is office ergonomics?

Ergonomics is the study of designing workplaces that fit the needs of employees to improve performance and efficiency while reducing the risk of injury. Put simply, the office ergonomics definition is the practice of arranging your desk, chair, screen and equipment around the person, rather than forcing the person to adapt to a fixed setup. Though commonly associated with office environments, ergonomics applies across industries, from retail to manufacturing and construction.

Key office ergonomics adjustments (how to improve office ergonomics)

A well-designed office should promote comfort, movement, and efficiency. Below are essential ergonomic changes to implement if you are looking at how to improve office ergonomics in your workplace:

Setting up an ergonomic desk

Most employees spend their workday at a desk, making it crucial to optimise their workstation setup. Consider the following adjustments:

• Monitor placement: The top of the screen should be at or slightly below eye level to reduce neck strain. Adjustable monitor arms can help achieve this.
• Ergonomic keyboards & mice: A keyboard with wrist support and a properly positioned mouse reduces hand tension and prevents RSI.
• Document holders: If employees frequently refer to documents, a document holder placed at eye level can prevent neck strain.

Top tip from the Mayo Clinic on monitor placement: 

“Place the computer monitor straight in front of you, directly behind your keyboard, about an arm’s length away from your face. The monitor should be no closer to you than 20 inches (about 50 centimeters) and no further away than 40 inches (about 100 centimeters)” 

This great video from Mayo Clinic may be a little dated on the equipment, but it still provides some great advice on ergonomic optimisations at the desk:

Choosing the right office chair (what to look for)

If you are wondering what to look for in an office chair, or how to adjust and choose one for good ergonomics, posture support is the priority. A well-designed chair supports posture, preventing lower back, neck, and shoulder pain. The best office chairs should:

• Be height-adjustable so feet rest flat on the floor.
• Support the lower back with lumbar cushioning.
• Have armrests positioned to allow a 90-degree elbow angle.

To adjust an office chair correctly, set the height first so your feet sit flat and your knees are level with or just below your hips, then adjust the backrest and lumbar support to meet the natural curve of your spine, and finally set the armrests so your shoulders stay relaxed.

The below diagram from Mayo Clinic shows the best way to sit at your desk: 

Standing desks & sit-stand workstations

Sitting for long periods is associated with various health risks, including obesity, cardiovascular disease, and musculoskeletal disorders. Implementing sit-stand desks helps mitigate these risks by allowing employees to alternate between sitting and standing throughout the day.

A study by the University of Leicester found that widespread standing desk use improved employee productivity and health. Standing desks can also help you prevent the chances of musculo-skeletal diseases (MSDs). 

Setting up home office ergonomics

With hybrid and remote working now the norm, home office ergonomics matter just as much as the main office, and employers still have a duty of care for home workstations. To set up home office ergonomics on a budget, apply the same principles: get the screen to eye level (a stack of books works if you do not have a monitor arm), use a separate keyboard and mouse with a laptop, support the lower back in whatever chair is available with a cushion, and avoid working from the sofa or bed for long stretches. A quick DSE self-assessment helps remote workers spot the gaps.

Encouraging screen breaks

To prevent eye strain and fatigue, encourage employees to take regular screen breaks. The 20-20-20 rule is a simple and effective strategy: every 20 minutes, look at something 20 feet away for 20 seconds.

Office lighting & environment

Lighting plays a crucial role in office ergonomics. Poor lighting can cause eye strain, headaches, and reduced concentration. Ensure the following:

• Maximise natural light exposure.
• Use adjustable LED lighting for task-focused activities.
• Reduce glare on computer screens by positioning monitors perpendicular to windows.

Alternative workspaces

Modern offices are moving away from rigid desk setups and incorporating lounge-style work areas. These spaces allow employees to change their posture, reducing strain and boosting creativity.

• Open spaces with high ceilings encourage collaborative work.
• Quiet areas provide focused working environments.
• Plants and natural elements can enhance mood and productivity.

Encouraging movement & active workdays

Even with ergonomic setups, prolonged sitting can be detrimental to health. Encourage employees to move throughout the day by:

• Implementing walking meetings.
• Encouraging stair use instead of elevators.
• Designing an office layout that promotes movement.

Conclusion: Investing in ergonomics for long-term benefits

Health and safety managers should prioritise ergonomics as a core part of workplace safety. By optimising office setups, providing ergonomic equipment, and fostering a culture of movement and flexibility, businesses can enhance employee well-being and operational efficiency.

Adopting these principles can help prevent workplace injuries, reduce absenteeism, and create a more productive and satisfied workforce. Whilst it can sometimes seem as obvious or patronising, getting your staff on board with ergonomics and making it a part of their day will support both well-being and business performance.
