In a world where work-life often equates to hours spent in front of computers, the importance of ergonomics in the workplace has been skyrocketing. Understanding ergonomics and implementing it into your office environment can help boost productivity, minimise work-related injuries, and increase job satisfaction.
What is Ergonomics?
Ergonomics, sometimes referred to as human factors, is a scientific discipline that seeks to understand and optimise the interactions between humans and other elements of a system. The goal is to design and arrange workplaces, products, and systems in a manner that aligns with human capabilities and limitations.
This science involves incorporating knowledge from a variety of fields including biology, psychology, engineering, and design. These principles are used to design environments that enhance safety, performance, and satisfaction.
The concept of ergonomics has been around for centuries, but it was not formally recognised as a scientific discipline until the 20th century. The term "ergonomics" itself was coined in 1857 by Polish scientist Wojciech Jastrzębowski in his book which translates as "An outline of ergonomics, i.e. the science of work, based on the truths drawn from the Science of Nature". However, it wasn't until the aftermath of World War II, where there was a pressing need to improve the efficiency and safety of workers, that ergonomics began to be widely applied.
Over the years, ergonomics has evolved to tackle broader issues of human interaction with systems and the impact these interactions have on human well-being and overall system performance. Today, it is integral to designing tasks, jobs, products, environments, and systems to be compatible with the needs, abilities, and limitations of people.
Understanding ergonomics helps us to create environments that fit the people who use them, rather than forcing people to fit into poorly designed environments. This approach reduces discomfort, enhances productivity, minimises the potential for physical strain or injury, and improves the overall quality of life for individuals at work.
What is an Ergonomic Chair?
An ergonomic chair is a specially designed piece of office furniture that significantly contributes to supporting the correct posture of the user, minimising potential physical strain and discomfort. Unlike standard office chairs, ergonomic chairs are adaptable to individual needs and work environments.
Key features of an ergonomic chair include:
Seat Height: The chair's height should be easily adjustable, typically with a pneumatic adjustment lever. When seated, your feet should rest flat on the floor, and your thighs should be parallel to the ground.
Seat Width and Depth: The seat should have enough width and depth to support any user comfortably. Ideally, the depth (from front to back) should be enough so that the user can sit with their back against the backrest while leaving approximately 2 to 4 inches between the back of the knees and the seat of the chair.
Lumbar Support: The lower back support is crucial. An ergonomic chair should have a lumbar adjustment (both height and depth) so each user can get the proper fit to support the inward curve of the lower back.
Backrest: The backrest should be adjustable in height and angle. It should be able to support the natural curve of the spine, with special attention to proper support of the lumbar region.
Armrests: They should be adjustable, allowing the user's arms to rest comfortably and shoulders to be relaxed. The elbows and lower arms should rest lightly, and the forearm should not be on the armrest while typing.
Swivel: The chair should easily rotate so the user can reach different areas of their desk without straining.
Seat Material: The material on the chair seat and back should have enough padding to be comfortable. It should also be breathable to keep the user from getting too hot after prolonged sitting.
Headrest: Some ergonomic chairs also come with a headrest, which is especially useful for people with neck problems.
By offering this array of adjustable features, an ergonomic chair can accommodate the unique needs of each individual, promoting healthier sitting habits, improving comfort, and potentially increasing productivity.

How to Have Good Posture at Work
Maintaining good posture at work is paramount for physical wellbeing. It involves aligning your body in such a way that the strain on your muscles and joints is minimised. Here are a few tips:
Adjust your chair height so your feet are flat on the floor and your knees are at a 90-degree angle.
Your monitor should be at eye level, about an arm's length away.
Keep your back flush against the chair, utilising the lumbar support.
Keep your shoulders relaxed and your forearms parallel to the ground.
Benefits of an Ergonomics in the Workplace
Investing in ergonomic office furniture offers several advantages:
Reduced risk of musculoskeletal disorders: Ergonomic chairs and adjustable desks help reduce the risk of back pain, carpal tunnel syndrome, and other musculoskeletal issues.
Improved productivity: Comfortable workers tend to be more productive and engaged in their tasks.
Increased job satisfaction: A comfortable work environment can lead to greater job satisfaction and morale among employees.
Ergonomic equipment doesn't stop at chairs and desks; consider items like ergonomic keyboards, mice, and monitor risers to further enhance your workspace.
Ergonomic Examples
Several examples of ergonomics in the workplace include:
Ergonomic chairs: These chairs have adjustable components to meet individual needs.
Sit-stand desks: These desks allow employees to alternate between sitting and standing, reducing prolonged static postures.
Document holders: These devices can be adjusted to eye-level, preventing neck strain.
Footrests: These can help maintain correct sitting posture, especially for those whose feet do not comfortably reach the floor.
Ergonomic keyboards and mice: These are designed to promote a natural hand, wrist, and forearm position.
Conclusion
The science of ergonomics is not just a passing trend but a fundamental aspect of designing a healthy, productive, and efficient workspace. By recognising and applying ergonomic principles, we take a proactive step towards improving the health, safety, and happiness of individuals within a workspace.
The shift towards ergonomics not only acknowledges our unique physical needs but also reflects a broader understanding of how our environment impacts us - physically, mentally, and emotionally. It emphasises the need to design work around people, considering their capabilities and limitations, and understanding how they interact with tools, systems, and environments.
Investment in ergonomic furniture like ergonomic chairs and equipment demonstrates a company's commitment to the well-being of its employees. These changes can lead to remarkable improvements in productivity, job satisfaction, and a reduction in work-related injuries. It creates an environment that encourages workers to perform their best while maintaining their health, resulting in a more positive work experience overall.
In an age where work-related stress and sedentary lifestyles are prevalent, ergonomics provides tangible solutions. Remember, effective ergonomics is about more than just the individual components; it's about creating an integrated, comfortable environment that supports employees' diverse needs. As we move forward, let's continue to prioritise ergonomics as a critical component of workplace design and culture. It's not just about making work fit the worker; it's about shaping a healthier, more satisfying future of work.
