The Science of Ergonomics: How to Choose an Office Chair That Supports Your Posture

Whether operating from home or heading to a place of business, many Australian workers spend a good chunk of their days sitting in an office chair. This regular practice comes with its health-related downsides, which is where the business of ergonomics comes into play. In the workplace, the science of ergonomics plays a crucial role in creating an environment that supports employee health, comfort, and productivity. And one of the most important ergonomic considerations is the office chair. 

In this blog, we will explore how ergonomics apply to office chairs and discuss their key features. We will also provide tips for adjusting and using an ergonomic office chair effectively and look at selecting the right one and maintaining it to ensure you are enjoying its benefits long term. 

Understanding Ergonomics and Its Benefits

What is Ergonomics? 

By definition, ergonomics is the science of designing products, systems, and processes to optimise human well-being and performance. In the context of office furniture design, ergonomics aims to create workspaces that support the natural posture and movement of the human body, reducing the risk of musculoskeletal disorders and promoting overall health. 

Health Benefits of Ergonomic Chairs 

Making your next office chair purchase a smart one ergonomically could be hugely beneficial for your long-term health. Using an ergonomic office chair can both reduce back pain and improve circulation. These chairs are designed to support the natural curve of the spine, alleviating pressure on the back and neck. By preventing poor posture, ergonomic office chairs can help prevent long-term health issues such as spinal degeneration, herniated discs, and chronic pain.

Key Features of an Ergonomic Office Chair

Adjustable Seat Height 

We’ve all seen the lever that adjusts the seat height of an office chair used for the occasional office prank – but getting your chair height just right is no joke when it comes to posture. When the seat height is correctly adjusted, your feet should rest flat on the floor or on a footrest, with the knees at or below hip level. For optimal posture and comfort, adjust the seat so your elbows are at a 90-degree angle and your wrists are straight.

Lumbar Support 

So, what exactly is lumbar support? Well, ergonomics is at play again here; lumbar support is a critical feature of any ergonomic chair, designed to fill the gap between the lumbar spine and the seat to support the natural inward curve of the lower back. When properly adjusted, the lumbar support should fit snugly into the small of your back. To find the optimal position, sit back in the office chair and adjust the lumbar support until you feel a comfortable amount of pressure in your lower back.

Seat Depth and Width 

The seat depth and width of an office chair are all about finding the specific fit for you. The seat should be wide enough to accommodate the user comfortably, while the depth should allow the user to sit with their back against the backrest while leaving 5-10cm between the back of the knees and the seat. When choosing a chair (some do have adjustable depth), consider your body type and size. 

Additional Features to Consider

Armrests 

They might feel like an afterthought, but adjustable armrests are worth consideration when selecting an ergonomic office chair due to the support they offer the shoulders and upper back, reducing strain and fatigue. Armrests should be at elbow height, allowing your arms to rest comfortably without raising your shoulders. 

Backrest and Recline 

The backrest of an ergonomic chair should provide ample support for the spine while allowing for a comfortable recline. A well-designed backrest follows the natural curve of the spine, providing extra support in the lumbar region. The ability to recline slightly, typically between 100-120 degrees, helps reduce pressure on the lower back. 

Material and Padding 

The best office chair in terms of material and padding largely comes down to breathability and durability. Mesh office chairs provide excellent breathability, while leather office chairs offer a luxurious look and feel and are often the choice for those seeking an executive office chair. They are generally more durable but can be less breathable. Fabric chairs strike a balance between the two. High-quality padding is essential for comfort and prolonged use, with high-density foam a popular choice for its resilience and ability to retain its shape.

How to Choose the Right Ergonomic Chair for You

Assessing Your Workspace 

When selecting an ergonomic office chair, assess your workspace to ensure the chair aligns with your desk setup. Consider desk height and available space. Your chair should easily slide under the desk with sufficient legroom. Before purchasing, measure the space where you chair will be placed to ensure it won’t crowd the area or interfere with other furniture. 

Budget Considerations 

It’s important to get the juggle right between quality and budget to ensure you’re getting value for money with your chair.  While it may be tempting to opt for the cheapest option, investing in a well-constructed, ergonomic office chair is an investment in your health. Look around for chairs that offer the essential ergonomic features, such as adjustable lumbar support, seat height, and backrest tilt, without compromising on quality. Some of the best office chairs in Australia meet ergonomic standards while still being affordable.

Maintaining Your Ergonomic Chair

Regular Cleaning and Maintenance 

Remember: your office chair is an investment – regular cleaning and maintenance are essential for preserving its longevity and performance. Wipe down the chair with a damp cloth and mild soap for fabric chairs, and use a leather cleaner and conditioner for leather office chairs. Keep an eye out for loose screws or worn parts and tighten or replace them as needed. 

Adjustments and Upkeep

Regularly inspect and adjust your ergonomic office chair to maintain its comfort and functionality. Check for proper alignment, adjust the lumbar support, and ensure the seat height and armrests are at the correct positions. Perform minor repairs, such as tightening loose screws or replacing worn-out parts. If you’re unsure or encounter complex issues, ask an expert.
