AFRDI Chair Ratings Explained: How to Choose the Right Ergonomic Office Chair in Australia

With a long list of features and specifications to weigh up, how do you choose the right ergonomic office chair for you?

Online reviews and tips from colleagues are helpful. But they don’t account for your personal comfort and support requirements. 

Thankfully, there are manufacturer ratings and certifications that indicate a chair’s quality. These standards guide you towards reliable choices, helping you narrow your shortlist.

In this guide, we explain how to choose the right ergonomic office chair for you by combining quality standards such as AFRDI with a personalised fit. 

What is an “AFRDI Office Chair”?

The Australasian Furnishing Research and Development Institute (AFRDI) is an independent body that tests and certifies furniture for safety, strength, and durability. Their Blue Tick is the key quality mark to look for when shopping for an office chair in Australia.

Here’s what the certification covers:

• Structural durability: Thousands of load cycles simulate years of real-world use across the seat, back, arms, and base
• Ergonomic compliance: Tested against AS/NZS 4438:1997, confirming the chair can be safely adjusted to suit 90% of the adult population
• Stability and safety: Tipping resistance and rolling stability are independently verified
• Performance levels 4, 5, and 6: Level 6 is the commercial benchmark required by many government and education tenders
• Weight ratings: Standard certification covers chairs rated for users up to 110 kg; AFRDI 142 covers 135 kg, 160 kg and 185 kg chairs across single and multi-shift use

It’s important to note that AFRDI does not measure comfort. Comparing two Level 6 certified chairs will feel completely different. Certification confirms a chair is safe and adjustable, not that it’s right for your body.

Why the Right Ergonomic Chair Matters

Unsurprisingly, the chair you sit in every day has a direct impact on your body. According to Safe Work Australia, body-stressing injuries accounted for 34.5% of all serious claims in 2025. Many of the musculoskeletal disorders affecting more than 50,000 workers are preventable. The right chair is one of the most practical steps you can take.

The Impact of Poor Seating on Posture, Comfort, and Productivity

Over time, even the slightest mismatch between your chair and your physical requirements can add up. Without the right chair for your body, you can experience: 

• Slouched posture and strain on your spines
• Lower back discomfort, pain or stiffness
• Neck and shoulder tension
• Reduced focus and productivity
• Fatigue from continual adjustments

An ergonomic chair that adjusts to your needs can eliminate these negative effects, so you can focus on the day ahead.

Why the Best Chair Depends on You

There’s no single best ergonomic office chair in Australia. And the chair that’s right for your colleague isn’t always right for you. 

Instead, the best chair for you is the one that suits your needs. So, look for features that match:

• Your height and body shape
• How many hours you sit on it each day
• The type of work you do 
• Whether you have any special requirements for a chair

Whether it’s an ergonomic chair for long hours in the office or a gaming chair for mobility, you want a chair that gives you the most in comfort and support.

What to Look for in an Ergonomic Office Chair

In addition to AFRDI certification, a good ergonomic office chair should offer adjustability, support, and quality materials. Even the slightest difference in features can make a big impact on how a chair feels for you, so keep these in mind.

Adjustability: The Foundation of Comfort

One of the key features of an ergonomic chair is that it allows you to fine-tune your seating position. With varying degrees of adjustability, and different parts of the chair you can adjust, it’s possible to move armrests, seat height, seat depth, and backrest to suit you exactly.

For example, the OVICA High Back Ergonomic Office Chair features height and tilt adjustments for the back and seat, with optional adjustable arms or seat slide. All this flexibility supports a range of users and work environments. 

Support: For All-Day Comfort

Support is crucial when you spend long hours sitting in a chair. Key office chair support features to look for include:

• Lumbar support to maintain the natural curve of your spine
• Upper back support for stability
• Quality cushioning to reduce pressure points and provide comfort

Without proper office chair lumbar support, you could spend your day slouching or constantly shifting positions just to feel comfortable.  And where you can introduce as much movement as possible into your day & tasks.

Materials and Finish: Mesh vs Upholstered

In addition to its appearance, the material of your ergonomic office chair will affect its comfort and durability. One thing you’ll notice as you shop around is that task chairs are typically categorised as “mesh back” or “upholstered back”.  

Mesh back chairs are pliable and breathable, offering movement across the back support  and comfort in warmer environments. Upholstered back chairs typically offer more defined structure and support along with that all-important cushioned feel.

AFRDI office chair certification covers both mesh and upholstered models, so it’s simply a matter of which you prefer.

Your Setting: Workplace or WFH?

Where you use your chair might influence what you prioritise. Home office users can focus on personal fit and comfort. If you’re the only user, choose a chair tailored to your body and workspace.

Multi-user comfort and adjustability become more important in shared workplaces. The chair needs to work across different heights, weights, and comfort preferences. 

AFRDI Level 6 certification also carries more weight here. It supports WHS compliance, demonstrates due diligence, and is a minimum requirement for many government and education procurement tenders.

If chairs will see heavy or multi-user daily use, prioritise durability and certification over price. A cheaper, non-certified chair may cost more in the long run through faster wear, unsuitability and discomfort, or earlier replacement.

How to Choose an Ergonomic Chair for Your Body Type

Think of your new ergonomic office chair as a piece of clothing: it needs to fit your body, otherwise it just won’t work. To ensure you choose the right chair, check these things off.

Suitability for Your Height

Check a seat’s dimensions, seat depth and height range, and backrest height to ensure they match your physical requirements. For taller users, a chair like the Impact Heavy Duty Ergonomic Chair, with a backrest height of 615 mm and AFRDI’s Blue Tick Certification, might be your perfect match.

Seat Depth and Width

A chair should be wide enough to seat you comfortably, without any overhang. Its depth should also be enough to support your thighs without the seat pressing into the backs of your knees.

Weight Capacity 

All quality ergonomic office chairs are weight-rated, so you can find the exact fit you need as you shop around. The weight a chair can hold can impact its safety, durability, and comfort, so it’s a vital feature.

While it’s easy to check online reviews to get an idea of a chair’s build quality or how to set it up ergonomically, they can’t account for your comfort and physical requirements.
