Most Recommended Office Chair: Best ONEX Picks for Australia

Choosing the most recommended office chair is not simply about finding the chair with the most features. The right choice depends on how long you sit, your body size, your desk setup and the type of support you prefer.

A good ergonomic office chair should help you maintain a comfortable sitting position while giving you enough adjustment to suit your workspace. Features such as seat height adjustment, lumbar support, armrests, a supportive backrest and recline controls can all make a noticeable difference during a long working day.

ONEX offers several office chairs designed for different budgets and seating preferences. In this guide, we compare four current models, the SKYFLEX, GE300, AIRNEST and VENTRA, to help you choose the right option for your home office, study or gaming setup.

Why Does an Ergonomic Office Chair Matter?

There is no single office chair that will suit everyone. Body dimensions, working habits, desk height and the tasks you perform all affect how comfortable a chair feels.

The Canadian Centre for Occupational Health and Safety notes that an ergonomic chair should suit the user's body dimensions, workstation and tasks rather than relying on a one-size-fits-all approach. Its guidance also highlights adjustable seat height, suitable back support and easy-to-use controls as important considerations when selecting a chair.

Your overall workstation matters as well. Healthdirect's posture guidance recommends keeping your back supported when sitting and your feet flat on the floor. It also notes that sitting for long periods can affect posture.

That means the best office chair for you should fit both your body and the way you work rather than simply having the longest feature list.

What Should You Look for in an Office Chair?

Before comparing individual ONEX models, consider the ergonomic features that are most relevant to your setup.

Seat Height and Seat Depth

The seat height should allow you to work comfortably at your desk without raising your shoulders. Ideally, your feet should remain supported by the floor or a footrest.

Seat depth is also important. A chair that is too deep can put pressure behind your knees, while a seat that is too shallow may not support enough of your thighs.

WorkSafe Queensland recommends leaving approximately two to three fingers of clearance between the front of the chair and the back of the knees. It also recommends choosing a seat and backrest that suit the individual user's dimensions.

If several people will use the same task chair, seat depth adjustment can be particularly useful.

Lumbar and Back Support

The backrest should support your lower back while allowing you to sit comfortably against the chair.

Some office chairs have fixed lumbar support, while others offer adjustable lumbar support that can be repositioned to better match the user.

OSHA recommends a backrest that follows the natural curvature of the spine and provides appropriate lumbar support. It also notes that increased adjustability can help a chair fit a wider range of users and sitting positions.

Armrests

Armrests should support your forearms without forcing your shoulders upwards.

Different chairs provide different levels of adjustment. Basic models may use fixed or flip-up armrests, while others have one-dimensional or 3D armrests that provide more positioning options.

The important point is not simply how many directions an armrest moves. It needs to fit your desk and allow you to keep your shoulders relaxed.

Mesh or Cushioned Seating

A mesh office chair can be a practical choice if breathability is important to you. Mesh allows more airflow through the backrest and, depending on the design, the seat.

A padded seat cushion provides a softer and more traditional sitting feel. Neither option is automatically better. Your preference will depend on how you sit and the type of support you find comfortable.

Recline and Tilt Tension

A recline function allows you to change your sitting position instead of remaining in exactly the same posture throughout the day.

Tilt tension determines how much resistance you feel when leaning back. Being able to change position is useful because prolonged static sitting can become uncomfortable.

Cornell University's workstation guidance likewise recommends arranging a workstation around the individual rather than assuming there is one correct setup for everyone.

Recommended ONEX Office Chairs Compared

Prices and specifications are based on ONEX's current product listings and may change.

ONEX SKYFLEX Mesh Gaming Office Chair

At $299, the ONEX SKYFLEX Mesh Gaming Office Chair is the lowest-priced model in this comparison.

The SKYFLEX combines a flexible mesh backrest with a high-density foam seat cushion. ONEX lists adjustable chair tilt from 3° to 18°, tilt tension control and flip-up armrests.

Its simpler adjustment system makes it better suited to buyers who want a straightforward desk chair without paying for features they may not use.

The SKYFLEX has a maximum weight capacity of 100 kg and is rated by ONEX for approximately three to five hours of use. It does not have seat depth adjustment or dedicated lumbar adjustment, so users who spend a full working day at their desk may want to consider one of the models below instead.

Best suited to: shorter work sessions, study spaces and buyers looking for an affordable mesh-back chair.

ONEX GE300 Breathable Ergonomic Gaming Office Chair

The ONEX GE300 Breathable Ergonomic Gaming Office Chair is a stronger choice for people who need more adjustment for longer sitting periods.

Its standout feature is its adjustable seating system. The GE300 includes built-in adjustable lumbar support, seat depth adjustment and a headrest that can be adjusted for both height and angle.

It also offers a 90° to 135° adjustable back tilt and uses a synchro mechanism. The chair has a Class 4 gas lift, a maximum weight capacity of 125 kg and an ONEX usage rating of eight hours or more.

Unlike the AIRNEST and VENTRA, the GE300 uses one-dimensional adjustable armrests, so users who place a high priority on armrest movement should compare it with the AIRNEST.

For buyers looking for an ergonomic desk chair around the $400 price point, however, the combination of lumbar adjustment, seat depth adjustment and a breathable backrest makes the GE300 worth considering.

Best suited to: home offices, longer workdays and users who want adjustable lumbar and seat depth support.

 

ONEX AIRNEST Mesh Gaming Office Chair

The ONEX AIRNEST Mesh Gaming Office Chair costs $449 and provides one of the broadest adjustment packages in the current ONEX office-chair range.

The chair uses nylon mesh for both the back and seating area, making it particularly relevant for users who prefer a breathable mesh office chair.

Its ergonomic features include height-adjustable lumbar support, an adjustable headrest, 3D armrests, seat depth adjustment, tilt tension control and a synchro mechanism.

The AIRNEST also includes a retractable footrest, which provides an additional option when reclining during breaks.

ONEX rates the chair for eight or more hours of use and lists a maximum weight capacity of 125 kg.

Because both the lumbar support and seat depth can be adjusted, the AIRNEST gives users more flexibility to tune the chair around their body proportions.

Best suited to: full working days, users who prefer full mesh seating and buyers wanting greater adjustability.

 

ONEX VENTRA Premium Mesh Gaming Office Chair

At $549, the ONEX VENTRA Premium Mesh Gaming Office Chair sits at the highest price point among these four models.

The VENTRA uses nylon mesh across the back and seat and includes an adjustable headrest, 3D armrests, a synchro mechanism and tilt tension control.

ONEX rates it for eight or more hours of use, with a maximum weight capacity of 125 kg.

One important distinction is that its lumbar support is fixed rather than height adjustable, and ONEX does not list seat depth adjustment for this model. Buyers should therefore avoid assuming that the highest-priced chair automatically provides the greatest number of adjustments.

Instead, the VENTRA is more suitable for someone who values breathable mesh seating, 3D armrests and its overall seating design, provided the fixed lumbar position suits their body.

Best suited to: long work sessions and users who prefer a premium full-mesh design with 3D armrest adjustment.

 

Which ONEX Office Chair Is Right for You?

There is no universal winner because each of these office chairs serves a slightly different type of user.

If your budget is the main consideration and you only need the chair for several hours at a time, the SKYFLEX is the simplest choice in this group.

If you want adjustable lumbar support and seat depth without moving above $400, the GE300 offers a stronger range of ergonomic adjustments.

If you prefer full mesh and want both seat depth adjustment and 3D armrests, the AIRNEST provides the most relevant combination of those features among these four models.

The VENTRA may appeal more to users who prefer its premium full-mesh construction and 3D armrests but do not require adjustable lumbar support or seat depth.

Ultimately, the most recommended office chair for your setup is the model that fits your body dimensions, working hours, desk and preferred sitting style.

 

How to Adjust Your Office Chair Properly

Even a well-designed chair can feel uncomfortable if it is not adjusted correctly.

Start with the seat height. Adjust it so you can work at your desk with relaxed shoulders and supported forearms. If this leaves your feet unable to reach the floor comfortably, use a footrest.

Next, sit against the backrest rather than leaning towards the front of the seat. If your chair has adjustable lumbar support, position it so that it comfortably supports the curve of your lower back.

For chairs with adjustable seat depth, leave enough room behind your knees to move freely. WorkSafe Queensland suggests approximately two to three fingers of clearance.

Finally, adjust your armrests so they support your arms without raising your shoulders. Your chair should also be close enough to the desk that you do not need to reach forwards to use your keyboard and mouse.

If you are rebuilding your workstation more broadly, pairing your chair with an appropriately positioned desk is equally important. ONEX also offers a range of standing desks for users who want the option to change between sitting and standing during the day.

 

Frequently Asked Questions

What Is the Most Recommended Office Chair for Long Hours?

For longer sitting periods, start by looking for a chair rated for extended use and then consider adjustment options such as lumbar support, seat depth, armrests and tilt controls.

Within the current ONEX range reviewed here, the GE300, AIRNEST and VENTRA are all listed for eight or more hours of use. Their adjustment options differ, so compare them according to your body and workspace rather than relying on the usage rating alone.

Is a Mesh Office Chair Good for Long Hours?

Mesh can be useful for people who value airflow and a firmer suspended seating feel. However, comfort is personal. Seat dimensions, back support and adjustability are just as important as the material itself.

Do I Need Adjustable Lumbar Support?

Not everyone requires the same type of lumbar support. CCOHS notes that a chair should fit the individual user rather than assuming one chair design suits everyone.

If you frequently struggle to get comfortable with fixed back support, an adjustable lumbar system may give you more flexibility.

Should an Office Chair Have a Headrest?

A headrest is not essential for every user, but it can provide additional support when reclining. The GE300, AIRNEST and VENTRA all include adjustable head support, while the SKYFLEX uses a fixed head support.

Can a Gaming Chair Be Used as an Office Chair?

Yes, provided its dimensions and ergonomic features suit the user and the type of work being performed. Rather than judging a chair solely by whether it is labelled a gaming chair or office chair, compare its seat height, backrest, lumbar support, armrests, weight capacity and adjustment options.

 

Find the Right ONEX Office Chair for Your Setup

The right chair should suit how you actually work. The SKYFLEX provides a simpler option for shorter sessions, the GE300 adds adjustable lumbar support and seat depth, the AIRNEST combines extensive adjustment with full mesh seating, while the VENTRA offers a premium mesh design with 3D armrests.

Before buying, compare the dimensions, weight capacity and adjustment range with your own body size and desk setup. You can view all current models and specifications in the ONEX office chair collection.
