An uncomfortable office chair is not always a bad chair. Often, the problem is the way the chair, desk, screen and your body are interacting. Small adjustments to seat height, back support and workstation position can make a noticeable difference to how comfortable the setup feels over a full workday.
Before replacing the entire chair, work through the basics. The best office setup is usually one that feels easy to maintain rather than one that forces you to sit perfectly still.
Set the chair height first
Start by adjusting the chair so your feet can rest comfortably on the floor or on a stable footrest. Your thighs should feel supported by the seat without excessive pressure behind the knees.
If the chair is too high, you may end up perching forward or letting your feet hang. If it is too low, your knees may sit noticeably higher than your hips and the desk can feel too tall.
Once the height feels right, check whether you can use your keyboard and mouse without lifting your shoulders. If the desk is fixed and the chair needs to be raised to match it, a footrest can help keep your lower body supported.
Use the backrest instead of hovering forward
Many people spend hours leaning slightly forward even though their chair has a backrest. This often happens because the screen, keyboard or chair depth encourages the body away from the back of the chair.
Move the chair close enough to the desk that you can work while still using the backrest. If your screen is too far away, bring it closer rather than moving your whole upper body forward.
Add lumbar support if the chair feels too flat
Some chairs have adjustable lumbar support built in. Others have a flat backrest that leaves a noticeable gap behind the lower back. A separate lumbar cushion can fill that space and make the chair feel more supportive without replacing it.
The important thing is placement. The cushion should sit in the lower back area rather than halfway up the spine. Too much thickness can push you too far forward, so choose a shape that supports you without making the seat feel cramped.
Our Ergonomic Seating Support Cushion is designed for office chairs, car seats and home seating where a little more structure behind the lower back is useful.
Check the seat depth
Seat depth is the distance from the backrest to the front edge of the seat. If the seat is too deep, you may struggle to sit against the backrest without the front of the chair pressing behind your knees. If it is too shallow, your thighs may feel under supported.
If your chair has a sliding seat pan, adjust it so you can sit back while leaving a small amount of space behind the knees. If it does not, a back support cushion can sometimes reduce the effective depth of a chair that feels too deep.
Position the screen so you do not chase it
A chair can feel uncomfortable because your workstation is pulling you out of it. Place the monitor directly in front of you and at a distance where text is easy to read without leaning forward.
The top portion of the screen should be around a comfortable eye level for you. Laptop users often benefit from raising the laptop on a stand and using an external keyboard and mouse, especially for longer work sessions.
Keep frequently used items close
If your mouse, phone or documents are constantly just out of reach, you will repeatedly twist or lean away from the backrest. Move frequently used items into the area you can reach while keeping your elbows close to your body.
This does not require a perfect minimalist desk. It simply means arranging the things you use most so they do not constantly pull you out of a comfortable position.
Use the armrests properly
Armrests can help support the arms, but only if they are in the right place. If they are too high, they can push the shoulders upwards. If they are too low, you may lean sideways to reach them.
Adjust them so your arms can rest naturally while your shoulders remain relaxed. If the armrests stop you getting close enough to the desk, lowering them or moving them out of the way may actually improve the setup.
Movement is part of a comfortable workstation
No chair adjustment makes sitting in one position all day ideal. Comfort usually improves when you change position regularly. Stand up, walk briefly, change tasks or simply reset your sitting position throughout the day.
A good chair setup should make sitting easier, but it should not make you feel as though you need to stay frozen in one posture for hours.
Do not overlook temperature and clothing
Chair comfort is also affected by heat, fabric and clothing. A chair that feels fine for an hour may become uncomfortable if the seat traps heat. Breathable clothing, airflow and a suitable chair surface can matter during long workdays, particularly in warmer Australian weather.

Frequently asked questions
Can a cushion make an office chair more comfortable?
It can, especially if the chair feels too flat or lacks support behind the lower back. The cushion still needs to suit the chair depth and your preferred sitting position.
Where should lumbar support sit on an office chair?
It should generally sit in the lower back area, not high between the shoulder blades. The exact position should feel supportive without pushing you noticeably forward.
Is a more expensive chair always more comfortable?
No. Adjustment range, proportions and how the chair fits your workstation can matter more than price alone.
How often should I change position?
There is no single perfect interval. A practical approach is to change position regularly throughout the day rather than waiting until you already feel uncomfortable.
