Dynamic ergonomic seating that moves with you
Don't Want to Spend Your Workday Locked into One Chair Position?
Many ergonomic chairs give you plenty of adjustment, but once those settings are chosen, the seat and backrest largely remain where you put them.
The Ergo Synchro Ergonomic Chair takes a more dynamic approach. Its weight-activated synchro mechanism allows the seat and backrest to move together as you change position throughout the day.
You still get important fit adjustments including seat height, seat depth and manual backrest height, but the chair is designed to encourage movement rather than keeping you in one fixed seated posture.
Sit forward to work. Lean back to think. Let the chair move with you.
The synchro mechanism coordinates movement between the seat and backrest, helping the chair maintain supportive contact as your sitting position changes.
Built for People Who Move While They Sit
SYNC
Synchro Movement
The seat and backrest move in a coordinated way as you recline rather than acting as two completely independent fixed surfaces.
↔
Seat Depth Adjustment
Adjust how much of the seat sits beneath your thighs to better suit different leg lengths and body dimensions.
↕
Adjustable Back Height
Move the backrest vertically so its supportive contour sits in a more appropriate position against your back.

Commercial-grade certification for strength, durability and demanding everyday workplace use.
What Does a Synchro Chair Actually Do?
When you recline in a synchro chair, the backrest and seat pan move together at different rates.
The backrest generally reclines further than the seat, allowing your body to open into a more relaxed position without simply tipping the entire chair backwards as one rigid unit.
This coordinated movement helps you transition between upright task work and more reclined sitting without repeatedly adjusting multiple levers.
Rather than asking you to find one supposedly perfect posture and maintain it all day, the chair is designed to accommodate movement between positions.
Because the Best Sitting Position Is Often the Next One
Even a well-fitted ergonomic chair should not be treated as somewhere to remain completely still for eight hours.
The Ergo Synchro is designed to make small posture changes easier by allowing the chair to respond as you move.
- Sit upright for focused keyboard work
- Lean back during reading or thinking
- Change position during calls
- Move rather than maintaining one rigid posture
- Adjust seat depth around your leg length
- Reposition the backrest around your lumbar region
Less Time Managing Levers, More Natural Chair Movement
The weight-activated synchro mechanism responds to the user as they move rather than relying entirely on a manually fixed backrest position.
This can make the chair particularly appealing if you want substantial ergonomic adjustment without needing to constantly change the chair throughout the day.
i
Automatic movement doesn't mean no setup. Seat height, seat depth and backrest height still need to be adjusted around your body before the synchro mechanism can work from a suitable starting position.
Dynamic Movement with the Fit Adjustments That Still Matter
The Ergo Synchro combines movement with several manual adjustments that help fit the chair to the person using it.
H
Seat Height
Adjust the chair between approximately 49cm and 59cm high to suit your legs and work-surface height.
D
Seat Depth
Change the effective seat depth so the chair supports your thighs without pressing excessively behind the knees.
A
Seat & Back Movement
The synchro mechanism coordinates the chair as you move between upright and reclined sitting positions.
B
Manual Back Height
Raise or lower the backrest so its supportive shape better aligns with your individual back.
Seat Depth Matters More Than Many People Realise
A chair seat that is too deep can press against the back of the knees or make it difficult to sit against the backrest.
A seat that feels too short may provide less support beneath the thighs.
The Ergo Synchro includes seat-depth adjustment so you can fine-tune how the 51cm seat pan relates to your leg length.
i
A useful starting point: sit fully against the backrest and adjust the seat so you have comfortable clearance behind your knees while maintaining support beneath the thighs.
Move the Backrest to Your Back, Not the Other Way Around
People differ in torso length and where the inward curve of the lower back sits.
Manual back-height adjustment lets you move the entire backrest vertically rather than accepting one fixed lumbar position.
Adjust it until the shape of the backrest feels supportive without creating an excessive pressure point.
A Substantial Seat for Long-Hour Office Work
The Ergo Synchro uses a seat approximately 52cm wide × 51cm deep, providing a substantial sitting surface for everyday office use.
The backrest measures approximately 52cm high × 47cm wide.
These dimensions make it important to compare the chair with your own body dimensions rather than choosing a chair solely because it is described as ergonomic.
Particularly Suited to Long-Hour, Movement-Friendly Work
Long-Hour Office Work
Home Offices
Corporate Workstations
Dynamic Sitters
It is particularly well suited to someone who changes position throughout the day and wants the chair to accommodate those movements rather than continually returning to one fixed backrest angle.
Work Upright Without Staying Upright All Day
Focused keyboard and mouse work may naturally bring you into a more upright seated position.
Reading, thinking, phone calls and less intensive tasks may allow you to recline slightly.
The synchro mechanism makes moving between these positions part of normal chair use rather than requiring you to repeatedly unlock, reposition and relock the backrest.
AFRDI Level 6 Certified for Commercial Use
The Ergo Synchro is AFRDI Level 6 certified, providing independent assurance around the chair's strength, safety and durability for demanding office environments.
It is load rated to 135kg, making it suitable for a broad range of users within the chair's specified limits.
This makes it equally relevant to an individual home-office user or an organisation specifying chairs across commercial workstations.
Upholstered and Assembled in Australia
The chair is upholstered and assembled locally in Australia and uses anti-bacterial foam within the upholstered seating components.
This gives the Ergo Synchro a distinctly commercial workplace specification rather than positioning it as a lightweight consumer office chair.
Synchro Chair or Traditional Multi-Lever Ergonomic Chair?
SYNC
Choose the Ergo Synchro If...
You prefer a chair that moves dynamically with you and want less need to manually choose and maintain one fixed backrest angle.
MAN
Consider a Multi-Lever Chair If...
You prefer independently setting and locking seat and backrest positions exactly where you want them using separate manual controls.
Looking at Other Synchro Chairs in Our Range?
The Ergo Synchro is designed around a traditional upholstered ergonomic office-chair format with manual back-height adjustment and a dynamic weight-activated synchro mechanism.
If you're comparing several chairs, consider the dimensions, backrest design, available options and how each chair fits your body rather than choosing on mechanism alone.
The synchro mechanism is an important feature, but seat height, seat depth, backrest shape and your workstation dimensions still determine whether a chair is appropriate for you.
Get the Fit Right Before You Let the Chair Move
1
Set the Seat Height
Adjust the chair around your desk and legs so your feet are supported and your shoulders can remain relaxed while working.
2
Adjust Seat Depth & Back Height
Fine-tune the seat beneath your thighs and position the backrest around the natural curve of your back.
3
Allow the Synchro Mechanism to Work
Once the chair fits you, allow yourself to move between more upright and reclined positions rather than attempting to remain perfectly still.
Dynamic doesn't mean unlimited sitting
A Chair That Moves with You Still Doesn't Replace Getting Up and Moving
Synchro movement can increase variation while you are seated, but it does not remove the value of standing, walking and changing tasks throughout the day.
Use the chair's movement as one part of a more varied working routine rather than treating any seated position as something to maintain indefinitely.
Choosing a New Chair Because Sitting Has Become Uncomfortable?
A well-fitted chair can change the way your body is supported and give you more options for movement during the day.
However, no ergonomic chair can guarantee relief from back, neck, hip or other musculoskeletal symptoms.
Chair fit, workstation height, keyboard and mouse position, sitting duration and individual health factors can all affect comfort.
If you have significant or persistent symptoms, consider discussing your workstation with a physiotherapist, occupational therapist or other appropriate health professional.
