Chair Mechanisms
Shop office chair mechanisms in South Africa from Bum Seating. Our range is designed for repairing, maintaining and upgrading office chairs used in offices, call centres, schools, home offices and commercial workspaces.
An office chair mechanism controls important chair functions such as tilt, height adjustment, recline movement and seating position. If your chair no longer tilts, locks, adjusts or feels stable, replacing the mechanism can help restore comfort and functionality.
Heavy Duty Office Chair Mechanisms
Chair mechanisms are one of the most important parts of an office chair. They connect the seat to the gas lift and help control how the chair moves and adjusts during use.
Our office chair mechanisms are suitable for:
Office chair repairs
High back office chairs
Medium back office chairs
Executive office chairs
Typist chairs
Task chairs
Call centre chairs
Home office chairs
Commercial office seating
Bulk chair repair projects
Replacement Chair Mechanisms
Replacing a damaged chair mechanism can be a cost-effective way to extend the life of an existing office chair. Instead of replacing the full chair, the correct mechanism can help restore proper movement and support.
Replacement chair mechanisms are commonly used when a chair no longer tilts correctly, feels loose, does not lock into position or no longer supports comfortable sitting.
Tilt and Lock Chair Mechanisms
Tilt and lock mechanisms allow users to adjust the chair’s movement and sitting position. These features can improve comfort during daily office use and help users find a better working posture.
Tilt mechanisms are commonly found on ergonomic office chairs, executive chairs, high back chairs and medium back office chairs.
Chair Mechanisms for Repairs and Maintenance
A faulty chair mechanism can affect the safety, comfort and performance of a chair. Replacing the mechanism is a practical repair option for offices, schools, call centres and businesses that want to maintain their existing seating.
Chair mechanisms are often replaced together with gas cylinders, bases or castors as part of a full office chair repair or refurbishment.

Frequently Asked Questions
What is an office chair mechanism?
An office chair mechanism is the part underneath the seat that controls chair movement, tilt, recline, height adjustment support and seating position.
When should I replace a chair mechanism?
You should replace a chair mechanism if the chair no longer tilts, locks, adjusts correctly, feels unstable or does not support the user properly.
Can I replace only the chair mechanism?
Yes. If the rest of the chair is still in good condition, replacing the mechanism can be a cost-effective way to repair the chair.
Are chair mechanisms universal?
Some chair mechanisms fit many standard office chairs, but compatibility can depend on the chair model, seat plate size and gas lift fitting.
Do you deliver chair mechanisms across South Africa?
Yes. Bum Seating supplies office chair mechanisms throughout South Africa, with delivery available to all nine provinces.
