Shop office chair bases in South Africa from Bum Seating. Our range is designed for repairing, maintaining and upgrading office chairs used in offices, schools, call centres, home offices and commercial workspaces.
Office chair bases provide the foundation and stability of a chair. If a base is cracked, damaged or unstable, replacing it can help restore the safety and function of the chair without needing to buy a completely new one.
Heavy Duty Replacement Chair Bases
Replacement chair bases are a practical solution for office chair repairs and refurbishment. A strong base helps support the chair, distribute weight evenly and keep the chair balanced during everyday use.

Office chair repairs
Medium back office chairs
High back office chairs
Typist chairs
Task chairs
Call centre chairs
Home office chairs
Commercial office seating

5-Star Office Chair Bases
Many office chairs use a 5-star base design for stability and balance. This design helps spread weight across five points, making the chair more stable during normal office use.
Replacement 5-star chair bases are commonly used for standard office chairs, typist chairs, medium back chairs, high back chairs and other swivel chair designs.
Nylon and Chrome Chair Bases
Office chair bases are available in different materials depending on the chair type and usage requirements. Heavy-duty nylon bases offer a practical and cost-effective replacement option, while chrome chair bases provide a strong and professional finish.
These options are suitable for businesses, home offices and commercial environments that need reliable replacement parts.
Compatible Chair Base Replacements
Replacement chair bases are often used together with gas lifts and castors. When choosing a chair base, it is important to make sure it is compatible with the chair’s gas lift and wheel fittings.
A compatible base can help restore proper chair movement, height support and overall stability.

Frequently Asked Questions
What is an office chair base?
An office chair base is the lower part of the chair that supports the gas lift, castors and seat. It helps keep the chair stable and balanced during use.
When should I replace an office chair base?
You should replace an office chair base if it is cracked, broken, unstable or no longer supporting the chair safely.
Are office chair bases universal?
Many office chair bases are designed to fit standard gas lifts and castors, but compatibility can depend on the chair model and part size.
Can I replace only the chair base instead of buying a new chair?
Yes. If the rest of the chair is still in good condition, replacing the base can be a cost-effective repair option.
Do you deliver chair bases across South Africa?
Yes. Bum Seating supplies chair bases throughout South Africa, with delivery available to all nine provinces.
