Office Chair Bases
Find a replacement base for your office chair
Browse office chair bases at Bum Seating for replacing the base of an existing chair. A suitable replacement needs to match the chair's gas lift, wheel or glide fittings and overall requirements. Use measurements and product specifications to choose a compatible part.
Check the fittings and dimensions
The appearance of a base is not enough to confirm compatibility. Compare the centre connection, the overall base size and the connections at the ends of the legs. Also check the material and any stated load specification on the product.
- Identify the original chair or base model where possible.
- Compare the gas-cylinder connection with the replacement specification.
- Check castor or glide fittings and whether these parts are included.
- Confirm the base dimensions suit the complete chair.
Match the connected components
If you also need wheels or fixed feet, see office chair castors and glides. Browse gas cylinders for the height-adjustment component, or return to all office chair parts. Ask Bum Seating for help if a fitting or measurement is unclear before ordering.
