Office Chair Bases

Replacement Bases for Office Chairs

Find a replacement office chair base for your workplace or home office. Compare the sizes and finishes in this collection, including nylon and metal options, and match the base to your existing chair before ordering.

Check the Fit Before Buying

Measure the overall base diameter and check the connection to the gas lift and castors. A similar appearance does not guarantee that parts are interchangeable. Confirm the product dimensions, material and stated load requirements against your chair's specifications.

If you are unsure which base to choose, send our team the chair model, clear photographs and measurements with your quotation request. For several chairs, include the quantity and delivery address so we can help you compare suitable options.
