Set of rubberized castors for hard flooring
The castors are designed for hard flooring (wooden floors, parquet, laminate). The office chair castors are made of thermoplastic elastomer, sometimes called thermoplastic rubber. These rubberized castors are softer and do not scratch hard flooring. By pulling out the old chair castors with a firm movement, you will be able to insert the new replacement castors with a circular motion.
Most executive, active seating, ergonomic or XXL office chairs are more massive and these 65 mm diameter castors are suitable. We also recommend these castors for chairs with a very small gap between the bottom of the pneumatic lift and the floor.

Please take note what castors you have now
When buying an office chair, you should pay attention to the castors included with the chair. Often these are plastic castors for soft floor surfaces (carpet). If the chair will be used on hard flooring, the surface may be damaged or scratched over time.
Measure the size of the axle before ordering!
For most of the chairs we sell, these 10 mm castors are suitable (check the description of the chair), but if you are choosing castors for a chair from another retailer, then please measure the castor axile diameter carefully. By pulling out the old castors of the chair with a firm movement, you will be able to easily measure the diameter of the axle.
A plastic mat under the chair can be purchased for additional protection of the floor surface.
If you prefer a stable, fixed seating position, we recommend purchasing chair feet instead of castors.
