Do you roll over wood, parquet, tiles or stone? This set of 5 white castors with rubber tread fits your Sitness Life 20, 40 or 50 from Topstar.
When do you choose this product?
When do you need special office chair castors?
These Topstar castors are specially developed for hard floors such as parquet, tiles and stone. If you notice that your current castors leave scratches on your beautiful floor or roll too hard, then these rubber castors are the solution. They protect your floor and ensure more stable movements of your office chair.
Why choose this size and finish?
With a diameter of 65 mm and a stem diameter of 11 mm, these castors fit perfectly in the standard sockets of Topstar office chairs. The grey rubber treads offer optimal grip and prevent your chair from sliding away unintentionally while you work. The set of 5 pieces means you can replace all the castors at once for a uniform result.
An honest explanation about the rubber property
The rubber treads make these castors softer than standard plastic variants, which has both advantages and disadvantages. They roll more quietly and protect your floor better against scratches, but they may require more force when moving your chair. This makes them ideal when floor protection is more important than easy rolling.
Check compatibility
These castors are specifically suitable for the Topstar models Sitness Life 20, Sitness Life 40 and Sitness Life 50. Check your chair model before ordering, as the 11 mm stem diameter does not fit all office chairs. If in doubt, you can measure the diameter of your current castors or consult the type plate under your chair.
