Office Chair Scratching Floor

The scratching of floors by office chairs is mainly related to the wheel material, adjustment of the pneumatic rod, and usage methods, and can be resolved by replacing the wheels, adjusting the pneumatic rod, repairing scratches, and enhancing prevention measures.

I. Wheel Material Issues and Solutions

Hard wheels (such as PP/PU hard wheels, nylon wheels) are black in color, hard in texture, smooth on the surface but lack elasticity. Over time, rolling can easily trap sand particles, which act like sandpaper and wear down the floor, especially wooden and tiled floors. Solutions: Replace with soft PU wheels, whose outer polyurethane material is elastic and can cushion pressure, reducing scratches; if not replacing the wheels immediately, add silicone or fleece protective covers, or lay PVC mats or carpets to isolate friction. Soft PU wheels roll gently and quietly, and are less likely to scratch the floor, making them suitable for long-term use.

II. Pneumatic Rod Issues and Solutions

If the height of the pneumatic rod is adjusted too high or too low, the exposed metal part of the rod can rub against the ground; if the pneumatic rod ages (such as seal failure) or the base deforms, the rod body can sink and scratch the ground. Solutions: Immediately adjust the seat height to the middle position (with the backrest at a 90° angle to the knees) and observe if the scratching disappears; check if the base screws are loose and tighten them with an Allen wrench; if the problem persists, add a nylon washer at the bottom of the pneumatic rod for cushioning, or contact the manufacturer to replace it with a pneumatic rod designed with explosion-proof steel plate (with a built-in rubber cushion layer at the bottom).

III. Repairing Existing Scratches

For minor scratches, use toothpaste to wipe them by applying toothpaste to the scratched area and rubbing repeatedly with a towel; or use a touch-up pen, choosing one close in color to the chair, and apply it evenly to the scratched area. For deeper scratches, gently sand them with a wooden piece and then apply a layer of wax to cover them; or contact a housekeeping company or repair personnel to handle them with specialized tools and techniques.

IV. Preventive Measures

For daily maintenance, regularly clean the floor to prevent sand particles from embedding in the wheels; avoid using excessive force when moving the office chair to reduce wear; for wooden or painted floors, avoid cleaning with chemical solvents such as alcohol or gasoline. For long-term protection, lay transparent PVC mats or carpets to isolate direct contact between the wheels and the floor; regularly apply floor polish to enhance surface wear resistance.
