Maintenance
Cleaning the PU Leather
The chair's premium PU leather upholstery is waterproof and easy to clean.
- Wipe spills immediately with a soft, damp cloth.
- For general cleaning, use a mild soap solution and a soft cloth. Avoid harsh chemicals or abrasive cleaners, as these can damage the material.
- Dry thoroughly after cleaning.
General Care
- Periodically check all screws and bolts to ensure they are tight. Retighten if necessary.
- Clean the casters regularly to remove hair, dust, and debris that may hinder smooth rolling.
- Avoid exposing the chair to direct sunlight or extreme temperatures for prolonged periods, as this can cause the material to fade or crack.
