Using this chair is super easy. Just find a flat surface, place the chair on it, and you're ready to sit. It's designed for commercial use, so it can handle a lot of traffic in places like restaurants, event halls, or offices. When stacking the chairs, make sure to stack them carefully up to a maximum of 25. This will keep them stable and prevent any accidents. As for maintenance, you can clean the chair with a mild soap and water solution. Use a soft cloth to wipe the black plastic back and seat, and the titanium gray powder - coated frame. Avoid using harsh chemicals as they might damage the finish. If there are any scratches on the frame, don't worry too much as it has a limited lifetime warranty. Just store the chairs in a dry place when not in use to prevent any rust or damage.
