Using these chairs is easy - just pull them up to your dining table and take a seat. When you're done using them, simply push them back under the table. For assembly, follow the detailed installation manual and use the included tools. Make sure all parts are securely fastened. As for maintenance, wipe the fabric part with a soft, damp cloth regularly to keep it clean. Avoid using harsh chemicals as they may damage the fabric. If there are any spills, clean them up right away. For the metal legs, a dry cloth can be used to remove dust. Keep the chairs away from sharp objects to prevent scratches on the fabric and metal.
