Using these dining chairs is a breeze. Just place them in your desired location - whether it's your kitchen, bedroom, or office. When you receive the chairs, they'll come with assembly instructions and tools. It usually takes about 10 - 15 minutes to put them together. Make sure to follow the instructions carefully to ensure a proper setup. As for maintenance, use a soft, dry cloth to wipe the polyurethane leather backrest and the seat regularly. Avoid using harsh chemicals or abrasive materials as they can damage the leather. If there are any spills, clean them up immediately. Also, keep in mind that the colors of the chairs may look a bit different from what you see on your screen. And be aware that the item description might refer to features of other variants, especially those with different fabric patterns or shapes.
