Using these dining chairs is a breeze. Just assemble them using the included installation accessories, which should take about 10 - 15 minutes. Once set up, you can place them around your dining table and enjoy a comfortable meal. When it comes to maintenance, use a soft, damp cloth to wipe the PU leather cushion regularly to keep it clean. Avoid using harsh chemicals as they may damage the leather. For the metal legs, check for any signs of rust from time to time. If you notice any, you can use a metal cleaner to remove it. Also, be aware that the actual product colors may vary a bit due to your screen settings. And remember, the item description might mention features from other variants of this product, especially those with different fabric patterns or shapes.
