Using these dining chairs is easy. Just place them around your dining table and you're ready to enjoy your meals. When sitting, the high backrest will support your back comfortably. Make sure to place the chairs on a flat surface to avoid any wobbling. As for maintenance, you can use a soft, dry cloth to wipe off any dust regularly. If there are stains on the grey fabric, use a mild detergent and a damp cloth to gently clean the area. Avoid using harsh chemicals as they might damage the fabric. Also, try not to place the chairs in direct sunlight for long periods to prevent the fabric from fading.
