Using these dining chairs is a breeze. Just place them around your dining table, and you're ready to enjoy your meals in style. When sitting, you'll notice the ergonomic design provides great support. For cleaning, use a soft, damp cloth to wipe the black leatherette upholstery. Avoid using harsh chemicals as they might damage the material. If there are any spills, clean them up right away to prevent stains. In terms of placement, these chairs are suitable for various modern dining room settings, but try to keep them away from direct sunlight for long periods as it could fade the leatherette. With proper care, these chairs will continue to enhance your dining experience for years to come.
