Using these dining chairs is a breeze. Just place them around your dining table, and you're ready to enjoy your meals. For the best experience, make sure the chairs are on a flat surface to prevent wobbling. When it comes to cleaning, if you have the PU leather upholstery, a mild soap and a damp cloth are all you need. Gently wipe the surface and dry it with a soft towel. For the linen upholstery, spot - clean any stains with a gentle fabric cleaner. Avoid using harsh chemicals as they might damage the material. As for maintenance, check the legs and joints periodically to ensure they are tight. If you notice any loose parts, use a screwdriver to tighten them up. Also, try not to exceed the 250 - lb weight capacity to keep the chairs in good condition for a long time.
