Using these dining chairs is a breeze. Just place them around your dining table and start enjoying your meals. When sitting, the ergonomic backrest will support your body well. For cleaning, simply wipe the PU material with a soft, damp cloth. Avoid using harsh chemicals as they may damage the material. To maintain the chairs' stability, periodically check the connection between the legs and the seat. Keep the chairs away from sharp objects to prevent scratches on the PU surface. Also, don't overload the chairs as they have a certain load - bearing limit. With proper care, these chairs will serve you for a long time.
