Using this chair is a breeze! Just pull it out from the stack and place it where you need it. Since it doesn't require assembly, you can start using it right away. When stacking, make sure to align the chairs properly to avoid any wobbling. For cleaning, simply wipe the black plastic seat and back with a mild soap and water solution. Don't use abrasive cleaners as they might scratch the plastic or damage the black powder - coated frame. If the chair gets wet, the vented design will help it dry quickly. Keep it in a dry place to prevent rusting of the steel frame. Also, don't overload the chair beyond its 880 - pound capacity to ensure its long - term stability and safety.
