Using this stack chair is easy. Just place it where you need seating in your commercial space. Since it comes fully assembled, you can start using it right away. When stacking, you can stack up to 20 chairs together. Remember, the chair has a weight capacity of 880 lb, so don't exceed this limit to ensure safety. For maintenance, clean the blue plastic back and seat regularly with a mild soap and water solution. The vented holes on the back and seat help with drying, but avoid leaving the chair in wet conditions for a long time. The black powder - coated frame is durable, but try to prevent it from getting scratched. If you have any issues with the frame, you're covered by a limited lifetime warranty.
