Using this stack chair is a breeze. Just place it where you need it, and you're ready to sit. For storage, stack up to 25 chairs together to save space. When it comes to cleaning, use a mild soap and water solution to wipe down the gray plastic back and seat. Avoid using abrasive cleaners as they may damage the finish. Make sure to regularly check the front cross brace and the sled base frame for any signs of wear. If you notice any issues, contact our customer service as the frame has a limited lifetime warranty. Keep the chair away from sharp objects to prevent scratches on the black powder-coated frame. That's all you need to know to enjoy your stack chair for a long time!
