Using this commercial-grade stack chair is easy. Just place it where you need seating, and you're good to go. Since it's fully assembled, you don't have to worry about putting it together. When you're done using it, stack up to 4 chairs to save space. For cleaning, simply wipe the black plastic back and seat with a damp cloth. Avoid using abrasive cleaners as they may damage the finish. Keep the chair away from sharp objects that could scratch the frame or seat. The frame has a limited lifetime warranty, so if you notice any issues, contact our customer service. Store the chair in a dry place to prevent rusting of the frame and deterioration of the plastic parts.
