Using your new stack chair is easy. Just place it on a flat surface and you're ready to sit. It's great for commercial spaces like offices, cafes, or event halls. When you're done using it, stack it up with other chairs to save space. You can stack up to 25 chairs together. Make sure to place the chairs on a stable floor to avoid any tipping. Avoid dragging the chair on rough surfaces as it may damage the plastic ganging floor glides. To clean the chair, simply wipe the blue plastic upholstery and black plastic back and seat with a damp cloth. For the chrome frame, use a mild metal cleaner. This will keep your chair looking great and functioning well for a long time.
