Using your new Commercial Grade Thonet French Bistro Stacking Chair is a breeze. You can place it anywhere, indoors like in a bistro or outdoors on a patio. Since it comes pre - assembled, you can start using it right away. When it comes to stacking, you can stack up to 5 chairs high, but be careful not to stack more to avoid any potential damage. For weight, it can hold up to 400 LBS, so make sure not to exceed this limit. The fixed floor glides are there to protect your indoor floors, so don't remove them. To keep your chair looking great, simply wipe it clean with a damp cloth. Avoid using harsh chemicals as they might damage the black and white PE rattan or the non - rusting black metal frame. Also, store the chairs in a dry place if possible to maintain their quality over time.
