Using this chair is super easy. Just place it where you want, whether it's inside your home or outside on your patio. Since it doesn't require assembly, you can start using it right away. When it comes to weight, it can hold up to 400 LBS, so most people can sit on it comfortably. Remember, the fixed floor glides are there to protect your indoor floors, so don't try to remove them. For stacking, you can stack up to 5 chairs high, but make sure they are on a flat surface to avoid them falling over. To keep your chair looking great, wipe it clean with a damp cloth regularly. The black metal frame won't rust, but if it gets dirty, just a little wipe will do. And the natural PE cane rattan is fade - resistant, but try to avoid leaving it in direct sunlight for too long to keep its color looking nice. Also, be aware that the item description might mention features from other variants of this product, so check carefully if you have specific requirements.
