Using these chairs is a breeze! Just place them wherever you need seating, whether it's inside your café or outside on the patio. They're ready to use right out of the box since no assembly is required. When it comes to weight, these chairs can handle up to 400 lbs, so they're suitable for a wide range of people. You can stack up to five chairs on top of each other, which is great for storage when you're not using them. Make sure to use the fixed floor glides to protect your indoor floors. As for maintenance, it's super easy. Just grab a damp cloth and wipe the chairs clean whenever they get dirty. Also, keep in mind that the metal frames have a natural bamboo finish and won't rust, but try to avoid leaving them in extremely wet conditions for a long time to keep them in top shape.
