Using these chairs is a breeze. Just place them where you want, whether it's inside your cafe or outside on your patio. Since they don't require assembly, you can start using them right away. When it comes to stacking, remember not to stack more than 5 chairs high to keep them stable. Each chair can hold up to 400 LBS, so make sure not to overload them. The fixed floor glides are there to protect your indoor floors, so be careful not to remove them. For cleaning, simply wipe the chairs with a damp cloth. They're made with fade - resistant PE rattan and rust - free aluminum frames, but it's still a good idea to keep them out of extreme weather conditions if possible. This will help keep your chairs looking great for a long time.
