Using these chairs is a breeze. You can place them indoors for a cozy dining experience or outdoors on your patio. Since there's no assembly needed, you can start using them right away. When it comes to stacking, you can stack up to 5 chairs high to save space, but make sure the stack is on a flat surface. For indoor use, the fixed floor glides will protect your floors, so no need to worry about scratches. To keep these chairs in top condition, just wipe them with a damp cloth regularly. Avoid using harsh chemicals as they might damage the PE rattan or the aluminum frame. Also, if you're using them outdoors, it's a good idea to bring them inside during extreme weather to extend their lifespan.
