Using these chairs is a breeze. Just place them where you want to sit, whether it's outside in your garden or inside a sunroom. When not in use, stack them up easily as they are designed to stack up to 4 units. Be careful when moving them around with the plastic floor glides, as they are there to protect your floors. To maintain these chairs, clean the red Textilene fabric regularly with a mild soap and water solution. Wipe down the black powder - coated frame with a soft cloth to keep it looking new. Store them in a dry place during harsh weather conditions to extend their lifespan.
