Using these chairs is a breeze. Just place them in your desired outdoor or indoor location and start enjoying. When not in use, you can stack them up to 8 high for easy storage. Since they're fully assembled, there's no need for you to waste time putting them together. Remember, although these chairs have a 300 lb. seating capacity, avoid overloading them. For indoor use, the plastic floor glides will protect your floors. To keep your chairs looking great, clean them regularly with a water - based cleaner. Store them in a dry place during harsh weather to extend their lifespan.
