Using your Christopher Knight Home® Waterford Outdoor Aluminum Dining Chair Set is a breeze. First, assemble the chairs as per the included instructions. Once they're set up, place them in your desired outdoor spot, like on a patio or by the pool. Sit back, relax, and enjoy your outdoor meals or just some quiet time. When it comes to maintenance, the water - resistant cushions are easy to clean. Just wipe them with a damp cloth if they get dirty. The aluminum frames are durable, but it's a good idea to clean them with a mild soap and water solution occasionally to keep them looking great. Make sure not to exceed the 300 lbs weight limit on each chair to avoid any damage. If the chairs are going to be left outside during harsh weather, consider covering them to extend their lifespan.
