Using these chairs is a breeze. Just place them where you want for your indoor or outdoor dining or relaxation. They're stackable, so when not in use, you can stack them up to save space. As for the cushions, the tie - on design keeps them in place. When it comes to cleaning, the zippered covers on the cushions can be wiped clean with a damp cloth. If they're really dirty, you can take them off, hand - wash them, and then let them air - dry. Remember, these chairs are made to resist fading and weather, but it's still a good idea to store them indoors during extreme weather conditions to make them last even longer. And since they have a static weight capacity of 350 lbs, make sure not to exceed this limit to keep the steel frame in good shape.
