Using these patio armchairs is a breeze. Just place them in your desired spot on the deck, backyard, sunroom, or dining room. They're ready to use right out of the box as no assembly is required. When it comes to cleaning, simply wipe them down with a damp cloth to keep them looking good. As for weight, each chair can hold up to 350 LBS of static weight, so be mindful not to exceed this limit. Since the frames are fade and weather - resistant, they can stay outdoors year - round. However, if there are extremely harsh weather conditions, it might be a good idea to cover them. The high - density foam cushions are all - weather, but it's still best to keep them dry as much as possible to maintain their plushness.
