Using your Nizuc outdoor corner chair is a piece of cake. First, assemble it as per the included instructions. It requires some assembly, but it's straightforward. Once it's put together, you can start creating your custom seating group. Use the attachment latches under the seats to connect different pieces and make the configuration you like. When it comes to maintenance, the waterproof fabric is easy to clean. Just wipe it down with a damp cloth and mild soap. For the aluminum frame, you can use a regular metal cleaner to keep it shiny. Keep in mind that although the fabric is waterproof, it's still a good idea to cover the chairs during extreme weather or when not in use for a long time. This will help extend their lifespan and keep them looking great for years.
