Using the Nardi Rio 140 Aluminum Extendable Table is easy. To adjust the size, simply extend or retract the table according to how many people you're hosting. You can seat 6 - 8 people when it's fully extended. When using it outdoors, don't worry about the weather as it's weather - resistant. But it's a good idea to cover it during extreme weather conditions. For cleaning, just wipe the smooth surface with a damp cloth. You can use a mild soap if there are stubborn stains. Remember, the table requires assembly. Follow the assembly instructions carefully to ensure it's set up correctly. Keep it in a dry place when not in use to prolong its lifespan.
