Using this outdoor umbrella base is easy. First, take it out of the box and follow the step - by - step instructions to assemble it. Once assembled, choose the right sizing insert that fits your umbrella. Place the insert in the base and then insert your umbrella into the base. Use the adjustable tightening knob to secure the umbrella firmly. When using it, make sure to place it on a flat and stable surface to prevent it from tipping over. As for maintenance, since it's made of powder - coated polyresin, it's quite durable. You can simply clean it with a mild soap and water solution. In case of bad weather, it's a good idea to bring the umbrella and base indoors or cover them to extend their lifespan. Remember, due to COVID - 19, there might be some delays in shipping, so plan ahead.
