Anyone that has a large outdoor patio furniture or lawn umbrella should also have a sturdy umbrella base to secure the umbrella pole. A large, unsecured umbrella can be damaged, damage other property or even injure nearby persons if it is picked up by the wind and thrown across the lawn. Bases are available in many different styles and are made from a variety of materials, each with their strengths and weaknesses.
Many bases are made from plastic in a hollow form that is filled with sand or water in order to make them as heavy as needed. A typical plastic or resin-formed umbrella base will weigh about three pounds empty but as much as fifty pounds full of sand or water.
More elaborate bases are produced from materials such as wrought iron, steel, or brass. These metal bases provide enough weight and support to hold an umbrella in place and, though less economical, generally provide a more sophisticated look to compliment the rest of the lawn furniture.
Whatever material is chosen, the umbrella base should be stable enough so that the umbrella isn’t subject to tipping over or taking flight in heavy winds.
