There are a few key factors you ought to consider when you’re buying the bases for the umbrellas. Firstly, you shouldn’t pick a very heavy model. Secondly, consider how you’re going to use them. If you’re planning to use a centre pole or cantilever model, then you can choose the base that weighs ranging from 30kg to 120kg. Similarly, the most common sizes for parasol poles vary from 38mm to 48mm in diameter. Also, make sure to buy the right base for narrow spaces. In short, you need to own a parasol that’s ideal for your outdoor space.
