When you click on the parasol, a matching base will be suggested.
If you only want to order a base, please take into account that the base has to have enough weight to support your parasol.
Parasols of 4m oct, 3,5m square and 2.8m square need a base of 65 kg.
Parasols of 2.2m square, 3,2m oct need a base of 45 kg.
Also check the pole diameter of your parasol.
