We have an 11 ft heavy umbrella that went through the middle of our patio table. We put a canopy over the table and wanted the umbrella free-standing to move around and provide more shade. We filled the base with sand and couldn't be more pleased. It is really easy to move around and is providing the shade we need. I was told by 2 friends that I needed to have the umbrella go through the table to keep it standing, but not so. This is perfect and highly recommended.
