With an easy-to-fill spout, the base can be filled with water or sand to enhance stability and wind resistance. Note that the base is surprisingly lightweight before being filled. It also features a hidden handle for easy transport, and the four plates are stackable for convenient storage. Say goodbye to unstable umbrella stands that topple in strong winds.
