Combine umbrella support, outdoor surface space, and ballast storage in one compact 15 in square design. This SUGIFT 3-in-1 unit features a 2 in center opening for most standard market umbrella poles and a 14 in sleeve that helps support the pole along its length. Fill the interior with the included water bag or dry sand to provide up to 53 lb of hold-down weight, or leave it empty for easier repositioning. The 16.5 in tabletop offers convenient space for a drink, phone, or other small essentials beside a lounge chair. Its molded HDPE shell is designed for outdoor use in sun, rain, and frost, while the white finish complements patios, decks, pool areas, and other outdoor spaces. The unit arrives assembled and wipes clean for easy care.
