Four functions share this outdoor umbrella base, working as a support for your shade, a side table with lid, a planter box without the lid, and a rolling stand that moves on two wheels with integrated handles. The 21 x 21 x 17.5 in frame includes a 21 x 21 in table tray and a 21 x 21 x 12 in planter box area to hold snacks, drinks, or plants within easy reach. Inside, a 17.5 x 18 x 9.5 in interior and weighted bag accept up to 175 lbs of sand or 14.5 gallons of water to stabilize 6-10 ft market, patio table, and offset umbrellas. Two adapters fit 1.5 in and 1.9 in poles, while dual hand-turn handles and the tray clip lock the pole in place to reduce wobble. The HDPE body with reinforced grooves and a powder-coated metal support pole is built for outdoor use and resists rust and aging, while a bottom drainage hole helps prevent water buildup around plant roots.
