Two usable surfaces stack into a footprint of just 17.72 by 14.96 inches here, with a 17.32 inch height that matches the arm of most patio chairs and loungers. The tabletop measures 17.72 by 14.96 inches at 1.65 inches thick and carries up to 360 pounds, enough for a cooler, a planter or a stack of tools rather than only a drink. Below it a 14.57 by 11.81 inch shelf holds another 160 pounds, keeping sunscreen, books, towels or garden gloves off the deck boards. High-density polyethylene forms the whole table, a material that stays watertight, resists dampness and holds color instead of chalking after a summer of sun. An H-frame structure spreads the load between the two levels so the table stays level on pavers, decking or a pool surround. At 13 pounds it lifts easily to a new spot and works indoors in a bathroom or entry as well.
