One hundred gallons of sealed storage in a 47.5-in x 21-in x 24-in box covers a season of cushions plus the pool skimmer and a bag of chemicals. The lid seats on a weatherproof PP shell and takes 310 lbs, rated for two people, which makes the box a bench along a deck rail. Inside, 46-in x 23-in x 19-in of clear space swallows long items that will not fit in a round bin. A lockable latch secures the contents, and metal reinforcement inside the walls keeps the panels from bowing when the box is filled to the brim. The molded surface resists fading and warping, and drains rather than holding water on top. Assembled it weighs 27 lbs, light enough to slide against a wall.
