Four universal wheels, including two lockable casters, let you roll this wood elevated planter bed across a patio, balcony, or greenhouse and then secure it in place while you work. The 33-in high frame reduces bending as you tend vegetables or flowers in the 45 x 21 x 8 in planter box, which holds up to 132 lbs of soil and plants. Built-in drainage holes and the included liner help protect the pine wood while letting excess water escape. A 43.5 x 22 in bottom shelf supports 44 lbs to keep tools and extra pots close at hand.
