Casters under this planter let you chase the sun across a patio or roll the whole thing indoors when the forecast turns, and 2 of the 4 wheels lock so it stays put once positioned. The planting bed is deep enough for real root growth and carries up to 66 pounds, while the climbing trellis above holds another 11 pounds of vines or a hanging pot. The frame stands 50 inches tall on a 25 by 11 inch base, narrow enough for an apartment balcony. Fir wood was used for its hardness and resistance to deformation over long outdoor use. Drainage at the bottom of the bed clears excess water. The assembled planter weighs 11 pounds.
