A solid choice for durability and function. This raised garden bed is strong， long and perfectly square. Reinforced with bracing boards to prevent frost push-out or any disturbance from mowers or rambunctious children and pets. If you like an organized garden， you'll appreciate how the bracing boards divide your garden into three separate planting areas. The 11 in. high stacked side boards give you lots of depth to grow both underground veggies， as well as tall plants. As shown， your 4' x 12' x 11 in. raised garden bed provides 48 sq. ft. of planting area. Screw-on joints make it simple to install. Your kit comes with everything you need except the soil and plants. Each modular kit includes eighteen of our 1 in. Classic Sienna composite boards， fourteen 1 in. screw-on stacking brackets and two 1 in. screw-on 4-Way bracing brackets. The insulating open-channel boards trap air， providing insulation to your soil. Keeps soil warmer in the Spring and Fall， and cooler in the Summer， so you can grow for an extended period. Stacking brackets allow you to install the second layer of your garden just by inserting the stakes into the brackets below. Brackets pivot 270°， allowing endless design options. You can easily convert your bed to an octagon， just by changing the angle of the brackets.
