The Patent Pending Handy Bed is constructed of maintenance free and durable PVC (Vinyl) that will NEVER ROT like wood, and offers a Lifetime Warranty against peeling, flaking, blistering, corroding, rotting, fading and manufacturing defects. Its simple design allows almost anyone the ability to assemble in minutes with only a Phillips screwdriver or cordless drill with Phillips bit (recommended). Its 6" depth is adequate for growing most veggies and flowers. The bed can be placed at any level location where adequate sunlight for desired plants is available. The PVC is self cleansing from the rain or simply use a garden hose to spray off excess dirt. For stubborn stains, use soap and water. This bed is stackable with another Handy Bed by aligning the tongue and groove joints allowing the next Handy Bed to sit right on top of the lower unit for more soil depth and/or tiering. The elements associated with weather, soil and water make PVC the right choice for your raised beds to endure many years of successful growing.
