Our raised bed is painted in a pleasant green colour, and is made from steel which is strong as well as lightweight. Measuring a generous 100cm by 30cm deep, it is easy to put together with just nuts and bolts (you will need a screwdriver and a pair of pliers). If 30 cm is too high, the bed can be easily dug into the ground to reduce the height. If you would like to protect your metal raised bed during the winter, then this cover is purpose made for the task. Made from strong woven 130 gsm polyethylene it is both durable and waterproof. Measuring 103cm in diameter and 20cm in depth, it's the perfect fit for our metal raised bed. The cover features metal eyelets and a nylon draw string to help secure it in place.
