MDF (medium-density fibreboard) is a synthetic product that comes in flat boards. Made up of dried sawdust and wood shavings, and held together by resins and wax, it can come in an array of veneers. It has a very smooth, even finish with no noticeable knots or grains, making it good for painting or varnishing. Left bare, it can resemble any natural material from solid wood to concrete.

An MDF board is hard to break and is actually stronger and heavier than most varieties of wood. Under pressure, timber splinters and cracks, but MDF retains its form – even when exposed to heat and moisture – making it incredibly durable and versatile. Only extreme water damage or heat can destroy its structure (although you can purchase MDF boards that are resistant to both).
